| Abstract: | Based on the design of testing soil before applying fertilizer according to the formula,the effects of different fertilization treatments on maize yield were analyzed from the yield increase degree,the fertilization benefits and the comprehensive utilization rate of the fertilizer.The experiment results show that the optimal fertilization model was applying fertilizer 21 kg/ 667 m2 in total and the proportion of N︰P2O︰K2O = 1︰1.14︰0.86.Thus,the yield increase degree,the fertilization benefits and the comprehensive utilization rate of the fertilizer were the highest,i.e.20.9%,$102.7/667 m2,29.3%,respectively.This research provides an important reference for the scientific fertilization of summer maize in Wuqing District. |
