"3414" Fertilizer Trial of Peanut and Analysis on the Optimal Fertilization Amounts

The optimal fertilization amounts of peanut in Hongan county was studied through "3414" fertilizer trial,and establishment of regression equation of fertilization amounts and yield.Insufficient and incomplete fertilization would influence the growth and yield of peanut at different degree.The application of nitrogen,phosphorus and potassium fertilizer with rational proportion could obviously promote the growth of peanut.In medium fertility situation,the optimal amount of N,P2O5 and K2O for peanut was 108.8 kg/hm2,116.4 kg/hm2 and 131.3 kg/hm2 respectively.The analysis result would provide rational fertilization scheme for peanut cultivation and would provide scientific basis for fertilization and utilization of the soil of peanut field.
