Basic introduction of Xiangzhuzhu grape

Xiangzhuzhu thorn grape is a local characteristic variety, mainly distributed in Tongmu Town, Zhongfang County, Huaihua, with a planting area of 30000 mu. According to legend, when Emperor Qianlong went to Jiangnan, he tasted it and was greatly pleased with its dragon like appearance. He admired it and praised it as the "pearl of Hunan", hence the name "Xiang Pearl Thorn Grape". The grape has an oval shape, a black skin, pink and grayish white flesh, tender and juicy flesh, and a unique flavor

Hunan pearl grape, originally from Tongmu Town, Zhongfang County, belongs to the thorn grape population in botanical classification. It was initially cultivated in a courtyard style in front of farmers' houses, and has had strong market competitiveness in the past two years, rapidly developing to over ten thousand acres. This variety is planted for one year, begins to bear fruit in two years, and has a high yield in three years. During the peak fruiting period, the yield per mu should be over 3000 kilograms. Practice has proven that it is highly suitable for planting in high temperature and humid climates in the south. In 2002, Hunan Science and Technology Daily, Hunan Daily, Huaihua Daily, Southwest Market Guide and other newspapers all made relevant reports. In September 2002, Hunan TV's "Rural Discovery" program broadcasted a special program, causing a sensation. It is the best new grape variety for mountain development, farmland restructuring, comprehensive agricultural development, and cultivation in tourist attractions in the southern region

We all know about the Grape Valley in Turpan, and the Grape Valley in Tongmu Town, a Chinese county, is even more special, forming a grape corridor that stretches for 1 kilometer. The biggest difference between the two grape valleys lies in the grapes themselves. Even before human habitation, wild prickly grapes were growing all over the mountains and fields. In the Book of Songs and the Book of Southern Zhou, there are poems about the southern region having oak trees and Ge Xiaolei. Ge Xiaolei is a wild prickly grape produced in the southern region. Most of the grapes commonly seen in the market are imported from Europe and Asia, and prickly grapes are the domestically produced grape varieties native to China
