摘　　要：脂肪含量是大豆品质的重要指标之一,运用多种数理统计方法,对黄淮海区试南组5年夏大豆区域试验测定的大豆品种脂肪含量与平行观测的气象资料进行分析。结果表明:影响脂肪含量的综合气候关键期为9月上、中旬(鼓粒中后期),主导气象因子是日照时数,气温日较差对其也有重要影响。Fat Content is one of the key indicators of soybean quality. By various mathematic and physical statistic methods, fat content of soybean varieties, identified in the consecutive 5-year test in Huanghuaihai Region, have been analyzed in line of the parallel climatic data. It shows that the overall key climatic period effecting fat content is early and medium September, while the dominant factor is sunlight lengths, and daily difference in temperature also plays a great role.
