Hashimoto Citrus-Variety History

As early as the Song Dynasty, Ougan had a "milk orange" with few or no seeds. "Qunfangpu" contains: "Citrus comes out of Mud Mountain (now Cangnan Yishan) for the most, and its taste is like cheese, hence the name. Its wood is swaying, its leaves are slender, its flower rhyme is round, its skin is wax-like, its size is six or seven inches, its skin is thin and delicious, guanidine does not stick to the petals, and it can't eat without me. One has only one or two cores, and there is no fragrance. People are the best in oranges. " Chao Pu has a compliment: "Wenjiang is a different fruit, and Mud Mountain is expensive. Mail is sent thousands of miles south of the Yangtze River. The weather is half cold and half bright. Fog, once afraid of Wu Ji. Fortunately, give it to me, how can green oranges compare with yellow oranges? " Unfortunately, in ancient China, the "milk orange" was not cultivated into a seedless "Satsuma orange". The process from the spread of orange to the return of Wenzhou Mandarin to the old country is quite legendary. Today, Satsuma mandarin is the most prosperous member of the citrus family. It can be seen everywhere from Taiwan Province Province, a treasure island, to Tibet on the plateau, from the foothills of Wuzhishan Mountain to Hanzhong Basin and even around the world.

/kloc-At the beginning of the 5th century, a Japanese monk named Zhihui went to the Tiantai Xiaoguo Temple in China and returned to China by boat via Wenzhou. While in Wenzhou, he tasted delicious oranges and took several baskets of oranges back to Changdao Village Temple in Kagoshima, Kyushu, Japan. After sharing the food, the monks in the yard threw oranges in the garden at will. Unexpectedly, the oranges sprouted and grew seedlings the next spring. A few years later, the citrus seedlings grew into trees, blossoming and bearing fruit. Later, among these citrus trees, it was found that one citrus was seedless, so the grafting method was improved several times and finally a new seedless citrus variety was cultivated. Because it comes from Wenzhou mandarin orange, it is named "Wenzhou mandarin orange", which is widely planted in Japan and exported to foreign countries.

Mandarin oranges had lived in Japan for more than 400 years before returning to China to settle down. According to the ninth edition of Ruian Literature and History, about 19 1 1 years ago, Ruian Farmers' Association entrusted Xu Xuan, a Japanese student studying in China, to introduce improved fruit trees. Xu Xuan, a native of Ruian, studied agriculture at Imperial University in Tokyo, Japan. 1965438+When I graduated and returned to China in 2003, I bought Wenzhou seedless orange seedlings near Tokyo and brought them back to Rui 'an to improve mandarin orange. This is the first time that mandarin oranges have returned to their hometown. During the period from 19 16 to 19 17, when Mr. Huang Shuochu of Pingyang returned from Japan, he also brought back Wenzhou mandarin seedlings from Xingjinyuan, Japan and Daocun, Kawabe County, Hyogo Prefecture, and planted them in Zhenglou, Pingyang, Jiusan Lake in the suburbs and Jiangjunqiao. Since then, it has gradually expanded and become a new variety of citrus. It is said that there are second-generation old trees in the area. 65438+In the early 1930s, Miao merchants in Zhejiang and Hunan introduced some improved varieties of mandarin oranges from Japan, but there were still original mother trees in Huangyan and Shaoyang. 1956, Citrus Research Institute of Chinese Academy of Agricultural Sciences introduced a new strain of 12 mandarin orange from Japan for many times, and made scientific research and achieved gratifying results.
