Ignorant fire belongs to the genus Citrus in Rutaceae, which is the scientific name of ugly orange (ugly orange or ugly orange), also known as mixed orange and convex-topped orange (different from citrus in spring, citrus in green and citrus in wogan). Ignorant fire is the earliest variety introduced from Japan. After being cultivated in Japan for more than 40 years, it was introduced to Sichuan Province in 2000, and it was also planted locally in Meishan, Ziyang, Neijiang, Jintang, Chongqing, Yunnan, Jiangxi, Hunan and Zhejiang.
Cultivation precautions
Because the cold tolerance of fruit is weaker than that of satsuma mandarin, and the fruit must mature in the winter on the tree, the average annual temperature in the cultivation area must be above 16.5 degrees, and the minimum temperature below-3 degrees before harvesting should not last too long.
Pericarp is brittle and prone to storage diseases, such as water rot and brown spot disease. In summer and autumn drought years, although the sugar content of fruit juice has increased, the acid reduction is slow, so irrigation should be done in time in autumn drought. Because I don't know that the potential of the fire tree is weak, in order to maintain the potential of the tree, if the seedlings are planted with bitter orange rootstock and the strong rootstock is used for root grafting, it is suggested that the high grafting should be carried out on the Xia Gan Guaisheng tree.
1 month (varies from region to region). Fruits with water rot should be harvested immediately. In order to prevent the occurrence of water rot fruit and the protrusion of fruit stalk. To improve the quality, it is recommended to use greenhouse and greenhouse to be cultivated in facilities.
