Introduction to geography

Huoshan Mountain is located in the hinterland of Dabie Mountain, which belongs to Tang Sheng County, Shouzhou, Huainan Road in ancient times. In Tang Dynasty, Lu Yu recorded that Huoshan produced tea. Li Zhao's Supplement to Tang Shi in the Tang Dynasty recorded: "Custom is precious to tea, and the famous products of tea benefit the public. ..... Shouzhou has the yellow buds of Huoshan. " Huangya is one of the nearly twenty famous teas in Tang Dynasty. In the Ming Dynasty, Wang recorded in the Book of Groups of Rooms that Huangya in Huoshan, Shouzhou was one of the best famous teas at that time. In the Qing Dynasty, Huoshan Yellow Bud was tribute tea, with an annual tribute of 300 Jin. Visible Huoshan Huangya famous for a hundred years. But after the evolution of the past dynasties, it was lost. Huoshan Huangya only knows its name, but not its tea. At present, Huoshan Yellow Duck has been created and resumed production on 1972. 1989 won the provincial quality award, 1990 won the Ministry of Commerce award, and in the same year won the Spark Science and Technology Award in the Seventh Five-Year Plan, and 1997 won the first prize of the third "China Teacup".

Origin environment

Huoshan Mountain Range is located in the west of Anhui Province, which is connected with Dabie Mountain at the border of Henan, Hubei and Anhui. The elevation of Baimajian, the main peak, is1774m. The county seat is famous for its mountains. The Dabie Mountains and Huoshan Mountains in the southwest of Huoshan County run through the whole territory from southwest to northeast, with high terrain in the south and low terrain in the north. Huoshan Mountain from southwest to northeast and Dabie Mountain from northwest to southeast have a sharp turn, commonly known as "Huoshan Arc". At present, the upper reaches of the Dongpi River in the "Huoshan Arc" above the Foziling Reservoir are the main producing areas of Huoshan yellow buds, mainly in Jinzhuping, Taiyang Township.

The "Huoshan Arc" along the northwest, west, south and southeast borders of Huoshan County constitutes a series of barriers connected by mountains, forming a periphery higher than the central hinterland, and only the dam area of Foziling Reservoir is a long and narrow canyon mouth. The "Huoshan Arc" is 800 meters above sea level in Zhongshan District, with high mountains, steep slopes, deep valleys, cold winters and few tea trees. The branches and shoulders at an altitude of 400-800 meters are suitable for growing tea, and high-grade Huoshan yellow buds are mostly produced in this area. The low mountain valley basin in the upper reaches of the Dongpi River is an important producing area of Huoshan yellow bud (also known as Huoshan tea), with thick slope and fertile land, and there are Foziling and Mozitan reservoirs to regulate the climate. Huoshan County's land span is 3 1 degree -3 1 degree-3/minute east longitude 1 15 degree 55 minute-1 16 degree 43 minute. It belongs to the north subtropical humid monsoon climate zone, with four distinct seasons, moderate heat and cold, great regional differences and great vertical changes.

Annual average temperature 15. 1℃, July average temperature 27.87℃,1October average temperature 2℃. There are few hot summers and winters, and the duration is not long. ⊙0℃ lasts for 336 days, and the annual accumulated temperature is 4700℃. The drop rate of maximum temperature with altitude is larger than usual, especially in summer, which can reach 0.7-0.8℃/ 100 m, and it is cool in summer in mountainous areas. There is often obvious inversion below 800 meters in mountainous areas. The high temperature weather at ≧35℃ in Chengguan lasts for 23 days, but the vertical decline rate is large, and there is almost no high temperature weather in mountainous areas above 500 meters.

The annual average radiation is 488. 18 kJ/cm2, the annual sunshine hours are 2 000-2 200 hours, and the annual sunshine rate is 47% (53% at most and 40% at least in history).

Precipitation Annual precipitation 1, 1, 000- 1, 600 mm, general altitude1000 m, average precipitation 60-70 mm, precipitation in the mountain is more than that outside the mountain. The precipitation in spring and summer accounts for about 70% of the whole year, and it is less in autumn and winter.

