| 摘 要： | 利用淮北地区宿州站1994-2007年14a的夏大豆生长发育和农业气象观测资料,采用C值逼近法和决定系数(R2)最大化法拟合夏大豆的生长曲线,分析了影响夏大豆生长的关键气象因子和生育阶段。结果显示:夏大豆开花-鼓粒期对气象因子的变化最敏感,生长量与气象因子间的拟合效果达到极显著水平;平均气温日较差、降水量和降水天数是开花-鼓粒期的主导影响因子。其它时期对气象因子不很敏感。

| Abstract: | Based on 14 years data of growth and development of summer soybean and agro-meteorological observation from Suzhou station,the impact of reproductive stages and the key meteorological factors on summer soybean growth was analyzed using SAS software. The results showed that summer soybean flowering to filling was the most sensitive stage to changes of meteorological factors,and the fitting model was at the very significant level,and that the average diurnal temperature range,rainfall and rainfall days were m... |
