湖泊是人类重要的饮用水源。有害藻华的存在会对湖泊水质造成严重威胁。本研究探讨了使用桉树植物和叶子提取物控制水生环境中藻类增殖的可行性。处理30天后，种植桉树和桉叶提取物的处理的抑制效率分别为85.8%和20.9%。化感作用和大量营养素竞争性吸收的协同效应归因于中生态系统中藻类增殖的有效控制。此外，微生物群落结构分析表明，桉树植物或叶子提取物对物种多样性及其相对丰度没有不利影响。使用桉树来控制藻华的选择将取决于地理区域内的环境和经济考虑。 (C) 2019 Elsevier B.V. 保留所有权利。
Lakes represent an important source of drinking water resource for human beings. The presence of harmful algae blooms can pose a serious threat to lakes water quality. This study explored the feasibility of using eucalyptus plants and leaves extracts for controlling algae proliferation in an aquatic milieu. After 30 days of treatment, the inhibitory efficiencies were 85.8% and 20.9% for treatments planting eucalyptus and eucalyptus leaves extracts, respectively. The synergistic effects of allelopathy and competitive absorption for macro nutrients were attributed to the effective control of algae proliferation in the mesocosm systems. Moreover, the analysis of microbial community structures indicated that eucalyptus plants or leaves extracts had no adverse effect on species diversity and their relative abundance. The choice of using eucalyptus to control algae bloom will be dictated by environmental and economic considerations within a geographical region. (C) 2019 Elsevier B.V. All rights reserved.
