Kiwi is an ancient plant. In 1977, the Nanjing Institute of Geological Palace of the Chinese Academy of Sciences found several kiwi leaves fossils in Tiandong County, Guangxi. It was analyzed as early and new fossils, which has been 26 million to 20 million years ago. kiwi native to my country. "The Book of Songs" 2500 years ago: "There are 苌 2, 猗傩 猗傩; The local kiwi grows, and its branches sway with the wind softly, and its flowers and fruits are beautiful.

In in the country, kiwi cultivation has a long history, but it has not attracted enough attention and has a late history of intensive cultivation. In 1957, Nanjing Botanical Garden observed biological characteristics of Chinese kiwi seedlings. In 1958, the former Northwest Agricultural College introduced the fruit tree test station from the northern foot of the Qinling Mountains for the preliminary successful cultivation of the scaffolding. In 1957 and 1961, the Institute of Plant Research of the Chinese Academy of Sciences was introduced from Taibai Mountain in Qinling and Henan Province to the Funiu Mountain in Henan Province to speculate the delicious kiwi and Chinese kiwi to the Beijing Botanical Garden. Peach, dog jujube kiwi, and Ge Zao Moncel. In 1978, the National Kiwi Science Research Cooperation Group was established, mainly engaged in research on resource survey, variety selection, cultivation technology, processing and storage of freshness, medical care, and medical care. By 2002, there were basically 61 species, 43 variants, and 7 variants of the native kiwi genus plants in my country. Basically, 27 provinces, municipalities, autonomous regions (except Xinjiang, Qinghai, Ningxia) were found. Clarify the ecological environment, horizontal distribution, vertical distribution, accompanying plants of the kiwi distribution area, and give more detailed descriptions of species, variants, and variants. In 1991, my country's kiwi entered a period of rapid development. In 1993, the cultivation area was about 11,500 H square meters, with an output of 9,000 T. By 1995, it had an area of 29,100 H square meters, ranking first in the world, with an output of 89,000 t, ranking fourth in the world. It is estimated that at the end of 2002, the cultivation area exceeded 450,000 H square meters, with an annual output of about 200,000 t, accounting for about 1/5 of the world's total output. At present, Shaanxi, Henan, Sichuan, Jiangxi, Zhejiang, Hunan, and Anhui have become the main production bases for my country's kiwi. In abroad, the Royal Society of the British Institute began to collect kiwi specimens from my country in 1847, and began to cultivate cultivation in 1900. The United States cited kiwi in 1904. In 1906, New Zealanders cited kiwi from our country. In 1930, Alison, Bruno and others cultivated new varieties. In 1937, commercialized production began in the frost -free zone, and the bird "Kiwi" of New Zealand's specialty bird "Kiwi" was used as the name of the kiwi. The cultivation area is 122,000 h square meters, ranking third in the world, with an output of 270,000 t, ranking second in the world. New Zealand kiwi is exported to more than 20 countries such as Europe and the United States, and almost monopolized the entire international market before the 1980s. In 1909, Russian gardening scholar Miqiulin introduced wild kiwi seeds and plugs from my country, using superb grafting technology to cultivate five new kiwi varieties. The main varieties planted in northern Soviet. In addition, Italy, Greece, Japan, France, etc. have a large amount of kiwi cultivation.
