Where does the wood we use come from?

Distribution of timber resources in my country

① The Greater and Lesser Khingan Mountains and Changbai Mountains in the northeast are the largest natural forest areas in my country;

② The Hengduan Mountains in the southwest are the second largest natural forest areas in my country. Large natural forest areas;

③ The mountainous areas of Taiwan, Fujian, Jiangxi and other provinces in the southeast are dominated by artificial forests and secondary forests.

Yichun City in Heilongjiang Province is a famous forest industry city in China. In the 50 years since the founding of the People's Republic of China, it has delivered a total of 240 million cubic meters of wood to the construction of the motherland, and is known as the "Forest City of China". The Wuying District of Yichun City has the world's original virgin red pine forest reserve.

Word: Timber

Pinyin: mùcái

Basic explanation

[lumber; timber; wood] Preliminary processing after harvesting of trees Tree trunks or large branches

Detailed explanation

After trees are felled and preliminary processed, they can be used for construction and making utensils.

"Zhou Rites·Local Officials·Commissioners": "In funerals, the salary is steamed and wood is used, and in military affairs, the salary is accumulated and cut." Guo Moruo's "Boyhood" Chapter 13: "Then, layer by layer, we use large stones, fine stones, wood, tile powder, etc. to fill up the pit."

Timber generally refers to wooden materials used in industrial and civilian construction, and is often referred to as Divided into soft materials and hard materials. The wood used in the project is mainly taken from the trunk parts of trees. Because wood is easy to obtain and process, it has been a major building material since ancient times. Please refer to Ningbo Aijia Luke Wood Panel Co., Ltd.

Wood is classified according to tree species, and is generally divided into coniferous trees and broad-leaved trees.

Overview

Wood is a lignified tissue formed by plants capable of secondary growth, such as trees and shrubs. After the primary growth of these plants ends, the vascular cambium in the rhizome begins to move, developing bast outward and wood inward. Wood is a general term for plant tissues that develop inward from the vascular cambium, including xylem and thin-walled rays.

Wood plays a great supporting role in human life. Depending on the different properties of wood, people use them in different ways.

1. Types of wood

Wood can be divided into two categories: coniferous trees and broad-leaved trees. Fir and various pine, spruce and fir are coniferous trees; oak, ash, camphor, sassafras and various birches, nanmu and poplar are broad-leaved trees. There are many tree species in China, so the wood species commonly used in engineering projects vary from region to region. In the northeastern region, there are mainly Korean pine, larch (yellow pine), spruce, red bark spruce, and ash; in the Yangtze River basin, there are mainly Chinese fir and masson pine; in the southwest and northwest regions, there are mainly fir, spruce, and hemlock.

[Edit this paragraph] 2. Structure of wood

The trunk is composed of bark, cambium, xylem (i.e. wood) and pith. The growth rings surrounding the pith can be seen in the xylem of a cross-section of a tree trunk. Each annual ring is generally composed of two parts: the light-colored part is called early wood, which is grown in the early part of the season and has larger cells and sparser material; the darker part is called late wood, which is grown in the late season and has thinner cells. Small, dense material. Some woods are darker in color in the middle of the trunk, called heartwood; and lighter in color at the edges, called sapwood. Coniferous wood is mainly composed of tracheids, wood rays and axial parenchyma, which are arranged regularly and the material is relatively uniform. Broad-leaf tree wood is mainly composed of vessels, wood fibers, axial parenchyma, wood rays, etc., and has a complex structure. Because the cells that make up wood are directionally arranged, there is a difference between along and transverse grains. The transverse grains can be distinguished as the radial direction that is consistent with the wood rays and the chord direction that is perpendicular to the wood rays. Coniferous trees generally have tall trunks, straight texture, are easy to process, easy to dry, have little cracking and deformation, and are suitable for structural timber. Some broad-leaved trees have hard texture, beautiful texture and color, and are suitable for decoration materials.

[Edit this paragraph] 3. Defects of wood

Also known as defects, they can be divided into three major categories:

① Natural defects. Such as wood knots, diagonal grain and defects caused by growth stress or natural damage.

Knots are the parts of branches that are enclosed in xylem as the tree grows. The diagonal grain of logs is often called twist grain, and for sawn timber it is called twill grain.

② Biologically harmful defects. Mainly include decay, discoloration and insect infestation.

