| Abstract: | Objective]The research aimed to provide the basis for the fertilization partition and fertilizer formula.Method]3414 testing program was adopted to arrange the field trial.The soil nutrient supplying amount and utilization rate of fertilizer were measured with abundant nutrient deficiency index method and linear analysis.Result]Soil nutrient supplying amount of N,P and K in mulching film field was 156,51 and 72 kg / hm2,and the utilization of N,P and K was 62.5%、30.7% and 24.3%.Soil nutrient supplying amount of N,P and K in bare land was 99,31 and 47 kg / hm2,and the utilization of N,P and K was 53.8%、22.6% and 20.3%.Conclusion]The yield of the peanut in mulching field was improved obviously compared with bare land. |
