应用等离子体发射光谱仪对无土与土壤栽培的西洋参根进行微量元素分析,并对微量元素的含量进行了比较,无土栽培品的微量元素含量与土培品差异不大,可疑有害元素均未检出。 Trace element analysis of American ginseng rootless and soil cultivated by soilless and soil was carried out by using a plasma emission spectrometer, and the contents of trace elements were compared. The difference between trace element content in soilless cultures and soil culture products was not significant, and no suspicious harmful elements were found. Check out.
