　　根系分泌物是植物根系释放到根际环境中的有机物质的总称，对土壤结构形成、土壤养分转化、植物养分吸收、土壤微生物分布、环境胁迫缓解等方面都具有重要作用。但是，由于土壤中微生物对根系分泌物的降解以及根系分泌物本身含量低、成分复杂，根系分泌物的研究方法一直是植物营养学与土壤科学的研究热点和难点。近年来，一些新的实验技术和研究方法被应用到对植物根系分泌物的研究中。本文对目前在根系分泌物研究中应用较多的以及新发展起来的各种收集、分离和鉴定方法进行了综述，希望有助于相关研究者在针对不同的研究对象和目的时选择出可行、合适、高效的根系分泌物研究方法和技术。

Root exudate is a general term for a group of organic compounds released from the plant roots to rhizo-sphere, and plays an important role in formation of soil structure, transformation of soil nutrients, absorption of nu-trients by plants, distribution of soil microbe, alleviation the environmental stress, and so on. Furthermore, owing to the degradation by the soil microbe as well as the low concentration and complex composition nature of itself, root exudate and its research methods are always the hot spots and challenges. Recently, several novel experimental tech-niques and research methods have been developed and applied in the research on root exudates. In this paper, the collection, separation, purification and identification of root exudates are reviewed, which will be helpful to re-searchers to choose a feasible, suitable and efficient method to their certain object and purpose.
