Method and device for remaining breeding of phyllostachys praecox

Abstract

The invention belongs to the technical field of agricultural planting, and particularly discloses a method and a device for remaining breeding of phyllostachys praecox. The method comprises the following steps: step 1, carrying out remaining breeding on new bamboos at the remote ends of mother bamboos in a young forest stage: (1) carrying out remaining breeding on 1-2 plants of robust bamboo shoots without diseases or pests of each plant of the mother bamboos for cultivating now bamboos, and (2) gradually increasing the remaining breeding quantity of the new bamboos from the second year to theforth year year by year; and step 2, carrying out remaining breeding in a forest forming stage: (3) carrying out remaining breeding on 150-200 new bamboos in each mu filed every year, keeping the number of standing bamboos to be 600-800 and maintaining uniform distribution, and (4) from the sixth year, cutting old bamboos with the age of five years or above from August to September every year, and keeping the cutting amount to be the same as the amount of the remaining breeding of new bamboos of the current year, so that the age structure of the bamboo forest is that the bamboos with the ageof one, two or three years account for 25%, the bamboos with the age of four years account for 20%, and the bamboos with the age of five years account for 5%. Through the adoption of the method, highyield and stable yield of the phyllostachys praecox can be realized.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method and a device for cultivating Phyllostachys praecox. Background technique [0002] Thunder bamboo is an excellent edible bamboo shoot that shoots first in spring. It has a thin shell and thick flesh, delicious taste, and high nutritional value, so it is very popular among people. [0003] In order to improve the economic benefits of bamboo shoots, early-emergence mulching cultivation techniques are generally implemented in production. Due to the high yield and good price of early shoots, the production focuses on harvesting bamboo shoots and neglecting retention, resulting in unreasonable bamboo density and bamboo age structure of mother bamboo. There are few shoots of female bamboo, and the average quality of single shoots decreases. With the increase of the cultivation period of Phyllostachys praecox forest, the output of Phyllostachys praecox is decreasin...
