| 摘 要： | 2006~2008年采用"3414"完全试验设计方案,对中稻施用氮、磷、钾肥的效应进行了田间试验,试验结果表明:氮、磷、钾对中稻产量的影响大小表现为氮(钾、磷。经回归分析,中稻最佳的施肥量为每667 m2施用纯氮10.1 kg、磷肥4 kg、钾肥6.5 kg。在此最佳施肥量条件下,中稻产量达到518.1 kg/667 m2,且施肥经济效益最好。

| Abstract: | The effects of nitrogen,phosphorus and potassium fertilizer application in middle-season rice were studied in Fuan city during 2006 ~ 2008 through "3414" full-test design.The test results showed that the effects of nitrogen,phosphorus and potassium fertilizer on the yield of middle-season rice revealed the following order: nitrogen > phosphorus,potassium.Regression analysis concluded that the optimum fertilization quantity was pure nitrogen 10.1 kg/667 m2,phosphorus fertilizer 4 kg/667 m2,potassium fertiliz... |
