| 摘 要： | 选择有代表性的区域调查了湖北省恩施市高山蔬菜产区施肥及连作状况。结果表明：恩施市高山蔬菜种植中施用复合肥的农户比例高达94.1%，施用农家肥的农户比例仅为41.0%，施用硼、镁肥的比例很低；大白菜、辣椒、萝卜、甘蓝4种蔬菜的氮、磷、钾施肥变异系数均较大，反映了菜农施肥的随意性很大；除甘蓝外，其他3种蔬菜的施氮量与蔬菜产量呈负相关，大白菜甚至达到了极显著负相关水平，这表明施氮水平偏高已经成为恩施市蔬菜产量提高的重要制约因子；恩施市4种蔬菜连作时间在5 a以上的面积达到了45.7%，蔬菜的种植年限与发病率的相关性达到了极显著相关水平。

| 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． |
