Problems solved by technology

The use of seeds for the breeding of willow willow seedlings has problems such as difficult collection of seeds, short storage time of seed vigor, large variation in the shape of the seedlings bred, uneven growth, and inability to fix excellent traits.
There is no report about the vegetative propagation of Willow chinensis at present, therefore, it is urgent to provide a method for improving the survival rate of vegetative reproduction of Willow chinensis

Embodiment 1

[0032] A method for improving the survival rate of asexual reproduction of Willow chinensis:

[0033] Step 1, seed selection: select the excellent variety of willow willow, one-year-old robust seedling trunks or branches on young trees, with a diameter of 0.5cm. The seedlings or branches are strong and free of diseases and insect pests, and the side buds are full.

[0034] Step 2, scion preparation: the seed strips are cut short to make scions, each scion is 3.0cm long, and only one leaf bud on the top is kept. The bottom of the scion is cut into a wedge shape with a wide outside and a narrow inside with a grafting knife. The length of the cut surface is about 1.5cm, and the cut surface is kept smooth to prevent damage to the cut surface, which will affect survival.

[0035] Step 3, rootstock extraction: select dry willow 1-year-old robust seedlings or branches on young trees as rootstocks, the rootstock length is 6.0cm, the thickness is determined according to the thickness o...

Embodiment 2

[0043] A method for improving the survival rate of asexual reproduction of Willow chinensis:

[0044] Step 1, seed selection: select the excellent 2-year-old strong seedling trunk of Willow chinensis or the branches on the young trees, with a diameter of 1.0 cm, the seedlings or branches are strong and free of diseases and insect pests, and the side buds are full.

[0045] Step 2, scion preparation: the seed strips are cut short to make scions, each scion is 5.0 cm long, and only one leaf bud on the top is reserved. The bottom of the scion is cut into a wedge shape with a wide outside and a narrow inside with a grafting knife. The length of the cut surface is about 2.0cm, and the cut surface is kept smooth to prevent damage to the cut surface, which will affect survival.

[0046] Step 3, rootstock extraction: select dry willow 2-year-old robust seedlings or branches from young trees as stock, the rootstock is 8.0cm long, and the thickness is determined according to the thickne...

Abstract

The invention discloses a method for improving asexual reproduction survival rate of salix rorida. The method comprises the following steps: selecting seedlings; preparing scions; preparing rootstocks; grating; cutting in a greenhouse; preparing a slotting machine; cutting in the greenhouse; performing management after cutting; transplanting into a large field; and performing management on transplanted seedlings. According to the method for improving the asexual reproduction survival rate of the salix rorida, the salix rorida which is difficult to cut and root is grafted on the rootstock of the saliz matsudana by utilizing the cutting and rooting difference and the grafting healing capability difference between different willow species, so that the asexual reproduction survival rate of thesalix rorida is improved, and the survival rate can reach over 90 percent; because of asexual reproduction, the phenotypic trait of the salix rorida can be fixed; and the method is very suitable forfast propagation of an excellent new variety of the salix rorida with few seedlings. In addition, the seedling raising technology and the required seedling raising facilities of the method are simple,can be mastered by those who grow the seedlings, and are suitable for the current seedling production conditions.

Description

technical field [0001] The invention relates to a seedling asexual propagation technology, in particular to an asexual propagation technology for improving the survival rate of the hard-to-root willow species willow seedlings. Background technique [0002] There are more than 500 kinds of willows, and different willow species have different degrees of difficulty in rooting cuttings. Cuttings such as dry willow and weeping willow are easy to root, and the survival rate of seedlings is relatively high, generally more than 90%. Low, generally between 20-30%. There are also differences in the survival rate of grafting between different willow species, and the survival rate of willow willow grafted on different willows is different. There are some problems in breeding seedlings of Salix argentina with seeds, such as difficulty in collecting seeds, short storage time of seed vigor, large variation in shape of seedlings bred, uneven growth, and inability to fix excellent traits. ...
