中文摘要	为了探讨南疆棉花水肥耦合作用,试验实行3因素5水平311-B拟饱和最优回归设计,通过对灌水量(W),施氮量(N),施磷量(P)与棉花产量关系的分析,拟合出回归模型: Y=4685.48+78.95X1+61.66X2-14.58X3-84.51X12-101.94X22-120.75X32-79.56X1X2-38.73X1X3-14.61X2X3(Y为产量,X1为灌水量,X2为施氮量,X3为施磷量).结果表明:在试验条件下各因素对产量影响的顺序为W(X1)>N(X2)>P(X3),说明在本试验条件下,灌水量的作用居于首位,其次是氮肥和磷肥;各因素交互作用效应顺序为WN>WP>NP;由方程拟合的组合方案是灌溉量(Z1)为5 765.24 m3/hm2,施氮量(Z2)为281.76 kg/hm2,施磷量(Z3)为104.73 kg/hm2时,棉花籽棉最高产量(Y)达到4 707.94 kg/hm2
英文摘要	Artificial water control experiments in cotton field were conducted in arid region of Xingjiang to study the effect of water and fertilizer coupling on cotton yield with 3 factors and 5 levels of 311-B quasi-plump. The order of various factors impacting on the production was water(X1)>N(X2)>P(X3).The effect of irrigation quantity ranked first, followed by nitrogen and phosphorus in the trials;the order of interaction effect of various factors was WN>WP>NP.It showed that nitrogen had leading function in crop growth under different irrigation conditions. Interaction effect of various factors promoted yield, and the interaction effect between nutrient factors as well as water was higher than N and P.The results showed that the amount for highest yield 4 707.94 kg/hm2 was nitrogen 281.76 kg/hm2, phosphorus 104.73 kg/hm2 and water 5 765.24 m3/hm2
