研究了N、P、K,种植密度对安豆1号农艺性状及产量的影响,结果表明:施用磷肥生育期比较长、株高较高、底荚较高;磷肥作底肥,花期K肥作追肥,可以提高单株荚数、单株粒数、百粒重和产量;分枝数、单株荚数、单株粒数和百粒重随着密度的增加而减少,单株荚数、单株粒数差异显著,百粒重差异不显著.产量随着密度的增加先增加后减少,呈抛物线状.%The subject has been researched N、P、K, crop density impact on Soy Andou 1 ’s ariculture poperty and yield. That indicates: Using phosphate fertilizer can make the long period of growing 、higher plant、higher bottom legumen; making phosphate fertilizer as fundus fertilizer and using K fertilizer as topdressing of fertilizer during the florescence, can improve the quantity of single plant legumen 、quantity of single plant grain、weithts of hundred piece and yield; Decline of the quantity of branches、 quantity of single plant legumen、 quantity of single plant grain、weithts of hundred piece alonging with the plant density increase, Very different in quantity of single plant legumen and quantity of single plant grain. Weithts of hundred piece usually not different. The yield along with the plant density, increase first reduce later. The figure showing like a parabola.