The relative humidity is 80% all the year round, and ≧80% of the days in the whole year are around 200 days, with less low humidity and dry weather.

The total number of foggy days in the whole year is about 24-33 days, and there are more in the mountains than outside. According to the observation of the county meteorological bureau, the annual precipitation of Baijiashan (the origin of genuine yellow buds) in Dahuaping Town, which is 500 meters above sea level, is 1.8 1.8 mm, and the average annual foggy days are 1.8 1 day.

Yellow brown soil is widely distributed in middle and low mountainous areas and hilly areas, mostly acidic and weakly acidic (pH5-6.5), with coarse yellow brown soil accounting for 96.84%. The soil-forming parent material is the residual slope deposit of weathering of various rocks, and the soil is in the early stage of development, with the characteristics of "coarse bone" and "thin layer" (it belongs to large gravel soil, and the soil layer is mostly less than 30 cm), with good permeability, poor fertility preservation and wide adaptability. According to 1984 soil survey, the average contents of various nutrients are: organic matter 2.5%, total nitrogen 0. 12%, available phosphorus 1 1 mg/kg, and available potassium 86 mg/kg.

Huoshan Yellow Bud is mainly produced in Dahuaping Town, Jinzhuping, Jinjishan, Huoshaoling, Jinjiawan, Wumijian, Mozitan and other places in the mountainous area above 600 meters above sea level in Huoxian County. Here, the mountains are high and the clouds are light, the rain is abundant, the air relative humidity is high, there is much diffused light, the temperature difference between day and night is large, the soil is loose, the soil is fertile, the PH value is about 5.5, the forest and tea are flourishing, and the ecological conditions are good, which is extremely suitable.

Output data

No yield data of yellow buds in Huoshan before liberation was found. In 1970s after liberation, state acquisition began, and the output of 1978100 kg and 198 1 year rose to 306,638.

Huoshan yellow bamboo shoots originated before the Tang Dynasty. In Tang Shi Supplement by Li Zhao in the middle Tang Dynasty, Huangya of Huoshan Mountain in Shouzhou was listed as one of the famous teas, and there were fourteen tributes. Huoshan Huangya is a kind of cake tea in Tang Dynasty. Tang Yang Ye's "Chef's Handmade Gold Record" states: "There is a small group of Huoshan Mountain in Shouzhou, which may be a small piece of dragon bud as a tribute, and the number is very small. In ancient times, it was said that the yellow buds of Huoshan took one flag and one gun. The ancients described it as an armor with leaves as soft as cicadas' wings, which is a kind of stress-free loose tea. "

"Historical Records" said: Shouchun Mountain has yellow buds, which can be cooked and drunk, and are immortal for a long time. Liuhuo's old birthday and spring also died. A kind of fairy bud, also known as Shouzhou Huoshan yellow bud. Xiao Chun in Lu 'an Prefecture is the best tea, and it was paid tribute in the Ming Dynasty. Since the seventh year of Hongzhi, Huoshan County and prefectures and counties have been set up separately. The situation of county-level buyers should be remitted to the state general manager.

There are 200 bags of kungfu tea in Lu 'an, each bag weighs 12 Liang. Since the establishment of Huoshan County in the seventh year of Hongzhi in Ming Dynasty, it has been divided into 25 bags of tea for the state and 0/75 bags for the county. ...

Because of this, Kangxi provided an extra 100 bags in the 23rd year, including 37 bags in the state and 263 bags in the county, accounting for 460 kilograms and 420 taels. Every year, the state prepares to send the county to buy monochromatic bud tea at a price. ...

