Product Name: Gushan No.2 Longan (Dimocarpus longan cv. Gushan No.2)

Description:
Gushan No.2 Longan is a premium early-maturing longan variety originating from Beiyang Village, Yunlu Town, Jiedong County, Guangdong Province, China. Named after the “Gushan” area where the original mother tree was discovered, this variety was developed through 17 years of systematic selection and breeding by agricultural science and technology departments in collaboration with provincial and municipal research institutions. It received the First Place Award at the Guangdong Province Rare and Excellent Fruit Evaluation in 1986, the Gold Award at the Second China Agricultural Exposition in 1995, and was officially certified by the Guangdong Crop Variety Approval Committee in 2000 (Approval No.: Yue Shen Guo 2000001). It has since been promoted across 210,000 mu in Guangdong Province, including 140,000 mu in Jieyang City alone, making it one of the most representative early-season fresh-eating longan varieties in eastern Guangdong.

A Longan That Owns the Early Season:

The defining feature of Gushan No.2 is its exceptional earliness. It ripens in mid-to-late July in the eastern Guangdong production region, approximately 7–10 days earlier than the renowned Shixia longan. This early-season advantage allows growers to capture premium market pricing during the summer longan season when supply is limited. The variety has been described as a "quality fresh-eating early-maturing variety" with strong adaptability and stable productivity.

Appearance:
The fruit is near-flat-round with slightly raised shoulders, uniform in size and neatly shaped. The skin is reddish-brown to pale grayish-brown, notably thin, with visible turtle-shell cracking and wart-like protrusions. Inside, the flesh is waxy yellow, milky-white and semi-transparent, with a crisp, refreshing texture and a clean, sweet flavor accompanied by a distinctive fragrance. The flesh is "dry-pack" (no dripping juice) – juice does not drip when the fruit is opened – and separates easily from the seed. Average fruit weight is 10–12 grams, with a 66%–70.8% edible rate and a soluble solids content of 18.89%–20.5%. The seed is small, round, and brown. Vitamin C content reaches 85.7 mg per 100mL of juice.

Key Commercial Advantages:

• Early Season Market Window – Ripens in mid-to-late July, about 7–10 days ahead of Shixia, capturing premium early-season demand

• Gold Award Winner – First Place at the 1986 Guangdong Rare Fruit Evaluation and Gold Award at the 1995 China Agricultural Exposition

• High Sugar & Distinctive Flavor – 18.89%–20.5% Brix with a crisp, sweet taste and unique aroma

• Thin Skin, Thick Flesh, High Edible Rate – 66%–70.8% edible rate with a small seed

• Dry-Pack (不流汁) – Juice does not drip, making it ideal for fresh market sales and transport

• Early Bearing & High Yield – Flowers easily and bears fruit early; top-grafted trees fruit in the second year. Mature orchards achieve 100 kg per mu by year 2, with yields increasing annually

• Mature Dwarfing Technology – Established dwarfing, early-bearing, high-yield cultivation system enables rapid returns and manageable orchard management

Growing Regions:
Native to Beiyang Village, Yunlu Town, Jiedong County, Guangdong Province, Gushan No.2 Longan is primarily cultivated in Jiedong (Guiling, Yuhu, Baita, Yunlu, Longwei Towns), with over 100,000 mu in Jiedong alone and 140,000 mu across Jieyang City. It has also been successfully introduced to Jinjiang, Fujian, and other longan-growing regions in southern China. The region's subtropical monsoon climate, with abundant sunshine (1,700–2,000 hours annually), annual average temperature of 20–22°C, and well-drained soils, provides ideal conditions for premium longan production.

Cultivation Notes:

• Climate: Full sunlight with 1,700–2,000 hours annual sunshine; annual average temperature of 20–22°C; winter minimum above -3°C; reliable water source and good drainage

• Soil: Deep, slightly acidic, loose, moist, non-waterlogged sandy loam or loam on hillsides, upland fields, or dryland

• Planting Density: 30 trees per mu on hillsides; 35 trees per mu on flatland; 1m × 1m × 1m planting holes

• Dwarfing System: Train to a semi-round canopy with trunk height below 50 cm; canopy spread reaches 2m and tree height 1.5–2m within two years

• Fertilization: 4 applications per year with N:P:K ratio of 1:0.3:1.5; emphasis on potassium for fruit quality

• Fruit Management: Flowers abundantly but sets fruit sparsely; focus on flower and fruit retention and balanced crop load

• Pest Management: Monitor for litchi stink bug, fruit borer, and downy blight; apply trichlorfon and Ridomil MZ as needed

• Grafting Note: Graft union compatibility is relatively poor; select appropriate rootstock combinations for successful grafting

• Harvest Timing: Harvest promptly at optimal maturity as the variety loses sugar rapidly (回糖快) and has a short picking window

Harvest Season:
Mid-to-late July – a premium early-season longan that delivers gold-award quality, distinctive sweet flavor, and a strategic early-market window. With its thin skin, thick flesh, high edible rate, and dry-pack nature, Gushan No.2 is an excellent choice for fresh market sales, premium gift packaging, and early-season e-commerce logistics in southern China's longan production regions.
