一种腊叶标本快速干燥方法的研究

Study on a Drying Method of Herbarium Specimen

为解决传统腊叶标本在自然干燥过程中存在的干燥耗时过长,标本易变色、发霉及花、果、叶容易脱落等问题,以及提高腊叶标本的质量与制作效率,笔者选择加热板干燥法、热风机干燥法与传统的自然干燥法,对植物干燥效果进行比较。结果显示,热风机干燥法对植物花和果的保色效果明显优于其他两种干燥方法,且耗时最短,植物的整体外观良好,但热风机干燥在控制温度和工作时长方面还有待进一步研究。

Objective In order to solve the problem that the drying of the traditional herbarium specimen in the natural drying process takes too long,the specimens are easy to lose color,mold,and the flowers,fruits and leaves are easy to fall off,improve the quality and production efficiency of the herbarium specimen,thereby providing a reference of improving the technology of herbarium specimen production. Method:By searching the literature,the author chooses the heating plate drying method,the hot air fan drying method and the traditional natural drying method,and compares the actual plant drying effects to obtain the best drying method. Results:The drying method of the hot air blower was superior to the other two drying methods in flower and fruit color retention,and the time was the shortest,and the overall appearance of the plant was good. Discussion:Hot air drying still requires further research in terms of temperature and duration of control. The hot air blower and the heating plate are convenient to carry and have high utilization,which is more conducive to the preparation of theherbarium specimens in the future.
