虞城县2007年冬小麦冻害分析

摘要

According to the local survey of frozen injury and the meteorological data of Yucheng county in 2007, the cause of frozen injury was analyzed. The results showed that early sowing, planting too much, unsuitable tillage measures and the abnormally high winter temperatures of 2007 made wheat grown too fast, and the growth period was advanced. Without cold acclimation, the ability of frost resistance was weakened which became the main reason of winter wheat subjected to injury by frost.%根据2007年虞城县冬小麦冻害的调查资料,结合当地的气象资料,分析了冬小麦冻害的成因.结果表明:早播、播量大、耕作措施不当以及7007年冬前和冬季气温异常偏高,小麦生长过快,发育期提前,未经抗寒锻炼,抗冻能力减弱,成为冬小麦遭受冻害的主要原因.
