地膜覆盖栽培技术应用于玉米制种生产,具有增产的作用,能有效地提高玉米制种的产量和质量。地膜覆盖可以提高地温、抑制杂草、生长整齐、花期集中,而且还使父、母本都能在适播期内播种,保证了全苗,而且又能使花期抢在高温连雨期前相遇,提高结实率,从而提高了制种产量和质量。本试验的主要的目的就是使育种者尽快了解和掌握地膜技术的特点和实际的投入成本和产出效率,对提高育种者的经济效益和加速地膜玉米育种技术的推广极为有效的。
Plastic film mulching cultivation techniques used in seed production of corn, with the role of yield, can effectively improve the yield and quality of seed production. Film mulching can improve the ground temperature, weed suppression, tidy growth, flowering focus, but also the parent and the female can sow in the sowing period to ensure that the whole seedlings, but also to get the flowering rush in the high temperature even rain met, Improve the rate of seed setting, thus improving seed production and quality. The main purpose of this experiment is to make breeders understand and grasp the characteristics of membrane technology as well as actual input cost and output efficiency as soon as possible, which is very effective to improve the economic benefits of breeders and accelerate the popularization of plastic corn breeding technology.
