通过不同氮磷钾优化配比施肥对高蛋白大豆品质和产量及构成因素影响的研究。结果表明:最有利于高蛋白大豆子粒产量和蛋白质产量提高的氮磷钾配比是N150kghm-2、P2O590kghm-2和K2O75kghm-2。氮磷钾优化配比可以调节大豆叶面积和干物质积累,但对大豆籽粒含量的调节效应不明显。
Study on the Effect of Different Ratio NPK Fertilizers on Quality, Yield and Components of High Protein Soybean. The results showed that the ratio of N, P and K which was the most favorable to high protein soybean yield and protein yield was N150kghm-2, P2O590kghm-2 and K2O75kghm-2. The optimal ratio of N, P and K could regulate soybean leaf area and dry matter accumulation, but had no obvious effect on soybean grain content.
