| 目的：明确遂宁川白芷产地形成、迁徙原因，研究产地迁徙过程中土壤质地改变对川白芷药材质量的影响。方法：通过文献考察和实地调查探明川白芷种植环境、历史及近况。采用土壤比重计测定土壤沙粒、粘粒和粉粒的占比，并依据国际制土壤质地分类标准判定土壤质地类型。采用高效液相色谱法（HPLC）测定氧化前胡素、欧前胡素、异欧前胡素3个香豆素成分的含量。基于灰色关联度法探索土壤质地参数（沙粒、黏粒和粉粒占比）和白芷药材质量指标的关联性。结果：川白芷原产地主要分布于涪江流域附近，已有数百年种植历史，近年由于各种原因种植面积大幅减少，新产地迁徙至丘陵、山坡等地。不同乡镇土壤质地差异明显，涪江流域附近壤土居多，丘陵、山坡等地黏土居多；渔舟村(CBZ-1)、洪龙村(CBZ-4)的药材主根长、侧根较少，但香豆素类成分含量较低；太乙镇(CBZ-5)、余建村(CBZ-6)的药材则相反。灰色关联度结果显示土壤质地参数、药材性状指标及香豆素含量三者之间均具有关联性，粉粒占比与药材各项指标关联度均较高（＞0.600）；其次为黏粒，氧化前胡素与药材主根长度、主根重量和主根直径关联度最强（＞0.700），欧前胡素和异欧前胡素次之。结论：遂宁川白芷产地正在迁徙，土壤质地变化明显且对川白芷药材品质影响明显，是迁徙过程中值得注意的要素。 |
| English Summary: |
| To clarify the reasons for the origin and migration of the cultivation area of Sichuan Angelica dahurica in Suining and to study the impact of changes in soil texture during origin variation on the quality of Sichuan A.dahurica medicinal materials.Methods:Through literature review and field investigations，the cultivation environment，historical background，and recent developments of Sichuan A.dahurica were explored.The soil texture was analyzed by determining the proportions of sand，clay，and silt using a soil hydrometer，and classified according to international soil texture standards.The content of three coumarins(oxypeucedanin，imperatorin，and isoimperatorin) was determined using high-performance liquid chromatography(HPLC).The correlation between soil texture parameters(sand，clay，and silt proportions) and Sichuan A.dahurica quality indicators was explored using the grey relational analysis method.Results:The original cultivation area of Sichuan A.dahurica was mainly distributed around the Fujiang River basin，with a cultivation history of several hundred years.In recent years，due to various factors，the cultivation area has significantly decreased，and new planting sites have migrated to hilly and sloped regions.The soil texture varied significantly across different towns，with loam soils predominantly found around the Fujiang River basin，while clay soils were more common in hilly and sloped areas.In Yuzhou Village(CBZ-1) and Honglong Village(CBZ-4)，the main roots of the medicinal material were long with fewer lateral roots，but the content of coumarins was relatively low.In Taiyi Town(CBZ-5) and Yujian Village(CBZ-6)，the opposite pattern was observed.The grey relational analysis showed a significant correlation between soil texture parameters，the physical traits of the medicinal materials，and coumarin content.The silt proportion had the highest correlation with the quality indicators of Sichuan A.dahurica(correlation>0.600)，followed by clay.Oxypeucedanin had the strongest correlation with main root length，weight，and diameter(correlation>0.700)，while imperatorin and isoimperatorin had slightly lower correlations.Conclusion:The cultivation area of Sichuan A.dahurica in Suining is undergoing migration，with significant changes in soil texture that have a clear impact on the quality of the medicinal materials.Soil texture is an important factor to consider during the migration process. |
