| 摘 要： | 了解土壤肥力对烟田土壤保育具有积极的指导意义。本研究采集了四川攀西山区4个代表性植烟县(区)的19个典型烟田耕层样品,测定了对烤烟产质量影响大且能反映土壤肥力的指标,利用模糊综合评价法计算了土壤肥力综合肥力指数(IFI)。结果表明：19个烟田耕层土壤的pH、有机质、全氮、碱解氮、有效磷、有效钾和水溶性氯含量平均值分别为6.25、21.6 g/kg、1.28 g/kg、120.61 mg/kg、42.84 mg/kg、148.69 mg/kg和7.47 mg/kg,适宜的植烟烟田比例分别为52.67%、26.32%、36.84%、42.11%、36.84%、84.21%和21.05%。烟田土壤肥力综合评价指数介于0.30～0.87,平均为0.55,总体上处于较高水平。施肥上应注意多施钾肥和磷肥并提高其利用率,对氯素低的烟田(<10 mg/kg)可以酌情施用氯肥。

| Abstract: | The characteristics of soil nutrients play important roles in the improvement of soil fertility and quality as well as the tillage system. In this study, the topsoil samples from were collected from 19 typical tobacco-planting fields in 4 representative tobacco-planting regions in Panxi Mountainous region of Sichuan province, the main indicators of soil fertility were determined, and the soil integrated fertility index (IFI) were calculated by fuzzy comprehensive assessment method. The results showed that the average contents of pH, SOM, total nitrogen, alkaloid nitrogen, available phosphorus, rapidly available potassium and water-soluble chlorine of the soil samples were 6.25, 21.6 g/kg, 1.28 g/kg, 120.61 mg/kg, 42.84 mg/kg, 148.69 mg/kg and 7.47 mg/kg, respectively; The proportions of suitable tobacco fields were 52.67%, 26.32%, 36.84%, 42.11%, 36.84%, 84.21% and 21.05%, respectively. The IFI ranged from 0.30 to 0.87 with an average of 0.55, which was generally at a high level. Attention should be paid to applying more phosphorus and potassium and promoting their utilization rates, and chlorine fertilizer could be applied cautiously for the tobacco-planting fields with low water-soluble chlorine content (<10 mg/kg). |
