Method for improving asexual reproduction survival rate of salix rorida

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 exc
