Abstract: By optimizing and selecting the minimum dataset(MDS)to maximize the characterization of soil fertility quality,this study aims to explore the ecological relationship between soil fertility quality and the formation of Ligusticum chuanxiong quality,in order to improve soil quality and achieve high⁃quality cultivation of Ligusticum chuanxiong. Ligusticum chuanxiong and rhizosphere soil were collected from 114 sampling points in 38 plots in Meishan,Pengzhou,Qionglai,and Shifang cities in Sichuan Province.The content of 21 soil indicators and 5 effective component indicators was measured,and the Ligusticum chuanxiong comprehensive quality index(AQI)and soil fertility quality index(SQI)were calculated.The results showed that the selected MDS contained six indexes of nitrate nitrogen,available phosphorus,available magnesium,available iron,available cadmium and total iron content,with a cumulative contribution rate of 81.83%.There were significant differences in soil fertility quality among the four cities.The comprehensive index score of soil fertility quality for Ligusticum chuanxiong in Pengzhou was the highest,at 0.53,while that for Meishan was the lowest,at 0.34;The comprehensive quality index of Ligusticum chuanxiong in Pengzhou was also the highest,at 0.46.The correlation analysis between the comprehensive index of soil fertility quality and soil indicators showed that the content of available phosphorus,available iron,nitrate nitrogen,and total iron were important factors for improving soil fertility quality. Combined with the redundancy analysis results,the content of available phosphorus and available iron was a key factor affecting the formation of Ligusticum chuanxiong quality and soil fertility quality.In summary,a soil fertility evaluation system for Ligusticum chuanxiong has been established based on MDS. The high⁃quality planting process of Ligusticum chuanxiong requires key regulation of available phosphorus and available iron content in the soil.

摘要: 通过优化筛选最小数据集(MDS)最大限度表征土壤肥力质量,探究土壤肥力质量与川芎品质形成之间的生态联系,以改良土壤及实现川芎高质量种植。采集四川眉山、彭州、邛崃、什邡四市的38个样地114个样点的川芎和根际土壤,测定21个土壤指标以及5种有效成分指标含量,并计算川芎品质综合指数(AQI)与土壤肥力质量综合指数(SQI)。结果表明,筛选得到的MDS包含硝态氮、速效磷、有效镁、有效铁、有效镉、全铁含量6个指标,累计贡献率为81.83%;四市土壤肥力质量存在较大差异,彭州的川芎土壤肥力质量综合指数得分最高,为0.53,眉山土壤肥力质量综合指数得分最低,为0.34;彭州川芎品质综合指数得分亦最高,为0.46;土壤肥力质量综合指数与土壤指标相关性分析结果表明,速效磷、有效铁、硝态氮、全铁含量为提高土壤肥力质量的重要因子,结合冗余分析结果,速效磷、有效铁含量是影响川芎品质形成和土壤肥力质量的关键因子。综上所述,基于MDS建立了川芎土壤肥力评价体系,川芎高质量种植过程需要重点调控土壤中速效磷、有效铁含量。
