摘　　要：本试验以棉花为试材,设置无氮、无磷、无钾和全肥4个处理,研究不同处理对棉花株高、单铃重、产量、含水率、含杂率、收获指数的影响,并计算氮磷钾肥利用率,为阿克苏市棉花科学合理施肥提供指导。结果表明,阿克苏市棉花全年施用尿素975 kg/hm^(2)、重过磷酸钙300 kg/hm^(2)、硫酸钾300 kg/hm^(2)可以提高棉花株高、平均单铃重、产量和收获指数,降低含杂率和含水率,氮、磷、钾肥利用率分别为40.4%、19.1%、43.9%。This experiment used cotton as the experimental material and set up four treatments(nitrogen free,phosphorus free,potassium free,and full fertilizer).The effects of different treatments on cotton plant height,single boll weight,yield,moisture content,impurity content and harvest index were studied,and utilization efficiency of nitrogen,phosphorus,and potassium fertilizers was calculated,so as to provide guidance for scientific and reasonable fertilization of cotton in Aksu City.The results showed that the annual application of urea 975 kg/hm^(2),heavy superphosphate 300 kg/hm^(2),and potassium sulfate 300 kg/hm^(2) to cotton in Aksu City could improve cotton plant height,average single boll weight,yield,and harvest index,reduce impurity content and water content,the utilization efficiency of nitrogen,phosphorus and potassium fertilizers were 40.4%,19.1%and 43.9%,respectively.
