1, the origin of Wancheng Kudingcha
Wancheng Kuding Tea is one of the world famous teas in China. According to Lu Yu's "Tea Classics-Source" in the Tang Dynasty, "Southern tea makers are the best. Its trees are like melon dew. " "Compendium of Materia Medica" written by Li Shizhen in Ming Dynasty records: "Gao Lu, whose leaves are like tea, is widely used today and is called Kuteng. "According to domestic experts' research, it was called' Gao Lu' or' Gualou' tea in ancient literature, which is today's Kuding tea; The old edition of Cihai notes: "Kudingcha, a famous specialty tea in Guangxi, is produced in Kudingcha Township, daxin county", which is now Kudingcha Village, Longmen Township, daxin county. All dynasties are famous, both at home and abroad. So far, the market of folium isatidis is broad. Although it is expensive, it is still favored by compatriots in Hong Kong and Macao, overseas Chinese and foreigners.
There used to be six mother trees in Ku Ding Cun, but now there are five. The largest one is 28 meters high and DBH 79 cm. The two became one and flourished for a while, with a crown of 1.44 square meters. According to Lu Huankui, the owner of tea tree (Laoxi):
"This Kuding tea tree was planted by Lu Youyu, the granddaddy, and has lasted for five generations". 199 1 produces about 35 kg of dry tea, 260 yuan/kg; Tea fruit is 380 kg, 100 yuan/kg, and the output value of that year is 47,000 yuan, which is well known. When spring tea is on the market or the tea fruit is ripe, merchants from all walks of life come from thousands of miles and come in an endless stream, so it is called "Green Huang Jinshu".
Wancheng Kuding Tea was once a tribute of the emperor.
According to legend, from the middle of the Ming Dynasty, Wancheng Kuding tea was sent to the capital as a tribute to the emperor every year, but there were not many sources of Kuding tea, or there were different varieties, and the quality of tea was obviously different from that produced by Kuding tree. Quality products are decreasing year by year. In order to increase the number of tributes, the state palace ordered the villagers to collect thousands of tea seeds for breeding and expand the planting area to increase production. Kewancheng tea tree is a deep dormant tree species. In the feudal society where agricultural production technology was extremely backward, it failed after many experiments and breeding. Only by the output of several original tea trees each year, the tribute can not be guaranteed, nor can it meet the needs of local officials' families. To this end, the imperial court sent imperial envoys to Taiping Prefecture (now Chongzuo County) in Guangxi many times to trace the tribute of Kudingcha. The owner of Wanchengzhou knew that this matter was serious and he might be killed, so he thought hard about how to prevaricate. After repeated discussions, Kuding tea tree, which happened to die in Ku Ding Cun, was sent to Taiping House, pretending that Kuding tea tree had died and could not complete the tribute. The imperial envoys and the master of Taiping House believed it and reported the death of the tea tree to the court. Since then, the history of Wancheng tea as a tribute has ended, and local officials have been exempted from asking questions.
