在植物学和本草学发展史上,人类意识到永久保存标本的重要性并做出认真的努力制作标本,建立标本室(馆)是近三、四百年的事,普通蜡叶标本的制作,都是把采来的标本压在吸水材料(常用草纸)中间,反复换纸,直至干燥为止,这种经典的方法所需时间长,换纸、干燥纸的工作量大,肉质多计标本更加费工费时。天南星科某些植物的块茎压放一年以上仍在发芽生长,不能变干。更重要的是象马齿苋科、景天科植物在 In the history of the development of botany and herbal medicine, humans realized the importance of permanent preservation of specimens and made serious efforts to make specimens. The establishment of a specimen room (a museum) was nearly three or four hundred years old. The production of common wax leaf specimens was It is the pressure of the collected specimens in the middle of the water-absorbing material (commonly used grass paper), and repeated paper change until it is dry. This classic method takes a long time, and the workload of changing paper and drying paper is large, and the meat quality is more expensive. Labor hours. The tubers of certain plants of Araceae are still germinating and growing for more than a year and cannot be dried. More importantly, like the purslane and sedum plants
