一、冬小麦2015年9月中下旬北疆大部天气过程频繁,延缓了冬麦的播种进度,大部冬麦播种期偏晚,其余时段冬麦区温度适宜,大部麦区有一定的降水,麦田底墒良好,气象条件对冬麦的播种出苗较为有利。冬麦区苗期气温偏高、降水偏多、麦田土壤墒情较好,气象条件对大部冬麦冬前生长、抗寒锻炼较为有利。大部冬麦区冬前≥0℃积温在350℃·d以上,达到了冬前壮苗所需的积温水平,有利冬麦安全越冬)。
First, winter wheat in late September 2015 most of the weather in northern Xinjiang, frequent delays in the sowing of winter wheat, most of the winter wheat sowing late, the rest of the winter wheat temperature is appropriate, most of the wheat area has some precipitation , Good moisture at the end of wheat field, meteorological conditions of winter wheat sowing more favorable. Winter wheat germination temperature is high, more precipitation, wheat field soil moisture is better, meteorological conditions for most winter wheat winter growth, cold exercise is more favorable. Most of winter wheat before winter ≥0 ℃ accumulated temperature above 350 ℃ · d, reached the winter before the seedlings required for the accumulation of temperature levels, favorable winter wheat winter winters).
