摘要: 通过对棉花产量、施肥量及其它管理措施的调查,分析了新疆主要植棉县棉花的施肥现状及存在问题.对棉花种植户生产状况分析结论如下:(1)在棉花生产中,农民施肥盲目性较大,区域间有机肥施用量不平衡,南疆农民较重视有机肥的施用;(2)肥料投入不平衡严重,施肥量上有较大的差异,很少施用钾肥,氮肥(N)投入量0~495 kg/hm2、磷肥(P2O5)0~813.75 kg/hm2、钾肥(K2O)0~49.5 kg/hm2、有机肥0~60 000 kg/hm2;(3)氮磷钾配比不协调,氮磷钾配比为1∶0.14~2.9∶0~0.28;(4)施肥品种单一,主要是以尿素和磷酸二铵为主,只有33.9;的农户施用专用肥或者复合肥.针对以上问题提出了棉花生产的施肥改进措施.