There are hundreds of tea-producing areas today, and only a dozen tributes have been made. In the Ming Dynasty, it was dedicated to Lu 'an, and the rest was decided by the city. There are as many as 360 letters a year, and there are secondary seals to make up. The state is less than two, which is the strength of Huo Bei, and six enjoys its success. -"Huoshan County Records Gongcha" Qing Shunzhi seventeen years

Historical origin

tea

Tea is the highest in mountain products. The top name is Silver Needle (only one shot is taken from the top of the branch), followed by Que Tongue (micro-exhibition of two leaves taken from the top of the branch), Plum Blossom (the tenderest leaf is selected), Orchid Head (three or five leaves taken from the top of the branch) and Pineapple (imitating the method of Huizhou tea, but taking Huizhou as the leaf and Huo as the whole leaf). They are all picked by hand, and they are all expensive before the rain. Its natural branches are the best, called Maojian, with names such as Gong Jian, Ruijian, Before Rain, After Rain, Dongshan and Xishan (the branches grow up after rain and taste better than before rain in Dongshan). There are several kinds of lotus branches, including An Baili, Quancheng Red, Quancheng Green, Lvlian and Cheren, all of which are classified by age. When the tea leaves are too old to be picked carefully, it is the first tea whose perennial leaves are brushed over. By the beginning of May, a new stem had sprouted, the leaves were bigger and thicker than the first tea, and the taste was slightly astringent. The price is less than half of the first tea, and it is for children.

Records of historical records

"Historical Records" said: Shouchun Mountain has yellow buds, which can be cooked and drunk, and are immortal for a long time. Liuhuo's old birthday and spring also died. A kind of fairy bud, also known as Shouzhou Huoshan yellow bud. Xiao Chun in Lu 'an Prefecture is the best tea, and it was paid tribute in the Ming Dynasty. Since the seventh year of Hongzhi, Huoshan county, prefecture, county and county have been set up separately, and the purchase case of county households should be remitted to the state general manager.

Lu 'an Local Records and Products

-eleven years of Tongzhi in Qing dynasty, Lu' an government records and products.

Tea ranks first in the commodity category. Chashan has all kinds of environments. Generally speaking, the mountains are high and foggy, and Li's products will be excellent. With its elegant atmosphere of heaven and earth, there are occasionally a few hanging stones, which are particularly fresh and unique and do not need artificial cultivation. Therefore, the fog in Nanxiang is very thick, hanging around Jianlongshan, and the output is the highest in a city, which is both exquisite and twice as expensive as other towns and villages. Tea merchants buy on the spot, women workers sort out colors and distribute them, and transport them to Suzhou in big baskets. Su Shangxun used Zhu Lan and Jasmine to move from the inland to Yingkou, which was distributed in three northeastern provinces. Some have recently been made overseas with the emblem. Next, it was shipped to Bozhou and Zhoujiakou in the north, and the semi-smoked jasmine was resold to Kyoto, Shanxi and Shandong, while Xixiang was west of Tuziling, where the tea was thicker, slightly bitter and coarse, and the branches were not refined. Tea merchants in Qingqi were all bought from Dahuaping and Wuxi River and sold all the way to Shandong. To the north of the Buddhist temple, a few treasures were transported to the state by natives, bought by western businessmen, baked by themselves and sold to Shanxi, Outer Mongolia and other places. Jiubao in the extreme west is very small and tastes bad. Most of them are bought by Hubei people. All kinds of flowers listed in the previous records: such as silver needles and finches, tea began to sprout; Plum blossom slices, blue heads and songluochun are the first leaves of tea; Small tea, the price is several times, it is difficult to collect, so it is only sold in the vicinity of the city, Liulin River and Zhufo Temple, and most of them are sold in Kyoto. The climate in the southeast is slightly warmer, so it can be picked in front of Grain Rain, hence the name Maojian before the rain. After the Grain Rain in the Western Hills, the mountains can only be cut, picked once every few days, and harvested on the twentieth day. So there are head, two, three and four roads. Finally, it is common for people to pick from perennial leaves and turn them into Kelao tea. Spring tea is finished, and new seedlings are revived in May and June, which is called zicha. Its dry and flat taste is slightly astringent, and the price is also reduced by half. However, those who cherish tea trees will never pick them, and the next spring tea will flourish.

