Where do bamboo shoots grow?

Question 1: Where do bamboo shoots usually grow? Bamboo is the general name of the Gramineae plant Zhuzhisubfamily, which is distributed in subtropical areas, also known as bamboo or bamboo. Some are as low as grass, and some are as tall as trees. It usually grows by creeping rhizomes underground. It can also be propagated by flowering and seed setting. It is a perennial plant. Some kinds of bamboo shoots are edible. There are about 150 genera and 1225 species in the world. Bamboo is mainly distributed in tropical, subtropical and warm temperate regions between 46 degrees north latitude and 47 degrees south latitude. The native bamboo species of the Fourth Ice Age can be found on all continents except Europe.

Question 2: How to judge where bamboo shoots grow? Looking for winter bamboo shoots, looking for green bamboo leaves on Zhushan Mountain and looking for fresh water that can be stored on Zhushan Plain are more suitable for the growth of bamboo shoots. If you look for bamboo shoots, they will grow out of the ground, so jump there!

Question 3: Where do bamboo shoots grow? There are several kinds of bamboo shoots with nutritional value. They are sweet, slightly cold and non-toxic, and have health-preserving effects such as clearing away heat and resolving phlegm, benefiting diaphragm and stomach, quenching thirst and benefiting qi. Boiling fresh bamboo shoots and crucian carp into soup is not only delicious, but also has the effect of appetizing and clearing away diarrhea. It is an auxiliary treatment for children with measles, rubella and chickenpox fever, and also has the effect of clearing heat and diuresis for patients with fever, dry mouth and unfavorable urination. Cooking white rice porridge with fresh bamboo shoots can treat chronic diarrhea and dysentery. Boiling bamboo shoots with calamus and winter melon peel to drink soup can obviously eliminate edema and ascites caused by nephritis, heart disease, liver disease and advanced schistosomiasis. Barbecued chicken with bamboo shoots is a good tonic in spring and summer. Modern scientific analysis proves that the nutritional value of bamboo shoots is quite high. Take winter bamboo shoots as an example. It contains about 4. 1g of protein, 0. 1g of fat, 5.7g of sugar, 22mg of calcium, 56mg of phosphorus, 0. 1mg of iron, and also contains carotene and vitamins. Protein composition of bamboo shoots is good, including lysine, tryptophan, threonine and phenylalanine, glutamic acid, which plays an important role in protein metabolism, and cystine, which maintains protein configuration. In addition, bamboo shoots are low in fat, sugar and fiber. Eating bamboo shoots can not only promote intestinal peristalsis, help digestion, promote digestion, and prevent constipation, but also be a good weight loss product for obese people. According to the "Medical and Health News" report, bamboo shoots are crisp, tender and delicious, and rich in nutrition. They are rich in cellulose, vitamins, fat and sugar, and have the functions of quenching thirst, diuresis, resolving phlegm, losing weight and helping digestion. Simple obesity, diabetes and edema are all suitable for eating bamboo shoots. However, bamboo shoots are cold food, rich in crude fiber, and easy to make gastrointestinal peristalsis too fast, so people with gastric ulcer, duodenal ulcer and gastric bleeding should not eat bamboo shoots. At the same time, patients with cirrhosis should not eat bamboo shoots. It has been reported that patients with liver cirrhosis eat more bamboo shoots at a time, which leads to massive bleeding in the upper digestive tract and is sent to the hospital for rescue. In addition, people with urinary calculi should not eat bamboo shoots often, and oxalate is easy to combine with calcium in other foods to form insoluble calcium oxalate, thus aggravating the condition. In addition, due to the cold nature of bamboo shoots, which contain more crude fiber and insoluble calcium oxalate, patients with severe gastric ulcer, gastrorrhagia, nephritis, urinary calculi, liver cirrhosis and chronic enteritis should use it with caution. Because bamboo shoots contain more oxalic acid, it will affect the body's absorption of calcium. Children should not eat more when growing up, and those with urinary calculi should not eat more. Some people are allergic to bamboo shoots and should avoid eating them.

Question 4: When did bamboo shoots grow? Phyllostachys pubescens, Phyllostachys pubescens and other scattered bamboo species have deep underground stems, and bamboo whips and bamboo shoots are protected by soil layers, so they are not easy to suffer from freezing damage in winter, and the shoot emergence period is mainly in spring. The underground stems of Dendrocalamus latiflorus, Phyllostachys pubescens and other clustered bamboo species are shallow in the soil, and the shoots are often exposed on the soil surface, which is vulnerable to freezing injury in winter, and the shoot emergence period is mainly in summer and autumn. Bamboo is native to the tropics and subtropics, and prefers temperature to cold. It is mainly distributed in areas with annual rainfall of1000 ~ 2000 mm. The optimum temperature for bamboo growth is 16 ~ 17℃, below 30℃ in summer and around 4℃ in winter. The annual average temperature of Dendrocalamus latiflorus and Phyllostachys pubescens is 65438 08 ~ 20℃, and the average temperature in June is above 65438 0℃. Therefore, bamboo forests are flourishing in the south of China and scarce in the north. Bamboo needs deep, loose, fertile, moist soil with good drainage and ventilation, and the suitable soil pH value is 4.5 ~ 7.

