摘　　要：试验采用27个大豆品种,结合大豆生育期每月降水量,采用随机区组设计,研究了降水量对大豆籽粒油分含量的影响和不同类型品种油分含量与降水量的关系。结果表明,除8月份外,大豆品种油分含量与生育期各月份降水量都达到5%显著水平以上的负相关。6月份和7月份的降水对大豆油分含量形成起到了重要作用。此外,7月份降水对高油大豆品种油分形成起关键作用,而9月份降水对高蛋白和中间类型大豆品种油分形成更重要。The article was conducted with 27 soybean varieties and precipitation during the growing period,with randomized block design,studied the effect of precipitation on soybean oil content and correlation between different varieties and precipitations.The results showed that except August,there was significantly negative correlation at 5% level between oil content of soybean and the precipitations in other months.Precipitations on June and July played an important role on soybean oil content.In addition,the precipitations in July played a key role on oil content in high oil soybean varieties,but the precipitations in September showed more important roles on oil content in high protein and intermediate varieties.
