Thanh Hoa: Successfully preserved 3 rare orchid species


The Management Board of Xuan Lien Nature Reserve has bred 45,320 orchids of 3 species of Van Bac Hai orchid, Hai Long orchid and Thuy Tien Huong orchid.

The Management Board of Xuan Lien Nature Reserve, Thuong Xuan District, Thanh Hoa has successfully implemented the scientific project “Conservation, exploitation and development of genetic resources of Van Bac Hai, Hai Long and Thuy Tien orchids. Huong North Central region (period 2017-2022).

Thereby, 210 individuals of Van Bac Hai orchid, 1,175 individuals of Hai Long orchid, and 1,265 individuals of Thuy Tien Huong orchid were discovered in the North Central region.

vice president Xuan Lien Nature Reserve Do Ngoc Duong said that during the implementation of the project, the Management Board of Xuan Lien Nature Reserve investigated 42 routes with a length of 325.9km in 14 national parks and nature reserves in the North Central region. To determine the current status and distribution of these orchids, find solutions to preserve and propagate these precious orchids.

At the same time, 9 technical processes of propagation, planting and care of orchids were built and 3 commercial orchid growing models, 1 original seed garden model with 5,035 plants to provide seed materials for commercial plant production. Products.

Up to this point, the Management Board of Xuan Lien Nature Reserve has propagated 45,320 orchids of 3 species, including production methods by tissue culture method (30,000 plants/3 species), sprout separation method (15,000). trees/3 species).




In the coming time, the Management Board of Xuan Lien Nature Reserve will ask the People’s Committee of Thanh Hoa province and the Ministry of Science and Technology to create conditions for the unit to continue to register for the project “Improving the process and seed production Van Bac orchidHai Hai orchid and Thuy Tien Huong orchid for the North Central region” serving the conservation, exploitation and development of genetic resources of these species in a sustainable and effective manner, contributing to the conservation of natural biodiversity.

According to the research results of the Management Board of Xuan Lien Nature Reserve, the orchid species Dendrobium amabile O’Brien (Dendrobium amabile O’Brien) has a 35cm long stem, leaves are concentrated at the top of the stem, purple flowers. The tree often grows scattered in large, moisture-loving forests.

The tree regenerates by seed buds, growing from February to August of the solar calendar. Lan Thuy Tien Huong often grows under bushes in Pu Mat National Park, Xuan Lien Nature Reserve, Bac Huong Hoa Nature Reserve in Thanh Hoa, Quang Tri and Nghe An provinces.

Van Bac Orchid (Paphiopedilum callosum Pfitzer) or grows on soil, rocks, tree with narrow oval leaves, blooming time from April to June of the solar calendar. In the world, the tree is distributed in Thailand and Laos.

In Vietnam, the tree usually grows in dense primeval forests or on granite at an altitude of 300-1,300 meters. Van Bac orchid was discovered growing in Pu Luong Nature Reserve, Vu Quang National Park, Phong Dien Nature Reserve and other areas in Thanh Hoa, Thua Thien-Hue, Quang Tri, and Quang provinces. Binh, Ha Tinh.
Species Hairy Orchid (Paphiopedilum hirsutissimum Stein) has 5.2 cm long dorsal sepals, large flowers and blooms from March to May of the solar calendar. In the world, the tree is usually distributed in China and Thailand.




In Vietnam, the tree often grows in primeval forests or in heavily eroded limestone plateaus.

Hairy Orchid often grows in individuals and grows a lot in Pu Luong Nature Reserve, Xuan Lien and other areas in the provinces of Quang Binh, Quang Tri, Thua Thien-Hue.

These orchids have high economic value, so many people in the provinces have exploited them to sell, plus deforestation has taken place, which has made these orchids less and less in danger of disappearing. gene source.

Currently, these 3 species of orchids only grow very little on limestone cliffs, caves, and mountain slopes in protected areas and national parks of the North Central provinces, so the successful implementation of the above scientific project has helped. These three orchid species are preserved and avoided the risk of species extinction./
