4种忍冬科植物浸提液对空气中微生物的抑制作用

Inhibitory Effect of Four Caprifoliaceae on Microbes in the Air

为了解园林绿化植物对微生物生长的作用,以金银木、天目琼花、接骨木和锦带花为材料,采用室外自然沉降法研究了该4种植物茎叶浸提液对空气中细菌、放线菌、真菌等三类微生物的影响。结果表明:4种植物不同浓度的浸提液对细菌、放线菌、真菌的生长均有影响,1 g.L-1的茎叶浸提液对细菌、放线菌、真菌菌落的生长具有促进作用或作用不明显;2 g.L-1的茎叶浸提液对细菌、真菌菌落的生长具有抑制作用,对放线菌菌落的生长具有促进作用;4 g.L-1的茎叶浸提液除锦带花和接骨木对放线菌菌落的生长分别具有促进作用和作用不明显之外,其余对细菌、放线菌、真菌菌落的生长均具有抑制作用,其中金银木和天目琼花茎叶浸提液对细菌的抑制作用最强,达到了99.7%。

In order to understand the effect of landscape trees on the growth of microbes, this study investigated the inhibitory effects of stem and leave extracts from Sambucus wiUiamsill Hance, Lonicera maackii Maxim, Viburnum SargentiU Koehne and Weigelas florida Bunge on bacteria, actinomycete and fungi by the method of outdoor natural setting process. The results showed that all the four plant extracts have effects on the growth of microbes from air. The concentration of 1 g · L^-1 extractions promoted or did not significantly promote the growth of microbes. The concentration of 2 g · L^-1 extractions inhibited the growth of bacteria and fungi, while promoted the growth of actinomycete. The concentration of 4 g· L^-1 extractions of the four plants inhibited the growth of bacteria, actinomycete and fungous, except that Sambucus williamsii and Weigelas florida promoted and had no effect on the growth of actinomycete, respectively.
