摘　　要：[目的]结合阜阳地区短季棉生产状况,对中棉所50进行不同密度试验,为阜阳地区发展短季棉生产提供科学依据。[方法]采用随机区组设计,分别设计四种不同种植密度,测量棉花农艺及产量性状。[结果]最适宜的种植密度为90 000株/hm2,籽棉和皮棉产量最高,果枝数、株铃数、单铃重、衣分等一些农艺性状和产量指标总体表现好于其它密度梯度。[结论]适宜的种植密度可显著提高中缅所50的农艺及产量性状。According to the production condition of short season cotton Zhongmiansuo 50, the different density experiments were conducted. [Method] On the basis of randomized block design experiment the four different planting density were used to measure the cotton yield and agronomic characters. [Result] The yield of raw cotton and lint were high with the suitable density 6000. The agronomic characters of boll number, bolls per plant, were better than others. [Conclusion] The suitable planting density would significantly increase the agronomic characters and yield.
