| 摘 要： | 采用311-B最优D饱和设计和旱棚微区试验的方法,于2003～2006年在辽西半干旱区开展了滴灌条件下水肥耦合对春玉米产量效应的试验研究。结果表明:氮肥对产量的作用最大,磷肥次之,水分最小;水肥耦合效应大小顺序为:磷水耦合>氮磷耦合>氮水耦合;获得最高产量14298.36kg/hm2的施氮量为285.49kg/hm2,施磷量为128.79kg/hm2,灌水下限为田间持水量的69.29%。

| Abstract: | Using rain proof installations,with 311-BD-saturation optimum design,during 2003~2006,field experiments of water and fertilizer coupling on spring corn yield were conducted in semi-arid areas of western Liaoning province.Results show that nitrogen quantity was the chief factor to affect spring corn yield,phosphorus quantity was the second factor,irrigation quantity was the third factor.The effect order of interaction is:water and phosphorus coupling>nitrogen and phosphorus coupling>water and nitrogen coupli... |
