摘要
运用生物统计分析方法 ,较系统地分析了北疆地区复播油葵籽粒灌浆期间气候因子对油葵灌浆时间、灌浆速率、千粒重的影响规律。结果表明 ,复播油葵灌浆期平均气温低与日最高气温相对较低是延长灌浆时间的有利条件 ,平均气温低与气温日较差小对提高油葵千粒重最为有利 。
The effect of climatic factors on thousand grain weigh. Filling velocity and filling period in filling stage of multiple cropping oil sunflower in north Xinjiang ,were studied by using statistical principles and analytical methods. The result shows that, the suitable conditions for extending filling period are lower mean temperature and about lower maximum temperature,and a little diurnal change of temperature are of great advantage for increase of thousand grain weight of oil sunflower, the change of filling velocity on thousand grain weight is bigger than that of filling time.
