Field experiment was conducted to investigate effects of different organic fertilizer rates on soil microbe and quality and yield of cabbage.The results indicated that more application of organic fertilizer could increase the amount of soil microbe.With the increase of organic fertilizer application rate，germ，actinomycetes and fungi showed a growth trend.When application of organic fertilizer was more than 7 500 kg/hm2，the growth trend of the number of soil microbes slowed.Applications of organic fertilizer could obviously increase yield and improve quality of cabbage.The yield and the content of Vc and reducing sugar of fresh cabbage was the highest under organic fertilizer as 7 500 kg/hm2.