Another kind of Kuding tea, although called tea, is actually woody, with branches and leaves as big as tea. There are two kinds: a leaf with thorns on it; One leaf is big and round, all naturally occurring among rocks in the deep mountains, and there are no seeds. It is harvested at the same time as tea. Bitter taste, extremely cool nature, can be used as medicine. In recent years, tea merchants like to buy, and villagers are gradually looking for species, which is extremely difficult to plant.

"natural history"

People who drink real tea make people sleep less.

Pan Zhi

Lu 'an Tea, made with Huofu, is named after Lu 'an. When Huo did not build the county, he had already paid tribute, which was a new one. "Apocalypse" was named after Lu 'an Village (real name is 60,000 Village, mistakenly called Lu 'an). There are many mountains in ancient Huoshan, and six places are spacious and spacious. Tea production floats in Huoshan, but it is not as good as two. Huang Zhi, a county-level tea maker and a state-level tea maker, said he was afraid to help others. But Dongshan is the place where tea is born prematurely. Dongshan belongs to the state. Every year Dafu recommends tribute from Xinxian County, and all citizens go to the county to sell it before it rains. Huo was produced in the southwest, and it was late after the rain, so it was not as good as a tribute, so the proper name of tea was Lu 'an, and it was also recorded in the literature.

Wu zhi

The natives don't know the taste of tea, so Yan Chyi Yu Chu uses it for daily use. Every other year, after a thousand miles of capital, the investment bank pre-examined. Teeth have been wronged by all Jiazi mothers, and tea farmers cut them all the time to make up for it: silver is melted and turned into a low color; The scale is arbitrary; The price is getting lower and lower, and there are more sample teas. Tea farmers can't compare; Although repeated education, detailed application of various constitutions, strict investigation of rural insurance, tea farmers are a little clean and affordable, but the disadvantages have not been eliminated. Although tea makes money, it works hardest: picking it every day, frying it at night, and not resting on your pillow for ten days. We need to hire a guest worker because we are short of manpower. Tea is worth a little more, but it can still be compensated. After the army was revived, donations became more and more expensive. When the cost of a business is heavy, it will reduce the value of people. Recently, the number of merchants has gradually increased, and there are Huiyuan tea merchants, whose estimated value dominates the market. When merchants buy old leaves, tea merchants can make excuses, so the price of tea is getting lower and lower. Since Guangxu, a catty of silver has not exceeded money, and when it is cheap, it will cost 70 to 80 cents. What is lacking is civilian welfare. Near Huizhou county, imitating foreign countries, baking with machines is precise and economical, which is quite beneficial. If local gentry and businessmen can gather shares, set up companies and make fine work, then the power will be exercised by me, and all the disadvantages will inevitably be eliminated. West Renye Fang said: Huo Cha smells better than Huizhou.

Farmers in this county pick the best before the rain, and the new shoots are shot with one flag. They are made according to law, sealed with yellow silk bags, and four boxes of * * * are prepared with dragon flags and dragon symbols.

Health function

Reduce fat and lose weight

Yellow bud is a kind of non-fermented natural tea, which retains the natural substances in fresh leaves and is rich in amino acids, tea polyphenols, vitamins, fatty acids and other beneficial components. Tea polyphenols can remove cholesterol accumulated on the arterial wall and inhibit the uptake of low-density lipoprotein cholesterol by cells, thus achieving the purpose of reducing blood lipid, preventing and buffering arteriosclerosis.

be radio-resistant

Computer radiation not only harms our health, but also affects the quality and efficiency of work. People who often use computers can drink yellow bud tea to supplement specific plant nutrition and eliminate dark circles caused by computer radiation. The concentrated tea polyphenols contained in yellow buds can inhibit the damage caused by free radicals to skin supporting fibers, which is recognized as the most effective anti-free radical factor at present. Yellow shoots contain effective components of radiation protection, mainly tea polyphenols, lipopolysaccharide, vitamin C, vitamin E and some amino acids. Its mechanism of action is also aimed at detoxification of a large number of free radicals caused by radiation and poisoning caused by peroxide. Tea polyphenols can resist oxidation and scavenge free radicals, so as to achieve the effect of radiation protection and play the role of radiation protection agent.

