白千层树皮


千层树是生长在澳洲的一个植物属，目前已知有236种，其中230种原产于澳洲，其余生长在印度尼西亚、新几内亚、新喀里多尼亚和马来西亚，为桃金娘科植物。白千層屬，又名千層樹屬。


千层树和红千层（Callistemon）亲缘关系较近，两者主要区别是千层树的雄蕊成束，红千层的雄蕊是分别独立的。


野生的千层树主要生长在靠近水边或沼泽地边缘。


千层树的种类很多，不容易区分，一般为了和红千层区分，都叫做“白千层”。也有小型的被成为“蜜桃金娘”，也有可以提炼香精油的种类，由于提炼出的油叫做“茶油”而被称为“油茶树”（Melaleuca alternifolia），有的灌木树叶当年被早年移居的欧洲人作为茶的代用品。千层树的树皮色泽较淡，但生长在水边的树有时被树叶的颜色侵透显成棕色。


澳洲本土的一些昆虫以千层树的叶为食。


白千层（Melaleuca quinquenervia）被引进美国亚热带地区，想以它们改造沼泽，结果成为一种入侵有害物种。在一些地方則做為行道樹。


千层树提炼的油可以应用到食品和医药工业中，因其具有抑制細菌的功用。

形态

Run scheduled task as local user group (not BUILTIN)

Image
0 I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem? Are there some restrictions to the Created User Group compared to BUILTINUsers? scheduled-tasks taskscheduler windowstaskschedule share | improve this question asked Nov 15 '18 at 15:36 Far...
