冬小麦是我区的主要粮食作物,但以冻害为主的越冬死苗是小麦生产上的重大灾害,严重威协小麦稳产高产。多年来不少人对播期、品种、冬灌等防冻措施进行了研究。但,由于对冻害的原因、种类认识不清,特别是对麦苗抗冻能力变化规律认识不清,对这些农业措施的防冻机制也认识不清。本文用近年冻害生态学研究方法,对冬灌、品种、播期的麦苗抗 Winter wheat is the main food crops in our region, but winter frostbite overwintering dead seedlings is a major disaster in wheat production, serious Wei Association wheat stable and high yield. Many people over the years sowing date, varieties, winter irrigation and other antifreeze measures were studied. However, due to the reasons for the frost damage, species do not know well, especially the law of frost resistance of wheat seedling changes in the law is not clear, the antifreeze mechanism of these agricultural measures are not clear. In this paper, in recent years, frost damage ecology research methods, winter irrigation, variety, sowing date of wheat seedlings resistance
