In an era where food safety and sustainability are paramount, Zhuhai’s “Haojihui” organic vegetable farm has set a new benchmark. By leveraging advanced soilless cultivation techniques, this farm has achieved China’s organic certification and the prestigious USDA 100% Organic Certification—making it the only soilless farm in China to earn such recognition.
How It Works: Zero Pesticides, Zero Synthetic Fertilizers
The farm, led by Macau entrepreneur Sun Zhenhong, uses a hydroponic floating raft system. Vegetables grow in 20 cm-deep water channels, with roots submerged in nutrient-rich, fermented bio-solutions derived from organic matter. This eliminates the need for chemical fertilizers while ensuring optimal plant nutrition.
To combat pests without pesticides, the farm employs a six-layer defense system:
-
Protective netting to block insects
-
Pheromone traps to lure and capture pests
-
UV light traps for nocturnal insects
-
Sticky traps for flying pests
-
Beneficial microbial sprays to repel harmful insects
-
Manual inspections to remove infested plants
This zero-chemical approach ensures no toxic residues, meeting the strictest organic standards in both China and the US.
From Farm to Table in 24 Hours – Supplying Hong Kong & Macau
The farm’s highly efficient post-harvest process ensures freshness:
-
Vegetables are harvested via water channels to minimize handling.
-
They are trimmed, packed, and stored at 3–8°C within hours.
-
Deliveries reach Macau and Hong Kong within 24 hours, supplying high-end resorts like The Venetian, Galaxy, and Wynn Palace.
Currently, the farm produces 6 tons of vegetables monthly, including romaine lettuce, kale, and butterhead lettuce, with plans to expand into mainland China after final certification in August 2024.
The Future: Expansion & Agri-Education
With 50 acres of land (only 10 acres currently developed), Sun Zhenhong plans to:
-
Launch Phase 2 in late 2024, integrating eco-tourism and agricultural education.
-
Host free student workshops to promote modern farming techniques across the Greater Bay Area.
A Model for Sustainable Agriculture
The success of Haojihui Organic Farm proves that soilless, chemical-free farming can meet the highest global organic standards. As demand for safe, sustainable produce grows, this model offers a blueprint for future farms—combining innovation, environmental stewardship, and profitability.
