What should be paid attention to in the collection and production of plant wax leaf specimens?

When making specimens, attention should be paid to:

1. Make the branches, leaves, flowers and fruits as flat as possible, with some leaves facing upwards, and observe the characteristics of the leaves.

2. It's not easy to do. Open a hot water tank first, then cut or cut, drip dry water and then press.

3. The specimens in the first stage and the last stage are wrongly placed, so as to keep the balance of the pile of specimens and prevent them from toppling under the condition of uniform stress.

4. When changing paper, the key step is related to the specimen quality.

When changing paper, pick it up one by one, put it in a small paper bag, and then write the collected numbers together.

Precautions:

1. Besides osmanthus leaves, leaves of coral, maple, mulberry, linden, poplar and hazel can also be used to make veins bookmarks.

2. When heating, the beaker must be placed on the asbestos net. If heated directly, the beaker will break due to uneven heating.

Used liquid can be stored in an empty container so that it can be used again next time. General liquid can be recycled for 4 ~ 5 times.

4. If there are too many treated leaves, you can change the beaker and add 10% to water and sodium hydroxide.
