对湖北省丹江口库区柑橘产业土壤肥力进行了评价。选取pH值、有机质、全氮、碱解氮、全磷、速效磷、速效钾等肥力因子,再将各属性值分级标准化,采用修正的内梅罗指数对各地块进行土壤肥力综合评价。结果显示:柑橘产业土壤生产力质量指数属肥力一般水平,碱解氮和有机质为主要限制性因子。 Soil fertility of citrus industry in Danjiangkou reservoir area of ​​Hubei Province was evaluated. The fertility factors such as pH value, organic matter, total nitrogen, available nitrogen, total phosphorus, available phosphorus and available potassium were selected, and then the value of each property was graded and standardized. The soil fertility was evaluated comprehensively by using modified Nemerow index. The results showed that the mass index of soil productivity in citrus industry was a general level of fertility, with alkali-hydrolyzable nitrogen and organic matter as the main limiting factors.
