对宜昌市高山蔬菜基地的土壤肥力状况进行了分析。试验结果表明，目前宜昌市高山蔬菜基地土壤酸碱度(pH值)较适宜蔬菜生长，但有机质含量普遍低下，普遍缺氮、缺磷，速效钾含量不均等且差异极大，有的土壤钾含量缺乏或极缺乏，有的土壤含钾量丰富。土壤的培肥措施为施用石灰，减小土壤的酸度；增施有机肥，增强土壤团粒结构的形成和微生物活性，改善其通透性能；因地制宜，合理轮作，选择性种植作物，以达到逐步培肥地力的目的；利用掺沙客土进行土壤改良，以改善土壤质地。%In the paper, we analyzed soil fertility conditions of Yichang alpine vegetable bases. The results showed that, the soil acidity and alkalinity (pH value) of the investigated alpine vegetable bases in Yichang was suitable for the growth of vegetables, but their organic content was generally low. The soil was lack of nitrogen and phosphorus, and the potassium content was not equal and different base soil possessed great different potassium content. Some soil was lack or extremely lack of potassium, but some was rich in potassium. Fertilization measures for the Yichang alpine vegetable bases were as follows:applying lime to adjust the soil acidity, increasing application of organic manure fertilizers to enhance the formation of soil aggregate structure and microbial activity and improve the soil permeability, selective growing crops to increase soil fertility gradually, and using sand soil for soil improvement to improve the soil texture.
