| 摘 要： | 通过多点田间试验研究了农四师66团氮、磷肥施用量对小麦产量及其相关性状的影响,建立了氮、磷肥施用量与小麦产量及产量构成因子间的效应函数方程。试验结果表明：小麦生产中氮肥对穗数、穗粒数、产量的影响高于磷肥;氮肥（N）的适宜用量为137～407kg·hm-2,此时可获得小麦最佳经济产量为7413—11071kg·hm-2。小麦产量对土壤养分的平均依存率为63％。

| Abstract: | The influence of the application amount of nitrogen and Phosphorus fertilizer on wheat yield and relevant properties were investigated with field experiments.Fertilizer response functions of nitrogen and Phosphorus for wheat were established in this study.The result shows that spike number,grains per spike,and yield of wheat were influenced significantly by nitrogen,but not by phosphorus.The suitable application amount of nitrogen fertilizer is from 137 to 407kg/hm2 in this region.For wheat yield,the averag... |
