随着自治区农业生产的发展，特别是棉花生产的发展，无机氮磷化肥投入量不断增加，土壤中钾素亏损严重。为了解在棉花作物上补施钾肥的效果，研究了钾肥对棉花生长发育及产量的影响。l材料与方法试验地点设在疏勒县罕南力克任九村六组。土壤类型为灌淤灰土，土壤质地为中壤，肥 With the development of agricultural production in the autonomous region, especially the development of cotton production, the input of inorganic nitrogen and phosphorus fertilizers is increasing, and the potassium loss in the soil is serious. In order to understand the effect of potash fertilization on cotton crops, the effects of potash fertilizer on cotton growth and yield were studied. l Materials and Methods The test site is located in Shulejihanhan Lectra nine village six groups. Soil type for filling silt soil, soil texture for the soil, fertilizer
