The invention discloses a method for improving the crossbreeding efficiency of lespedeza, and relates to the technical field of lespedeza breeding, and the method comprises the following steps: spraying melatonin to improve the proportion of blooming and atresia in a flower bud non-color exposure or flower bud color development period; pollen of other lespedeza germplasm flowering in the same period is collected and mixed with pollen of male parent lespedeza to pollinate female parent lespedeza, a phytophagous composite medium is adopted during pollination, and a biodegradable liquid film is sprayed after pollination so as to improve the pollination success rate and the fruit setting rate. According to the method, multiple measures are taken at the same time, the fruit setting rate and the maturing rate of lespedeza are synergistically increased, operation is easy and convenient, time is saved, and the lespedeza crossbreeding efficiency is remarkably improved. 本发明公开了一种提高胡枝子杂交育种效率的方法，涉及胡枝子育种技术领域，包括在花蕾未露色或花蕾显色期
