| 中文摘要: |
| 中医是我国特有的传统文化和产业，优质中药材是关系国计民生的战略性资源。近年来随着国内
外对中药材需求的日益增长，人工栽培药用植物的种类和面积大幅增加，由于耕地有限、种植条件及道地性等
因素的限制，在药用植物集约化种植过程中，普遍存在严重的连作障碍问题，在以块根类入药的药用植物上表
现尤为严重。目前连作障碍已经成为制约中药材产量和品质的关键因素，严重阻碍中药材规范化种植和产业化
发展。从药用植物连作障碍危害、形成机理以及调控措施的最新研究进展进行总结，指出连作障碍问题主要是
植物 - 土壤 - 微生物三者共同作用的结果，分析了当前药用植物连作障碍形成的 3 个主要原因，包括土壤养分
亏缺和失衡、化感自毒作用以及根际微生态破坏导致土传病害加重。提出了连作障碍的调控措施，包括优良品
系选育、土壤灭菌、建立合理的耕种制度、施用微生物菌肥，并对未来研究的方向和重点进行了探讨，以期为
克服药用植物连作障碍的栽培管理提供科学参考。 |

| Traditional Chinese medicine（TCM）is a unique traditional culture and industry in China and excellent
Chinese medicinal materials are strategic resources related to people’s livelihood. In recent years, with the increasing
demand for Chinese medicinal materials at home and abroad, the types and areas of artificially cultivated medicinal plants
have increased greatly. Due to the limitations of cultivated land, planting conditions and authenticity, serious continuous
cropping obstacles commonly exist in the intensive cultivation of medicinal plants, especially in the medicinal plants
with tuberous roots as medicine. At present, continuous cropping obstacle has become the key factor restricting the yield
and quality of medicinal materials, and seriously hindered the standardized planting and industrialization development of medicinal materials. In this review, the latest research progresses on the damage, formation mechanism and control
measures of continuous cropping obstacles of medicinal plants were summarized and it was pointed out that the continuous
cropping obstacle problem was mainly the result of combined effect of plant - soil - microbial. The causes of continuous
cropping obstacles of medicinal plants were analyzed, which mainly included three aspects, namely, soil nutrient deficiency
and imbalance, allelopathic autotoxicity and the aggravation of soil-borne diseases caused by destruction of rhizosphere
microecology. The control measures of continuous cropping obstacles were put forward, including selection of excellent
strains, soil sterilization, establishment of reasonable farming system, application of microbial fertilizer. The direction and
key points of future research were discussed in order to provide scientific references for the cultivation and management of
medicinal plants to overcome continuous cropping obstacles. |
