Hybrid corn seed production method for respectively and intensively planting parents

The invention discloses a hybrid corn seed production method for respectively and intensively planting parents, and particularly relates to the field of field crop seed production. Male and female parents are mechanically planted separately; when the male parent is about to gather and loosen pollen, collecting and storing the cnidium monnieri, and keeping the pollen activity; when the female parent develops to reach the ceiling, mechanical castration is carried out; according to the ratio of the spinning rate of the female parent, awakening the male parent to disperse pollen, putting the collected pollen into a special nutrient solution, dispersing, and pouring into an unmanned aerial vehicle for spraying; water and fertilizer are applied according to requirements, so that male parents and female parents are high in yield; the male parents are harvested independently and continue to serve as the male parents in the next year, and after female parents are harvested, selected and subjected to impurity removal,
