Cold Winter Overwintering Greenhouse

The Cold Winter Overwintering Greenhouse is a professional passive thermal preservation planting facility specially engineered for extreme cold climate areas. Designed to resist freezing temperatures, heavy snow and strong winter winds, this greenhouse enables continuous vegetable, flower, seedling and berry production throughout severe winters. Unlike ordinary multi-span greenhouses that rely on large amounts of heating energy during cold seasons, the overwintering greenhouse absorbs solar heat during the day and preserves heat efficiently at night, achieving zero or low-energy winter planting. It has become the most reliable and cost-effective

The greenhouse adopts a reinforced hot-dip galvanized steel arch frame with full anti-corrosion and rust-proof treatment. The upgraded thickened steel structure greatly improves wind resistance and snow load capacity, ensuring stable operation under harsh winter weather. The overall service life of the steel skeleton exceeds 15 years, adapting to long-term frost, snow erosion and outdoor exposure. The reasonable wide-span and column-free interior design provides a large barrier-free working space, allowing mechanical farming, automated irrigation systems and three-dimensional planting racks to operate freely, significantly improving land utilization and planting efficiency.

Equipped with high-transparent, anti-fog, anti-drip and UV-resistant agricultural film, the greenhouse maximizes solar light intake on short winter days. The high-performance film delivers uniform scattered light inside the greenhouse, preventing crop sunscald and reducing condensed water accumulation. By lowering humidity fluctuation and inhibiting bacterial and fungal growth, the covering material effectively reduces crop diseases and improves the quality and yield of overwintering crops such as strawberries, tomatoes, cucumbers and leafy vegetables.

The core feature of the Cold Winter Overwintering Greenhouse is its super strong heat storage and thermal insulation system. It adopts a multi-layer composite insulated north wall with heat absorption and heat preservation functions. The wall fully collects solar thermal energy during sunny daytime and releases heat steadily after dark. Matched with an automatic rolling waterproof thermal insulation quilt, the greenhouse forms a fully enclosed heat-preservation system that greatly reduces nighttime heat dissipation. Even when the outdoor temperature drops to -20°C or lower in severe winter, the indoor growing temperature can be stably maintained above 5°C, ensuring normal crop growth and completely avoiding frost damage. This passive solar heating technology saves over 90% of winter heating costs compared with traditional greenhouses.

To achieve full-year balanced planting, the greenhouse can be equipped with complete modular supporting systems. Electric rolling ventilation and top skylights adjust indoor humidity and air circulation. Exhaust fan and cooling pad systems provide rapid cooling in summer, while external sunshade nets prevent overheating. Automatic drip irrigation and water-fertilizer integration equipment realize precise and efficient crop nourishment. Optional intelligent temperature, humidity and light sensors, together with PLC automatic control cabinets, can monitor and adjust the internal environment in real time, realizing intelligent and unmanned planting management.

With outstanding cold resistance, ultra-low operating cost and stable performance, the Cold Winter Overwintering Greenhouse is widely used for overwintering vegetable planting, high-value berry cultivation, flower overwintering and seedling breeding in cold regions. It solves the seasonal planting limitation of cold climates, extends the growing cycle and creates considerable economic benefits for farmers and agricultural bases. All sizes and supporting systems can be fully customized according to local minimum temperature, snow load and planting needs, providing professional and reliable cold-resistant agricultural solutions for global users.