③ Defects caused by drying and mechanical processing. Such as dry cracking, warping, saw wounds, etc. Defects reduce the use value of wood.

In order to use wood rationally, the type, size and number of allowable defects in wood are usually limited according to the requirements of different uses, and the wood is divided into grades. Rotten and insect-eaten wood is not allowed to be used in structures, so the defects that affect the strength of the structure are mainly knots, diagonal lines and cracks.

4. Physical properties of wood

The main physical properties of wood are:

① Density. Refers to the weight per unit volume of wood. Both the weight and volume of wood are affected by moisture content. The ratio of the oven-dried weight of a wood sample to its volume when saturated with moisture, the oven-dried volume, and the oven-dried volume are called basic density, absolute dry density, and oven-dry density respectively. The ratio of the weight of wood after air drying to the volume after air drying is called the air dry density of wood. Wood density varies with tree species. The air-dry density of most wood is about 0.3 to 0.9 g/cm3. Wood with higher density generally has higher mechanical strength.

② Moisture content of wood. Refers to the weight of water in wood as a percentage of the weight of dry wood. The moisture in wood can be divided into two parts. One part exists within the cell walls of the wood and is called adsorbed water; the other part exists between the cell cavity and the intercellular space and is called free water (free water). When the adsorbed water reaches saturation and there is no free water, it is called the fiber saturation point. The fiber saturation point of wood varies depending on the tree species, ranging from about 23 to 33%. When the moisture content is greater than the fiber saturation point, moisture has little effect on wood properties. As the moisture content decreases from the fiber saturation point, the physical and mechanical properties of wood change. Wood can absorb or evaporate moisture in the atmosphere and adapt to the relative humidity and temperature of the surrounding air to achieve a constant moisture content, which is called equilibrium moisture content. The equilibrium moisture content of wood varies with region, season, climate and other factors, and is approximately between 10% and 18%.

③ Swelling and shrinkage. Wood expands when it absorbs moisture and shrinks when it loses moisture. The drying shrinkage of wood from the fiber saturation point to furnace drying is about 0.1% along the grain direction, about 3 to 6% in the radial direction, and about 6 to 12% in the chord direction. The difference in radial and chordal drying shrinkage is the main cause of cracks and warping in wood.

5. Mechanical properties of wood

Wood has good mechanical properties, but wood is an organic anisotropic material, and the mechanical properties along the grain direction and across the grain direction are very different. difference. Wood has higher tensile and compressive strengths along the grain, but lower tensile and compressive strengths across the grain. The strength of wood also varies with tree species and is affected by factors such as wood defects, load action time, moisture content, and temperature. Among them, wood defects and load action time have the greatest impact. Due to the different size and position of the knots and the different force properties (tension or compression), the strength of knotted wood can be 30 to 60% lower than that of unknotted wood. The long-term strength of wood under long-term load is almost half of its instantaneous strength.

6. Wood processing, processing and application

In addition to using logs directly, wood is processed into boards, squares, or other products. In order to reduce the deformation and cracking of wood during use, boards and squares usually must be dried naturally or artificially. Natural drying involves stacking wood and air-drying it. Artificial drying mainly uses the drying kiln method, but simple baking and roasting methods can also be used. A drying kiln is a drying chamber equipped with circulating air equipment that can regulate and control the temperature and humidity of the air. The wood dried in the drying kiln is of good quality and has a moisture content of less than 10%. Wood that is prone to decay during use should be preservative treated in advance. The gluing method can be used to glue boards into large components, which can be used for wooden structures, wooden piles, etc. Wood can also be processed into plywood, particleboard, fiberboard, etc.

In ancient architecture, wood is widely used in temples, palaces, temple towers and residential buildings.

Among the existing ancient buildings in China, the most famous are the East Hall of Foguang Temple in Mount Wutai, Shanxi, built in 857 AD, and the Wooden Pagoda in Yingxian County, Shanxi, built in 1056 AD, with a height of 67.31 meters. In modern civil construction, wood is mainly used for building wooden structures, wooden bridges, formwork, poles, sleepers, doors and windows, furniture, building decoration, etc.

Wood identification

In order to prevent the majority of wood carving enthusiasts from being confused due to insufficient knowledge about wood when purchasing wood carving products. We introduce to you some of the more common characteristics of wood that are often used in wood carving crafts.

