This study uses the method of field trials and lab tests to discusses the consistent in the NPK fertilizer application conditions,different biological fertilizer and NPK fertilizer application of Jizhang 8 potato different growth and quality of crops, increase organic fertilizer(T2), soil physical and chemical properties have obvious changes, as well as the economic characters and yield of Ji zhang potato 8also has the change, the change rule between the three processing T2 T3 T1, namely the NPK + Biological organic fertilizer NPK +Fulvic acid potassium NPK, but reached the maximum at T3 soil available nutrients, three processing the change rule between the T3 T2 T1, namely the NPK + Fulvic acid potassium NPK + Biological organic fertilizer NPK, the experimental results show that the combination of organic manure and chemical fertilizer reasonably and effectively on soil fertilizer and potato yield and improving quality has important significance.
