Abstract: 【Objective】To explore the effects of different fertilizers and their ratios on the yield and quality of Chinese cabbage.【Methods】Five different treatments was designed：no fertilizer （T1,CK）,single chemical fertilizer （T2）,2/3 chemical fertilizer combined with 1/3 organic fertilizer （T3）,2/3 chemical fertilizer + 1/6 organic fertilizer combined with 1/6 straw （T4）,and pure organic fertilizer （T5）.Among them,the contents of nitrogen,phosphorus and potassium in T2,T3 and T4 were the same,while the contents of nitrogen in T5 and T2,T3,T4 were the same without considering the content of phosphorus and potassium.【Results】T3 treatment had the highest yield and survival rate of Chinese cabbage,the values were 188.01 t/hm² and 90.70% respectively,and the highest nitrogen fertilizer agronomic efficiency and partial productivity,the values were 163.33 kg/kg and 696.34 kg/kg respectively.T3 and T5 treatment had the highest soluble sugar content,reached 2.58%,and T5 treatment had the highest VC content,which was 30.6 mg per 100 g.【Conclusion】Under the experiment condition of this study,T3 treatment 2/3 chemical fertilizer combined with 1/3 organic fertilizer was a better mixed application.
