It is famous for its "big skin and thin skin, more juice and less residue, and crispy meat"

Name. Tongling ginger is rich in nutrition. According to the test, it contains protein 1.4%, sugar 8% and fat 0.7%. In addition, there are calcium, phosphorus, iron, carotene, thiamine, riboflavin, nicotinic acid, antithrombotic, inorganic salts and other essential nutrients. Ginger has the functions of invigorating stomach, stopping bleeding, promoting qi circulation, dispelling cold, resolving phlegm and detoxicating, sweating and clearing heat, seasoning vegetables and stimulating appetite. Tongling people like to eat ginger and regard it as a good medicine. Tongling has a folk song: "A piece of ginger is better than a prescription" and "A cup of ginger soup is suitable for all ages". Sugar ginger, vinegar ginger and dried ginger processed from Tongling ginger have always been very popular. Especially rock sugar ginger is one of Tongling's foreign trade products. Tongling ginger is one of the "eight treasures" in Tongling, a perennial herb and an annual cultivated crop. Tongling ginger was scientifically identified by the Horticulture Institute of Anhui Academy of Agricultural Sciences, which belongs to the type of white ginger and row ginger. Fresh ginger skin is slightly yellow, ginger pieces are Buddha-shaped, and petals are thick and dense. Ginger is full, white, tender and juicy, spicy and not choking, and it is a multifunctional edible product. Tongling ginger is famous for its "big skin and thin skin, more juice and less residue, and crispy meat". Tongling has a long history of producing ginger, which was planted as early as the Spring and Autumn Period. During the Northern Song Dynasty, Tongling became a famous ginger producing area in China and was listed as a tribute of the imperial court. According to Jiajing's Tongling County Records, Tongling ginger has become a "hot" specialty in the Ming Dynasty. "The city produces ginger, garlic, ramie, peony bark and the like, and there are vendors nearby, but most of them are vendors in distant cities." (clear. Zhao Jinfeng). Qing Shunzhi 13 (1656) recorded in Tongling County Records and Products that the output of ginger at that time was "not less than100000 tons per year". During the Republic of China, the annual output was about 720 tons. There are six private companies dealing in ginger in Datong, which buy fresh ginger every year and sell it to Anqing, Wuhu, Zhenjiang and Yangzhou. Famous sauce gardens such as Hu Yumei in Anqing, Simei in Yangzhou and Hengshun in Zhenjiang bought Tongling ginger to process sugar iced ginger, sweet and sour ginger and sauce ginger. In the early days of the People's Republic of China, ginger was still managed by private businessmen. In the late 1950s and early 1960s, due to one-sided grain production, the planting area of ginger was affected and the yield was also reduced. In the 1980s, under the guidance of actively developing diversified business policies, the area and output increased continuously. Except for some ginger purchased by supply and marketing cooperatives, most of them are directly purchased by the director of the sauce factory or transported to the market for self-sale. From 1964 to 1990, 1966 was the largest purchasing volume of the supply and marketing department, with a total purchase of 60,800 kilograms, and 1978 was the smallest, with only 350 kilograms. In 1970s, the annual planting area hovered around 200 mu, and the annual output of ginger was generally around 150 tons. After the Third Plenary Session of the Eleventh Central Committee, ginger planting developed rapidly. In 1980, 3 15 mu of ginger was planted, with a total output of 324.3 tons. 1985 planted 945 mu of ginger, with a total output of 1 122.6 tons; 1990 planting ginger 1362 mu, yield113 kg, total output 15 16 tons. With the development of ginger industrialization, the enthusiasm of ginger farmers is unprecedented. In 2005, the planting area of ginger has reached 8000 mu, and the total output has reached 1 10,000 tons. A number of leading enterprises have emerged, with more than 40 varieties of products in five categories. Tongguanle brand appetizing ginger selenium-enriched Tongling white ginger, Heping brand sweet and sour ginger won the title of famous agricultural products in Anhui Province, and Courtyard brand sweet and sour ginger won the title of characteristic agricultural products in Anhui Province. Ginger products are sold in surrounding counties and cities, supermarkets in some large and medium-sized cities and markets exported to the European Union. . Tongling ginger is famous all over the country for its "big skin, thin skin, more juice and less residue, and crispy meat". Tongling ginger is both edible and medicinal, and it is rich in nutrition. Tests show that it contains protein 1.4%, sugar 8% and fat 0.7%. In addition, it also contains essential nutrients such as calcium, iron, carotene and vitamin B 1. In medicine, Tongling ginger has the effects of strengthening stomach, stopping vomiting, promoting qi circulation, dispelling cold, resolving phlegm and detoxicating, sweating and relieving summer heat. Tongling gingko can not only accelerate germination, but also store ginger, which is unique. Its advantages are that during the incubation period, after heating and dehydration, the ginger skin is dried and shrunk, which reduces the free water in the ginger block, increases the temperature in the ginger block, promotes the activity of enzymes, continuously transforms nutrients, kills some germs attached to the epidermis of the seed ginger, and purifies the viruses in the ginger block, thus reducing the occurrence of diseases. In addition, the storage germination was successful once, and Jiangge stored ginger.

golden

Gold is one of the earliest metals discovered by human beings, before copper, tin, lead, iron and zinc. During the period of 1964, archaeologists in China discovered eight gold cakes from the Warring States period at the site of Dongyang Palace in Lintong County, Shaanxi Province, with a gold content of over 99%, which has a history of 2 100 years. In ancient Egypt, gold was also discovered very early.

silver

In ancient times, people knew about silver. Like gold, silver is a precious metal with a long history of application, which has a history of more than 4,000 years. Because of the unique and excellent characteristics of silver, people give it dual value of money and decoration. The pound and silver dollar used before the liberation of China were silver and copper alloys.

Edit this piece of copper

Copper is one of the metals known since ancient times. It is generally believed that the first known metal is gold, followed by copper. Copper is rich in resources and easy to process. Copper is the earliest metal used in human production. At first, people only used copper that existed in nature. Cut it with a stone axe and you can hammer it into various objects. With the development of production, it is not enough to use production tools made of natural copper. The development of production urges people to find ways to obtain copper from copper mines.

iron

Iron is one of the metals known since ancient times. Iron ore is one of the main components of the earth's crust. Iron is widely distributed in nature, but it was discovered and utilized later than gold and copper. First of all, the natural element iron is very rare on the earth, and it is easy to oxidize and rust. Its melting point (18 12K) is much higher than that of copper (1356K), and it is more difficult to smelt than copper. The earliest iron discovered by man was a meteorite falling from the sky. Meteorites contain a high percentage of iron, which is a mixture of iron and metals such as nickel and cobalt. Iron has always been regarded as the most mysterious precious metal when the method of melting iron ore has not come out and it is impossible for human beings to obtain pig iron in large quantities.

selenium

One of the sparse elements. Among the six known solid allotropes, three crystals (α-mono-italics, β-mono-italics and gray triangular crystals) are the most important. It also exists in the form of three amorphous solids; Red and black amorphous glassy selenium. The former is brittle with a density of 4.26 g/cm3; The density of the latter is 4.28 g/cm3. The first ionization energy is 9.752 electron volts. When selenium burns in the air, it will emit a blue flame and produce selenium dioxide (SeO2). It can also react directly with various metals and nonmetals, including hydrogen and halogen. It cannot react with non-oxidizing acids, but is soluble in concentrated sulfuric acid, nitric acid and strong alkali. Hydrogen selenide dissolved in water can precipitate many heavy metal ions into granular selenides.
