摘要
研究了冬小麦不同品种,在不同播期条件下,主茎叶片伸展期、主茎叶片露尖所需要的时间和积温。明确了不同品种播期与冻害、品种播期与基本苗的关系。
The time and the accumulation temperature of main stalk blade extension period and dew point of different varieties winter wheat and sowing time were studied. At the same time, the relationships between sowing time and the freezing injury, the sowing time and the basic seedling of different varieties winter wheat were confirmed.