The growth law of bamboo

First, the growth of bamboo shoots-young bamboo (rod growth) As mentioned above, in the growth stage of bamboo shoots in soil, cells constantly divide and differentiate through apical meristem, forming nodes, internodes, internodes, bamboo shoots, lateral buds and mesophyll. The number of nodes of the whole bamboo shoot (also the whole plant) has been fixed before being unearthed, and no new nodes will be added after being unearthed. The growth of bamboo shoots starts from the base. First, the bamboo shoots grow in the bamboo sheath, and then the meristem between layers divides and grows one by one, pushing the bamboo shoots to move upward, through the soil layer and grow out of the ground.

(1) bamboo shoots-young forest growth period: the time from bamboo shoots unearthed to young forest height growth stopped varies with bamboo species. Bamboo shoots grow in large quantities and for a long time. The early bamboo shoots were unearthed for about 60 days, and the late bamboo shoots were about 40 ~ 50 days. Small and medium-sized scattered bamboo, such as Phyllostachys pubescens, Phyllostachys pubescens, Bambusa bambusa, etc., has a small growth and takes a short time, generally 25-30 days. For bamboo species with late shoots, the growth period of bamboo shoots and young bamboos is shorter. According to the growth rate of a young forest for bamboo shoots, it can be divided into early stage, rising stage, vigorous stage and late stage.

1 prophase: it is the continuation of underground growth of bamboo shoots. Although the tip of the bamboo shoot has emerged, the bamboo shoot is still in the soil, with obvious lateral expansion and growth, small internode length, and the basal nodes take root one after another, and the height growth is very slow. Generally, the day length is only 1 ~ 2 cm.

Ascending period: the elongation and growth of internodes in the underground part of bamboo shoots basically stopped, and later became the base of bamboo poles. A large number of bamboo roots germinate and the roots gradually form. The internode growth activity of bamboo shoots moves from underground to aboveground, and the growth speed is gradually accelerated, and the growth amount is correspondingly increased, generally reaching 10 ~ 20cm per day.

3 heyday: it is the fastest growing period of bamboo shoots. While the bamboo roots continue to elongate and begin to develop lateral roots, the height growth of bamboo shoots is rapid and stable, rising in a straight line. Growth peak 1 day and night length can reach about1m. Bamboo shoots began to fall off at the base, and the upper branches began to spread, and the high growth rate changed from fast to slow. Bamboo shoots gradually transition to the young bamboo stage. In addition to the tip covered with bamboo shoots, under the action of light, chlorophyll is produced between the middle and lower nodes, which turns into green "bamboo green" for photosynthesis, providing some nutrients for the growth of bamboo shoot seedlings.

At the end of the fourth stage, the young bamboo shoots bent and the branches extended rapidly, but the high growth rate decreased obviously and finally stopped. After all the bamboo shoots are peeled off and the branches grow, all the bamboo leaves spread out to form a new bamboo.

Second, the growth law of young bamboo shoots: during the growth process, the elongation activities of all bamboo shoot internodes are not carried out at the same time or at the same speed, but from the base, from bottom to top, according to the law of slow, fast and slow, and a certain number of elongation internodes constitute the extension of high growth of bamboo shoots. The extension of bamboo shoots is long, and the number of nodes is as high as 14 ~ 15. Small and medium-sized scattered bamboo shoots have shorter extension and fewer nodes, generally 6 ~ 10.

Intermediate meristem realizes internode growth through cell differentiation, elongation and aging. Just like the growth of a young bamboo shoot, the elongation of each node in the extension section can also be divided into initial stage, ascending stage, peak stage and final stage. When the lower internode of this node is at the end of growth, the middle internode of this node is at the peak of growth, while the upper internode is at the rising stage and the initial stage. The elongation of the lower internodes gradually stops, the elongation of the upper internodes accelerates step by step, and the extension section moves forward step by step from bottom to top, which is the concrete manifestation of the growth of bamboo shoots-young internodes.

3. Changes of water content during the growth of bamboo shoots and young bamboos: Newly unearthed bamboo shoots are tender and have extremely high water content. With the increase of time and height after excavation, bamboo shoots age and the water content of bamboo shoots decreases obviously. In the same bamboo shoot, the lower part of the extension zone moves forward from bottom to top, and the base is more aging, which includes ... & gt

Question 5: How to quickly see where the winter bamboo shoots grow? Harvesting technology

1, technical score

(1) Dig holes to dig winter bamboo shoots

Five.

