自然环境中三叶草的生长特点及扩散能力分析

三叶草作为外来种引入我国后，主要分布在淮河以南和西南地区．主要用于建设草坪和作为饲料而培养．近年来，在吉林省野外也已发现三叶草的存在，并且长势旺盛，且呈不断扩散趋势，极有可能因强竞争力和强大的增殖能力而成为一种新型害草．通过对自然环境中三叶草的研究，分析其生长特点和扩散能力，得出其成为害草的可能性．从而为防止生态入侵的发生和保护当地生态平衡提供理论指导．

Grow Characteristics and Diffusion Capability of Trifolium in Natural Environment

Trifolium was introduced as exotic species in our country, mainly distributed in the south of Huaihe River and the southwest in china. It was cultivated as the lawn grass and fodder. In recent years, Trifolium was found in Jilin province. It grew vigorously and spread extensively. This is possible that Trifolium became a new kind of troublesome weed because of strong competitiveness and proliferation ability. Based on the research of Trifolium in the natural environment, we analyzed its growth characteristics and diffusion ability. The paper will concluded that the possibility of Trifolium as troublesome weed. ？ This research will supply theoretical guidance for prevention of ecological invasion and protection of local ecological balance.
