在制作绿色植物标本时,大家都曾遇到这样的问题:如何使压制的标本不变色呢?经过我们这一期来的研究,初步摸索到了一点经验。方法是这样的:首先用硫酸铜0.5%,苦味酸0.5%,福■马林4%,蒸馏水或清水95%,配制成固定液,将所采得的标本用开水荡一下(六约2—3秒钟),再放入上述的固定液中浸■,约浸一尽夜待其转变为淡绿色时即取出晾干,然后进行压制。在压制过程中勤晒勤换纸(如无太阳可用火烘)。经过这样处理所制成的标本,干后成深绿色,制成的整套标本很美丽。这个方法很简单,也容易做。现在介绍出来,供大家参考,希望大家多提意见,以便今后作进一步的讲究。
When making green plant specimens, we all encountered such a question: How to make the pressed specimens not discolour? After a period of our research, we initially found some experience. The method is as follows: First, use 0.5% copper sulfate, 0.5% picric acid, 4% bovine serum, 95% distilled water or clean water to prepare a fixed solution, 3 seconds), and then placed in the above-mentioned fixed liquid immersion ■, about immersed overnight to be light green when it is removed to dry, and then pressed. In the process of reprinting Qinxian Qin paper (if there is no sun available fire bake). After this treatment made of specimens, dried into a dark green, made of the entire set of specimens is very beautiful. This method is simple and easy to do. Now I will introduce it for your reference. I hope Members will make more comments so that they will pay more attention to the future.