Rosewood

Among all kinds of hardwoods, rosewood has the most dense texture, the heaviest weight of the wood, and the wood grain is not obvious. When the flowers of rosewood are placed in white wine, the flowers will immediately decompose into pink and form a sticky gel with the wine, which can form a line when poured. This is an effective way to identify rosewood. Rosewood is mainly produced in India, but is also produced in my country's Yunnan, Guangdong and Guangxi. Two of them are distributed in my country: one is red sandalwood, commonly known as small-leaf sandalwood; the other is rosewood, commonly known as big-leaf sandalwood. Small-leaf sandalwood rarely has large materials, and the diameter of the material is usually less than 20 centimeters. No matter how large it is, it will be hollow and cannot be used. The small-leaf sandalwood grain is not obvious, the color is purple-black, and some are as dark as paint, and the texture is almost invisible. It is generally believed that the rosewood imported by China from India is rosewood, that is, big-leaf sandalwood. The texture of big leaf sandalwood is thicker and the color is lighter. After polishing, there are obvious wood lines, that is, brown eyes appear. Our country has believed that rosewood is the most precious wood since ancient times. Because it is so precious, there are fewer red sandalwood utensils than huanghuali. Although red sandalwood is not as gorgeous as huanghuali, its quietness and ancientness are incomparable to any wood.

Huanghuali

The color of this material is neither quiet nor noisy, just right. The texture is either hidden or visible, vivid and changeable. The color of rosewood ranges from light yellow to purple red. The wood is solid and the pattern is exquisite. It is in the shape of a figure. It is fragrant when sawed. The rosewood produced in Hainan, China is the best. Its distinguishing feature is that there are grimaces on the pattern surface, that is, the knots are the most important. The ones with thicker flowers and lighter colors are considered better. Another characteristic is that the heartwood and sapwood are very different. The heartwood is reddish brown to dark reddish brown or purple reddish brown, with uneven depth, often with dark brown stripes. Its sapwood is grayish brown or light yellowish brown. Huanghuali did not have this name in ancient times, only "Huali" or "Huazhu". Later, the name Huanghuali was mainly to distinguish it from the so-called "New Huali" because Hainan Huanghuali had been cut down as early as the end of the Ming Dynasty. Nowadays, most of the materials used are rosewood imported from Southeast Asian countries such as Myanmar, but there are many varieties and different qualities, and the quality varies greatly.

Chicken Wing Wood

Chicken Wing Wood belongs to the Red Leguminosae family, with about 40 to 60 species. There are 26 species in my country, mainly produced in Fujian Province. It was renamed because of its beautiful pattern that resembles chicken wings. Craftsmen generally believe that there are two types of chicken wing wood: new and old. New chicken wing wood has rough wood, purple and black, turbid texture, stiff and no tendency to rotate, and the wood fibers are sometimes prone to cracking and stubble. The texture of old chicken wing wood is fine and dense, with alternating shades of purple and brown. Especially in the longitudinal section, the threads are thin and floating, with a brilliant and shining brilliance like the head and wings of a bird. Most of the chicken wing wood currently on the market is new chicken wing wood.

Ironwood

Ironwood is also known as "iron plow wood" or "iron chestnut". It is the tallest among several hardwoods and is relatively cheap. Ironwood sometimes has patterns that resemble wenge but are thicker. In the past, furniture dealers used it to pass it off as wenge and sell it. Ironwood is a larger evergreen tree with an upright trunk, more than ten feet high and more than ten feet in diameter. Native to East India. It is distributed in both Guangdong and Guangxi: the wood is hard and durable, the heartwood is dark red, the color and texture are slightly like chicken wing wood, the texture is rough, the grain is thick, and the brown eyes are obvious. It is mostly used in construction in the tropics and is extremely durable.

Beech

Beech belongs to the elm species, which is produced in Jiangsu, Zhejiang and other places. It is also known as beech elm or big-leaf elm. The wood is hard and beautiful in color. It has a wide range of uses and is quite popular. It is valuable, and its old wood is reddish, hence the name "blood beech". Also called red beech. It is stronger than ordinary wood, but it cannot be regarded as a hardwood. Therefore, experienced craftsmen and true lovers of Ming-style furniture attach great importance to it and believe that its artistic and historical value should not be devalued because of poor materials.

Beech wood is hard, has beautiful color and grain, and has a very beautiful large pattern. The layers are like overlapping mountains, which are called "pagoda patterns" by carpenters.

