摘　　要：对不同密度下湘杂拂8号农艺性状、产量构成和纤维品质进行研究。结果表明：果枝数、果节数、单株成铃数、成铃率均随着密度的增加而逐渐降低；12000株，hm^2处理的籽棉、皮棉产量，成铃数／hm^2最低。30000株/hm^2产量最高，39000株/hm^2次之，适宜密度为301300—39000株/hm^2；各处理间棉圩维平均长度、比强度、伸长率差异不显著，21000株／hm^2处理的整齐度最高，为85．19％。12000株/hm^2处理整齐度最低，为84．38％。This test studied the expression of growing characters and yielding and quality about Xiangzamian No. 8 in different density. The results indicated that fruit branches, fruit notes, fruit bolls per plant and cotton boll setting ratio were all decreased with the growing density added; the unginned cotton yield, lint cotton yield and fruit bolls per hm^2 of 12 thousands per hm^2 were all the lowest, the yield of 30 thousands per hm^2 was the highest, and 39 thousands per hm^2 was the second. 30 thousands - 39 thousands per hm^2 was the suitable density ; the first half of the average length, fiber specific strength and elongation rate were not influenced by the density. The uniformity index of 21 thousands per hm^2 was the highest, it was 85.19%, the 12 thousands per hm^2 was the lowest, it was 84.38%.
