Semi-closed greenhouse project in Zhejiang explores climate-controlled cherry tomato production

Zha Xudong, who leads the project on behalf of the owner, confirmed that formal planning and design commenced in early 2024. Zu Guocheng, General Manager of Beijing Oriental Technologies Ltd., the designer & manufacturer of the project, this project combines semi-closed greenhouse design, automated climate management, supplementary lighting, soilless cultivation and integrated resource systems within a single facility.
Zu Guocheng, the system is designed to maintain summer temperatures between 26–30°C while keeping relative humidity below 75%. Higher airtightness and insulation can reduce heating demand and improve carbon dioxide retention, while precision irrigation and fertigation may lower water consumption.
Increasing use of sensors, integrated control platforms and digital management systems is shifting greenhouse production toward data-based operational models incorporating Internet of Things applications, automated decision-making and environmental monitoring.

Why this matters: For operators, this is a water-management story. The useful signal is that direct substrate measurements can help cut drain loss materially without giving up yield or fruit quality, which is exactly the kind of controllable efficiency gain a facility can build on.
Frequently Asked Questions
Why does substrate sensing matter in free-drain strawberry systems?
Because drain percentage tells a grower what already happened, while substrate moisture and EC data show root-zone conditions directly. That makes it easier to cut water loss without guessing.
What is the operator takeaway from this trial?
If the thresholds are understood well enough, growers can reduce drain water materially while protecting yield and fruit quality, which makes sensing an operational tool instead of a reporting tool.
