What is the flower language of bamboo _ the flower language of bamboo?

In Chinese traditional painting, there are landscape plants, which are often compared to people with high moral character and integrity, and are called one of the four gentlemen, namely bamboo. So, what is bamboo flower language? I'll tell you next.

Bamboo flower language, flexible and strong life, eternal youth, integrity and pride, modest personality, long and peaceful life, happiness and harmony, dignified behavior.

Bamboo: it shows integrity, although not strong, but it is tall and firm; Not afraid of cold and heat, it lasts forever. Bamboo, plum and pine are "three friends of the old cold", pine symbolizes evergreen, plum symbolizes purity and cleanliness, and bamboo is the embodiment of a gentleman and a gentleman among the "four gentlemen". Seven virtues of bamboo, bamboo is tall and unyielding; Means integrity. Although bamboo has bamboo joints, it does not stop; It's called endeavor. Bamboo is straight outside and hollow inside, like a valley; This is an empty idea. Bamboo can't blossom, face up; It's simple. Bamboo is detached, independent and indomitable; It's called the drow. Although bamboo is outstanding, it is not loose; This is a good team. Bamboo has been handed down from generation to generation, working hard and blaming others; This is called responsibility.

Morphological characteristics of bamboo leaves

Bamboo is a fast-growing herb. Its bamboo leaves are narrow and lanceolate, 7.5 ~ 16 cm long and 1 ~ 2 cm wide. Its top is tapered, its base is blunt, and its petiole is about 5 mm long. One side of the edge is smooth and the other side is rough with small serrations. Parallel veins, 6 ~ 8 pairs of secondary veins, small transverse veins are very significant; The leaves are dark green, hairless, the back is lighter, and the base is slightly hairy; Thin and brittle. The length of bamboo shoots is 10 ~ 30cm, and the number of green nodes of bamboo is generally between 10 ~ 15.

Zhu Zihua

Bamboo flower is a purple flower like the ear of rice. Every purple flower has three stamens and a pistil hidden in the flower. When the pollen of stamens falls on the stigma of pistil, seeds can be formed, and after reproduction, new bamboo can grow. After flowering, the stems and leaves of bamboo will turn yellow.

subterranean stem

The underground stem of bamboo, commonly known as bamboo whip, grows horizontally, with a little hollow in the middle, nodes, many and dense, and many fibrous roots and buds grow on the nodes. Some buds develop into bamboo shoots that drill out of the ground and grow into bamboos, while others do not grow out of the ground, but grow horizontally and develop into new underground stems. Therefore, bamboo grows in patches and forests. Young bamboo whips and bamboo shoots are edible. Bamboo propagated by seeds is difficult to grow thick, and it will take decades to grow to the original thickness of bamboo. Therefore, bamboo whips, that is, underground stems, are generally used for reproduction. It only takes 3-5 years to grow to the specified thickness.

Winter bamboo shoots and spring bamboo shoots

In autumn and winter, bamboo shoots have not yet grown out of the ground, so digging them out is called winter bamboo shoots; In spring, bamboo shoots grow on the ground and are called spring shoots. Winter bamboo shoots and spring bamboo shoots are common foods in China cooking. In spring, bamboo shoots wait for the spring rain in dry soil. If there is a soaking rain, bamboo shoots will grow out of the ground at a fast speed.

The growth environment and climate of bamboo

Most bamboos like warm and humid climate and are abundant in tropical, subtropical and temperate regions. Bamboo is one of the forest resources. There are more than 70 genera 1200 species of bamboo plants in the world, mainly distributed in tropical and subtropical regions, and a few bamboos are distributed in temperate and cold regions. Bamboo is a shallow-rooted plant, and there are a few evergreen bamboo species falling leaves in dry season, which requires high hydrothermal conditions and is very sensitive. The hydrothermal distribution on the earth's surface dominates the geographical distribution of bamboo. Southeast Asia is located in the tropics and south subtropics, influenced by the monsoon of the Pacific Ocean and the Indian Ocean, with abundant rainfall and stable heat. This is an ideal ecological environment for bamboo growth and the center of bamboo distribution in the world. At present, the bamboo forest area in the world is about 22 million hm2. The geographical distribution of bamboo in the world can be divided into three major bamboo areas, namely, Asia-Pacific bamboo area, American bamboo area and African bamboo area, and some scholars have listed them separately as introduction areas in Europe and North America.

land

Bamboo requires deep and fertile acid soil rich in organic matter and mineral elements. Because the underground stems of clustered bamboo and miscellaneous bamboo are shallow in the soil, bamboo shoots appear in summer and autumn. Hsinchu can't be completely lignified in that year and can't stand the cold and drought, so the growth in the north is generally limited, and their requirements for soil are higher than those of scattered bamboo.

moisture

Bamboo requires not only enough water, but also good drainage.

