Abstract: In order to avoid impact of seed fertilizer on seed quality and inhibition of chemical fertilizer on seed biological activity when traditional seed fertilizer was mixed，and avoid phenomenon that fertilizer was scattered and distributed when seed fertilizer was applied vertically，and utilization rate was not high because there was no specific seed，a no-tillage precision seeder was designed for directional hole sowing of corn.The equipment could realize high-efficiency no-tillage precision sowing and fertilization of corn with fixed quantity，distance and hole. Seeds and fertilizers could meet requirements of hole forming and separate application.Location distribution and thickness of soil layer between two caves could meet requirements of agricultural technology.Moreover，adjustment between sowing amount and fertilization amount is independent，and at the same time，the cost is reduced，the yield is increased，and the soil is protected.
