| Abstract: | The experiment on fertilizer using efficiency of summer maize was conducted to explore the us?ing efficiency of nitrogen,phosphate and potash,master the approach of formula fertilization,reduce the use of fertilization and increase the utilization of fertilization. The results indicated that the fertilizer application amount reduced by 75kg/hm2,while the average utilization efficiency of nitrogen,phosphate and potash in?creased by 9.13% and the yield increase rate of summer maize was over 5%. |