Selection of bamboo propagation methods

Many methods are used for propagation, such as branching, burying branches, whipping and sowing. Bamboo whips are very capable of sprouting. Cut off the bamboo whip before germination in early spring and plant it with bamboo poles so that new bamboo can grow in that summer. Seeds of bamboo after flowering can also be sown.

1, burying whip to raise seedlings

Suitable for scattered bamboo species and mixed bamboo species. The method is as follows: dig the strong whip, keep the root and bud of the whip, leave more root soil, cut the bamboo whip into 50-60 cm whip segments, lay them flat on the seedbed, cover the soil with a thickness of 5-8 cm, and keep the seedbed moist. The time to bury the whip should be one month before the bamboo shoots are unearthed in early spring. After burying the whip, pay attention to watering in dry days and draining in rainy days. Apply nitrogen fertilizer in time after emergence, such as urea, ammonium sulfate and decomposed human excrement and urine, and weed in time. As long as it is properly managed, 2-3 bamboo seedlings can grow after one year per whip for afforestation in the following spring.

2. Burying stems to raise seedlings

Suitable for clustered bamboo species. The method is as follows: select a 2-year-old robust bamboo pole, dig it up with or without stumps, leave a branch on each node of the bamboo pole, cut off the tip of the bamboo pole, cut or saw a gap in the middle of each node every 1 ~ 2 nodes, immerse the bamboo pole in clean water, and seal the incision with soil after the bamboo cavity is filled with water. The seedbed is furrowed horizontally, the bamboo pole is laid flat, the incision is upward, and then the seedbed is covered with soil for 5 ~ 10 cm to keep the seedbed moist. About 1 month, bamboo buds germinate and emerge one after another. After half a year to a year, you can dig out the bamboo poles and cut them into bamboo seedlings for afforestation. The best time to raise seedlings by burying stems is about 1 month before bamboo germination.

3, burying nodes to raise seedlings

This method is also suitable for clustered bamboo species, especially those with latent buds at the base of lateral branches, such as bamboo pole, green bamboo, big-headed bamboo and hanging bamboo. The method is: the bamboo pole is sawed into one section or every two sections, and then buried in the seedbed, covered with soil and moisturized, and its management requirements are the same as those of burying the pole to raise seedlings.

4, lateral branch seedling raising

This method is also suitable for clustered bamboo species. The method is: take down the secondary branches of the lateral branches from the bamboo nodes over 2 years old, cut off the redundant branches and bamboo leaves, and keep 5 ~ 8 nodes to protect the buds at the base. Insert the lateral branches into the seedbed to expose the branches and leaves above. Seedbeds should be shaded and watered frequently. After 1 ~ 2 weeks, the secondary branches grow roots and new buds on the branches and gradually develop into independent bamboo plants. Generally, lateral branch cutting is the best in the most vigorous period of bamboo growth. After one year's cultivation, the lateral branch seedlings can be tillered into bamboo bushes and then planted.

environmental requirement

Bamboo blooms through any mutation of asexual reproduction. Bamboo should be planted in sunny and humid environment. Bamboo grows fast, has a large amount of growth, requires high water and fertilizer, has sufficient moisture and humidity, and has good drainage. The soil is required to be deep and fertile, and acidic soil rich in organic matter and mineral elements. Common garden plants are Phyllostachys pubescens, Pterocarya stenoptera, Phyllostachys pubescens, Phyllostachys pubescens, Phyllostachys pubescens and so on.

disease control

The pests of potted bamboo are mainly aphids and scale insects, and 80% dichlorvos emulsion or 40% dimethoate emulsion 1000 times can be sprayed. The main diseases are sooty blotch, witches' broom and so on. Management should be strengthened and diseased plants should be pruned in time.

Prevention and control of common diseases of bamboo species;

1. Tending management and reasonable logging should be strengthened. After the disease occurs, dig ditches around the dead bamboo shoots in time to isolate the diseased bamboo and prevent it from spreading and expanding the kit.

2, bamboo shoots rot:

1 Don't choose vegetables, pine trees and fir trees as nursery grounds; the base fertilizer should be decomposed. Two-year-old robust bamboo seedling.