Agarwood

Imported agarwood

Also known as agarwood, Yankou incense, Penglai incense, dense incense, Zhilan incense, green cinnamon incense, etc. The resinous heartwood from the agarwood plant of the family Thymeaceae. Mainly produced in Indonesia, Malaysia, Singapore, Vietnam, Cambodia, Iran, Thailand and other places.

The agarwood produced in Indonesia, Malaysia, and Singapore is customarily called Xinzhou Incense. It has the best quality, and its fragrance when burned is quiet and long-lasting. The agarwood produced in Vietnam is customarily called Hoi An incense, and its quality is inferior. It has a good burning fragrance and a sweet taste, but it does not last long.

Imported agarwood is mostly cylindrical or irregular rod-shaped, with a yellow-brown or gray-black surface. It is hard and heavy and can sink or semi-sink in water. It has a strong smell and produces thick smoke when burned. , strong aroma. Imported agarwood is slightly warm in nature and bitter in taste. It has the effects of promoting qi and relieving pain, warming and stopping vomiting, and relieving qi and relieving asthma. Its medicinal effect is better than that of white wood.

Domestic agarwood

Also known as agarwood, agarwood, ear incense, agarwood, white wood incense, Hainan agarwood, daughter incense, Wanxiang, Lingnan agarwood. The resinous heartwood from the Thymeaceae plant Agustium leucophylla.

Agarwood is divided into No. 1 incense (heavy quality and strong fragrance), No. 2 incense (firm in texture and strong fragrance), No. 3 incense (loose in quality and good fragrance), and No. 4 incense (floating in texture). , fragrant and light) in four specifications. Its shape is irregular, and its surface is mostly uneven like rotten wood, with knife marks, occasional holes, and alternating patterns of dark brown resin and yellow-white wood.

Ebony

Ebony belongs to the persimmon tree category and is mainly produced in India, Indonesia, Thailand, Myanmar and other countries. The difference between the heart and sapwood of ebony is obvious. The sapwood is white (with yellowish brown or greenish gray) to light reddish brown; the heartwood is black (chaotic black or slightly green jade) and the irregular black heartwood (its stripes are arranged alternately between dark and light). The wood is shiny and has no special smell. The texture is black and white, until shallow staggered, the structure is deep and even, corrosion-resistant, durable, hard, heavy and delicate. It is a very rare and precious material for furniture and handicrafts.

Green sandalwood

Green sandalwood mainly grows in subtropical areas, mainly in India, Vietnam, Africa, and also in Yunnan, my country, because of its hard wood, pleasant aroma, and colorful colors. , and is rich in a variety of trace elements needed by the human body. Among them, selenium and cobalt are anti-cancer substances. Their fragrance needs to be evaporated at temperatures above 35 degrees Celsius, while the normal body temperature of the human body is 37.5 degrees Celsius. Traditional Chinese medicine theory believes that the fragrance of sandalwood can calm the mind, soothe the mind, refresh the brain, and suppress evil. , Tongqiao, etc., so people often use it as a mascot, wear it themselves or give it as a gift to relatives and friends.

Sandalwood

Sandalwood is the core part of sandalwood, excluding the sapwood of sandalwood (which has no fragrance and is white). Sandalwood belongs to the genus Sandalwood of the family Santalaceae. It is a semi-parasitic small tree that can reach a height of 8 to 15 meters and a diameter at breast height of about 20 to 30 centimeters. The smaller ones are only 3 to 5 centimeters. The origin is the Gotavilia River Basin in India, south to Mysore and Indonesia, east and west Nusa Tenga and East Timor. Sandalwood is generally tawny or dark brown. Over time, the color becomes slightly darker, has a good luster, and the patina is not as obvious as that of red sandalwood or huanghuali. The aroma is mellow and lasts for a long time. It is not obvious after a long time. However, when scraped with a blade, the aroma is still strong. Compared with the pungent aroma of camphor and nan, sandalwood is divided into Laoshan, Xinshan and Dimen. Fragrant, pear scent.

Rosewood

There are many kinds of rosewood, which is a member of the Dalbergia genus of the Fabaceae subfamily. Among the plants of the genus Dalbergia, except Dalbergia dabergia in Hainan Island, which is called "fragrant branch" (commonly known as Huanghuali), the others all belong to the rosewood category. There are generally three types of rosewood, black rosewood, red rosewood, and white rosewood. Their unique characteristic is that they emit a smell of vinegar during processing, hence the name rosewood.

