摘　　要：目的分析种植三七土壤及植株残体挥发性成分,为研究三七化感效应,解决连作障碍提供依据。方法采用GC-MS分析种植三七后不同年限土壤及三七植株残体挥发性成分。结果从种植三七土壤、三七须根和茎叶降解物中都分离得到26个挥发性成分。结论三七土壤及植株残体挥发性成分中含有较高的邻苯二甲酸二异丁酯等化感物质,是导致三七产生化感作用的重要原因。Objective Analyze volatile components in planting soil and crop residues ofPanax notoginseng, to research it＇s allelopathic effect and provide basis for solving continuous cropping obstacle. Methods GC-MS was used to analyze volatile components in planting soil and crop residues of Panax notoginseng after different period. Results 26 volatile compounds were isolated from the planting soil ofPanax notoginseng and it＇s fibrous root, stem and leaf degradation. Conclusion Planting soil and crop residues of Panax notoginseng contained massive allelopathic substance such as diisobutylphthalate is the important reason which lead to allelopathy.
