| 摘 要： | 试验采用二次回归"3414"设计,通过田间小区试验研究了盘锦地区典型稻作区氮磷钾配合施用对水稻产量的影响。通过主因素、单因素效应分析,定量地评价了氮肥、磷肥和钾肥用量与水稻产量的关系,提出了目标产量的最优氮磷钾组合方案。从水稻最大经济产量和经济效益综合考虑其最优氮肥(N)用量范围为260～320 kg/hm2,最优磷肥(P2O5)用量范围为150～200 kg/hm2,最佳钾肥(K2O)用量范围为70～100 kg/hm2。

| Abstract: | The "3414" design of quadratic regression was adopted in this experiment.Effects of interaction among nitrogen,phosphorus potassium coordinating on the yield of rice were studied in Panjin.The effect of N,P and K on the yield of rice was studied quantitatively based on main and single factors effect analysis.The optimal composite scheme of N,P and K was 260~320 kg/hm2,150~200 kg/hm2,70~100 kg/hm2.This result provided an optimum composite scheme of N,P and K for target yield. |
