Abstract：The correlative analysis on the 17 major fertility index of paddy field in the middle areas of Jilin province,i.e.Jiutai,Yongji,Dehui,Yushu,Changchun indicated that the other indexes all arrived significant level except pH.The content of total Zn is higher,Ca and K are lower,and the other elements are middle.Compare to the world,China and Jilin,the content of Zn is higher about 41.38%,4.80% and 8.48% respectively; the content of K is lower about 1.14%,27.96% and 30.52% separately.Through the multiple variable main component analysis,3 major component characteristics were ascertained: the first is Mg and N,the paddy soil in Yushu is the typical type like this; the second is Zn and P,in Dehui; the third is Ca and Zn,in Changchun.The experiments results showed that K and organic fertility were need in the middle of Jilin province,and meanwhile followed by Zn fertility.
