Myanmar teak, commonly known as Carmine, Blood Tree, Castanea mollissima and Thai pomelo, belongs to Labiatae of Dicotyledon, Labiatae, Labiatae, Labiatae. Teak is a tropical tree species, which requires higher temperature. Vertical distribution is mostly found in low hills and plains below 700-800 meters above sea level. Teak does not warp and crack when the sun, rain, drying and wetting change is large; it has strong water resistance and fire resistance; it can resist termites and sea bugs in different sea areas, and is extremely resistant to decay. Drying performance is good, adhesive, paint, wax performance is good, wood hardness is relatively small, cutting is not difficult, but because of containing silicone oil easy blunt knife. Because of its excellent nail holding ability and good comprehensive performance, it is recognized as a precious tree species in the world.
Teak is abundant in tropical areas of Southeast Asia, with Thailand and Myanmar as **. Because teak is precious and small in quantity, Thailand regards teak as national treasure and prohibits export in 2005. In 2010, the Myanmar government also issued relevant cutting restrictions to reduce the cutting and export of teak. In the same year, the International Wood Collection expanded the categories of teak trees and divided them into Verbenaceae and Magnoliaceae. The prices of materials of different families and genera are quite different, and the raw materials of Verbenaceae are between 18,000 yuan and 18,000 yuan. The price of Magnoliaceae raw materials varies from 9000 yuan to 15000 yuan per party.
Myanmar teak, also known as carmine, purple teak, blood tree, aliphatic tree, purple oil tree (Yunnan), buried mulberry (Dai translation), hardwood tree (Dai translation), stone salt, ring hole tree, is a large deciduous or semi-deciduous tree, the tree is about 30 meters high, ** breast diameter 1.6 meters, straight trunk.
Myanmar teak is the main afforestation tree species in Myanmar, is also an important export resource of Myanmar, has the reputation of "ten thousand trees **". After the 1980s, with the traditional teak exporter Thailand and Indonesia ceasing the export of primitive forest teak, Myanmar became an exporter of teak. Within a few years, Myanmar's original forest teak resources decreased sharply, and the country began to study the artificial cultivation techniques of teak. The vast majority of teak exported from Myanmar is the artificial teak planted since the 1980s. Teak is a tropical tree species, which requires higher temperature. Vertical distribution is mostly found in low hills and plains below 700-800 meters above sea level. Teak is a photophilic tree species. The annual average temperature of origin is 20 -27,** low temperature is 2, annual rainfall is 1100-3800 mm. The dry and wet season is obvious. The strong positive tree species can grow on red soil and lateritic red soil developed from sandy shale and granite. They like deep, wet, fertile and well drained soil.
Teak can be planted in places where there is no low temperature frost (- 1 ~2 C), shallow roots, large crowns, vulnerable to wind damage and shelter from wind. Suitable growth temperature: 43 - 48 ** temperature and 2 ** temperature.
Teak grows fast and has strong germination ability. It can regenerate after cutting. Under the condition of artificial management, water and fertilizer are abundant and grow fast. Generally, the diameter can reach 10-15 centimeters in about 10 years, 20-30 centimeters in about 20 years, and the breast diameter of wild teak can reach about 50 years.
Myanmar teak is a popular material for making high-grade furniture, flooring, indoor and outdoor decoration. It is suitable for shipbuilding, open-air buildings, bridges and so on, especially for the manufacture of ship decks. It has strong corrosion resistance to many chemical substances, so it is suitable for wood products used in chemical industry. Especially used in the floor, corrosion-resistant, wear-resistant, bright as new, beautiful patterns, elegant tone, good stability, small deformation, is really the floor of the **. Because teak is rare, with large leaves, excellent materials and great value, it has been used as street trees, residential greening, garden decoration and greening around in Guangdong and Fujian provinces at this stage. It has even become a hedge commodity. Atlas Reference [1]
Myanmar teak is medium in weight, not easy to deform, waterproof and corrosion-resistant. Teak is used to make the most luxurious yachts in European countries. The deck of TITANIC (Titanic) is paved with teak. It still looks good today. Centuries-old cathedrals and ancient buildings are also made of teak flooring. Teak is precious. It lasts at least 50 years from growing to maturing. In the natural environment, there are only 1 to 5 trees per mu. It also contains very heavy oil, which keeps it unchanged and has a special fragrance that repels snakes, insects, mice and ants. What's more amazing is that its polished surface color is golden yellow through photosynthesis oxidation, and the color will be more beautiful over time.
