摘要: 采用隶属度函数模型、因子分析法、模糊数学综合法评价云南省丽江市烟区2015—2020年土壤养分丰缺、肥力适宜性变化状况,以期为烟区科学合理施肥、烟区规划、植烟面积调整提供依据。结果表明,土壤pH、氮含量呈增加趋势,适宜等级占比下降;有机质、速效钾含量减少,适宜等级占比呈下降趋势;活性氯含量降低,适宜等级占比增加;有效磷含量下降,适宜等级占比变化不大;有效硫偏高且适宜等级占比降低;烟区土壤肥力适宜性下降。在烟草种植中,应遵循减氮、控磷、提钾、减硫,少氯、重施有机肥、少施碱性肥料的施肥原则,配套合理耕作制度,充分利用土壤资源,提高烟叶产量和品质,实现烟叶生产可持续发展。

Abstract: Membership function model, factor analysis method and fuzzy mathematics comprehensive method were adopted to evaluate soil nutrient abundance and fertility suitability in Lijiang City tobacco areas of Yunnan Province from 2015 to 2020 to provide a basis for scientific and reasonable fertilization, tobacco area planning, and tobacco planting area adjustments. The results showed that pH and nitrogen content showed an increasing trend, while the suitable ratio decreased; the organic matter and available potassium content decreased, while the suitable ratio showed a downward trend; the active chlorine content decreased, and the suitable ratio increased; the available phosphorus content decreased, and the suitable ratio did not change; the available sulfur was high and the suitable ratio decreased; the soil fertility suitability of the tobacco area decreased. In tobacco planting, it was necessary to follow the fertilization principles, such as reducing nitrogen, controlling phosphorus, increasing potassium, reducing sulfur, reducing chlorine, reapplying organic fertilizers, and applying less alkaline fertilizers, support a reasonable farming system, make full use of soil resources and improve tobacco production and quality, to realize the sustainable development of tobacco production.

Key words: tobacco, soil fertility, comprehensive evaluation, Lijiang City
