Abstract
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.
