One-year two-season corn mechanical planting method

The invention discloses a mechanical planting method for two-season corn in one year, relates to the technical field of corn planting, and solves the technical problems that common corn planted in two-season in one year is difficult to completely mature, the first-season corn is difficult to normally grow, and film mulching and sowing integrated mechanical equipment is lacked. Selecting a grain-feed dual-purpose corn variety with a short growth period and an early-maturing corn variety suitable for machine harvesting; 2, determining a planting period from corn sowing to harvesting; step 3, determining a whole-course mechanized planting mode of harvesting two seasons of silage corn in one year, harvesting one season of silage corn and one season of ear corn in one year, and harvesting two seasons of ear corn in one year. According to the method, effective illumination resources from March to October are fully utilized, the corn variety with the short growth period is selected, the multiple cropping index of th
