旧参地重复利用问题的地球化学研究

The geochemistry research on re-utilization of the old ginseng ground

在靖宇县第一参场采集了人参、土壤 (包括原始土壤、参地土壤、旧参地土壤 )及玄武岩样品 ,测试了与植物生长关系密切的 2 0种化学元素 ,系统地研究了人参生长的生态环境、地球化学环境 ,总结出该区玄武岩、原始土壤、参地土壤、旧参地土壤及人参中化学元素的分布特征、变化规律及其影响因素 ,从而查明了导致旧参地荒废的地球化学原因 ,提出了改良和重复利用旧参地的方案。

In the field of Jingyu County No 1 ginseng Farm,we took some samples of the soil (include the primitive soil,ginseng ground soil and soil of old ginseng ground) and basaltic rocks,made a test of plant relatively closely with 22 types of chemical elements Meanwhile,have a research on ecological environment for ginseng growing,agrochemical background and its characteristics And finally summed up the characteristics of chemical element of the basalt,primitive soil,ginseng ground soil and ginseng,and their variety regulation etc Thus,we found out geochemical factors,which make the old ginseng ground into the uncultivated land and make the proposals on the project of the old ginseng ground,i e how to improve and use them again
