吉林省作为人参的主产区,其产量的增减将直接影响着全国的人参产品加工情况,所以针对产地栽参土壤的研究是十分必要的。研究结果表明,多年栽参的土壤环境质量正呈现下降趋势,土壤受环境的影响越来越严重,尤其是土壤酸化问题日渐突出。所以就老参地土壤酸化以及改良进行了分析,以期对酸化土壤的治理提供科学的理论依据。 As the main producing area of ​​ginseng in Jilin Province, the increase and decrease of its output will directly affect the processing of ginseng products throughout the country. Therefore, it is necessary to study the planting soil of ginseng origin. The results showed that the environmental quality of soil planted for many years was showing a downward trend, and the soil was more and more affected by the environment. Especially, the problem of soil acidification became increasingly prominent. So we analyzed the soil acidification and the improvement of the old ginseng so as to provide a scientific theoretical basis for the treatment of the acidified soil.
