摘要
遗传因素、水分、温度、光照条件和密度因素等是子粒败育的影响因素。选用优良品种、适宜密度、合理施肥、适时灌溉及排涝可以减少子粒败育,保证高产稳产。
In recent years, maize yield was decreased by leaves early ageing and kernels abortion, which were caused by factors of heredity, moisture, temperature, illumination and plant density. The measures of decreasing the kernels abortion are selecting good maize variety, proper density, rational fertlhzation, timely irrigation and drain flooded field, all of these lead to a high and stable yield of maize.
