摘要: 应用三因素五水平二次通用旋转组合方法，试验研究不同水肥用量对大田间作玉米、大豆产量的影响结果表明，三因素对玉米产量的影响依次为水>N>P，对大豆产量的影响依次为水>P>N；水、肥互作效应中水的效应大于肥，且肥效随灌水量的增加而提高。

Abstract: By using the design of three factors-five levels-quadratic general spinning ，the effects of applying different amounts of N，P fertilizers an d moisture on the yields of maize and soybean under the eondition of inter-cropping were studied．The results show that the effect of thre factors on soybean yield is moisture> N>P．the effect of three factors on soybean yield is mo isture>P>N．while in the eficiency of mo isture-fertilizer interaction the moisture efficiency iS more than that of fertilizer，and the fertilizer efficiency increases with the increasing of irrigation．
