I. Bamboo Forest Structure
The establishment of a reasonable bamboo forest structure is the basis for the implementation of bamboo shoots and bamboo forests. The general requirements are: medium density, medium diameter, and light age. The amount of standing bamboo is appropriate to 140-180 plants per acre, and the density of the bamboo trees on bamboo slopes and bamboo groves on sunny slopes can be appropriately larger. Standing bamboo should not be too thick or too fine, and the diameter should be 30-33 cm.
Second, fertilization
1. time
Fertilization is usually carried out in the bamboo shoots from the 9th to the 10th of the month of the spring-growth period and the 2nd month of the green sprouting period of the spring bamboo shoots.
2. Fertilizer amount
According to the condition of bamboo forest and the yield index, fertilizer can be used for chemical fertilizers and organic fertilizers. Generally, 2000 kg of fertilizer is used per mu per year.
3. Fertilization method
1 furrows, ditch along the horizontal line, depth 15 to 20 cm, after the fertilization after the cover is solid, to reduce the loss; 2 plants, in the direction of the bamboo uphill 30 cm-shaped groove, about 15 cm deep, after the fertilization after the cover practical ; 3 facilities, mainly used for steep slope bamboo forest, close to the bamboo slope in the bamboo slope digging hole, into the organic fertilizer, soil compaction.
Third, bamboo, bamboo shoot management
Strengthening the management of bamboo shoots and bamboos is the key to increasing the output of bamboo and bamboo shoots. Quantitative and regular placement of bamboo shoots and bamboo shoots should be implemented. Quantitative is to select bamboo shoots according to the bamboo structure (number of 1 to 2 in young plants), generally 60 to 70 strains per acre is appropriate; timing is to select bamboo shoots of appropriate diameter in the middle and late period of bamboo forest bamboo shoot excavation; The selected long bamboo shoots are evenly distributed in the forest.
1. Digging bamboo shoots
Dig up early bamboo shoots. A bamboo whip often has many shoots, which can be differentiated into several bamboo shoots of different sizes. The bamboo shoots that were unearthed at the earliest stage are dug in time to provide opportunities for the next bamboo shoot to grow on the ground. On the other hand, early bamboo shoots have a higher market price. And suitable for making water shoots canned, high economic returns.
Dig for bamboo shoots at any time in appropriate quantities. It is limited to digging bamboo shoots in December to 10 days before the Spring Festival. Winter bamboo shoots weighing less than 0.25 kg should not be dug. Do not injure small winter bamboo shoots and whip buds when digging, and timely cover soil. Dig live bamboo shoots in time to ensure that bamboo shoots are fresh and free from pests and diseases.
Dig whole bamboo shoots. Under the premise of not damaging the whip, bamboo shoots will be completely excavated. This is an important measure to increase the yield and quality of bamboo shoots.
2. Bamboo
Reasonable bamboo cutting is a means to maintain the reasonable structure of bamboo forest. The number of ploughing bamboos should not exceed the amount of growth throughout the year. Generally, 20 to 30 arable bamboos per mu are harvested per year. The culling bamboos are bamboo culms, bamboo culms and bamboo trails that are older than 6 years old and less than 6 years old. The time should be measured in winter. . There are two types of felling methods, one is the flat rake method, which is cutting near the ground cuttings; the other is bringing the rake method, that is, with the entire bamboo rake or half bamboo rake cutting.
IV. Bamboo Forest Management
Recover. The best season for the restoration is the summer of the year when the bamboo was sent. A bamboo rim with a slope of less than 25 degrees implements a belt rim, and removes the “three heads†namely bamboo head, chaibu head and stone. It is about 30 centimeters deep.
level off hilltops. Every year during the rainy season, the young weed shrubs in the bamboo forest are tripped over, and evenly spread over the woodland. The term decomposes and rots, providing nutrients for the growth of bamboo whip.
