摘 要:
为探求土壤pH值、可溶性总盐及其离子组成对棉花出苗的影响,对土壤的可溶性总盐、盐分离子组成及pH值进行经典统计、相关性分析和模糊聚类。结果表明,K++Na+、Cl-质量分数呈强变异,pH值呈弱变异,SO2-4、Ca2+、Mg2+呈中等或中等偏强变异;pH值及SO2-4、Ca2+、Mg2+与土壤可溶性总盐显著相关;出苗和不出苗情况下,SO2-4、Ca2+、可溶性总盐差异显著;Cl-、K++Na+归为一类,HCO-3为一类,SO2-4、Ca2+、可溶性总盐归为一类,均比较稳定。

摘 要:
In order to explore the effects of soil soluble total salts,salt ion composition,pH value on cotton emergence,soil soluble total salt,salt ion composition,pH value were analyzed by the methods of classical statistics,correlation analysis and fuzzy cluster analysis.The results showed that:concentrations of K++ Na+,Cl-were strong variations,pH value was weak variation,and concentrations of SO2-4,Ca2+,Mg2+ were the middle or little stronger variations;There were significant relationships between soil soluble total salts and pH value,SO2-4,Ca2+,Mg2+concentrations;there were significant differences of SO2-4,Ca2+, soluble total salts between different treatments;It was stable that Cl-,K++Na+were classified as a class,HCO-3was classified as a class,and SO2-4,Ca2+,total soluble salts were classified as a class.
