摘　　要：比较了植物生长调节剂芸苔素内酯和复硝钠在不同浓度下对棉花产量因素和纤维品质的影响。芸苔素内酯和复硝钠在适宜的剂量和浓度下可以促进棉花吐絮,增加霜前花产量,并改善棉花纤维品质,但不能增加棉铃总数和棉花总产量。This paper compared the effects of two specials plant-growth regulator, brassin-olide and sodium-para-nitrophenolate, on the cotton yield factors and fiber quality in different concentration in summer cotton field. They could increase the yield of pre-frost cotton, improve the fiber quality of lint cotton in appropriate dosage and concentration, but could not increase total cotton yield and bolls.
