氮磷钾的合理配比对水稻生育性状及产量的影响

Effect of Rational Ratio of Nitrogen, Phosphorus and Potassium on Growth Character and Yield in Rice

通过田间小区试验研究了氮、磷、钾不同配比对水稻生长农艺性状和产量的影响。结果表明,合理的三种元素配比可明显改善水稻生育性状,使水稻增产,并通过回归分析得出地块的最佳经济产量和最佳氮、磷、钾的施肥量,有效提高了产投比,取得良好的经济效益。

The plot experiment was carried out to study the effect of ratio of nitrogen,phosphorus and potassium on the yield and agronomic traits in rice,and the results showed that the rational ratio of three elements could improve growth status of rice and increase yield.Relying on regression analysis,the optimum fertilizer amounts for the optimum yield were obtained,the ratio of output to cost rose and finally the benefits were increased.
