"Fuchuan navel orange" is characterized by bright color, crisp meat, rich flavor, no nucleating slag, soluble solids (mainly sugar content) as high as 13% to 15%. In general, more than 13% of soluble solids are sweet. In addition, it smells very sweet and is another sex of Fuchuan navel orange.

China's navel oranges have four major producing areas: Jiangxi Minnan, Chongqing-Hubei, Xiangnan-Guibei, and Zhenan-Fujian. The Fuchuan navel orange belonging to the Xiangnan-Guibei producing area started late. Fuchuan is a typical subtropical monsoon climate with mild climate and abundant sunshine. The annual average temperature is 19°C, the annual maximum temperature is 38.5°C, the extreme minimum temperature is -3°C, and the accumulated temperature of activity ≥10°C is 6072°C. The rainfall is abundant. The rainfall is 1700 mm and the annual relative humidity is 75%. The unique land resources and natural environment have created Fuchuan navel orange. Fuchuan navel orange is characterized by bright color, crisp meat, rich flavor, no nucleating slag, and soluble solids (mainly sugar content) as high as 13%~15%. In general, more than 13% of soluble solids are sweet. In addition, it smells very sweet and is another sex of Fuchuan navel orange. The "life experience" of Fuchuan navel orange is very simple: in 1981, Fuchuan introduced American navel orange from the China Citrus Research Institute. After years of careful "care", it has made today's Fuchuan navel orange. In fact, many people do not know that the navel orange "home" Bucheon is accidental. One day in 1981, the China Citrus Research Institute in Chongqing introduced 200 strains of navel orange seedlings from the United States and planned to “marry” fruit seedlings into Fuzhou. The batch of fruit seedlings arrived at Fuzhou Airport by plane. After a short breath, they returned to Chongqing. What happened? It turned out that the fruit seedlings arrived at the airport, and no one actually "greeted the family." This kind of thing makes the Chinese Citrus Research Institute "very faceless." The China Citrus Research Institute decided to re-see the 200 US Navel Orange Seedlings. After analyzing the climate of the northeastern region of Guangxi, experts from the China Citrus Research Institute believe that Fuchuan is also suitable for navel orange cultivation. In this way, 200 US navel orange seedlings re-boarded and flew to Guilin. The staff of the relevant departments in Bucheon were very excited. They had already waited at the airport in Guilin. They immediately returned to Fuchuan after receiving the "bride" and planted them in Fuchuan Lixin Farm for the first time. After the seedlings were planted, there were only 197 strains, not 200 of the Chinese citrus research. Later, the reason for the analysis was probably that three fruit trees died during the transfer. There are 7 varieties of these 197 fruit seedlings: "Newhall", "Navelina", "Dasan Island", "Hua Navel" (ie Washington Navel Orange), "Frost", "Robertson", "Ponna" ". In the United States, they are all excellent varieties. After coming to Fuchuan, they are not all adapted. Some of the production is very low, and some markets are not optimistic. For example, the "Ponna" navel orange has a large fruit shape and is not easy to sell in the domestic market. "Newhall" navel orange and "Hua Umbilical" are mainly promoted in Fuchuan due to their good quality, high yield, moderate fruit shape and wrong time to market. At present, Fuchuan navel orange is mainly these two varieties. After more than 20 years of hard work, Fuchuan navel orange has grown from 197 plants in the district to the planting scale of 182,000 mu in 2009. As for how many plants there are, no one has ever counted them. Another figure can be seen: In recent years, more than 800,000 navel orange seedlings have been cultivated each year in Fuchuan. In the more than 10 years since 1995, Fuchuan Navel Orange has won awards in succession, not only domestic but also international. It is worth mentioning that in October 2006, 95 samples from more than 30 counties in the four major navel orange producing areas of the country were sent to participate in the competition. Fuchuan’s Fujiang brand navel orange won the first place and won the title of “China Famous Brand Agricultural Products”. . In 1996, Newhall and Robertson Navel Orange won the gold and silver awards respectively at the China Agricultural Expo; in 1996, they were designated as the navel orange production base by the National South Asian Office; in 1997, they obtained the green food mark; in 2001, the international agricultural and agricultural achievements of Thailand In the product promotion fair, the company won the gold medal for outstanding products. In the same year, the China Green Food Center approved the use of green food labels. In 2003, “Fujiang” navel orange was awarded the 2002 Guangxi Famous Brand Quality Product. In 2004, the National Non-polluted Fruit Production Demonstration Base County was established and the pollution-free production area was approved. In 2005, among the 22 seasonal fruit quality evaluations of Guangxi organized by the Agriculture Department of the Autonomous Region, Fuchuan Navel Orange ranked first; 2006 u0026quot;Fujiangu0026quot; The brand navel orange won the title of China's famous brand agricultural products; in 2008, it was listed as the fruit of Daqing in the autonomous region; in 2009, it was selected by the State Administration for Industry and Commerce and the Trademark Office to obtain the Fuchuan Navel Orange Geographical Indication Certificate.
