摘要
1999～2001年在沿江地区灰潮土上研究了硫磺粉、硫肥95对棉花生长发育、皮棉产量和棉纤维品质的影响。试验结果表明:施用硫肥能提高棉花的株高、果枝数、蕾数、成桃数和茎基粗,还能提高伏桃比例,促进棉花生育后期的生长发育,增加棉花产量,改善棉纤维长度、整齐度、比强度等品质指标。硫肥的适宜用量为45～60kg/hm2。施用硫肥95的增产效果比硫磺粉的要好。
The studies on the effects of element sulphur and S95 on the growth of cotton ,yield and quality of lint were conducted from 1991to 2001 at the plain area along the Yangtze River. The results indicated that the application of S could increase the plant height, fruit bearing branches, bud, bolls and the diameter of bottom stem, and also raise the proportion of summer boll (Fu Tao), enhance the growth of the cotton at the late stage,increase the lint yield,improve the quality parameters of cotton lint such as the fiber length, uniformity and special intensity etc. The optimum rate of S application was 45～60 kg/ha, The yield responses of S95 were more obvious than elemental S.
