9种常见灌木滞尘和抑菌的初步研究

研究闽南师范大学校园中9种常见绿化灌木植物的滞尘和抑菌效应。结果表明，不同灌木植物之间有着明显的滞尘能力差异。最大的单位体积滞尘量约为最小的11倍。马缨丹的单位体积滞尘量最大，灰莉的单位体积滞尘量最小。9种灌木植物对大肠杆菌、枯草芽孢杆菌和金黄色葡萄球菌的抑菌作用差异很大。9种灌木植物对大肠杆菌有着明显的抑制作用，抑菌率均达到45%以上；对枯草芽孢杆菌的抑制作用差异很大，抑菌率在14.1%~96.5%之间；海桐和鹅掌柴对金黄色葡萄球菌无抑菌作用。

A Primary Study on Dust Retention and Bacteriostasis Effect of Nine Common Shrubs

Dust retention capacities and antimicrobial activities of 9 common shrubs occurring in the campus of Minan Normal University were examined. The results implied that the dust retention capacities of the shrubs were significantly different. Lantana demonstrated the biggest amount of the dust retention, 11 times higher than the smallest one, African jasmine. Significant differences were also observed in antimicrobial activities among 9 shrub species to Escherichia coil, Bacillus subtilis and Staphylococcus aureus. All the 9 shrubs demonstrated strong inhibition capacity to E. coil, with the inhibition rate of above 45%. The inhibition rates of 9 shrubs to B. subtilis were between 14.1% and 96.5%.Pittosporum tobira and Schefflera octophylla had no inhibition effect toward S. aureus.
