　　The History and Origins of Deqing Gonggan

　　Historically, the cultivation of Deqing Gonggan began during the Kaiyuan era of the Tang Dynasty, dating back over 1,300 years. Records indicate that during the Shaoxing era of the Song Dynasty, Emperor Gaozong of Song visited Deqing Prefecture and praised the local citrus after tasting it. Since then, Deqing citrus has been regarded as a royal tribute, giving rise to the name "Gonggan" (tribute citrus). Experts have confirmed that Deqing Gonggan is a natural hybrid of oranges and mandarins, combining the attractive appearance, golden color, and rich flavor of oranges with the tender, smooth flesh, easy-to-peel skin, seedlessness, moderate sweetness, and juiciness of mandarins. Its taste is exceptional, with a refreshing sweetness reminiscent of pomelo. It embodies the best qualities of sweet oranges, sugar mandarins, and honey pomelos. Research by geoeconomic scholars shows that Deqing County’s mild climate and unique environment are ideal for Gonggan cultivation. The key quality traits of Deqing Gonggan include: **Golden-Yellow Color** – Deqing Gonggan is an extremely rare natural hybrid of oranges and mandarins. Its shape and color closely resemble oranges, with a well-proportioned form (typically 6.0–6.6 cm in diameter and 5.4–5.9 cm in height), large size (usually 110–150 grams per fruit), and thin skin (generally less than 2.3 mm thick). The rind is golden-yellow, clean, and smooth. **Crisp, Tender Flesh** – In addition to its orange-like beauty, Deqing Gonggan offers the advantages of easy-to-peel rind and juicy, tender flesh typical of loose-skinned citrus. Its flesh is delicate, translucent, crisp, and refreshingly seedless and pulp-free – qualities unmatched by other mandarins or oranges. **Rich, Honey-Like Aroma** – Deqing Gonggan has a distinctive fragrant, sweet flavor, with a soluble solids content generally exceeding 11% (national standard ≥10%), total acidity below 0.3% (national standard 0.9%), and a solids-to-acid ratio as high as 36.7:1 (national standard ≥10:0.9). It is one of today’s rare high-sugar, low-acid premium varieties. **High Nutritional Value** – Deqing Gonggan is highly nutritious, containing abundant organic fructose and sterile water, along with various vitamins, organic acids, trace elements, and minerals. Nutritionally, its organic fructose component effectively replenishes the body’s carbohydrates without spiking blood sugar levels like regular sugars. Its juice, rich in various nutrients, helps hydrate and nourish the body during the dry autumn and winter seasons. **High Edible Rate** – Thanks to its thin skin and minimal seeds (typically only about six per fruit) and seedless, pulp-free flesh, Deqing Gonggan has an edible rate exceeding 80% (national standard >70%). **Brand and Honors of Deqing Gonggan:** (1) November 2004: Awarded national "Protected Geographical Indication" registration certification. (2) October 2003: Deqing County proudly earned the title "Hometown of China’s Gonggan." (3) November 2004: Deqing County was honored as one of "China’s Top Ten Citrus Production Counties." (4) December 2000: Awarded the title "China Famous Fruit." (5) September 2002: Certified as a China Green Food Grade A product. (6) September 2004: Honored as a "Guangdong Famous Product." (7) January 2005: Awarded the title "Guangdong Famous Trademark." (8) December 2002: Designated as the official fruit of the World Guangdong Fellow Association... Thanks to these achievements, Deqing Gonggan has gained widespread fame. Among today’s wide array of fruits, it stands out like a noble beauty – refined, elegant, and peerless. Upholding its once-exclusive royal status, it has become a premium fruit and the finest among citrus. **Essential Growing Conditions for Deqing Gonggan** The superior quality of Deqing Gonggan stems from Deqing County’s unique geography and climate. Located in central-western Guangdong, Deqing lies in a low-latitude region with a mild climate, abundant heat, ample rainfall, and a long frost-free period. The annual average temperature is 22.2°C, annual precipitation averages 1,434 mm, and annual sunshine duration is about 1,662 hours. The county is surrounded by mountains on three sides (east, west, and north), with vast forest coverage, picturesque landscapes, and the Xijiang River – China’s second-largest river – flowing along its southern border. This creates a microclimate with warm winters, cool summers, and significant