摘　　要：【目的】优化三七施肥技术,保护三七产区生态环境,为推动三七产业发展提供理论和实践依据。【方法】通过化肥减量田间试验,比较分析了不同处理对种植土壤养分变化及三七的农艺性状、产量、养分吸收和皂苷含量的影响。【结果】3年生三七种植区土壤肥力为丰富水平,减量施肥没有造成三七产量与品质的降低,处理C1农艺性状显著优于处理CR、处理CK。处理C1、处理C2皂苷含量显著高于处理CR与处理CK。综合比较,处理C1更适宜3年生三七的生长发育。【结论】施肥过多或不足均会影响三七的生长,在追肥过程中应注重施肥量的控制,适量施肥。【Objective】In order to provide theoretical and practical basis for promoting the development of the Panax industry,the fertilization technology of Panax Notoginseng was optimized.【Method】The effects of different treatments on soil nutrients,agronomic traits,yield,nutrient absorption and saponin content of Panax notoginseng were compared and analyzed through the field experiment of reducing fertilizer application.【Result】The soil fertility in the planting areas of Panax notoginseng was rich,and the yield and quality of Panax notoginseng were not decreased by reducing fertilization.The agronomic traits of C1 was significantly better than that of CR,CK.The saponin contents of C1 and C2 were significantly higher than that of CR and CK.On the whole,C1 was more suitable for the growth and development of Panax notoginseng.【Conclusion】Excessive or insufficient fertilization will affect the growth of Panax notoginseng,and the amount of fertilizer should be controlled in the process of topdressing.
