To promote the improvement and development of saline-alkali land in Cangzhou City,the effects of different growth of saline-alkali land on soil improvement were analyzed by using saline-alkali land jujube as experimental material.Methods:The five year old jujube was divided into three groups,T1,T2 and T3,according to the growth of jujube,and the effects of different growth of jujube on the pH value,the content of trace elements in soil and the number of soil microorganisms were compared.Results:①pH value:Jujube jujube could effectively reduce soil pH value,and T1 group had the most significant effect on pH value,and there was a difference a-mong groups(P<0.05);②Soil trace elements:the contents of nitrogen,phosphorus,iron,zinc,potassium and other trace elements in T1 group were significantly higher than those in T2 and T3 groups,and the differences among groups were significant(P<0.05).③The number of soil microorganisms:the number of bacteria in group T1>Group T2>group T3,the number of fungi in group T1<group T2<group T3,and there were significant differences among groups(P<0.05).Conclusion Jujube jujube has significant effect on soil improvement in saline-alkali area,which can reduce soil pH value and increase soil nutrient content,and the improvement effect of ju-jube jujube with different growth potential is also different,the better the growth of jujube jujube,the more obvious the soil improve-ment effect.
