小麦是适宜于温凉气候的作物,在籽粒形成和灌浆期最适宜的温度是20—22℃,超过22℃就会影响小麦灌浆,使千粒重降低,籽粒不饱满,降低产量。因之,干热风是小麦生产的大敌,危害面广,常引起小麦大幅度的减产,使小麦收成很不稳定。为了解决干热风问题,这几年许多地方介绍了石油助长剂保护法,氯化钙浸种法等办法进行预防,但因小麦面积大,劳力、资金、机械投资大,使这些方法还不能在生产中普遍推广。为了找到更好的切实可行的办法,我们将乌什地区一九七六——一九七九年的小麦生产实际,结合农业气象记载和我所
Wheat is a suitable crop in warm climates. The most suitable temperature during grain formation and filling is 20-22 ℃. When it exceeds 22 ℃, wheat will be affected by grain filling, grain weight will be reduced, grain will not be full, and yield will be reduced. Therefore, the hot and dry wind is the enemy of wheat production, a wide range of hazards, often causing a substantial wheat yield, the wheat harvest is very unstable. In order to solve the problem of dry and hot wind, in many places in recent years oil prevention agent protection and calcium chloride seed soaking are introduced for prevention. However, due to large area of wheat, large investment in labor, capital and machinery, these methods can not be used in production In general promotion. In order to find a better and practical solution, we will combine the actual production of wheat in the Wushi Prefecture from 1976 to 1979 with agricultural weather records
