Effect of Different Applicating Methods of Fertilizers on Maize Yield and Soil Nutrients

The effect of different application methods of fertilizers on maize yield and soil nutrients was studied by 3-year field experiment.The results showed that N、P、Zn and organic fertilizer(M) all increased the maize yield significantly by 3 387.0～ 5 473.0 kg.hm-2,and the increasing rates were from 48.0%～77.5%;treatments of N240P150M15 000 and N240P75M15 000 had the best effect,and the yields were 12 536.0 kg.hm-2 and 12 438.8 kg.hm-2 respectively.After 150 kg.hm-2 P was applied in the first year,decreasing P application by 50% didn't influence maize yields significantly in the second year and third year,the soil available P still kept high amount.Application of mixed fertilizers increased soil nutrients and improve the soil fertility.
