　　Product Introduction: Jiaozhu serves both as a bamboo shoot and bamboo variety, with the emphasis on shoots. Jiaozhu shoots contain nutrients such as protein, fat, sugar, phosphorus, calcium, iron, and various amino acids, and can be eaten fresh or processed. With low tyrosine content in the shoots, when canned, the broth remains clear, the shape is good, and the appearance is attractive, making it an excellent food product. In 1990, the Ministry of Forestry listed Shangyu County’s Jiaozhu propagation and high-yield techniques as a key forestry science and technology promotion project, and designated areas such as Changtang Township for establishing Jiaozhu production bases. Jiaozhu seedlings have been sold to over 10 provinces and cities including Jiangsu, Jiangxi, Fujian, Hunan, Hubei, and Shanghai.

　　Product History: Jiaozhu is a highly promising bamboo variety used for both shoots and bamboo, characterized by fast propagation, rapid growth, high yield, and wide applications. Our city is the origin of Jiaozhu. As early as over 700 years ago, during the Southern Song Dynasty, the Jiatai Huizhou Annals documented Jiaozhu. The Detailed Bamboo Record by Li # from the Yuan Dynasty noted, “Jiaozhu comes from the mountains of Yuezhou, similar to purple bamboo but lighter in color. It resembles a bull’s horn, hence the name, and is hard in texture.” Later, the Shaoxing Prefecture Annals of the Ming Dynasty’s Wanli era, as well as the Shanyin County Annals of the Qing Dynasty’s Kangxi, Daoguang, and Jiaqing eras, stated: “Jiaozhu has tall and sparse nodes, mild-flavored shoots, and spotted color.” This shows that the cultivation of Jiaozhu in our city has a long history, mainly produced in the mountains of Yuezhou (now around Shaoxing and Dongguan in Shangyu). Jiaozhu is primarily grown in Changtang, Zhangtang, and Changshan townships of Kuaiji County (now Shangyu County), as well as Tangpu Town. The Detailed Bamboo Record by Yuan Dynasty’s Li Yan recorded: “Jiaozhu comes from the mountains of Yuezhou, similar to purple bamboo, but lighter in color, resembling a bull’s horn, hence the name. It is hard in texture.” The Kangxi-era Kuaiji County Annals also said: “Jiaozhu has tall and sparse nodes, mild-flavored shoots, and spotted color.” By 1983, investigations by relevant departments found that Jiaozhu was mainly distributed in Changtang Township of Shangyu City, with small amounts also found in neighboring Zhangtang Township, Tangpu Town, Changshan Township, and Fusheng and Hongshan townships of Shaoxing County. The total area covered 150 mu (including 134 mu in Changtang Township). In recent years, under the leadership of the provincial forestry research institute, Shangyu County conducted systematic and comprehensive research on the economic traits, biological characteristics, and cultivation techniques of Jiaozhu. The research passed provincial evaluation and was awarded the Fourth Prize for Scientific and Technological Progress by the People’s Government of Zhejiang Province. The Ministry of Forestry listed Shangyu County’s Jiaozhu propagation and high-yield techniques as a key forestry science and technology promotion project, and established Jiaozhu production bases in places such as Changtang Township. To date, Shangyu County has developed nearly 1,000 mu of Jiaozhu. At the same time, Jiaozhu seedlings have been sold to over 10 provinces and cities including Jiangsu, Jiangxi, Fujian, Hunan, Hubei, and Shanghai, as well as to more than 30 cities and counties in the province such as Lanxi, Tiantai, Yuyao, Yongjia, and Anji.
