土壤的FTIR指纹图谱及中药材栽培的地域选择研究

Edaphic FTIR Finger Print and the Area Choice of Chinese Herb Culture

为了更深入地研究土壤,以利于中药材栽培的地域选择,采用简便、快捷、分辨率高的FTIR技术,对53份土壤样品进行比较研究,结果表明,土壤样品在3 621,3 425,1 642,1 435,1 029,878,760和690cm-1有共有峰;但其相对强度有别,此外还有1 796,2 982和2 874 cm-1的峰也有所不同,借此可以客观地区分不同地域的土壤。试验同时说明甘肃天水、定西等地的土壤状况与山西土壤相近。土壤的FTIR指纹图谱可以为中药材的移栽提供极有价值的信息,同时也可以很好地用于土壤的研究。

In order to search for the difference of the soil of Chinese herb growth, and provide useful information for the area choice of Chinese herb culture, 53 soil samples were detected by FTIR. The results showed that all the samples have 8 peaks at 3 621, 3 425, 1 642, 1 435, 1 029, 878, 760 and 690 cm^-1 , respectively, but the relative intensity is different. In addition, the peaks at 1 796, 2 982 and 2 874 cm^-1 show difference too. This can be used to distinguish soil in different area. The study also showed that soil in Tianshui and Dingxi of Gansu province are similar to that in Shanxi province. Conclusions ： FTIR finger print of soil can provide useful information for the area choice of Chinese herb culture and transplantation and can be used in the study of soil.
