A method of retaining bamboo to improve the production of bamboo shoots in traditional Mazhu forest

Abstract

The invention discloses a bamboo reservation and forest management method for raising the bamboo shoot yield of a traditional dendrocalamus latiflorus forest. The method comprises the steps of removing weeds and shrubs in the forest, stacking and burning the weeds and the shrubs, and then spreading ash into bamboo clusters in combination with soil loosening from December of the first year to January of the second year; from December of each year to March of the following year, cutting off all old bamboos at the age over two years old, reserving 3-6 annual / biennial raw bamboos per cluster by means of a geometric figure bamboo reserving method, applying fertilizer three times a year, applying base fertilizer for the first time in the middle and last ten days of March, and conducting topdressing twice in the initial stage and middle stage of emergence of the bamboo shoots, namely the period from June to August; cutting the bamboo shoots when the bamboo shoots grow to 20-45 cm out of the soil; picking and cutting the bamboo shoots used for processing when one green node of each bamboo shoot used for processing is exposed; selecting second-crop bamboo shoots for bamboo shoot conservation by means of the geometric figure method, and carrying out bagging cultivation on the conserved bamboo shoots; from December of each year to March of the following year, hacking down redundant old bamboos at the age over two years. The bamboo reservation and forest management method is scientific, reasonable, simple and feasible, the bamboo shoot yield is raised by 35% or above every year from the second year, the yield tends to be stable in the third year, the bamboo shoot yield per mu is 2,000-2,300 kg, and the economic benefit, the social benefit and the ecological benefit are great.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and relates to a bamboo forest management method for increasing the output of bamboo shoots in a traditional hemp bamboo forest. Background technique [0002] Ma bamboo (Dendrocalamus latiflous Munro), also known as "sweet bamboo", "Daye black bamboo" and "Badu shoot", its underground stems grow in clusters, belonging to the Gramineae family of clumping bamboos, and the genus Munro. This bamboo species has wide adaptability, easy cultivation, fast growth and early maturity, and has good functions of revetment, embankment, wind protection and soil protection, greening and beautification. Bamboo shoots are delicious, sweet and nutritious. Planting hemp bamboo requires less investment, quick results, high income, and remarkable economic, ecological and social benefits. [0003] At present, during the operation of hemp bamboo forests, bamboo stalks tend to be densely clustered and bamboo ...

AI Technical Summary

Problems solved by technology

[0003] At present, during the management of hemp bamboo forests, bamboo stalks tend to be densely clustered and bamboo roots overlap and concentrate, which has obvious restrictions on the efficiency of bamboo plants to receive and use sunlight and the absorption of nutrients. The annual increase will also cause the loss of soil fertilizer, and the bamboo stump and bamboo roots will be exposed, which will easily lead to the decline of bamboo bushes, reduce the yield of bamboo shoots and affect the quality of bamboo shoots.
