摘　　要：采用田间试验研究了不同NP配比对南农88-31大豆产量和品质的调节效应。结果表明,最有利于南农88-31大豆籽粒产量和蛋白质产量提高的NP配比是N150kg/hm2与P2O575kg/hm2;NP配比可以调节大豆叶面积和干物质积累,但这种调节效应主要归功于氮肥的作用,随施N量增加,大豆叶面积和干物质积累增加;NP配比对大豆籽粒蛋白质含量的调节效应不明显。A soybean cultivar Nannong 88-31 was used to carry out a fetilizing experiment of different NP proportions, and to study the adjusting effects of NP proportion on soybean yield and protein content. It proves that NP prorotions have effects on grain yield and grain protein yield of soybean. The optimum NP proportion for soybean seed yield and protein content of Nannong 88-31 is N150kg/hm^2 to P205 75kg/ hm^2 ; NP proportion may adjust soybean leaf size and accumulation of dry substance. But the effect mainly attribute to nitrogenous fertilizer. The increase of soybean＇s leaf size and accumulation of dry substance is in accordiance with the amount of nitrogenous fertilizer. The adjusting effect of NP proportions on protein content of soybean seed is not obvious.
