Increasing Effect of Formula Fertilization on Maize

To proof the effect of fertilization on maize,and guide farmers to adopt fertilization technology to achieve efficiency of production,the purpose of improving the yield,increase production,maize formula fertilization and contrast demonstration conventional fertilization was carried in Kuankuo town,Suiyang county.The results showed that the maize grain at growth of post-formula fertilization stage is more fully,kernels per row of maize in demonstration area is more than conventional fertilization,and thus higher yields than conventional fertilization yield by 9.40%.The economic benefits in accounting,it's 1279.26yuan/hm2 higher than conventional zone(according to local metering habits converted into 82.28yuan/667m2),the new production ratio 4.47,which will invest an additional 1yuan can get 4.47 yuan of new capacity out,that is a net increase of 3.47 yuan gains.while,output of formula fertilization reached the target yield index,it's indicated that formula fertilization parameters can be use into practice widely.conventional fertilization does have its limitations,nutrient ratio imbalance,impact on the formation of the yield,the need for improvement.
