1904 New Zealand introduced kiwifruit from Yichang, Hubei, China for domestication and cultivation. Cangxi kiwifruit was bred in 1924 (this variety still accounts for more than 95% of China's overseas cultivation area and 20% of China's cultivation area). 1930 began to be commercialized, and 1952 was successfully exported to Britain.

Opening up the European market, driven by the high profit of 1970, New Zealand began large-scale commercial planting, which immediately triggered a worldwide commercial planting fever of kiwifruit until 1990. After more than 90 years of development, it has formed an international industry, with a planting area of about 65438+ 10,000 hectares and a total output of 1 10,000 tons.

People in Cangxi Kiwifruit Mountain are called "carambola", also called "base fruit" and "rattan peach". In the Ming Dynasty, Li Shizhen made the following explanation: "Its shape is like a pear, its color is like a peach, macaques like to eat, and it is called kiwifruit." Cangxi Kiwifruit is a famous specialty in Zhangjiajie. Every time it matures, it is all over the mountains, and you can easily pick it when you walk into the mountains.

The general name of plants with certain genetic material and valuable for kiwifruit production and breeding. Kiwifruit plants are mainly native to China. Southwest China has the most species and is the distribution center of this genus. 57 species, 42 varieties and 6 forms of Actinidia have been discovered in China, and the germplasm resources are very rich.

According to the requirements of these species for ecological environment, they can be roughly divided into three categories: cold tolerance, temperature tolerance, high temperature tolerance and high humidity. Cold-resistant varieties include Actinidia arguta and Actinidia arguta. Warm-loving varieties include Chinese kiwifruit and delicious kiwifruit. High temperature and high humidity resistant varieties include kiwifruit and Cangxi kiwifruit.
