摘要: 利用濉溪县1970-2004年大豆统计产量和相应的实测气象数据,统计分析结果表明:濉溪县大豆幼苗期和鼓粒期的降水量、花荚期和全生育期的雨日与气象产量呈显著直线相关,大豆生长季节降水及其时空分布是造成实际产量波动的主要原因。根据对当地历年降水量的统计分析,确定了大豆生育期的适宜降水量范围,为大豆生产和管理提供依据。

关键词: 夏大豆, 降水量, 产量

Abstract: Based on the observed meteorological and soybean yield data from 1970 to 2004 in Suixi County,the statistical analysis of relationship between precipitation and yield of summer soybean was made.The result showed that the correlation between precipitation during seedling,filling stage and precipitation days during podding and the whole growth period and soybean yield were significantly positive.Soybean yields were mainly constrained by spatial and temporal abnormity characteristics of summer precipitation in soybean growing areas.The suitable precipitation range during the growing period of summer soybean was determined.
