| 摘 要： | 在免耕抛秧种植模式下进行“3414”肥料效应试验,通过建立氮、磷、钾施肥量与产量的回归模型,探索当地水稻的最佳施肥量.结果表明,氮磷钾施用量均为中等水平时,产量和经济效益达到最佳；各类型函数所获得的最佳经济产量表现为一元函数＞二元函数＞三元函数.结合一元、二元、三元肥料效应函数及实际生产而获得的推荐施肥指标:最高产量施... |

| Abstract: | A 3414 design fertilizer experiment was carried out under no-tillage cultivation to explore the best fertilizer model by establishing the relation of nitrogen,phosphorus,potassium fertilizer application rate with the rice yield.The result showed that the best yield and profit could be reached by the middle level of nitrogen,phosphorus,potassium fertilizer application.According to fertilizer effect and the actual production,the highest yield could be got by the rate of N,P2O5 and K2O application:197.70,73.05... |
