为均衡提升山东省烟叶质量整体水平,进一步优化山东省烟草种植布局,本研究采集了济南、青岛和淄博烟区耕层土壤样品共 198 份,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,3 个市土壤烟草种植适宜性指数范围为 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 3 个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,存在的问题也不同,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.
In order to evenly improve the overall quality level of tobacco leaves in Shandong Province and further optimize the tobacco planting layout in Shandong Province,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 value,organic matter,alkaline nitrogen,available phosphorus,available potassium,chloride ions,available sulfur and total amount of water-soluble salts),and the weights were determined through principal component analysis.The comprehensive evaluation index of tobacco planting suitability was calculated and evaluated.The results showed that the soil suitability index for tobacco planting in 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 planting was 51.5%,while the proportion of just suitable samples was 36.9%,indicating that tobacco planting in the three cities had great development potential.There were differences in soil physical and chemical indicators and tobacco planting suitability among regions,and the problems were also different.Targeted improvement measures could be adopted to improve soil tobacco planting suitability and leaf quality.
