目的 研究积雪草Centella asiatica人工种植技术。方法 以积雪草产量及药材中积雪草苷和羟基积雪草苷的总量为评价指标,考察土壤类型、种植密度、基肥、施肥方式及荫蔽度等不同因素对种植效果的影响。结果 积雪草适合种植于泥炭土-珍珠岩(1∶1)中,种植密度为20 cm×20 cm,基肥为有机肥/复合肥(1∶1),基肥用量为7.5 g/m2,定植4个月后施尿素(18 g/m2)、5个月后施复合肥(45 g/m2),适宜荫蔽度为75%。结论 本实验研究可为建立积雪草GAP种植基地奠定基础。

Objective To study the artificial planting technique of Centella asiatica. Methods The yield and the total content of asiaticoside and madecassoside in C. asiatica were used as evaluating indicators. And the influences of different factors such as soil type, planting density, base fertilizer, fertilization, and shading degree on planting effect were investigated. Results C. asiatica was suitable to be planted in peat soil/perlite (1︰1), the planting density was 20 cm × 20 cm, the base fertilizer was organic fertilizer/compound fertilizer (1︰1) and its consumption was 7.5 g/m2, urea (18 g/m2) was applied after 4 months and compound fertilizer (45 g/m2) was applied after 5 months, the appropriate shading degree was 75%. Conclusion The research results could be used to establish the GAP planting base of C. asiatica.
