摘要

摘要: 通过在江汉平原腹地江北农场5个分场布置中稻的"3414"肥料效应试验,研究了氮、磷、钾肥对中稻产量和经济效应的影响。结果表明,施肥对中稻的增产效果明显,中稻施用氮肥的效果最好,磷肥次之,钾肥最小。稻谷最高增产695.1~2 414.7 kg·hm-2, 相应增产率为8.6%~37.8%, 纯增收1 011.2~3 563.5 元·hm-2。通过配置三元二次和一元二次肥效模型,结合田间试验实际情况,确定中稻的最佳施肥量为纯 N 180~200 kg·hm-2,P2O5 55~60 kg·hm-2,K2O 50~60 kg·hm-2。

Abstract: A "3414" fertilizer experiment was carried out in Jiangbei farm of five fields to determine the yield and economic effect of nitrogen, phosphorus and potassium fertilization on mid-season rice. The result showed that the effect of fertilization on mid-season rice yield increase is obvious: the effect of N fertilization on mid-season rice yield and economic benefit was largest,the next was P, and K fertilization was the smallest. The highest in yield of N,P and K were 695.1-2 414.7 kg穐m-2, and which were 8.6%-37.8% higher than contro1.The net income of N, P and K were 1 011.2-3 563.5 Yuan穐m-2, respectively. According to fertilizer effect, N, P2O5 and K2O application rate to get the highest profit were 180-200 kg穐m-2, P2O5 55-60 kg穐m-2, and K2O 50-60 kg穐m-2, respectively.
