| 摘 要： | 本文比较分析了2004年与常年气象资料和四个试验品种的表现,结果表明:2004年6、7月份和8月上、中旬降雨量严重不足(较历年少近150 mm),造成土壤和大气干旱,大豆生长关键时期(即开花期、结荚期、鼓粒期)供水不足,使大豆株高降低,主茎节数、单株荚数、粒数减少,百粒重降低,产量降低的事实。说明了大豆6、7、8月份降水对大豆产量的重要性。。

| Abstract: | Yield and traits between the climate in 2004 and normal year with four soybean varieties was investigated.The results showed that the inadequate rainfall(150 mm less than a normal year) caused soil and air draught and thus inade-quate water supply for soybean during flowering,pod setting and pod filling.Although pest and other diseases were less infected,plant height,node and pod number as well as 100 seed-weight(3~5 g) was decreased,resulting a yield de-cline around 50 Kg/666.7 m2. |
