The invention relates to the technical field of crop planting methods, and discloses a planting method for drip irrigation seed production of corn, which comprises the following steps of preparation before sowing, soil sealing treatment, seed treatment and other preparation, and sowing, wherein the sowing comprises the following steps: sowing can be carried out when the ground temperature of a 5 cm soil layer is stabilized at 8-10 ℃; 2.2, sowing specification: in order to be matched with the castration machine, a 4-film 8-row mechanical seeder is selected for seeding in the seed production field, the seeding hole spacing of the female parent in the seed production field is 13.5-14.5 cm, and the row spacing is 55-57 cm; 2.3) seeding rate: the sowing amount of the female parent is 2-2.5 kg/mu and the sowing amount of the male parent is 0.2-0.5 kg/mu; 2.4) sowing depth: the sowing depth is 4-5 cm. And other methods such as field management, pest control and the like. The planting method for drip irrigation seed production of the corn can realize high quality and high yield of the corn seed production. |
