新疆喀什地区和北京地区基本属于同一纬度,冬季最冷月平均气温与北京相似或稍低,冬麦的适宜播期和北京相同。据了解,北京地区的冬麦一般冬前不开始幼穗分化,只有个别年份冬前开始分化(1955年)。喀什地区冬麦冬前有无开始幼穗分化的可能,目前尚未见到有关报道。为此,我们于1983年元月18日起,对这个地区目前种植面积较大的几个冬小麦品种进行了20多天的粗浅观察,除个别品种外,它们的幼穗冬前已经开始分化,这为掌握适宜播期和进行麦田管理提供了依据。
The Kashi area in Xinjiang and the Beijing area belong to the same latitude. The coldest average temperature in winter is similar or slightly lower than that in Beijing, and the suitable sowing date for winter wheat is the same as that in Beijing. It is understood that the winter wheat in Beijing generally do not start spike differentiation before winter, only individual years before the beginning of winter differentiation (1955). Kashgar winter wheat before winter without spike differentiation may have not yet seen the report. To this end, we started in January 18, 1983, the region currently planted a few large winter wheat varieties were more than 20 days of crude observation, with a few species, except for their young panicle before winter has begun to differentiate, This provides the basis for mastering sowing date and wheat field management.