Protecting teeth and improving eyesight

The basic components of tooth tissue are fluorine, phosphorus and calcium, which make teeth smooth and hard, acid-resistant and wear-resistant. The fluorine content of yellow bud tea is high, about 75- 100 mg per kilogram. Therefore, drinking tea regularly can absorb enough fluorine to meet the human body's demand for fluorine, which is conducive to protecting teeth and strengthening teeth. Moreover, tea can also prevent dental caries. Because the human body's ability to prevent caries is related to the fluorine content in the hard tissue of teeth. Drinking yellow bud tea or gargling with tea is an effective method to prevent and treat dental caries.

Anti-aging and longevity

There is no doubt that yellow buds can make women more beautiful! Yellow bud is not only rich in vitamin C, but also contains flavonoids, which effectively increases the antioxidant effect of vitamin C. The combination of the two can be said to have a rare effect on maintaining skin whitening.

Refreshing.

Yellow bud contains a proper amount of caffeine, and its disadvantages can't be exerted in the body because of the existence of thearubigins, but a proper amount of skeletal muscle can accelerate the contraction of skeletal muscle and excite the central nervous system. In addition, the volatile oil in tea is fragrant and refreshing, which has the effect of refreshing the brain. After intense work and labor, drinking a cup of yellow bud tea can refresh the spirit and relieve fatigue; Drinking a cup of yellow bud tea at work can improve the curative effect.

Enhance immunity

The human body has its own immune function to resist the invasion of foreign microorganisms and maintain health. This immune defense system recognizes pathogens invading human body through the formation of immune protein group, and then produces antibodies and macrophages from white blood cells and lymphocytes in human body to perform the task of panic attack. Drinking tea can increase the number and activity of white blood cells and lymphocytes in human body, promote the formation of interleukin in spleen cells, and thus enhance human immune function.

Help digestion and improve the stomach.

Catechins in Huoshan Huangya tea have the following four functions of eliminating bad breath: ① eliminating methyl mercaptan, a bad breath substance in the mouth; (2) combining with matrix amino acids of oral bacteria; ③ It has bactericidal and bacteriostatic effects on bacteria in oral cavity; ④ Purification of enzymes in oral saliva.

Drinking Huoshan Huangya tea can eliminate bad breath on the one hand and help digestion on the other. This is because tea contains aromatic substances, which can not only secrete gastric juice, help digestion and absorption, but also eliminate the scale in the stomach and relieve symptoms such as dry mouth and bad breath.

As an alkaline beverage, the minerals in yellow buds can neutralize acidic foods and keep the normal pH of human body fluids (slightly alkaline), thus helping people stay away from "sub-health" and "rich diseases". In addition, the tannins in yellow bud have the function of membranous bacteria, and caffeine can enhance the secretion of gastric juice and help digestion, so drinking yellow bud tea often can also have strong gastrointestinal function.

Produce body fluid to quench thirst and relieve summer heat.

"Tea Spectrum" records that "people can quench their thirst by drinking real tea". "Daily Compendium of Materia Medica" records that tea can "relieve trouble and quench thirst". In Sun Da Slo's Collection of Tea Spectrum, he said, "Relieve boredom and thirst, turn into a thin man, and tea and tea are beneficial." As we all know, drinking tea can quench your thirst. In the midsummer heat, a cup of green tea is full of saliva. Tea soup not only supplements water to human body, but also has obvious thirst quenching effect because polyphenols, free sugars, amino acids, vitamin C and saponin compounds in tea react with saliva in oral cavity.

Tea is also a drink for clearing away heat and fire. Li Shizhen, a famous medical scientist in ancient China, wrote in Compendium of Materia Medica: "Tea tastes bitter and cold, and the yin in the yin is heavy. Li Zhaojian can best reduce the fire, for all diseases, the fire will be clear!" From the perspective of Chinese medicine, tea, especially green tea, is a cool food that can clear fire.
