摘要
在水泥测坑和防雨蓬遮雨下,研究棉花花铃期、吐絮期,土壤不同湿度对棉花产量和纤维品质的影响,并用^(14)C示踪研究了土壤水分对产量和纤维品质影响的机理。同时用模糊数学的方法对构成产量和纤维品质的诸指标进行了综合评判,得出土壤湿度在65％～75％的条件下,皮棉产量最高,棉纤维发育最好,纤维品质最佳的结果。
The influence of soil moisture on cotton yield and lint quality was studied from flowering to boll-opening period of cotton in cement puddle sheded by waterproof cloth, Their mechanism was tested by labelled atom <sup>14</sup>C, The targets of yield components and lint quality were evaluated by fussy mathematics comprchensively, The results indicated that the highest lint yield, best lint growth and lint quality wcre gained when soil moisture varied in 63—75％.