day-night temperature variations year-round. The mountainous and farmland soils in Deqing are mainly sandy loam. Through long-term human improvement and utilization, the soil has developed into a deep, loose, well-aerated layer with excellent water and nutrient retention, high organic matter content (1.27–1.94% in dry land, over 2% in paddy fields), and a pH range of 4.5–6.5. These exceptional geographical, soil, and climatic conditions are perfectly suited for Gonggan growth, providing sufficient effective accumulated heat and optimal day-night temperature differences. This ensures the fruit’s peel coloring, tissue softening, and optimal levels of soluble solids, organic sugars, vitamins, organic acids, trace elements, and minerals. **Development and Current Status of Deqing Gonggan** Deqing Gonggan is a traditional, premium agricultural product of Deqing County with a long cultivation history. Historical records indicate that Deqing, anciently known as Duanxi or Kangzhou, had well-developed agriculture during the Kaiyuan era of the Tang Dynasty, with farming as the main industry. Large-scale cultivation of Gonggan and sugar oranges was common in areas such as Maxi, Guanxi, and Xinxu towns. After the reform and opening-up, especially in recent years, Deqing County has leveraged technological advantages to improve quality. It has secured technical support from research institutes and universities, establishing virus-free Gonggan nurseries, variety purification and rejuvenation centers, preservation and processing technology promotion centers, standardized production systems, and quality control systems. A 35,000-mu (2,333-hectare) green food production demonstration base for Gonggan has been created, along with the promotion of biological pest control techniques like "mite control using predatory mites." In terms of operations, the county follows an agricultural industrialization model, adopting market-oriented approaches and collaborating with major merchants to establish an integrated production, preservation, processing, and sales system. To build "China’s No.1 Citrus," over 6 million yuan has been invested to develop hundreds of acres of Gonggan parent orchards, standardized virus-free seedling bases, and a Gonggan purification and rejuvenation center. The first national standard for Gonggan production was established, creating one national-level standardized production demonstration zone and 26 provincial/municipal/county-level standardized production and management zones. The "Decision on Strengthening Gonggan and Sugar Orange Production Management to Promote Sustainable Industry Development" was enacted to enhance cultivation and quality control. Several integrated production and distribution fruit companies and numerous large producers and distributors have been supported, along with the establishment of citrus associations. These measures have collectively improved Gonggan quality and market competitiveness. In recent years, following the vision of "China’s No.1 Citrus," promotional events have been held at iconic venues like Beijing’s Great Hall of the People, Diaoyutai State Guesthouse, and in Shanghai, Northeast China, Northwest China, Central China, and elsewhere. Over 130 marketing outlets have been established in more than 50 major cities across the Pearl River Delta, Yangtze River Delta, Beijing-Tianjin region, Northeast China, Sichuan, and Chongqing. Overseas markets in Hong Kong, Macau, the Netherlands, the UK, and Singapore have also been expanded. **Current Production and Market Reach** Currently, Deqing County has over 30,000 growers cultivating Gonggan and sugar oranges on 150,000 mu (10,000 hectares). This year, 70,000 mu (4,667 hectares) are in production, yielding over 100,000 tons. Total sales revenue is expected to reach 400–500 million yuan, with per capita income for farmers exceeding 1,000 yuan from this crop alone. Today, Deqing Gonggan and sugar oranges are popular nationwide and renowned in overseas markets such as Hong Kong, Macau, the Netherlands, the UK, and Singapore. **Expert and Celebrity Reviews on Deqing Gonggan** Deqing Gonggan is hailed as the finest among citrus, earning widespread praise: – *Tiemuer Awat, former Vice Chairman of the Standing Committee of the National People’s Congress*: "I’ve overseen agriculture nationwide and traveled across the country, but I’ve never tasted such delicious fruit. Deqing Gonggan is not only beautiful and tasty but also