摘要
通过对校内１２个树种采用不同方法的测试结果表明，所测试树木均有一定的杀菌作用，其中七叶树、云杉、圆柏较强，其杀菌效果一天内变化相对平缓，所有树种一天中杀菌作用最强的高峰期在１６：００时前后。成熟叶的杀菌能力大于幼叶。经比较，室内水插枝法在排除外界影响方面优于自然沉降法，是测试树木杀菌作用简易可行的方法。
The twelve species of ornamental trees investigated all possessed disinfection and theeffeet of Chinese buckeye, spruce, Chinese juniper were better and changed less in a day thanothers. The disinfectant effects of all species showed strongest at about 16: 00 oclock in a day,and the functional leaves behaved stronger than the younger leaves. The method of 'indoor dipping in water' proved to be a simple practical method and was better than the method of' outdoor sedimentation'.
