Method for improving seed production yield of wild watermelons

The invention provides a method for improving the seed production yield of wild watermelons, and relates to the technical field of watermelon planting. The method comprises the following steps of flower bud collecting: in the pollination period, collecting male flower buds of wild watermelon plants; artificial pollination: selecting female flowers flowering on the wild watermelon plants, and smearing the male flower buds on stigmas of the female flowers; spraying: spraying a compound agent of forchlorfenuron and brassinolide at female flower watermelon embryos; and yield calculation: harvesting seeds and calculating the yield after the wild watermelons are mature. According to the method, the forchlorfenuron and the brassinolide are compounded, and are uniformly sprayed on the watermelon embryos immediately after artificial pollination of the wild watermelons, so that falling of wild watermelon flowers can be prevented, the fruit setting rate of the wild watermelons is increased, and the seed production yield
