摘　　要：在山西省的粮食作物中,玉米占有绝对的主力地位.然而,夏玉米的种植中,果穗缺粒的情况较为严重,对玉米的产量和质量均造成极大的影响.从玉米果穗缺粒和秃顶2个方面入手,分析其产生的原因,结果表明,主要有不良气候条件造成的缺粒、土壤肥力不足造成的缺粒、病虫害造成的缺粒3种情况.在此基础上提出因地制宜、合理密植、玉米去雄、规避高温、追施粒肥、适时灌溉、防治病虫害、人工授粉系列应对措施.In the food crops of Shanxi province,corn occupies the absolute main position.However,in the cultivation of summer corn,the situation of grain deficiency is more serious,which has a great impact on the yield and quality of corn.The causes of corn grain deficiency and baldness are analyzed.The results show that the main reasons of corn grain deficiency are:grain deficiency caused by adverse climatic conditions,grain deficiency caused by insufficient soil fertility and grain deficiency caused by diseases and insect pests.The prevention measures of corn grain deficiency are:adjust measures to local conditions,reasonably close planting,emasculate corn,avoid high temperature,apply grain fertilizer,timely irrigation,control diseases and insect pests and artificial pollination.
