| 摘 要： | 采用小区对比试验方法,探讨了氮磷钾肥不同施入量对水稻新品种盐粳218产量的影响。结果表明,氮肥施入量对产量的影响程度最大,各处理比其平均单产增幅-15.3%～8.0%,磷肥各处理比其平均单产增幅-2.9%～1.7%,钾肥各处理比其平均单产增幅-3.3%～1.8%。同时根据氮、磷、钾肥施入量对盐粳218产量影响的函数方程求得与该品种高产高效栽培相配套的氮(N)、磷(P2O5)、钾肥(K2O)适宜施入量为16～20 kg/667 m2、6.5～8.5 kg/667 m2、5.0～7.0 kg/667 m2。在本试验条件下水稻新品种盐粳218可获得598.3～625.0 kg/667 m2的产量。

| Abstract: | The Effect of nitrogen,phosphorus and potassium amounts on yield of Yanjing218 were studied with comparative experiment.The results showed that nitrogenous fertilizer had the greatest effect on yield which growing rate were from-15.3% to 8.0%,the growing rate of phosphorus fertilizer and potassium fertilizer were from-2.9% to 1.7% and from-3.3% to 1.8%.The optimal contents about high efficiency of nitrogen,phosphorus and potassium amounts were 16～20 kg/667 m2、6.5～8.5 kg/667 m2、5.0～7.0 kg/667 m2 which counted by functional equation.Under the circumstances of the experiments the yield of Yanjing218 were 625.0 kg/667 m2. |
