The dachshund tree is very interesting just by hearing its name, and after a closer look, I realized that it is indeed not simple. Originally, the dachshund tree is the national flower of Thailand, locally known as "Dok Khuen", and its yellow petals symbolize the Thai royal family. The "World Horticultural Expo" held in 2006 at the Royal Agricultural Research Center is named after the dachshund tree as "Royal Flora Ratchaphruek 2549", "Ratchaphruek" is another name for "Dok Khuen" and "2549 AH" That is, in 2006, the "Chongsong" is King Bhumibol, which is one of the celebrations of the 60th anniversary of the accession of the King of Thailand. The dachshund tree is also the "provincial flower" of the southern Indian state of Kerala, locally known as "Kanikkonna", and is used for local New Year (Vishu) ceremonies. In addition to these extraordinary identities, the dachshund tree itself is also full of treasures and has a wide range of uses.
1. Plant introduction
The dachshund tree (scientific name: Cassia fistula L.), also known as Abol, horn tree, Persian acacia pod, is a plant in the legume family Cassiaceae. deciduous trees, up to 15 meters tall; Branches slender; The bark is grey, rough when old, dark brown. leaves 30–40 cm long, leaflets opposite, thinly leathery, broadly ovate, ovate or oblong, margined full, slightly pubescent on both sides when young, glabrous when old; The veins are slender and pronounced on both sides. Inflorescences up to 30 cm or more, dispersed, drooping; The flowers open at the same time as the leaves, about 4 cm in diameter; The petals are yellow, inverted ovate, nearly equal in size, with distinct veins. Pods cylindrical, 30–60 cm long, blackish-brown, not cracked, grooved; 40-100 seeds, separated by the diaphragm. Flowering period from June to August; The fruit period is October.
2. Habitat
It is native to India, Myanmar and Sri Lanka. It is cultivated in all provinces and regions of southern and southwestern China. Temperature-loving tree species, frost-damaged areas can not grow, the suitable temperature for growth is 23-32 °C, the minimum temperature can withstand -3 °C, usually grows well in South China; Sex loves light and can also withstand a certain shade; Can tolerate drought, can also tolerate water and moisture, but avoid standing water; It has strong adaptability to soil, prefers to grow in moist, fertile and well-drained neutral alluvial soil, with sandy loam as the best, and can also grow on dry and infertile soil.
3. Application value
The dachshund tree blooms in early summer, full of golden yellow, the inflorescence sways with the wind, and the petals fall like rain with the wind, so it is also known as "golden rain". The slender autumn fruit pods droop like sausages, which are rare ornamental trees and are widely used in landscaping. A common garden ornamental tree in southern China, the bark contains tannins, which can be used as a red dye. Roots, bark, fruit bowls and seeds can be used in medicine, and are used in Tibetan medicine, Uighur medicine, Dai medicine, etc., and can treat food poisoning, bloating, hepatitis, liver disease, constipation and other diseases. The wood is heavy, strong in decay resistance and beautiful in luster, and can be used as timber such as pillars, bridges, vehicles and agricultural tools.
Due to its extremely high ornamental value and medicinal value, the cultivation area of dachshund tree in my introduction is not growing, and the demand for high-quality seedlings is also increasing, and the commonly used seed propagation not only has a long reproductive cycle, high manual management costs, but also is prone to hybrid mutation, resulting in a decline in seed quality. If the plant non-test tube rapid propagation technology invented by researcher Li Changxiao is adopted, it can solve these problems well. Plant non-test-tube efficient rapid propagation technology (TERNPC), which is essentially asexual reproduction - (by cutting a high-quality mother plant leaf and bud can be cultivated into a complete plant), compared with traditional seed propagation, this technology greatly shortens the reproductive cycle, and can ensure the high-quality genes of the original plant to the greatest extent, no mutation. It has the characteristics of low cost, short cycle, high reproductive coefficient, small influence by seasonal factors, low cost of large-scale production, high survival rate and simple management. If the research and development is successful, a large number of high-quality, cheap sausage seedlings will be produced in a short period of time, which can quickly seize the existing seedling market and obtain huge economic benefits, and at the same time, it can also expand overseas markets and provide seedlings for Southeast Asian countries such as Thailand, and the future market prospects are broad, which is a good project.
