ABSTRACT
The method of single-seed precise sowing is frequently adopted in the process of simplified cultivation of maize, which can greatly reduce the quantity of seeds used and save the trouble of thinning and supplementary planting. As large quantities of migrant workers move to the cities, study on the simplified cultivation of single-seed precise sowing has great realistic significance. High field seedling emergence rate is one of the main reasons for the high yield of single-seed precise sowing. Under the condition of single-seed precise sowing, to ensure planned number of individual plant, it is recommended that it should be sowing based on the field seedling emergence rate is recommended. High field seedling rate is one of the main reasons for the high yield of single-seed precise sowing and the number of hundred-dot spots is the upper-convex parabola function of field emergence rate. The results have guiding significance to the maize seeds production and single-seed precise sowing to some degree.
