High-altitude layering propagation method for sympodial bamboo

Abstract

The invention belongs to the field of plant cultivation and relates to a high-altitude layering propagation method for sympodial bamboo. The method comprises the following steps of: breaking shoots of main culms, main branches and secondary branches, keeping main culms or secondary branches which are 1-3 meters in height on the middle lower part, cutting growing bamboo branches which are 1-2 centimeters away from the main culms, main branches or secondary branches, and keeping bamboo bases; and covering every culm ring of the main culms, main branches or secondary branches with a plastic bottom-free barrel bag, tightening the lower side of each barrel bag, filling a root inducing substrate which comprises a culm bud and a branch bud, tightening the upper side of each barrel bag to form a cylindrical container, and keeping the root inducing substrate in each barrel bag wet. Due to the adoption of the method provided by the invention, the problems of low survival rate of bare-rooted bamboo seedlings, high cost and severely insufficient bamboo seedling supply during the development of the bamboo industry are solved; and moreover, the method is easy to operate, materials are readily available, the cost is low, and large-scale popularization and application to production are facilitated.

Description

technical field [0001] The invention belongs to the field of plant propagation, and relates to a propagation method of clustered bamboo, in particular to a high-altitude layering propagation method of clustered bamboo. Background technique [0002] Bamboo is widely used, has important ecological benefits and high economic value. Bamboo industry development is one of the most potential emerging industries in my country's forestry construction. Compared with scattered bamboo, clustered bamboo generally grows faster and has higher yield, so it is suitable for afforestation. At present, the commonly used propagation methods mainly include branching, burying stalks, burying knots, and cuttings of bamboo branches, etc., which have low seedling efficiency and high cost; all the seedlings cultivated are bare-rooted seedlings, and the survival rate of afforestation is low, especially after long-distance transportation. In the case of prolonged drought, the survival rate of afforest...

AI Technical Summary

Problems solved by technology

At present, the commonly used propagation methods mainly include branching, burying stalks, burying knots, and cuttings of bamboo branches, etc., which have low seedling efficiency and high cost; all the seedlings cultivated are bare-rooted seedlings, and the survival rate of afforestation is low, especially after long-distance transportation. In the case of prolonged drought, the survival rate of afforestation is lower

It often leads to no forest in afforestation, which not only increases the cost of afforestation, but also delays the time for afforestation

[0003] A few places also use the container method to cultivate bamboo container seedlings, but the cost is high and the transportation is inconvenient, resulting in high afforestation costs and slow afforestation speed, which is difficult to meet production needs, which greatly affects the promotion and use
