玉米栽培在定向密植的基础上,在肥、水、温、湿等适宜的环境条件下,产量主要由穗粒数、穗粒重所决定。玉米后期生长发育环境条件的好坏直接决定着穗粒数和穗粒重,90％以上的产量在此期间产生。但种植户往往都不重视玉米的后期管理,容易导致雌花退花而败育,造成秃头玉米、半边玉米、癞子玉米的比率上升;或使玉米植株提前衰老,
Maize cultivation in the direction of close planting on the basis of fertilizer, water, temperature, humidity and other suitable environmental conditions, the yield is mainly determined by the number of grains per spike. The growth and development of late maize environmental conditions directly determine the number of grains per spike and grain weight, more than 90% of the yield during this period. However, farmers often do not attach importance to the latter part of maize management, easily lead to abortion female flower abortion, resulting in bald corn, half corn, razor clam increased; or corn plants premature aging,
