Method of making plant specimens

The method of making plant specimens is as follows:

Raw materials/tools: flowers, photo frames, glue, paper.

Step 1: Treat flowers and plants.

Self-made flower specimens need to be processed first, so as to be better preserved. To collect fresh flowers and plants, we should trim them first, cut off dead branches, rotten leaves and residual flowers, try our best to ensure the integrity of the flowers and plants and make the finished products beautiful, and then clean them.

Step two, pressing the sample.

Pressing the specimen is to make the specimen dry and smooth faster. Put the specimen on undyed absorbent paper or newspaper, and pay attention to the fact that the paper needs multiple layers to overlap, so that the specimen can be more flat. Then spread multiple layers of paper on the specimen, clamp the specimen holder, press the heavy object, change the paper frequently a few days ago, and then remove the specimen for binding after it becomes brittle.

Step 3: bind.

Bind the specimen on A4 paper or other paper books, carefully stick it with glue or tape, or over-plastic the photos, which can be better waterproof and fracture-proof, and effectively prolong the preservation time.

Step 4, store.

The bound specimens should be placed reasonably to prevent mildew and moth-eaten, which will affect appreciation. It should be stored in a cool and ventilated place to avoid direct sunlight, which will lead to the fading of the specimen. There is also a need to check regularly to see if there are any moth-eaten or moldy phenomena. If it is found, it is necessary to deal with it in time, which is conducive to the long-term preservation of the specimen.

Significance of plant specimens

Plant specimens are of great significance to plant classification. Botanists can examine plants collected from different areas through specimens. Some large herbarium often collect more than one million plant specimens, which botanists use to describe and identify plants. As a new technology in the second half of16th century, plant specimens greatly promoted the rapid development of plant classification at that time.
