摘　　要：为了筛选出鄱阳湖棉区种植短季棉品种中棉所58的最佳密度,结合鄱阳湖棉区短季棉生产情况,设6个密度梯度,采用随机区组设计进行试验,测量不同处理的棉花农艺、产量性状,为鄱阳湖棉区发展短季棉生产提供科学依据。结果表明:密度为12 0000株/hm^2较为适宜,其籽棉、皮棉产量显著或极显著高于其他处理,且与中熟棉对照品种常规密度处理之间无显著差异。In order to screen out the optimum planting density which was suitable for short-season cotton CCRI 58 in Poyang Lake cotton region,6 different density treatment experiments with randomized block design were designed to measure the cotton yield and agronomic characters and provide scientific basis for the development of Poyang Lake short-season cotton production.The results showed that the seed cotton and lint yield of the suitable density 120000 plants/hm were significantly or extremely significantly higher than the other treatments,and had no significant difference with the control variety（the conventional density treatment,middle maturing cotton Ganmian 11）.
