土壤总盐与产量、单株有效铃、单铃重、株高呈极显著负相关。但在土壤含盐量小于0.24％的范围内,对棉花产量及结构因子有促进作用,大于0.24％以上盐分对棉花开始产生不良影响,当盐分为0.50％以上时,对棉花的危害逐渐加重。土壤含盐量平均大于0.70％以上时,棉花产量为土壤含盐量平均为0.17％时的47.8％,单株有效铃为48.7—52.8％,株高为43.6％—47.8％。分盐除HCO_3~-外,其余各分盐与产量及其结构因子呈极显著负相关。土壤盐分对棉纤维品质的影响不明显,没有显著的相关性。 Soil total salt and yield, effective bolls per plant, boll weight, plant height were extremely significant negative correlation. However, within the range of soil salinity less than 0.24%, cotton yield and structure factors were promoted. Salt above 0.24% had an adverse effect on cotton. When the salt content was above 0.50%, the damage to cotton was gradually aggravated. When the soil salinity was above 0.70%, the cotton yield was 47.8% when the soil salinity average was 0.17%. The effective boll number per plant was 48.7-52.8% and the plant height was 43.6% -47.8%. Salt addition to HCO_3 ~ -, the rest of the salt and yield and its structural factors were significantly negatively correlated. Soil salinity has no obvious effect on the quality of cotton fiber, there is no significant correlation.
