Abstract In this paper，the high mountain vegetable fertilization and continuous cropping situation of Enshi city were investigated in selected and representative areas．The results indicated that in Enshi city households applying compound fertilizer during planting high mountain vegetable were high up to 94.1%，and only 41.0% applying manure fertilizer．The farmer households applying boron and magnesium fertilizer were few．For high mountain vegetable（Chinese cabbage，peppers，radishes and cabbage），the variation coefficient of nitrogen，phosphorus and potassium fertilization were all bigger，which reflected there was bigger arbitrariness in vegetable fertilization．Except for cabbage，nitrogen application rate and vegetable yield was negatively correlated，and the very significant differences was observed between nitrogen application rate and Chinese cabbage yield，which showed that high nitrogen application level had become an important limiting factors for the vegetable yield improvement．In Enshi city，the areas of 4 vegetables continuously cropped for 5 years or more，was up to 45.7%．Vegetable cropping years and disease occurrence were very significantly correlated．
