Hardwood cutting seedling method of Edgeworthia chrysantha.

Abstract

The invention discloses a hardwood cutting seedling method of Edgeworthia chrysantha.. The method comprises the following steps that ramets of Edgeworthia chrysantha. mother trees are selected to serve as seedlings; the surfaces of the seedlings are disinfected and cleaned; the disinfected and cleaned seedlings are planted into seedling beds, Edgeworthia chrysantha. young seedlings are cultivated and grown up to Edgeworthia chrysantha. saplings in original cultivated land, and a nutritional agent is sprayed one time every three months during the growth period; the Edgeworthia chrysantha. saplings with a certain tree age are selected to serve as mother seedlings, living branches in grown and fruited Edgeworthia chrysantha. trees are selected to be cut off, so that cuttings are prepared, at least one shoot is reserved in each cutting, then the cuttings are subjected to cuttage on the mother seedlings for propagation, and the nutritional agent is sprayed one time every month during the propagation period; the mother seedlings and the cuttings are subjected to cultivation and management. By means of the method, the survival rate of the Edgeworthia chrysantha. saplings can be improved, the fruited saplings is good in growth vigor, good in quality and stable in production value, and the method greatly promotes the development of the Edgeworthia chrysantha. industry, and has obvious economic benefits, social benefits and cultural benefits.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation and planting, and in particular relates to a method for growing seedlings by cutting hard branches of A. japonicus. Background technique [0002] Edgeworthia chrysantha (Edgeworthia chrysantha.) is a plant of Thymelaeaceae and the genus Amethystaceae. It is a shrub about 0.7-1.5 meters high. The branchlets are thick and brown. They are often trifurcated branches. The young branches are often pubescent. The bast is extremely tough and the leaves are The scars are large, about 5 mm in diameter. Leaves withered before flowering, oblong, lanceolate to oblanceolate, apex mucronate, base cuneate or attenuate. Produced in Henan, Shaanxi and the provinces south of the Yangtze River Basin. Wild or cultivated. Stem bark fiber can be used as high-grade paper and artificial cotton raw materials. The whole plant can be used as medicine to relax tendons, relieve inflammation and relieve pain, treat...

Problems solved by technology

[0003] In recent years, my country has introduced artificial cultivation technology. Although this method can effectively solve the current situation of the shortage of fragrant fruit, it is found that the price of seedlings is extremely high during the introduction and cultivation process, and the survival rate is low. Large, it may become an ordinary Acacia tree, the problem of uneven aroma production rate and quality, which seriously affects the planting income of Acacia. Another way of reproduction is tissue culture. Propagation of Acacia through tissue culture has been achieved. Successful, but due to the difficulty of operation technology and harsh aseptic production conditions, this method has not yet been tested and promoted in production

[0004] As a precious tree species, the germplasm resources are extremely scarce, and a small amount of existing artificial cultivation not only has extremely low survival rate and aroma production rate, but also has poor stability, and the quality of the aroma is different.
