摘　　要：湘杂棉8号在不同密度下干物质积累动态均遵循Logistic曲线规律。随着种植密度的增加,单株及各器官干物质积累量减少,而单位面积总干物质积累量增加。种植密度为39 000株/hm2干物质积累多,有利于高产。This research result indicated that dry material accumulation movements of Xiang za 8th follow lagistic curve law under different plant density. Each cotton and every organ dry material accumulation decreased but total dry material added per unit area by density added. The dry material accumulated abundantly under 39 thousands per hm2, and the density was good for high yied.
