Abstract
Long term trials of effect of different fertilization measures on maize production were carried out in the semi arid area of west Liaoning and careful observation were taken out on the 10 th year's shot out period. The results show that using N and P can notably improve the seedling height and leaf area; Without N fertilizer for years, it will strain synthesis of chlorophyll in maize leaf, and it will go against the synthesise of organic matter. N fertilizer is in favor of the widening of maize leaf and the haleness of maize springs, and this is the base of maize high yield.
