Study on High Yield and High Effeciency Fertilization Techniques of Spring Maize

Fertilization is the important measure to ensure the crop yield，this study analyzed the effect of blind investment on yield in regular fertilizer, through field experiments and the comparison of the different effect of regular fertilizer and balanced fertilization. The result showed that the yield of regular fertilization is slightly higher than the balanced fertilization, but the income is significantly less than the balanced fertilization. Comparing to the regular fertilization, the balanced fertilization increased 3662yuan per Ha, net income increased 40.9%. The nutrient uptake of regular fertilization is equal to balanced fertilization of balanced fertilization, which showed that a large number of nutrient left in the soil, and will cause potential ecological risks to ecological environment.
