林木根系分泌物的化感作用

目前关于根系分泌物的研究更多地是关注其与微生物间关系，而对化感方面缺乏系统全面的认识。近年来林木的化感作用逐渐成为研究热点。文中通过深入分析国内外关于林木化感作用研究，归纳总结了根系分泌物的种类、释放途径及作用特点，从化感作用的角度深刻揭示根系分泌物，指出现有研究中存在的问题并对未来的研究加以展望，以期为解决林木混交及连栽地力衰退问题提供理论参考，为实现森林可持续经营提供借鉴。

Allelopathy of Tree's Root Exudates

The studies on root exudates currently pay more attention to its relationship with microorganism, and lack the comprehensive understanding of allelopathy.In recent years allelopathy of trees has become the research hotspot.In this paper, studies on allelopathy of tree' s root exudates were reviewed to summarize the types, releasing approach and effect of root exudates and to help readers know root exudates more deeply from the perspective of allelopathy.Problems in existing studies and future development were pointed out.It was expected to provide reliable theoretic basis to solve the problems of soil fertility declining in mixed forests and in continuous cropping forests, so as to achieve sustainable forest development.