sweet, refreshing, seedless, juicy, and thirst-quenching. Eating more won’t cause excessive internal heat, and it feels very healthy..." – *Professor Ma Peiqia, Fruit Tree Research Institute, Guangdong Academy of Agricultural Sciences*: "Deqing Gonggan has an attractive shape, golden color, sweet fragrance, thin skin, few seeds, crisp flesh, no residue, high sugar content, low acidity, and an exceptional taste unmatched by other citrus varieties. Its shape, color, juice vesicle shape, and attachment resemble oranges, but its thin albedo layer, easily separable segments, and peel connection reflect mandarin traits. It combines the aesthetic shape, golden hue, rich flavor, and aroma of oranges with the tender, easy-to-peel, seedless, moderately sweet flesh of loose-skinned citrus. It also carries the refreshing sweetness of pomelo, integrating the strengths of sweet oranges, sugar mandarins, and honey pomelos. It’s clear that the 21st century will be the century of hybrid citrus." **Origins and Traits of Deqing Gonggan** Originally a premium, rare citrus variety from Zhaoqing, Guangdong, Deqing Gonggan earned its name due to its exceptional quality, which led to its use as a tribute to the imperial court in the past. Research confirms that Gonggan is a natural hybrid of oranges and mandarins, possessing the strengths of both. Deqing is the primary origin of Gonggan, with a long cultivation history. Through generations of careful breeding and refinement by the people of Deqing, it has been preserved and passed down to this day. **Why Deqing Gonggan Stands Out** Deqing Gonggan features a beautiful shape, golden color, thin skin, few seeds, crisp and tender flesh, sweet honey-like aroma, high sugar content, low acidity, and a rich flavor. It combines the aesthetic appeal of oranges with the tender, easy-to-peel flesh of citrus – qualities unmatched by other citrus varieties. Known as the "King of Citrus," Deqing Gonggan averages 120–150 grams per fruit, with a diameter of 60–65 mm. Its soluble solids content (mainly sugar) exceeds 11–13%, edible rate surpasses 76.7–79%, and solids-to-acid ratio reaches 36.7–37.1:1, with total acidity as low as 0.3–0.35%. It matures around the Winter Solstice, offering a long harvest period and making it an excellent festive fruit. Rich in vitamins, trace elements, minerals, and organic acids, it effectively relieves indigestion and quenches thirst during autumn and winter, replenishing essential nutrients and hydration. Recognized by the fruit industry as a trendy, healthy new star, it’s truly a fruit for the modern age.

Among the vast array of fruits available today, they stand out like a noble imperial concubine—refreshingly elegant and peerless, upholding the noble quality of past palace-exclusive produce, now emerging as a new aristocrat among fruits and the finest of citrus. Essential growing conditions for Deqing Gonggan oranges The reason Deqing Gonggan oranges can surpass others with their superior quality lies in the unique geographical environment and climatic conditions of Deqing County: Located in central-western Guangdong Province, Deqing sits in a low-latitude area with a mild climate, abundant heat, plentiful rainfall, and a long frost-free period. The annual average temperature is 22.2°C, annual average rainfall is 1,434 mm, and annual average sunshine duration is 1,662 hours. The county is surrounded by mountains on its eastern, western, and northern sides, featuring vast forest coverage and beautiful landscapes, while to the south lies the Xijiang River, the second-largest river in China by flow volume. This combination creates a microclimate with warm winters, cool summers, and large day-night temperature variations year-round. The mountainous and arable soils in Deqing are mainly sandy loam. Through long-term human improvement and utilization, the soil has developed into deep, loose, and well-aerated layers with good water and nutrient retention, rich in organic matter (1.27–1.94% in dry land, over 2% in paddy fields), and a pH value between 4.5 and 6.5. These exceptional geographical, soil, and climatic conditions are highly suitable for the growth of Gonggan oranges. They not only meet the effective accumulated temperature required for growth but also achieve the ideal day-night temperature variation, enabling the fruit’s peel coloration, flesh softening, soluble solids, organic sugar, vitamins, organic acids, trace elements, and mineral contents to all reach optimal standards.
