Abstract
Different located field experiments were conducted to discuss the technique of soil fertility improvement.The results evaluated that the soil fertility improvement of second layer increased the grain yield of maize,made the soil physical properties better under different tillage systems,and analyzed the nutrient status of soil in different grain yield levels at central of Jinlin province and control way.The best yield application rate and the maximum yield application rate were established.Zn and Mg increased significantly the grain yield of maize.
