摘要:

在设施农业的大背景下,连作障碍普遍存在于粮食作物、经济作物、蔬菜、林木及中药材等各种植物中,严重制约了种植业的可持续发展。大量研究表明自毒作用是导致重茬连作障碍的主要原因之一,系统介绍了自毒物质的来源和种类、作用特点及机理,概述了自毒物质的提取、活性检测、降解功能菌株分离筛选等研究方法,系统归纳了土壤改良、耕作模式改良、生物防治等消减连作障碍的措施,并提出了现有研究中存在的问题和今后发展重点,为自毒作用的深入研究提供新思路。

关键词: 连作障碍, 自毒物质, 自毒作用

Abstract:

Under the background of facility agriculture, replant disease is widespread in grain crops, such as food crops, cash crops, vegetables, trees, Chinese herbal medicines and other plants, which seriously restricts the sustainable development of planting industry. A large number of studies have confirmed that autotoxicity is one of the main causes of replant disease, so the paper systematically introduced the sources, types, characteristics and mechanism of autotoxicity, summarized research methods such as extraction of autotoxic substances, activity detection, isolation and screening of functional degradation strains, and analyzed the abatement measures such as soil improvement, cultivation mode improvement, biological control and others. As well as, the problems existing in the research and development research emphasis in the future were putted forward. It would provide reference for the in-depth study of replant disease and technical support for the green and healthy development of facility agriculture.

Key words: replant disease, autotoxins, autotoxicity
