水肥耦合对小麦产量的影响研究

Effect of Water and Fertilizer Coupling on Wheat Yield

为探明小麦不同生育阶段水肥耦合效应,设置田间试验分析其对小麦产量及产量构成因素的影响。结果表明,在N(1高氮)条件下,W(1拔节水+灌浆水)、W(2拔节水)处理均可实现肥水高效耦合,并获得530 kg/667m2以上高产,而N2、N(3中氮)水平下产量下降。

In order to find out the different growth stages of wheat on coupling effect,on coupling analysis of the wheat yield and yield formation factors.The results indicate that the high nitrogen N1 conditions,W1 W2 processing all can realize,water efficient coupling,obtain 530 kg/667m2 over the high yield,and N2 N3 nitrogen level,the yield to drop.
