运用计算机对暗紫贝母生长区的土壤元素进行主分量分析(PCA排序),将暗紫贝母生长区的土壤初步确定为若尔盖高原土壤区和茂汶土壤区.研究表明,土壤元素K、Mn、Zn、P的含量差异是产生松贝(川贝母)品质差异的重要因子.文中指出若尔盖高原土壤区所产松贝为最优的商品规格.
Computerized principal component analysis (PCA sorting) of soil elements in the growing area of Fritillaria purpurea was used to determine the soil in the growing area of the Fritillaria purpurea as Ruoergai plateau soil area and Maowen soil area. Studies have shown that the soil element K, The difference in the contents of Mn, Zn, and P is an important factor in producing the quality difference of Fritillaria cirrhosa. The paper points out that the production of pine oysters in the soil area of Zoige Plateau is the best commercial specification.
