Cutting bamboo in winter is conducive to the vigorous growth of bamboo forests, how to cut bamboo?

Generally bamboo.

After the bamboo shoots grow, they can grow into bamboos in just two months. If you don't use old bamboo, the bamboo that grows in the year can be cut down, using the agricultural proverb "cut winter but not spring". According to the experience of various places, the bamboo used to make bamboo products must be cut in winter, and the time is from the beginning of winter to before the beginning of spring of the following year.

On the one hand, the reason why the bamboo is cut around September is that the climate is suitable at this time, and the transpiration of the bamboo.

Small, the loss of nutrients after cutting is relatively small, and it does not have much impact on the new bamboo shoots in the next year.

<> bamboo forest, as long as it is properly managed, moso bamboo.

Not only are there many bamboo shoots, but also the individual is large, and the size of the year is not obvious, which can basically achieve stable and bumper yields. Among them, the scientific management of bamboo forest not only refers to winter fertilization, but also includes clear irrigation, "go to the three heads", reclamation, hook and other fertilization before the stones and sundries in the bamboo bushes to pick up all the stones, sundries, pay attention not to hurt the bamboo shoots, and then remove the weeds within 40 to 50 cm around the bamboo bushes, above the bamboo bushes, 30 to 40 cm away from the bamboo fence, with a hoe.

Dig a semicircular trench 10 to 15 cm deep.

In order to increase the number of shoot bud differentiation, improve the quality of shoot bud differentiation, and make the shoot buds full, germination fertilizer should be applied in time, and the fertilizer is mainly fast-acting fertilizer, and urea is sprinkled per mu.

The average eyebrow circumference (DBH) of a 50 kg bamboo forest should be larger; The size of the bamboo in the bamboo forest should be neat; Leaf area index of bamboo forest.

(Leaf area index refers to the ratio of the total area of bamboo leaves in a bamboo forest to its forest area). Generally, the bamboo shoots are used in May and June in the year to facilitate the whipping; In the small year, it is beneficial to change leaves in May and June, so that the new branches and new leaves are dense and green, enhance the assimilation efficiency of the whole stand, and accumulate a large amount of dry matter. In the small year, in August and September, it is beneficial to the differentiation of bamboo shoots, and the hook tips should be carried out in winter, and the bamboo poles are hooked off with a long-handled knife above 15 branches, and the bamboo tips can be made into brooms and other processing and utilization. In winter, the bamboo enters dormancy, at this time, the pile will not cause injury, and the bamboo material is good and not easy to be eaten by insects.

First of all, it is necessary to determine the degree of bamboo, under normal circumstances, the average circumference diameter is less than 10 cm, and 700-800 plants should be left per mu; about 15 cm, 500-600 plants per mu should be left; 20-30 cm, about 400 plants per mu should be left; For more than 30 cm, 250-300 plants per mu should be left. Secondly, the principle of "cutting the old and leaving the young, cutting the small and leaving the large, cutting the dense and leaving the thin, and cutting the weak and leaving the strong" should be followed.

Three-year bamboo should be cut down all, two-year-old bamboo should be cut off, one-year bamboo can not be felled, in addition to the number of cut bamboo should be paid attention to, after cutting bamboo, each mu of bamboo should be guaranteed to be more than 2,000 plants.

Determine the degree of bamboo, which is based on canopy density, to ensure that the bamboo forest has no skylight, and can make branches and leaves; Photosynthesis is carried out to the fullest. Generally, the average circumference diameter is less than 10 cm, and 700 800 plants should be left per mu; about 15 cm, 500-600 plants per mu should be left; 20 30 cm, each by should be left about 400 plants; For more than 30 cm, 250-300 plants per mu should be left. The main cutting objects should be mastered when harvesting: the principle of "cutting the old and leaving the young, cutting down and leaving the large, cutting the dense and leaving the thin, and cutting the weak and leaving the strong".

