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.
间作种植系统是中国传统农业的精髓之一，也是现代生态种植最常见、最基本的模式之一。间作系统利用物种多样性原理，创造合理的种间相互作用条件，具有明显的生产力优势。本文从空间视角将种间相互作用分为地上部分和地下部分，并阐述其对药用植物产量和次生代谢产物的影响及机制。地上部分的种间相互作用主要介绍植物间空间资源的分配与利用。地下部分的种间相互作用主要介绍土壤根际效应及相关介导因子、根系分泌物、土壤微生物、根际空间结构和土壤环境因子。在了解种间相互作用机制的基础上，本文以有效防治病虫害、提高药材产量和改善药材质量为效益指标，进一步探讨间作在中药生态农业中的应用，以期寻求间作更好的优势，为间作生产模式在中药生态农业中的利用提供思路。
