Embodiment 1

[0013] Color fixing step: add copper acetate to 50% acetic acid solution to obtain a saturated solution, then mix the saturated solution with acetic acid in a ratio of 1:4 to obtain an aqueous solution of copper acetate, heat the leaves of green plants in the aqueous solution of copper acetate until the plant After the specimen turns yellow-green first and then green, wash the plant leaves with clean water;

[0014] The product obtained in the plasticizing step and the color fixing step is put into methyl methacrylate solution, soaked for 1-10 hours, and irradiated with sunlight for 5-24 hours.

Embodiment 2

[0016] In the color fixing step, the red plant leaves are heated in the acetic acid carmine solution until the plant leaves turn yellow and then red, and then the plant leaves are washed with clean water.

[0017] The product obtained in the plasticizing step and the color fixing step is put into methyl methacrylate solution, soaked for 1-10 hours, and irradiated with sunlight for 5-24 hours.

Embodiment 3

[0019] In the color fixing step, the plant leaves are heated in 50% acetic acid solution until the plant leaves turn yellow, and the plant leaves are rinsed with clear water;

[0020] The product obtained in the plasticizing step and the color fixing step is put into methyl methacrylate solution, soaked for 1-10 hours, and irradiated with sunlight for 5-24 hours.

Abstract

The invention discloses a herbarium fixing and plasticizing method, which comprises the following procedures: color fixing procedure: A. heating the green plant leaves in copper acetate aqueous solution until the herbarium changing into chartreuse and green again, and using clean water to flush the leaves of plant; or B. heating the leaves of red plant leaves in acetic acid magenta until the plant leaves become yellow and red again, using clean water to flush the plant leaves; or C. heating the plant leaves in 50 percent acetum until the plant leaves become yellow, and using clean water to flush the plant leaves; plasticizing procedure, putting the product in the color fixing procedure into methacrylic acid methyl ester solution for immersing for 1 to 10 hours and shining by sunlight for 5 to 24 hours. The plant leaves specimens manufactured by the plant leaves specimens color fixing and plasticizing method are not easy to fade, break or be damaged by worm, and is not easy to milden and rot.

Description

technical field [0001] The invention relates to a method for making a plant leaf specimen, in particular to a method for color-fixing and plasticizing a plant leaf specimen. Background technique [0002] At present, plant wax leaf specimens are often used in biological experiments in order to more directly understand the shape and structure of plant leaves. But with regard to present preparation method, there is certain defect, mainly is that plant leaf sample is easy to fade, broken and easily eaten by insects, mildew, is unfavorable for long-term preservation. Contents of the invention [0003] The present invention aims at overcoming the disadvantages that the herbarium plant leaf specimens made in the prior art are easy to fade, broken and easy to be eaten by moths and mildew, which is not conducive to long-term preservation, and provides a kind of herbarium which is not easy to fade, break and be eaten by moths and mildew. Color fixation and plasticization methods fo...
