应用长期定位试验方法,研究了洞庭湖区非粮食作物棉花-油菜轮作下,农民习惯施肥(TF)、配方施肥(NPK)及有机肥和化肥不同配比模式[有机肥来源氮占配方肥总氮量的50%(50%OM) 、30%(30%OM)和10%(10%OM)]的作物产量和土壤养分的变化,以期为相应作物种植制度下的合理施肥提供参考。研究结果表明:在本试验施肥量及有机无机肥配比下,有机肥和化肥配施显著提高了棉花和油菜的产量,且以50%OM处理产量最高,各处理产量的顺序为50%OM>30%OM>10%OM>NPK>TF>CK(不施肥对照);当有机氮施用量占总氮量的50%时(50%OM处理),棉花和油菜产量分别比NPK处理高24.52%、29.57%,比习惯施肥(TF)处理分别高46.03%和49.07%。同...

An experiment was conducted under cotton-rapeseed crop rotation system in upland areas of Dongting Lake to de-termine the effect of different fertilization modes on soil fertility and crop yield. The treatments in the experiment included none fertilization (control), conventional fertilization (TF), formula fertilization (NPK) and different combinations of chemical and organic fertilizers (10%OM, 30%OM and 50%OM, in which 10%, 30% and 50% of total N was from organic fertilizer). The results indicated that combined inorganic and organic fertilizer application greatly improved yields of cotton a...
