Method for improving yield of hybrids in artificial hybridization of Salix matsudana

The invention discloses a method for improving the yield of hybrids in artificial hybridization of Salix matsudana. The method comprises the following steps: (1) selection of mother plants; (2) preparation of male flower shoots: selecting male plants with good hybridization affinity to Salix matsudana as male parents, wherein the male flower shoots are required to have diameters of 0.5-0.8 cm andlengths of 50-80 cm, and thinning the male flower shoots by removing 1/3 weak and small male flower buds; (3) preparation of female flower shoots, wherein the female flower shoots have lengths of 0.7-1.0 m and diameters of 1.0-2.0 cm; (4) culturing of the flower shoots; (5) pollen collection; (6) pollination; (7) management after pollination; and (8) hybrid collection. The method of the inventioncan effectively overcome the characteristic of thin and weak branches of Salix matsudana, improves pollen quality by thinning flowers, ensures the supply of nutrients in a hybrid development cycle through branch thinning and f
