间套作体系下种间互作对药用植物影响的研究进展

Research progress in effects of interspecific interaction on medicinal plants in intercropping system

间套作耕作体系是我国传统农业的精髓之一,也是现代生态种植最常见的基本模式之一。间套作体系运用物种多样性原理,创造合理的种间互作条件,表现出明显的生产力优势。该文从空间角度将种间互作分为地上部分和地下部分,阐述了其对药用植物产量及次生代谢产物的影响及机制。地上部分种间互作以种间资源在植物间的分配利用为主,地下部分重在对种间互作中的土壤根际效应及相关的介导因子根系分泌物、土壤微生物、根系空间构造、土壤环境因子进行分析。在了解种间互作机制的基础上,该文进一步探讨了间套作在中药生态农业中的应用,以病虫害有效防治、药材产量增加、药材品质提升作为效益指标,寻求更佳的间作优势,为中药生态农业中对间套作生产模式的利用提供思路。

Intercropping farming system is one of the essence of traditional agriculture in China and one of the most common and basic patterns of modern ecological planting.Intercropping system uses the principle of species diversity to create reasonable interspecific interaction conditions with obvious productivity advantages.In this paper,the interspecies interaction is divided into aboveground and underground parts from the space view,and its influence and mechanism on the yield and secondary metabolites of medicinal plants are elaborated.The interspecific interaction in the aboveground part mainly introduces the distribution and utilization of space resources among plants.The interspecific interaction in the underground part mainly introduces the soil rhizosphere effect and related mediating factors,root exudates,soil microorganisms,root space structure and soil environmental factors.On the basis of understanding the mechanism of interspecific interaction,this paper further discusses the application of intercropping in traditional Chinese medicine ecological agriculture,taking the effective control of diseases and insect pests,the increase of medicinal material yield and the improvement of medicinal material quality as the benefit index,so as to seek better advantages of intercropping and provide ideas for the utilization of intercropping production mode in traditional Chinese medicine ecological agriculture.
