植物促生菌提高中草药品质的研究进展

Research Progress of Improvement of Chinese Herbal Medicines Quality by Plant Growth-promoting Bacteria

药用植物作为中医药产业原材料, 是行业的源头, 药用植物在生长发育过程中受到气候、环境等许多因素影响。近年来, 随着植物圈 (包括: 根际和叶际) 微生物及其与植物相互作用的深入研究, 为提升药用植物有效成分含量和中草药的品质提供了新思路和新方法。近年来, 以植物促生菌为主要功能菌的微生物肥料对药用植物的生长发育、中草药的品质提升等方面的研究报道越来越多, 主要是关于微生物肥料增加药用植物的产量、提高药用植物株生物量等的研究, 而有关药用植物根际和叶际微生物的多样性, 以及植物促生菌影响药用植物次生代谢产物积累的相关研究报道较少。本文重点综述了植物促生菌对药用植物根际微生物的影响, 植物圈微生物与药用植物的相互作用, 以及药用植物有效成分积累的研究进展; 并对植物圈微生物群落调控, 提高药用植物的健康和中草药产品质量提出了建议。

As the raw material of traditional Chinese medicine industry, medicinal plants are the source of the industry. Medicinal plants are affected by many factors such as climate and environment in the process of growth and development. In recent years, with the in-depth study of microorganisms in the phytosphere (including rhizosphere and phyllosphere) and their interactions with plants, new ideas and methods have been provided for improving the content of active ingredients in medicinal plants and the quality of Chinese herbal medicines. In recent years, more and more studies have been reported on the effects of microbial fertilizers with plant growth-promoting bacteria as the main functional bacteria on the growth and development of medicinal plants and the quality improvement of Chinese herbal medicines. It is mainly on the research of using microbial fertilizers to increase the yield of medicinal plants and increase the biomass of medicinal plants. However, there are few reports on the diversity of rhizosphere and phyllosphere microorganisms of medicinal plants and the effects of plant growth-promoting bacteria on the accumulation of secondary metabolites of medicinal plants. In this paper, the effects of plant growth-promoting bacteria on rhizosphere microorganisms of medicinal plants, the interaction between microorganisms in phytospheres and medicinal plants, and the research progress on the accumulation of active ingredients in medicinal plants were reviewed. Suggestions were put forward for the regulation of microbial community in plant circle, improving the health of medicinal plants and the quality of Chinese herbal medicine products.
