从改良土壤角度探索人参连作障碍解决方法的研究进展.

The unique black soil resources and natural environment of Jilin province provide the proper conditions for the growth of ginseng-the king of herb. Ginseng industry has effectively promoted the development of medical and health industry, and brought considerable economic income for ginseng farmers. However, long-term continuous cropping of ginseng causes the chemical, biological, and physical properties deterioration of soil, which influences the yield and the quanlity of ginseng, and results in the occurrence of replant obstacle. Identifying the malignant soil factors in continuous cropping obstacles, then analyzing the evolution process, and putting forward the improvement strategies is the primary task of ginseng research at present. This paper reviews the influence of ginseng cultivation on the physicochemical property, nutrient, enzyme activity, microecology and ecotoxicity of the soil, and the achievements of improving ginseng soil by chemical and biological techniques and methods in recent 10 years.
