| Abstract: | Objective]The research aimed to provide a theoretical guidance for high-yield,high efficiency,soil fertility and agricultural protection.Method]'3414' full implementation design scheme was adopted to study soil nutrient indexes and fertilization index system.Result] The apple yield under different treatments was studied,soil nutrient indexes were established and revised,soil nutrient status was evaluated,and the recommended fertilization was described.Conclusion] Soil nutrient indexes should be set up and verified,and corresponding recommended fertilization index should be established before soil testing and formula fertilizer were carried out. |
