施用缓释氮肥对夏玉米产量和氮肥利用率的影响OA
Effect of Controlled-release Nitrogen Fertilize(r) on Summer Corn Yield and Nitrogen Use Efficiency
[目的]为夏玉米合理施用氮肥提供理论依据.[方法]以夏玉米为试验材料,通过田间小区试验,研究了缓释氮肥对夏玉米产量和氮肥利用率的影响.[结果]缓释氮肥掺比普通氮肥及缓释氮肥减量施用可以在0.05水平显著提高夏玉米产量和氮肥利用率.缓释氮肥掺混普通氮肥以SCU70％+ PU30％处理玉米产量、籽粒吸氮、秸秆吸氮、吸氮总量和氮肥利用率最高,在0.05水平显著高于其他等氮处理,产量为7 284.0 kg/hm2,增幅达10.63％ ～ 33.02％,氮…查看全部>>
[ Objective ] To provide theoretical basis for the reasonable application of nitrogen fertilizer for summer com. [ Method ] A Held plot experiment was conducted to study the impact of slow-release nitrogen fertilizer on the yield and nitrogen use efficiency of summer com. [ Result ] The combined application of common nitrogen and slow-release nitrogen fertilizer as well as the reduction of slow-release nitrogen fertilizer application increased com yield and …查看全部>>
