Abstract: 【Objective】Effects of NPK application on yield and quality of cabbage and NPK absorption of cabbage were studied.【Methods】The effects of NPK ratio on yield,quality,plant nutrient and soil nutrient of cabbage were studied with “sugan 25” as the experimental material and “3414” as the implementation plan.【Results】The fresh weight and dry weight of each part of cabbage were increased after NPK treatment.The content of VC was increased and the content of nitrate was decreased.Nitrogen,phosphorus and potassium fertilization increased the nutrient content of each part of the plant and improved the soil nutrient.Among them,treatment E(N2P2K2) has the highest yield,the best quality and relatively good plant and soil nutrients.【Conclusion】Considering the indexes of yield,quality,plant nutrient content and soil nutrient,N (300 kg/hm2),P2O5 (75 kg/hm2) and K2O (360 kg/hm2) are recommended to be a good ratio of NPK,which has certain guiding significance for cabbage cultivation.
