| 摘 要： | 为探讨氮磷钾肥料施用对水稻产量的影响以及氮、磷、钾养分交互作用,以水稻为研究对象,进行氮磷钾配比试验。结果表明：氮、磷、钾肥之间存在一定的交互作用,本试验条件下,N—195.0kg/hm^2、P2O5—60kg/hm^2、K2O—150kg/hm^2时最有利于各养分效果的发挥,氮、磷、钾肥合理配施对水稻产量有重大影响。

| Abstract: | In order to explore the effect of nitrogen（N）,phosphorus（P） and potassium（K） fertilizer on the rice yield and their nutrient interaction,a NPK proportioning experiment in rice was conducted.The results show that there are beneficial interactions between N,P and K.On the trial conditions,N 195.0kg / hm^2,P2O5-60kg / hm^2 and K2O-150kg / hm^2 have synergetic effects on nutrient and yield,appropriate application rates of N,P and K have important effect on rice yield. |