Among the three types of rosewood, black rosewood is the best. Its color ranges from purple-red to purple-brown or purple-black. The wood is hard and has good polishing effect. Some are very close to rosewood and are often mistaken for rosewood, but most of them have thicker textures.

The texture of red rosewood is more obvious than that of black rosewood. The texture is straight and the color is mostly maroon.

The color of white rosewood is much lighter than that of red rosewood, and its color is close to that of grass pear. Sometimes it is easy to be confused with grass pear.

Rosewood

Rosewood belongs to the genus Rosewood. Its wood is relatively hard, mostly red or reddish-purple in color, with clear texture and soft color. The color of the wood is When it is a little light, it is close to the center of the wood, but the color becomes darker toward the outside, which is red or reddish purple. In fact, this is the true color of rosewood.

Camphor wood

Camphor wood has a nice camphor-like fragrance. There are irregular longitudinal cracks. Grows on hillsides and streams; often cultivated. Mainly produced south of the Yangtze River and in the southwest. The wood blocks vary in size, with a reddish-brown to dark brown surface, and growth rings can be seen in the cross-section. Heavy and hard. It tastes cool and spicy. Camphor wood has the effects of treating rheumatism, clearing meridians, relieving pain, and digesting food.

Boxwood

Boxwood is a small tree with a hard texture and very bright colors, some of which are egg yellow. Because it is difficult to grow, there is no aniseed, and it is often used to make wood. Combs are used for engraving, and for furniture, they are mostly used as inlay materials.

Boxwood is a common evergreen plant in tropical and temperate zones. It is widely distributed in the southeastern coast of my country, southwest and Taiwan.

There are more than 100 tree species in 4 genera of Buxus family. It is an evergreen shrub or small tree with light yellow wood, tough texture, fine texture, moderate hardness, no brown eyes, long growth period, and no aniseed.

Boxwood grows very slowly and blooms in winter. When spring comes, it usually takes four to fifty years to grow to 3-5 meters in height and less than 15 centimeters in diameter. Therefore, there are sayings that "a thousand-year-old boxwood is difficult to grow" and "a thousand-year-old boxwood is difficult to make a beat" (a kind of beat in musical instruments). ) statement. In the old days, it was said that boxwood trees not only did not grow long in leap years, but actually shortened. Su Shi of the Song Dynasty: "As the saying goes, boxwood grows one inch a year and retreats three inches during leap years." Therefore, it is called "dwarfed by thousands of years".

Nanmu

The more famous varieties of nanmu can be There are three types: First, fragrant nan, the wood is slightly purple with a fragrance, and the texture is also very beautiful; second, golden nan, there are golden threads in the wood grain, which is the best kind of nan wood. What is even more rare is that there are The second type of nanmu material forms natural landscape and figure patterns; the third is nanmu, which has softer wood and is often used to make furniture.

Phoebe belongs to the Lauraceae family and has many types. The ones commonly used in construction and furniture are mainly Aragon and Phoebe. The former is a large evergreen tree produced in Ya'an and Guan County, Sichuan; the latter is also known as golden nan and is produced in Zhejiang, Anhui, Jiangxi and southern Jiangsu. Nanmu has an elegant and well-proportioned color, small expansion and contraction deformation, is easy to process, and is resistant to decay. It is the best kind of soft wood.

Basswood

The white wood part of basswood is usually quite large and milky white, gradually incorporating light to brownish-red heartwood, sometimes with darker stripes. This wood has a fine, even texture with vague straight grains.

Basswood is well machined and easy to work with hand tools, making it an excellent carving material. The fixing performance of nails, screws and glue is still good. A good smooth surface can be obtained by sanding, staining and polishing. It dries fairly quickly, has little deformation, and has a low degree of aging. The shrinkage rate is quite large when drying, but the dimensional stability is good.

Basswood is light in weight, soft in texture, and relatively low in strength. It is a type of wood with poor resistance to steam bending. Resistant to rot, white wood is easily eaten by common furniture beetles. Penetrating antiseptic treatment.

Dark wood

Among the Chinese folk, dark wood is carbonized wood. Shu people call it ebony, and Westerners call it "Oriental sacred wood".

