对湖北省恩施州魔芋种植基地土壤肥力质量进行了评价。选取pH值、有机质、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,采用修正的内梅罗公式对采样区域的土壤生产力质量进行评价。评价结果:魔芋种植基地土壤生产力质量指数属肥力一般水平,有机质为主要限制性因子。表明土壤整体肥力较低,限制了魔芋生长,在生产中需注意土壤肥力更新及可持续利用。
Soil fertility quality of konjac planting base in Enshi Prefecture of Hubei Province was evaluated. The fertility factors such as pH value, organic matter, alkaline hydrolysis nitrogen, total phosphorus, available phosphorus, available potassium and so on were selected, and then the value of each attribute was graded and standardized. The modified soil neoclassical formula was used to evaluate the soil productivity in sampling area. Evaluation results: The quality index of soil productivity of konjac planting base belongs to the general level of fertility and the organic matter is the main limiting factor. This indicates that the overall soil fertility is low, which limits the growth of konjac. In the production, soil fertility should be updated and the sustainable use should be taken.
