Simplified planting method for radishes rich in organic selenium

The invention discloses a simplified planting method for radishes rich in organic selenium. The method comprises the five steps of preparation before sowing, mechanical soil preparation and sowing, water and fertilizer integrated management, scientific selenium application, mechanical harvesting and cleaning, through mechanical planting and harvesting, labor-saving and efficient planting of the radishes is achieved, the labor consumption is reduced by 97% or above, and the production cost is effectively reduced. Furthermore, components of fertilizer are compounded, and the selenium content is optimized, so that the yield of the radishes is remarkably increased, and the average yield per mu reaches up to 5400 kg; and meanwhile, content of various nutritional components such as organic selenium, soluble sugar and vitamin C in the radishes are remarkably increased, the yield and quality of the radishes are both improved, high economic benefits are achieved, and coordinated and sustainable development of the ecol
