摘　　要：试验以人参根际土壤提取物处理新森林土,研究了根际化感作用及其对种子萌发的影响。结果表明:参地土壤中含有促进人参病害发生和抑制人参生长的自毒性物质,造成人参发芽率、种子酶活性、根系生活力降低,发病率提高,从而形成人参生长障碍。By treating new forest soil with extracts from ginseng rhizosphere soil, allelopathy of the ginseng soil and its effect on seed development were studied. The result shows that there is self-tonic material in the ginseng soil which can inhibit ginseng growth and promote ginseng disease happening. All of these can reduce ginseng germination, enzyme activity of seed and activity of mot system, increase the incidence of disease, and thus inhibit the growth of ginseng.
