摘    要:为研究氮、磷、钾肥对早稻产量和经济效益的影响和测土配方施肥提供依据,在湖北省赤壁市利用"3414"试验设计布置了早稻氮、磷、钾肥料效应试验.结果表明,早稻施用磷肥效果最好,最高增产稻谷2 300 kg·hm-2,相应增产率达36.7%,纯增收入2 984.4元·hm-2;钾肥增产稻谷1 075 kg·hm-2,增产率为14.8%,纯增收入1 186.8元·hm-2;氮肥增产稻谷677 kg·hm-2,增产率为8.9%,纯增收入365.7元·hm-2.通过配置三元二次和一元二次肥效模型,结合试验实际情况,确定早稻N、P2O5和K2O的最高产量施用量分别为180.1、57.3和67.5 kg·hm-2,最佳经济施用量分别为108.5、55.4和59.1 kg·hm-2.

关 键 词:早稻  "3414"肥效试验  施肥效果  推荐施肥量

Abstract:This paper studied the effect of nitrogen,phosphorus and potassium fertilization on early-season rice by the 3414 fertilizer experiment,which was conducted in Chibi city,Hubei province.The result showed that the effect of P fer-tilization on yield and economic benefit was the largest,the next was K,and N fertilization was the smallest.The highest increment of N,P and K were 677,2300 and 1 075 kg.hm-2,higher than control by 8.9,36.7 and 14.8%,respectively.The net income of N,P and K were enhanced by 365.7,29...
Keywords:early-season rice  3414 fertilizer experiment  fertilization effect  fertilizer recommendation
