不同施氮量对大豆蛋白质和脂肪含量的影响

在不同施氮水平下对大豆合交98-1667进行叶片氮素、籽粒蛋白质及脂肪含量的影响研究。结果表明:N2(90 kg.hm-2,纯氮)处理中大豆叶片氮素和籽粒蛋白质含量最高,其次是N1(45 kg.hm-2,纯氮)处理,N0和N3处理在叶片氮素含量和籽粒蛋白质含量中的差异不显著,说明不施氮或高施氮对大豆生长均不利,尤其对大豆氮素和蛋白质含量的抑制影响较大。但对大豆脂肪含量的影响不显著。

Effect of Different Nitrogen Application on Protein and Fat Content in Soybean

Effect of leaf nitrogen content,seed protein and fat content on dwarf soybean hybrid 98-1667 were studied in different nitrogen application.Results showed that the highest of leaf nitrogen content and seed protein content was the N2 treatment（90 kg·hm-2,purity nitrogen）,the second was N1 treatment（45 kg·hm-2,purity nitrogen）,leaf nitrogen and seed protein content were no significant difference between N0 and N3.It was indicative of negative growth with soybean in no nitrogen and high nitrogen application,and tight binding inhibitors on nitrogen and protein content of soybean was bigger.But the effect of fat content of soybean was no significant difference.
