在玉米整个生育期内,影响玉米正常生长发育的因素很多,高温、干旱是影响玉米产量的主要因素。近年来,随着气候不断变暖,通辽市气候异常,雨热不同季,玉米生育期内降水量少,持续的高温、干旱给玉米正常生产带来严重的危害。为了减少或避免损失,必须采取相应的预防措施,选育抗旱品种是首要任务,其次应加强田间管理,科学施肥,合理密植,改变传统的耕作方式,营造田间小气候。
During the whole growth period of maize, there are many factors that affect the normal growth and development of maize. High temperature and drought are the main factors affecting maize yield. In recent years, with the climate warming, Tongliao City, anomalous climate, rainy season, less corn during the growth period of precipitation, continuous high temperature, drought to the normal production of corn serious harm. In order to reduce or avoid losses, corresponding precautionary measures must be taken. Breeding drought-resistant varieties is the most important task. Secondly, we should strengthen field management, scientific fertilization, close planting rationally, change traditional farming methods and create microclimates in the field.