The rotten shoots and tips should be cut off from the base immediately.

Spraying 50 times of aqueous solution or potassium permanganate after emergence or early onset, and spraying 1 time every 10 day until the bamboo seedlings grow vigorously.

3, bamboo seedling blight:

1 Don't choose vegetables, pine trees and fir trees as nurseries.

2. Apply Su Hua 9 1 1 or Sunong 640 1 at a dosage of 3.4kg/hm2, mix with fine soil evenly according to the ratio of 1: 200 ~ 300, and cover the seeds on the seedbed, or use 0.3 ~ 0.5 kg/hm2. After emergence, the disease began to spread on the bed surface. 0.2% ~ 0.3% of the seed weight can be used for seed dressing, or 0.2% of Sunong 640 1 or 0.5% of Dixon's first mixing 10 ~ 15 times of fine soil can be used for seed dressing and sowing.

4. The Bordeaux mixture of1∶100 ~150 can be sprayed for 2 ~ 3 times during the onset period of Phyllostachys pubescens seedling.

5, bamboo shoot wilt

1 Eliminate pathogens: combine bamboo cutting and hook shoot, cut off bamboo plants or bamboo shoots infected with dead shoot disease, and burn diseased bamboo shoots in time. Don't use dead bamboo branches as fences.

During the peak period from July to August, the investigation should be strengthened, and it was found that the branches and leaves of Hsinchu were yellow and brown spots appeared on the nodes of bamboo stems. Remove bamboo shoots in time at 1 ~ 2 nodes below the disease site to avoid the spread of the disease and the death of the whole plant.

3 Use 50% carbendazim wettable powder or 70% thiophanate-methyl wettable powder 1∶ 1000 times solution, or 1% bordeaux solution, and spray it every 15d when spreading leaves on Hsinchu.

Strict quarantine, do not transport the mother bamboo out of the ward.

6. Spraying 50% carbendazim wettable powder or 70% thiophanate-methyl wettable powder 1000 times solution or 1% bordeaux solution continuously for 2-3 times every 15d.

7. Bamboo witches' broom disease Strengthen the tending management of bamboo forests, cut down old bamboos and maintain proper density. And loosen the soil and apply fertilizer to promote the vigorous growth of bamboo forests. When developing new bamboo forest, the mother bamboo should choose disease-free bamboo forest. It should be removed as soon as possible at the early stage of the disease.

8, bamboo stem rust

1 Strengthening the management of bamboo forests and cutting them down rationally can also reduce the chances of diseases without making bamboo forests too dense.

2 Bamboo forests with mild illness should be cut down as soon as possible, and the diseased parts should be burned to avoid the spread of germs; Spraying 0.5 ~ 1 degree lime-sulfur mixture or aminobenzene sulfonic acid on the seriously ill bamboo forest, spraying 1 time every 7 days for 3 times in a row, has a good effect.

Spraying 1 degree pomegranate sulfur mixture or 100 ~ 150 times of diclofenac sodium in the bamboo forest during 36 ~ 10 months.

4 Spray 500 times solution of 25% wettable powder or 50% wettable powder 1000 times solution for 2 ~ 3 times every 10d or so.

9. Bamboo smut strengthens the management of bamboo forest, properly cuts it down, promotes the vigorous growth of bamboo forest, and reduces the incidence rate. If there are a few bamboo plants in the bamboo forest, it is best to cut off the diseased bamboo in time before the black powder flies away and burn the twigs with black powder to avoid spreading.

10, the prevention and control of bamboo coal diseases should focus on killing aphids, mosquitoes and crustaceans, such as using dimethoate to control aphids and nymphs of rare crustaceans, using turpentine mixture to control crustaceans, and using sulfur mixture to kill nymphs of old crustaceans. Proper felling can make the bamboo forest ventilated and transparent, which can greatly reduce the incidence rate.

1 1, bamboo witches' broom disease

1 bamboo scab mostly occurs on small bamboos that grow too densely. Appropriate thinning, reducing the density of bamboo forest, strengthening tending management, promoting the vigorous growth of bamboo forest and reducing the incidence rate. Cut off the diseased branches and burn them after the onset.

2 spray stone sulfur mixture.

12, bamboo nevus disease

1 Strengthening tending management and proper thinning and ventilation of bamboo forests can reduce the occurrence of diseases.

2. Spraying 1% Bordeaux solution can be used for bamboo forests with serious diseases over the years.
