A method for efficiently and quickly preparing wax leaf specimens of plants

Abstract

The invention provides a method for efficiently and rapidly making wax leaf specimens of plants, which comprises the following steps: firstly, pruning and shaping the collected plant specimens, removing overlapping and defective branches, leaves, roots, tubers and flowers, and then applying absorbent paper, Corrugated paper, bagged color-changing silica gel and trimmed plant specimens are placed on a specimen holder in order, and the number of plant specimens reaches 3‑5, then another specimen holder is covered, and the two specimen holders are tied tightly with a binding rope. Put the bound specimen clips into a drying box with a temperature of 110°C for drying, take them out and place them in a dry room after drying, and take out the plant wax leaf specimens when the temperature returns to room temperature. The present invention adopts bagged color-changing silica gel particles with good hygroscopic effect and air-permeable corrugated paper to greatly shorten the time for pressing plant wax leaf specimens, and the prepared plant wax leaf specimens have no discoloration and damage problems. The operation of the present invention is simple, fast, and extremely Greatly improved the work efficiency and the quality of plant wax leaf specimens.

Description

technical field [0001] The invention belongs to the technical field of agricultural scientific research and plant identification, and in particular relates to a method for efficiently and rapidly preparing wax leaf specimens of plants. Background technique [0002] The traditional preparation method of wax leaf specimens is the absorbent paper pressing method. First put the absorbent paper on the specimen folder, place the plant specimens on the absorbent paper, then cover the absorbent paper and place the plant specimens, so that the stack is about 15cm high, and the other cover is covered. A specimen holder; this method uses repeated changes of absorbent paper to absorb moisture from the plant specimen and allow it to dry. [0003] Existing color retention technology: soaking in copper ion solutions such as copper acetate solution to replace magnesium ions in chlorophyll, so that the green part of the plant specimen remains green. This method is referred to as the copper i...

AI Technical Summary

Problems solved by technology

[0005] One is time-consuming

It usually takes 5-10 days to complete the process of pressing and shaping the wax leaves of plants by using the traditional absorbent paper pressing method, which takes a long time, and repeated replacement of the absorbent paper during the pressing process will easily cause the specimen to break (damage); replace Factors such as untimely absorbent paper, continuous rain in the weather, indoor humidity, and insufficient hands for making specimens may easily lead to problems such as rot and discoloration of plant specimens, resulting in low efficiency, waste of plant resources, high labor costs, damage to plant specimens, and many processes. Complicated operation, etc.

[0006] The second is that the color of wax leaf specimens of plants is quite different from that of living plants, resulting in a low identification rate of specimens

Pressed by traditional methods, some plants have serious discoloration due to their own characteristics or high water content in stems and leaves, especially yellowing, browning, blackening, etc.

In addition, if the method of copper ion replacement is used to preserve the color, taking the green leaves of plants as an example, there are many kinds of green - green, grass green, yellow green, green, dark green, etc. The method of copper ion replacement cannot accurately display the original color of the plant. Green, which distorts the color of herbaria

[0007] Three is high cost

First of all, the labor cost is high, it takes a long time, and the workload of replacing the absorbent paper is heavy

Problems such as discoloration and decay cause waste of plant resources. If waste is caused to precious and rare plants, the loss is immeasurable
