摘　　要：通过田间试验,以大豆为供试作物。采用二因素二次饱和D-最优设计(206)进行水肥试验,对不同水肥处理的滴灌大豆产量进行了初步研究。试验结果表明,在供试条件下,水、氮对产量有明显的促进作用,而且氮素作用大于灌水作用;两因素交互作用对大豆产量的影响为正效应。Soybean is a crop for experiment.Duality quadratic saturating D-optimum design is carried out through field experiments.For different kinds of irrigation,water and N fertilizer treatment drip soybean yield are studied.The results indicate that both water irrigation and fertilizer have produced effects on the soybean yield under the experiment conditions,and the effect of N fertilizer application is more significant than that of irrigation water.There are positive interactions between water,N and soybean yield.
