| 摘 要： | 2009年在黑龙江省鹤山农场进行6个土壤水分水平控制的大豆盆栽试验,土壤水分分别是:15%、18%、24%、30%、40%、48%.结果表明:土壤水分和大豆产量有很好的二次曲线关系,决定系数R<'2>达到0.97,大豆产量在田间持水量条件下达到峰值,低干、高于田间持水量时,大豆均减产,田间持水量80%～133%减产幅度...

| Abstract: | The research was aimed to study the impact of different soil moisture conditions on soybean yield and the distribution of biological organs.Soybean pot experiments were done at Heshan Farm in Heilongjiang Province in 2009,and the soil moisture content treatments were 15%,18%,24%,30%,40% and 48% respectively.The results showed that there was good conical relationship between soil moisture and yield(R2=0.97),and the yield reached the peak with 30%(field capacity,FC).The yield would decrease when soil moisture... |
