Research advances on allelopathy of Cunninghamia lanceolata plantation

人工林地力衰退是国内外学者长期关注的问题,杉木人工林连作出现了显著的地力衰退现象,严重影响了杉木人工林的可持续经营。化感作用是杉木人工林地力衰退的重要原因之一,文章回顾了杉木人工林化感作用的研究历史,重点对近年来杉木人工林的化感物质、释放方式、作用机理与化感效应研究进行了总结,提出杉木人工林化感作用今后的研究重点,以期引起相关学者的关注,为解决长期困扰杉木人工林可持续经营的难题提供研究思路。

The land capacity decline is a problem which has been payed long-term attention in the world. The area of plantation in China is the most in the world. The land capacity declining phenomena had appeared in Cunninghamia lanceolata plantation, which badly influenced the sustainable management of plantation. Allelopathy was one of the most important reasons of land capacity decline of Cunninghamia lanceolata plantation.On the basis of correlative documents, the article retrospected the research history on this problem at home and abroad. Mainly, this article put high emphasis on the research advances of plantation allelopathy risen in recentyears, and put forwardwith key contents and problemswhich should be studied in the future in order to draw some scholars＇attention.At the same time, the authors wish to offer some research thoughts to overcome this science difficulty which longly puzzled the plantation management.
