Abstract: The rational fertilization to summer maize under zero-tillage cultivation has been paid more and more attentions by farmers.Comparative experiments between no fertilization and five ways of fertilization under conditions of same fertilizer-rate and same management were conducted.Result showed that the unequivalent distance fertilization method was the best way for summer maize under zero-tillage.Under this condition,chlorophyll content was 3.94mg/g,leaf area was the largest and grain yield reached 7646.3kg/hm²,increased by35.23%.
