试验表明，土壤含盐量与棉花产量及棉花株高、单株有效铃数呈极显著负相关，与单铃重呈显著负相关。土壤含盐量低于０．２４％时，对棉花产量及其构成因子有促进作用；含盐量高于０．２４％时，盐分对棉花开始产生不良影响，超过０．５０％时对棉花的危害逐渐加重，超过０．７０％时棉花产量仅为土壤含盐量为０．１７％时的４７％，单株有效铃数仅为其４８．７％－５２．８％，株高为其４３．６％－４７．８％。土壤中盐分各组分与棉花产量及其构成因子呈极显著负相关。土壤盐分对棉花纤维品质影响不大。
The results showed that there was a significant negative correlation between soil salt content and cotton yield, cotton plant height, effective boll number per plant, and significant negative correlation with boll weight. When soil salinity was less than 0.24%, the yield and its components of cotton could be promoted. When the salt content was higher than 0.24%, the salt began to have an adverse effect on the cotton. When the soil salinity exceeded 0.50% Of the damage gradually increased, more than 0.70% of the cotton yield was only 47% of soil salt content of 0.17%, the effective number of bolls per plant is only 48.7% -52.8%, plant height Its 43.6% -47.8%. Soil salinity components and cotton yield and its constituent factors were significantly negatively correlated. Soil salinity has little effect on cotton fiber quality.
