摘要
喜旱莲子草Alternanthera philoxeroides是全球性恶性入侵杂草,近年来在中国已呈蔓延之势,对经济及生态环境造成严重破坏。整理了近年来对喜旱莲子草的相关研究,从其生物学特性和对环境的利用能力等方面对喜旱莲子草的入侵机制进行阐述,表明该植物的形态、繁殖以及表型可塑性和适应性等特征,有助于其成功入侵,并在入侵地形成单优势种群。还从物理、化学、生物、生态防治等4个方面对其防治策略进行分析,针对其入侵机制与防治研究中存在的问题提出了相应建议:加强采用土壤动物和土壤微生物的方法开展该入侵植物的生物防治研究,同时开展替代控制的生态控制策略探索实践。
Alternanthera philoxeroides is a global malignant invasive weed. It has shown a tendency to spread and cause severe damage to economic and ecological environment in China. This paper reviewed the recent researches on the invasion of A. philoxeroides, elaborated its invasion mechanism from biological characteristics and its ability to exploit environment, indicating the characteristics of its morphology, reproduction, phenotypic plasticity and adaptability contribute to its successful invasion, and form a single dominant populations in the invaded area. The research analyzed the prevention strategy from four aspects including physics, chemistry, biology and ecology, and put forward the respective recommendations for the existing problems in the research on invasion mechanisms and prevention： strengthening the use of soil animals and soil microbial biological control methods to carry out the biocontrol research on invasive plants, while carrying out exploration and practice of ecological alternative control strategy.
