冬小麦抗寒性是指冬小麦对低温的抵抗能力。近年来,冬小麦冻害几乎每年都有不同程度的发生,对冬小麦的产量产生不利的影响,给农业的生产造成一些损失。为了给生产上提供抗寒性较强的品种,全国农技推广中心和北京市种子管理站特设置该试验。试验对于冬小麦品种的审定及推广具有重要的指导意义。通过几年来所做的冬小麦抗寒性鉴定试验,简述了抗寒性鉴定的方法,及如何评价,总结了影响冬小麦品种抗寒性能的几种因素。冬小麦能否安全越冬主要取决于品种自身的抗寒性,但也受其他因素如播种质量、田间管理、天气寒冷程度、降水(雨、雪)量等因素的影响,对冬小麦抗寒性评价需综合考查。
Winter wheat cold resistance refers to the resistance of winter wheat to low temperature. In recent years, winter wheat frost damage occurs to varying degrees almost every year, adversely affecting the yield of winter wheat and causing some losses to agricultural production. In order to provide the production of cold hardiness varieties, the National Agricultural Technology Extension Center and Beijing Seed Management Station set the trial. Test for the validation and promotion of winter wheat varieties has an important guiding significance. Through several years of winter wheat cold tolerance identification test, briefly described the method of cold resistance identification, and how to evaluate and summarize several factors that affect the winter wheat cold hardiness. Whether winter can be safely wintered mainly depends on its own cold tolerance, but also affected by other factors such as sowing quality, field management, cold weather, precipitation (rain, snow) and other factors, evaluation of winter wheat cold resistance needs Comprehensive examination.