Harvesting is advisable for 4-6-year-old ones. For those who are more than 7 years old, the growth potential decreases, the elasticity of the bamboo decreases, the brittleness, and the resistance to the bamboo and tensile strength decreases, so it should be cut off; At the same time, it is also necessary to cut down the pressed bamboo, seriously diseased and insect bamboo, and do not cut off the whip bamboo. When cutting bamboo, the cultivator gang advises not to hurt the bamboo whip and standing bamboo.

After cutting, the bamboo stalk should be split, pierced through the bamboo, and a little lime should be put to make it decay quickly, so as to facilitate the whipping of bamboo shoots and ensure the vigorous growth of the bamboo forest.

In winter, the time should be after the beginning of winter in the current year and before the beginning of spring in the following year. In this way, the quality of the bamboo is quite good and does not affect the growth of the next generation of bamboo.

The quality of bamboo is also related to the season of cutting bamboo:

1.Spring, the wind and sunshine are beautiful, and the spring flowers are blooming, which is the season for the mass breeding of various pests. At this time, the bamboo contains high levels of nutrients such as starch, soluble sugar, fat, and water.

If the bamboo is cut at this time, the borer likes to lay eggs in the newly cut bamboo. At the same time, when the bamboo is cut in spring, a large amount of bamboo dissolution is lost, which makes the bamboo tissue loose, which also opens the door for the invasion of borers. Therefore, the insect rate of bamboo cut in spring is as high as 40-50.

In addition, a large number of spring bamboo shoots are cut down, which also seriously affects the growth of spring bamboo shoots.

2.In summer, the sun is scorching, and the heat is unbearable. The bamboo tissue will also become denser and the texture will be harder. This makes it difficult for borers to invade. It stands to reason that cutting bamboo is the most ideal at this time, but summer bamboo is difficult to process, so from the overall consideration, it is not good to cut bamboo in summer.

3.Autumn, the sky is refreshing, the weather is pleasant, and it is a good time for bamboo to grow. At this time, the bamboo is rich in nutrients, and the texture is not as hard as in summer, which creates favorable conditions for the invasion and survival of borers.

According to the test, the probability of being eaten by moths is as high as about 26 for bamboo cut in autumn, and it seems that cutting bamboo in autumn is not ideal.

4.In the middle of winter, the weather is dry and cold, and the pests have entered hibernation, which is the best season for cutting bamboo. At this time, the physiological activity of bamboo is rapidly weakened, nutrients and water are concentrated in the roots, the nutrient content of bamboo plants is very low, the water content is also very small, and the bamboo tissue structure is tight, the texture is tough, the strength is also large, and the moth is difficult to invade.

Therefore, the bamboo cut in winter is less than 5 infested by moths, so there is an agricultural proverb "cut winter not spring". According to the experience of various places, the bamboo used to make bamboo products must be cut in winter, and the time is from the beginning of winter of the current year to the beginning of spring of the following year.

. What kind of bamboo is cut on the first floor? Most of the bamboo is cut in late November, which can leave green and conducive to growth in the next year.

There is also a saying that the yin is cut in summer and the yang is cut in winter (mainly depending on what is used for it) Yangshan refers to the side of the mountain facing the east, and the yin mountain is the side pointing west.

How to cultivate bamboo forests? Bamboo forest management technology!

Moso bamboo has the characteristics of less flowering, fast reproduction, early maturity, high yield, wide use and good efficiency.

So how to cultivate bamboo forests? Today, I will share with you the bamboo forest management technology, let's take a look!

How to cultivate bamboo forests?

1. Selection of afforestation land: It is better to have sufficient sunlight, gentle slope, deep soil layer and sandy soil in early spring.

2. Land preparation: to use strip land preparation, generally 40 plants per mu, the hole is 100cm long, 600cm wide, and 40cm deep, and the bottom of the hole should be dug flat.

3. Selection of bamboo species: 1-2-year-old bamboo forest, with a thickness of 8-15cm in chest circumference, a mother plant with strong branches and low branches is better, and more than 20kg is carried at the same time.

Bamboo forest management technology!

1) fertilization and soil cultivation;

2) Cutting grass and loosening soil;

3) Harvest old bamboo, in order to reach more than 70% of 1-3 years of mother bamboo;

4) Water management;

5) Measures such as the transformation of declining forests.
