Abstract:The soil buffer action of super high yield and ordinary yield maize from the Jilin province’s four areas included Huadian,Qian’an,Lishu and Yushu was studied.The results showed that all acid-alkali buffer curves assumed the counter-S shape,which have two inflection points and display the different sensitive sectors.The ordinary yield soil’s buffer capacity from Huadian and Lishu were bigger than their high yield soils.On the contrary,acid-alkali buffer capacity of Qian’an and Yushu’s ordinary yield soil was smaller than that of high yield soils.The Jilin Province soil’s buffer capacity did not absolutely relate to its maize yield.The organic content,cation exchange capacity and physical clay content were positive related to the buffer capacity,but the initial pH value was negative correlated with it,that is to say,raising the soil organic content,cation exchange capacity,clay content and reducing the soil pH value is helpful to enhance its acid-alkali buffer capacity.
