| 摘 要： | 研究了氮、磷、钾化肥配合施用对水稻产量的影响,结果表明:在磷、钾养分相等的条件下,当氮肥的用量超过21.0 kg/667 cm2时,水稻的增产效果不显著;水稻氮肥的用量范围为9.0~21.0 kgkg/667m2。氮、磷、钾化肥的合理施用对水稻产量及其构成因子有非常显著的影响。

| Abstract: | The effects of combined application of N,P and K on rice yield were studied.The results showed that under the conditions of equual P and K amount,when the dose of N in rice was higher than 21.0 kg/667 cm2,the yield-increaseing effect N,P and K fertilizer reasonable application of the N,P and K fertilizer resonable appleication of N,P and K fertilizer effect on rice yield and itscomponent factors. |
