Description

Technical Field

[0001] The invention relates to the technical field of plant specimen preparation, and in particular to a method for preparing an artistic specimen of a Qinling stone butterfly. Background Art

[0002] Petrocosmea qinlingensis WT Wang is a perennial herbaceous plant belonging to the Gesneriaceae family, Petrocosmea genus, and Chinese Petrocosmea group. Its type specimen was collected by Mr. Fu Kunjun in Chadian, Mian County, Shaanxi Province in 1952, and the specimen is now treasured in the herbarium of the Institute of Botany, Chinese Academy of Sciences. According to records, the specimen was collected on a rock at an altitude of 650 m. Its flowers are light pink and purple, and it was identified as Chinese Petrocosmea sinensis at that time. In 1981, when the famous plant taxonomist Wang Wencai observed the specimen, he found that the inner surface of its corolla upper lip was covered with white soft hairs, which was obviously different from the hairless inner surface of the corolla of Chinese Petrocosmea. Therefore, it was identified as a new species and named Qinling Petrocosmea. In the more than 30 years since its naming, many field surveys have been carried out, but its wild population has not been found. It was not until 2013 that it was rediscovered in the second wild plant resource survey in Shaanxi Province and the extremely small population wild plant resource survey in Hanzhong City. At present, this plant is a national second-level rare and endangered protected plant unique to the Qinling Mountains. The wild population has an extremely narrow geographical distribution and a small number of individuals. It has been listed as critically endangered in the China Rare and Endangered Plant Information System. Qinling Stone Butterfly is the northernmost plant of the Stone Butterfly genus, which is of great value for studying the population evolution of this genus.

[0003] Gesneriaceae plants are highly ornamental because of their beautiful and bright flower colors and shapes. In the United States, there is a special Gesneriaceae Cultivation and Ornamental Association, and the association's journal is GLOXINIAN (an American Gesneriaceae plant). Qinling Stone Butterfly has a high ornamental value for its gorgeous purple corolla and elegant and pleasant emerald green leaves. Qinling Stone Butterfly has basal leaves, rosette-shaped plants, 2 to 6 inflorescences, and lavender corollas. It is suitable as a new indoor potted flower. It is a wild flower resource with high development value and important ornamental value. Cultivating in a nursery not only increases the plant species diversity of the nursery, improves the ecological and ornamental benefits, but also has important significance for its ex situ conservation, as well as in popularizing botanical knowledge and raising people's environmental awareness. After tackling the artificial breeding technology of Qinling Stone Butterfly, the Qinling Stone Butterfly Research and Protection Team has established a stable indoor artificial rapid asexual and sexual reproduction technology system, and then large-scale breeding and outdoor domestication, and finally obtained a certain scale of Qinling Stone Butterfly seedling population. On this basis, the Qinling Stone Butterfly Research and Protection Team used artificially bred Qinling Stone Butterflies to develop various eco-bottles and ecologically simulated cultivation bonsai with the Qinling Stone Butterfly as the theme.

[0004] The Qinling Stone Butterfly has a relatively short flowering period, and after the flowers fall off, it will affect the ornamental value of the Qinling Stone Butterfly. Therefore, it is particularly important to use a certain process to dry and fix the Qinling Stone Butterfly to make various cultural and creative products that can be preserved and displayed for a long time. As a cultural carrier, cultural and creative products not only bring people artistic beauty, but are also an important carrier for scientific and popular science propaganda. Based on this concept, the Qinling Stone Butterfly art specimen developed in this study is not only beautiful, but also easy to preserve and not easy to damage. This Qinling Stone Butterfly art specimen is easy to carry and can be used as a souvenir for scientific and popular science propaganda. It is of great significance to promote the ecological protection of the Qinling Stone Butterfly.

[0005] The leaves of Qinling Stone Butterfly are grassy, ​​thin and juicy. The leaves of specimens made using the current traditional method of making wax leaf specimens are easy to fade and turn yellow, and are not easy to preserve and carry. Summary of the invention
