通过田间小区试验 ,研究钾肥和棉花专用肥的应用效果 ,为合理施用钾肥及优化棉花专用肥配方提供理论依据 ,1998年我们进行了棉花专用肥和钾肥肥效试验 ,报告如下。1　材料与方法试验地设在精河县城关一队 ,肥力较均匀 ,土壤质地为砂壤土 ,前茬棉花。土壤有机质 16.49g/ kg,全氮 Through the field plot test, the application effect of potash and cotton special fertilizers was studied, and the theoretical basis was provided for the rational application of potash fertilizers and the optimization of cotton special fertilizer formula. In 1998, we carried out the fertilizers testing of cotton special fertilizers and potash fertilizers, the report is as follows. 1 Materials and Methods Experimental ground located in Jinghe County team, more uniform fertility, soil texture of sandy loam, the former crop of cotton. Soil organic matter 16.49g / kg, total nitrogen
