Planting method for selenium-rich watermelons

Abstract

The invention discloses a planting method for selenium-rich watermelons. The planting method includes the steps of 1, watermelon seed sprouting, wherein sterilized and soaked seeds are put into sprouting boxes, and seeds after sprouting are obtained; 2, watermelon seedling cultivating, wherein shoot tips of the seeds after sprouting are put into seedling cultivating discs upwards, watermelon seedlings are obtained, selenium-rich leaf fertilizer and an alkaline water solution are sprayed to the watermelon seedlings one time morning and evening every day respectively, and illumination is increased at night; 3, watermelon seedling transplanting, wherein a selenium-rich nutrient solution is sprayed in the initial stage of transplantation, the watermelon flowering pollination stage and the fruit setting stage till watermelons are matured. According to the planting method for the selenium-rich watermelons, the treating methods such as the selenium-rich nutrient solution, the selenium-rich leaf fertilizer and a selenium-rich solution are adopted; the selenium content in the seedling stage is increased, the selenium content in the watermelons is increased, the germination rate of the watermelon seeds is increased, the incidence rate is reduced, and the yield of the selenium-rich watermelons is effectively increased.
