冬小麦越冬冻害死亡,是当前新疆生产上的大问题。在少雪、严寒年分,常因品种选择不当,造成大量死亡。因此,研究品种忍受低温的能力及冬麦耐寒性的一般规律,具有重要意义。兹将一九六三至一九六四年在米泉县五家渠就20个品种进行的试验结果报道如下。 Winter wheat winter frost death, is the current production of Xinjiang’s major problems. In less snow, cold years, often due to improper selection of species, resulting in a large number of deaths. Therefore, the study of the ability of varieties to endure low temperature and winter wheat cold tolerance of the general rule, is of great significance. The results of the tests carried out on 20 varieties at Wujiaqu in Miquan County from 1963 to 1964 are reported below.
