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667m2施用纯氮10．1kg、磷肥4kg、钾肥6．5kg。在此最佳施肥量条件下，中稻产量达到518．1kg／667m^2，且施肥经济效益最好。
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 fertihzation quantity was pure nitrogen 10. 1 kg/667 m^2, phosphorus fertilizer 4 kg/667 m^2, potassium fertilizer 6.5 kg/667 m^2. Under the best fertilization quantity condition, the yield of middle - season rice could reach to 518.1 kg/667 m^2 , and the economic benefit of fertilization was the best.
