摘要
文章以全球普遍关注的外来植物入侵为背景,综述了外来入侵植物化感物质与土壤化学性质(土壤pH,土壤有机碳和有机质,土壤中的化学元素等)、土壤生物群落(土壤微生物、土壤动物)的关系。并探讨了未来研究需要加强的几个方面,包括将化感作用与野外实际情况相结合研究,更真实的反映田间状况;进一步探讨微生物在化感物质生物变化过程中的作用及其机理;化感物质作为信号物质如何影响微生物代谢,从而影响地上植物;深入研究化感作用与土壤之间的相互关系,为入侵植物生物防治的安全性提供理论指导等方面。
Based on the developments of globally-concerned exotic plant invasions, the research advances in interactions between allelochemicals and soil chemistry property, allelochemicals and soil biota arc reviewed. Considering the current researches domestically and abroad, the directions in the study on interactions between invasive plants allelopathy and soil are advanced in the end. The further research should focus on putting allelopathy study into field in order to reflect its real effect; investigating function of microbes in allelochemicals from invasive plants and clarifying the mechanism; making clear how allelochemicals work and consequently affect relative plants if allelochemicals are signals in microbial metabolism; providing guarantee for safety in invasive plants biocontrol through studying the interactions between allelopathy and soil.
