山东烟草发展型产区土壤种植适宜性评价

为均衡提升山东烟叶质量整体水平,进一步优化山东烟草种植布局,本研究采集了济南、青岛、淄博烟区耕层198份土壤样品,采用模糊数学隶属度函数对土壤理化指标(pH值、有机质、碱解氮、有效磷、速效钾、氯离子、有效硫和水溶性盐总量)进行评价,并通过主成分分析法确定权重,计算烟草种植适宜性综合评价指数并进行了评价。结果表明,三地市土壤烟草种植适宜性指数范围0.33-0.87,平均值为0.59。烟草种植较适宜及高适宜样品占比为51.5%,尚适宜性样品占比为36.9%,说明三地市烟草种植具有较大发展潜力。区域间土壤理化指标和烟草种植适宜性存在差异,存在问题也不相同,可针对性采用改良措施,以提升土壤植烟适宜性和烟叶质量。

Evaluation of soil planting suitability in Shandong tobacco development-oriented areas

In order to balance and improve the overall quality level of tobacco leaves in Shandong and further optimize the tobacco planting layout in Shandong, this study collected 198 soil samples from the tillage layer of tobacco growing areas in Jinan, Qingdao, and Zibo. Fuzzy mathematical functions were used to evaluate soil physical and chemical indicators (pH, organic matter, alkaline nitrogen, available phosphorus, available potassium, chloride ions, available sulfur, and total amount of water-soluble salts), and the weights were determined using principal component analysis. The comprehensive evaluation index of tobacco planting suitability was calculated and evaluated. The results showed that the suitability index for tobacco cultivation in the soil of the three cities ranged from 0.33 to 0.87, with an average value of 0.59. The proportion of suitable and highly suitable samples for tobacco cultivation is 51.5%, while the proportion of suitable samples is 36.9%, indicating that tobacco cultivation in the three cities has great development potential. There are differences in soil physical and chemical indicators and tobacco planting suitability between regions, and there are also different problems. Targeted improvement measures can be adopted to improve soil tobacco planting suitability and leaf quality.
