Tara - a good tree species for returning farmland to forests
The country's policy of returning farmland to forests has won the sincere support of the vast number of mountain farmers. But what kind of tree is the land that has been retired? This has become a new problem. In an interview with Baise in Guangxi recently, the author was informed that a new special economic tree, Tara Tree, introduced from the new Kotala planting and development demonstration site in the city has potential economic, social and environmental benefits and many advantages. It may be one of the first tree species that the mountain peasants' brothers implement the project of returning farmland to forests as soon as possible. Tara, also known as “thorn cloudâ€, is a perennial plant that originates from Peru and other countries in northwestern South America. Currently, only Baise City in Yunnan Province and Guangxi Zhuang Autonomous Region is introduced and cultivated. The product market is in short supply. According to reports, the tree grows to a height of more than 3 meters, with resistance to dry heat, rapid growth, evergreen characteristics, flourishing throughout the year, flowers blossoming, beans caught. The growth period of the whole tree is as long as 50 years, and the actual harvest period of the tree is about 20 years. The year after the transplant, the harvest II increases year by year. Its real fruit, Tara bean, can be processed into more than 100 types of chemical, textile, food, and pharmaceutical raw materials such as Tara, Tara, and Tara Tannin, which have important and extensive uses in industry. In particular, its seeds can be used to extract stigmasterol and sitosterol (the former is the main raw material for the production of "cloud 120", which can produce hypolipidemic drugs, worth more than 1,000 US dollars / kg, domestic imports), is a rare low-fat , high-protein, non-toxic edible woody legumes.In addition, the leaves can also feed the livestock, is a good feed for the cultivation of lean meat livestock.Bean husk can be processed into tara powder by smashing, the current market price is 1,500 yuan RMB 2,000/ton, seed kernel RMB 3,000/ton, and the trees can be harvested continuously for more than 20 years with a little economic value, and the economic value is considerable. The improvement in soil and water conservation and ecological environment is even more rewarding. It can be regarded as greening the mountain and regulating the climate. With its unique and unique climate and soil conditions, Baise City, Guangxi Province, has devoted several years of efforts to its original eight seeds and has now expanded into a demonstration base of 200 acres of Tara Seedlings. This will create favorable conditions for the large-scale development in the future.
