校园绿地植物群落配置模式的抑菌功能

Antibacterial Function about Arrangement of Plants in Campus

以吉林农业科技学院不同配置的植物群落为样地,测定分析其抑菌功能。结果表明,植物群落具有一定的抑菌作用。夏季单一树种群落配置中以红皮云杉林的抑菌效果最好,抑菌率为21.7%;复层群落配置中红皮云杉+水曲柳+连翘+榆叶梅的抑菌效果最好,抑菌率为33.2%;相同的植物群落在夏季的抑菌效果比冬季的要好。

An experiment was conducted to study the antibacterial function of plant communities under different collocation patterns by using the plant communities in Jilin college of agricultural science and technology as materials. Results showed that the plant communities had a certain degree of antibacterial action. In summer,the community composed of single plant species of Picea koraiensis Nakai had the best antibacterial function with restraining rate of bacteria of 21.7%. For the multi-level plant community, the most obvious antibacterial functions were exhibited by Picea koraiensis Nakai,Fraxinus mandshuri-ca Rupr., Forsythia mandshurica Uyeki and Prunus triloba Lindl. with the restraining rate of bacteria of 33.2%. The antibac-terial function of the same plant community in summer was better than that in winter.