New picture

From mid-June 10, a detailed observation was made around the pregnant bamboo shoots. Generally, the soil on the surface is loose or cracked, and there may be winter bamboo shoots underground where the feet feel soft, so dig a hole with a hoe.

(2) dig winter bamboo shoots along the whip.

Firstly, the pregnant bamboo shoots with dense branches and dark green leaves are selected, and the beating direction is judged to be consistent or close from the direction guided by the first branch. First, you can dig shallow near the base to find a strong yellow or brown whip, and then dig along the whip to find winter bamboo shoots for harvesting and utilization.

(3) dig bamboo shoots comprehensively

Combined with soil loosening and fertilization in winter, the bamboo forest should be cultivated and reclaimed, and the middle should be turned about 20 cm. Don't turn over large pieces of soil to prevent the whip root from being lost and broken. If there are winter bamboo shoots when digging, you can dig them out at one time.

Local experience of harvesting winter bamboo shoots

winter bamboo shoots

(1) "Look at the bamboo leaves of Phyllostachys pubescens, and then dig the whip. When they touch the bud tips, the tender whip will chase them, and the old whip will pull them forward." /kloc-At the end of 0/2 (Lunar New Year), look for bamboo whips with black leaves and yellow leaves around New Year's bamboo. When you dig a bud with a pointed bamboo shoot, if you touch the tender whip and get it back, the old whip will dig forward and there will be winter bamboo shoots.

(2) When the old bamboo whip is chased to the end, there is often a new bamboo whip, starting from the starting point of the whip and reaching the 18 section (generally about 80 cm, there are winter bamboo shoots.

(3) "If you can't find the whip, it means that when you can't find the bamboo whip, you can chase the bamboo whip in the spring bamboo cave. Generally, there are winter bamboo shoots near the bamboo shoots in previous years.

(4) "Low branches, thick bamboo branches and more forked bamboo shoots" refers to the large bamboo with low branches at the bottom and thick bamboo branches, which often produces more bamboo shoots.

(5) "Whip down the mountain, whip long, long section, less bamboo shoots, whip up the mountain, whip short, short section, more bamboo shoots.

Question 6: Where do winter bamboo shoots usually grow? Winter bamboo shoots grow in the soil. With the growth of winter bamboo shoots, the soil surface will be broken, commonly known as bamboo shoots cannon, which is an important information for digging winter bamboo shoots! Its tail has not been unearthed, or green has been unearthed, but its body has not been unearthed. They are all winter bamboo shoots. Winter bamboo shoots are egg-yellow, the shell is orange, the meat is white without knots and few roots. Generally, after the Spring Festival, winter bamboo shoots become bamboo shoots. The shells of bamboo shoots are brown, hairy on the shells and pimples on the meat! Unearthed at least 2 cm! Bamboo shoots before the Spring Festival are all winter bamboo shoots, and those after the Spring Festival are all spring bamboo shoots!

Question 7: Where are the winter bamboo shoots? Sorry, I really don't understand this!

Question 8: Where are bamboo shoots mainly distributed? Basically, there are bamboo shoots where there are mountains, but they are called differently everywhere.

Question 9: Where are the roots of bamboo shoots? Bamboo shoots are the parts of bamboo roots that grow out of the ground after germination. Bamboo shoots have no branches and leaves, and they are not as hard as the outside of bamboo. When shoots grow on the branches of bamboo shoots and the shoots become branches, bamboo shoots become bamboo.

Question 10: Where do bamboo shoots usually grow? Phyllostachys pubescens is mainly distributed in Yibin, Hunan, Jiangxi, Fujian, Zhejiang and other places. The bamboo quality of Phyllostachys pubescens is the best in Hunan, followed by Jiangxi and Fujian.

Bamboo shoots are generally unearthed in the middle and late March, and the principle of digging bamboo shoots in the early stage, selecting bamboo shoots in the middle stage and leaving mother bamboo in the later stage should be followed. Early bamboo shoots have high prices and good economic benefits. Digging out early bamboo shoots in time can also reduce the nutrient consumption of Phyllostachys pubescens, promote the germination of dormant but meristematic bamboo shoots, and achieve the goal of more bamboo shoots and high yield. The results show that the selection and retention of mother bamboo at different shoot emergence stages have great influence on bamboo shoot yield. In Yixing, Jiangsu, the yield of Phyllostachys pubescens in Grain Rain was 30.7% higher than that from Qingming to Grain Rain, and 373% higher than that from Qingming.

Bamboo shoots of Phyllostachys pubescens begin to germinate in July and August in autumn, when they are very small and have no edible value. In winter, bamboo shoots will grow into bamboo shoots, called winter bamboo shoots, which can be dug and eaten.
