许多土生地衣如羊角衣、石蕊等,按常规方法处理的标本,往往裂散,即使不裂散的标本,装袋后稍一挤压就会破碎。为解决这一问题,借签了国外植物标本室保存和制作土生地衣的方法,结合自己的经验,摸索出乳胶固着的方法。 Many native lichens, such as gossypium, litmus, etc., specimens processed by conventional methods tend to break up, even if the specimen is not cracked, bagging slightly crushed after crushing. In order to solve this problem, the method of preserving and producing native lichen in foreign herbaria was explored, and combined with our own experiences, the method of fixing latex was explored.
