| 摘 要： | 为了准确评价云南省靖西市植烟土壤养分现状,在该市10个植烟乡镇采集206个土壤样品,选取pH、有机质、碱解氮、速效磷、速效钾、有效硫、有效锌和水溶性氯8个评价指标,运用隶属度函数模型、指数和法和克里金插值法对靖西市烟区土壤肥力进行适宜性评价。结果表明,采样区土壤肥力均在Ⅴ级以上,适宜性指数为0.54,肥力中等偏下;10个乡镇中,壬庄肥力适宜性等级最高,其他依次为同德、化峒、新靖、渠洋、岳圩、地州、新甲、禄峒和武平。其中壬庄南部肥力最高,同德南部和渠洋东北部肥力较高,岳圩北部部分区域肥力较高;新靖土壤肥力均为中等肥力;地州中部肥力偏低,四周肥力高;禄峒肥力整体偏低;武平肥力最低且北部极低。根据土壤养分丰缺现状、绘制土壤肥力等级空间分布图,为该区烟草科学施肥提供了依据。

| Abstract: | To accurately evaluate the nutrient status of tobacco-planting soil in Jingxi city, Yunnan province, 206 soil samples were collected from ten tobacco-planting towns in the city and eight indexes (pH, organic matter, alkali-hydrolyzable as evaluation indicators nitrogen, available P, available K, available S, available Zn, and water-soluble Cl), as evaluation indicators.The suitability of soil fertility in the tobacco area of Jingxi was evaluated by using the membership function model, index sum method, and Kriging interpolation method using eight evaluation indicators. The results showed that the soil fertility of all the sampling sites were above grade V, the suitability index was 0.54, and the fertility was moderately low; among the 10 townships, Renzhuang had the highest fertility suitability grade, followed by Tongde, Huadong, Xinjing, Quyang, Yuexu, Dizhou, Xinjia, and Ludong, while Wuping had the lowest fertility. The southern of Renzhuang had the highest fertility, while the southern of Tongde had higher fertility; the northeastern of Quyang had higher fertility; the northern of Yuexu and Xinjing had medium fertility soil fertility; the middle part of Dizhou had lower fertility, the surrounding fertility was high; the overall fertility of Ludong was low; Wuping had the lowest fertility and extremely low in the north. According to the current situation of soil nutrient abundance and deficiency, the spatial distribution map of soil fertility grade was drawn, which provides a basis for scientific fertilization of tobacco production in this region. |