The formation of dark wood has a long history. According to available data, in ancient times, some of the centuries-old precious ancient trees in virgin forests were destroyed due to sudden major geographical and meteorological changes (such as earthquakes, flash floods, lightning strikes, typhoons, etc.). Buried deep under the ancient river beds and silt of rivers and lakes, some were buried in dark, anoxic strata for thousands or even tens of thousands of years. They have experienced rapid erosion, crushing by mud and rocks, and pecks by fish. Crabs live there in various shapes and postures. After thousands of years of natural abrasion, sombre wood combines the elegance of wood and the charm of stone. Its texture is solid and thick, its color is dark and luxurious, its cross section is smooth and delicate, and its wood is oily, resistant to moisture, has fragrance, and is immortal and not afraid of insects. , completely natural. Ancient books record that individual tree species also have medicinal value. It combines the characteristics of "thin, transparent, leaky, and wrinkled" and deserves the reputation of "Oriental Sacred Tree" and "Plant Mummy".

Sunken wood has been regarded as a valuable wood since ancient times, a rare thing and a symbol of nobility and status. There is a folk proverb in our country that "even if you have a box of jewelry, it is not as good as a piece of ebony" and "a thousand taels of gold will be sent to the underworld in exchange for ebony to offer sacrifices to the gods." In ancient times, dignitaries and literati regarded dark wood furniture and artworks carved from dark wood as family heirlooms, house treasures, and things to ward off evil spirits. Throughout the ages, especially during the Ming and Qing dynasties, gloomy wood has become the first choice material for emperors of all generations to build palaces and make coffins. The emperors of the Qing Dynasty listed it as a material exclusively for the royal family and could not be used privately by the people, making dark wood even more scarce. Yuan Shikai, the great thief of the Republic of China, went against the trend of history and died soon after his "emperor's dream". However, in order to show that he had once been an emperor, his family spent a lot of time and money to find gloomy wood and build a coffin for him. Although this is a historical joke, it also shows that gloomy wood is expensive and hard to find.

Strictly speaking, dark wood has gone beyond the scope of wood, and should be classified as a "treasure". This is because the "Treasure Garden" of the Palace Museum collects ingenious works of art carved from dark wood, which shows that their preciousness is far beyond what ordinary wood can achieve. In terms of texture, cultural value and appreciation prospects, dark wood furniture and artworks can be said to be unparalleled, even surpassing the precious rosewood.

Since ebony is a non-renewable resource and its development volume is becoming less and less, some natural-shaped ebony artworks are of great collection value.

Striped ebony

Striped ebony, also known as grained ebony, is striped ebony as the name suggests. The "Redwood" national standard separates striped ebony from ebony and becomes an independent category. Striped ebony and ebony both belong to the Diospyros genus of the Ebenaceae family. The difference between the two lies in the wood color: the heartwood of ebony is pitch black, while the heartwood of striped ebony is black or chestnut brown, with occasional Has light stripes. Persimmon tree (Diospyros), the difference between the two lies in the wood color: the heartwood of ebony wood is dark black, while the heartwood of striped ebony wood is black or chestnut brown with light stripes in between. Striped ebony was called wood, wenmu, and ebony wood in ancient times. Cui Bao of the Jin Dynasty's "Ancient and Modern Notes" said: "The wood comes from Linyi, Jiaozhou. It is black in color and has inscriptions, and it is also called Wenmu." Ji He of the Jin Dynasty "Southern Grass and Trees" "Zhuang": "The Wenmu tree is seven or eight feet high, and its color is black, like a buffalo horn. It is used as a riding whip, and it is found in the south of Japan." According to ancient records: "Uwen" comes to the ship, and the Uwen is rotten. In Japan, ebony and striped ebony are called ebony. According to Sudo Akira's "Nanyang Wood", striped ebony has black heartwood with gray or reddish-brown stripes.

Development Prospects of the Timber Industry

In the future economic integration process around the world, China will play a greater influence. Due to the high quality of China's labor force and its cheap labor price, China will become the center of the world's processing industry. The wood industry, such as plywood and furniture manufacturing, is mostly labor-intensive, with mostly small and medium-sized enterprises, which can absorb a large amount of labor and produce export products with obvious price advantages.

In the next period of time, China's wood processing industry will continue to maintain a high growth rate and move forward. In this process, there will be an increase in total production, but a more substantial change will be the shift from a large wood industry country to To strengthen the country in the timber industry.
