| 摘 要： | 在赤壁市利用“3414”试验设计布置中稻氯、磷、钾肥料效应试验。结果表明．中稻施用氮肥的效果最好，稻谷增产量最高达2325kg·hm^-2，相应增产率为39．1％，纯增收入2737．5元·hm^-2：施用钾肥的增产量为777kg·hm^-2，增产率为10．4％，纯增收入678．5元·hm^-2；施用磷肥的增产量为400kg·hm^-2，增产率为5．1％，纯增收入288．8元·hm^-2。通过拟合三元二次和一元二次肥效模型，确定中稻N、P205和K20的最高产量施用量分别为169．8、84．5和163．7k·hm^-2，最佳经济施用量分别为153．7、61．5和120．8kg·hm^-2。 |

| Abstract: | This paper studied the effects of nitrogen,phosphorus and potassium fertilization on mid-season rice by the 3414 fertilizer experiment,which was conducted in Chibi city,Hubei province.The result showed that the effect of N fertilization on mid-season rice yield and economic benefit was largest,the next was K,and P fertilization was the smallest.The highest in-crement of N,P and K were 2 325,400 and 777 kg.hm-2,and which were 39.1%,5.1% and 10.4% higher than control,re-spectively.The net income of N,P and K ... |
