　　Fuchuan Yao Autonomous County is situated in northeastern Guangxi, within the citrus advantage industry belt of "Southern Hunan–Northern Guangxi–Southern Jiangxi" as defined by the Ministry of Agriculture. Its geographical coordinates are between 111°05′21″–111°28′50″ east longitude and 24°37′21″–25°09′20″ north latitude. The area enjoys a mid-subtropical monsoon climate with an average annual temperature of 19.2°C, extreme maximum temperature of 38.5°C, extreme minimum temperature of -4°C, and accumulated active temperature above 10°C totaling 6017.4°C annually. The average annual rainfall is 1699.7 mm, relative humidity is 75%, and sunshine duration averages 1573.6 hours per year. The frost-free period lasts 318 days. The soil is sandy red loam, deep, loose, fertile, well-drained, and rich in elements such as P, K, and Fe, with a pH value ranging between 5.5 and 7.5. Navel oranges are a variety of citrus, and Fuchuan has a long history of citrus cultivation. Historical county records still in existence from the 22nd year of the Qianlong reign (1757) and the 16th year of the Guangxu reign (1890) both document the planting of citrus and oranges. The 2005 Guangxi Famous & Quality Brands Record also features a special discussion on Fuchuan’s navel orange cultivation, as does The General History of China's Yao Ethnic Group. Navel oranges have become a major industry in Fuchuan, with all twelve townships in the county engaged in their cultivation. By the end of 2015, the total planted area reached 330,000 mu, yielding 224,000 tons with a total output value of 672 million yuan.

　　Name: Fuchuan Navel Oranges | Origin: Fuchuan

　　The growing region enjoys a subtropical monsoon climate with mild weather, abundant rainfall, and ample sunlight, with an average annual temperature of 19.2°C. Fuchuan State-Owned Lixin Farm in Guangxi currently produces 3,500 tons. The fruit is goose-egg shaped, vibrant orange in color, with crisp, tender flesh that melts in the mouth, juicy, and richly aromatic. High in Vitamin C, its color, aroma, and taste surpass other citrus varieties, earning it the title "Queen of Citrus."

　　In 1996, Newhall and Robertson navel oranges won gold and silver awards respectively at the China Agricultural Expo. In the same year, they were designated as a navel orange production base by the National South Asia Office. In 1997, they obtained the right to use the Green Food label, and in 2003, "Fu-" brand navel oranges were named Guangxi's high-quality famous product of 2002.

　　In 1981, Fuchuan introduced American navel orange seedlings from the China Citrus Research Institute. After years of careful cultivation, today’s Fuchuan Navel Oranges were born. In fact, many don’t know that the navel orange’s “settlement” in Fuchuan was accidental. One day in 1981, the China Citrus Research Institute in Chongqing imported 200 navel orange seedlings from the U.S., planning to relocate them to Fuzhou. The seedlings flew to Fuzhou Airport, took a brief breath—and then returned to Chongqing. What happened? Upon arrival, no one came to “welcome” them.

　　This incident left the China Citrus Research Institute feeling rather embarrassed. They decided to find new “homes” for the 200 American navel orange seedlings. After analyzing the climatic conditions of northeastern Guangxi, experts concluded that Fuchuan was also suitable for navel orange cultivation. So, the 200 seedlings boarded a plane again, this time flying to Guilin. Officials from relevant Fuchuan departments were thrilled and had been waiting at Guilin Airport. Upon receiving the “bride,” they immediately returned to Fuchuan and planted them at Lixin Farm without delay.

　　After planting, a count revealed only 197 seedlings—not the promised 200. It was later deduced that around three had died during transit. These 197 seedlings belonged to seven varieties: "Newhall," "Navelina," "Okitsu," "Washington" (i.e., Washington Navel Orange), "Frost," "Robertson," and "Ponkan." In the U.S., these were all premium varieties, but not all adapted well in Fuchuan. Some had low yields, others poor market appeal. For example, Ponkan navel oranges were too large for the domestic market. Newhall and Washington navel oranges, however, stood out due to their excellent quality, high yield, moderate size, and staggered harvest times, leading to their large-scale promotion in Fuchuan. Today, these two varieties dominate Fuchuan’s navel orange production.

　　After more than 20 years of effort, Fuchuan navel oranges grew from just 197 seedlings to a plantation scale of 182,000 mu by 2009—no one’s ever counted the exact number of trees. Another telling figure: in recent years, Fuchuan has produced over 800,000 navel orange seedlings annually.

　　Fuchuan navel oranges rose to fame in 1995, when they were “14 years old.” At the second Agricultural Expo hosted by the Ministry of Agriculture that year, three varieties—"Newhall," "Robertson," and "Ponkan"—won gold, silver, and bronze awards respectively.

　　The unique local soil and natural environment have shaped Fuchuan navel oranges, characterized by bright color, crisp and tender flesh, rich flavor, seedlessness, easy-to-separate segments, and soluble solids (mainly sugar content) as high as 13%–15%. Generally, fruits with over 13% soluble solids are considered sweet and refreshing. Additionally, their strong fragrance is another distinctive trait.

　　Over the decade following 1995, Fuchuan navel oranges continuously earned awards, not only domestically but also internationally. Notably, in October 2006, when over 95 samples from 30 counties across China’s four major navel orange production regions competed, Fuchuan’s Fu-brand navel oranges claimed first place and became the first in China to receive the title of “China Famous Agricultural Product.”
