Abstract：The relationship between wheat yield and nutrient variation of 5 soil types (skeleton soil, brunisolic soil,cinnamon soil,moisture soil and Shajiang black soil)during 1981 ~2008 were analyzed in Zhucheng City.The results showed that different soil types showed different nutrient variation trend in the same natural climate conditions.The soil nutrients clustered distinctly.Correlation and regression analyses of trend yield of wheat and soil nutrient were conducted.The results indicated that the effects of different soil nu-trients of different soil types on trend yield were significantly different.The rapidly available phosphorus con-tent was most significantly correlated with trend yield,and then the available N.The interaction of rapidly a-vailable phosphorus and other nutrient factors was very important to trend yield.In conclusion,the application of P fertilizer and its matching with other nutrients were the keys of wheat production and high and stable wheat yield.
