During the hot summer season, the temperature inside vegetable greenhouses often skyrockets, becoming a major problem that troubles many growers. In response to this pain point, Hubei Jinlong New Materials Co., Ltd. has launched a series of products with built-in reflective functionVegetable greenhouse specific tarpaulinEffectively solve the problem of greenhouse overheating through technological innovation and create a suitable environment for vegetable growth.

Reflective layer design: the "black technology" for cooling in summer

Hubei Jinlong's vegetable greenhouse tarpaulin fully considers the summer cooling demand in product design and has launched a summer specific tarpaulin. This type of tarpaulin has a light transmittance controlled at ≤ 50% and is equipped with an aluminum foil reflective layer, which can effectively reflect over 90% of solar radiation.

The cooling effect of this design is very significant. According to actual test data from Shouguang, Shandong, during the high temperature season in summer, the temperature inside the Golden Dragon greenhouse with reflective curtains is 9 ℃ lower than the outdoor environment, and the tomato cracking rate decreases from 15% to 3%. This means that growers no longer need to worry about crops being burned by high temperatures, which can significantly reduce economic losses caused by high temperatures.

Intelligent thermal management: not just simple reflection

In addition to the basic reflective layer design, Hubei Jinlong has also developed more advanced "photothermal management" coating technology. This technology not only effectively blocks the disorderly loss of infrared heat (achieving winter insulation function), but also reflects excess solar heat energy in summer, achieving intelligent cooling effect, just like installing "smart air conditioning" in greenhouses, helping growers stabilize the temperature inside the greenhouse in the most suitable range for crops.

The art of balancing transparency and cooling

Hubei Jinlong's technicians are well aware that vegetable growth cannot be separated from light, and simple shading and cooling may affect the efficiency of photosynthesis. Therefore, the company pays attention to the balance between transparency and cooling in product design.

In response to summer demand, Jinlong tarpaulin adopts a unique "scattered sunlight" technology. The surface of the tarpaulin is treated with special microspheres, which can convert direct sunlight into diffuse light that crops love more. This means that the light can be evenly distributed to every corner of the greenhouse, shining on the middle and lower parts of the plants, reducing shadows, promoting uniform crop growth, and avoiding leaves from being burned by high temperatures in the focal point.

Double layer structure: upgraded cooling effect

For planting scenarios that require higher temperature control, Hubei Jinlong also provides a double-layer structure tarpaulin solution. This design adopts a combination of high transparency on the outer layer (70% -80%) and low transparency on the inner layer (50% -60%), forming a heat barrier through the air layer between the two layers. During the high temperature season in summer, this structure can lower the temperature inside the greenhouse by 3-5 ℃, while reducing the risk of burns to crops from strong light.

Auxiliary measure: Clever application of reflective screen

In addition to the reflective design of the tarpaulin itself, Hubei Jinlong also provides matching reflective screen solutions. This reflective screen is made of polyester aluminum plated film material, with a reflectivity of over 90%. Hanging on the north side or back wall of the greenhouse during installation, perpendicular to the ground, can increase the ground illumination intensity by 25% -40% and raise the greenhouse temperature by 2-3 ℃. In seasons with insufficient light (such as winter), this design can significantly improve the lighting conditions of the lower leaves of crops; In summer, by optimizing the distribution of light and combining it with the cooling function of the tarpaulin itself, better growth environment regulation can be achieved.

Practical application: Visible effect

Hubei Jinlong's reflective cooling tarpaulin has been applied in multiple agricultural bases with significant results:

At the Jiangxi Natural Star Agricultural Base, the use of Jinlong high transparency PVC fabric (with a light transmittance of 82%) combined with reflective screens and electric sunshades increased tomato yield by 15% in winter and reduced cucumber bitterness rate by 30% in summer.

At the hydroponic vegetable base in Jinlong Town, Longzhou County, double-layer PE fabric (with an outer layer transmittance of 75% and an inner layer transmittance of 60%) combined with an intelligent temperature control system is used to achieve year-round production, shortening the lettuce growth cycle to 25 days.

Industry recognition: technical strength of standard setters

As a company involved in drafting the national standard for "Coated Fabrics for Agricultural Greenhouses", Hubei Jinlong's products have passed ISO 9001 quality management system certification and EU CE safety certification. Its tarpaulin products are exported to 30 countries and have a market share of over 40% in the global high-end agricultural facility market.

For growers who are troubled by high temperatures in summer, choosing a special tarpaulin with a built-in reflective layer is no longer just a material purchase, but a key investment in the overall planting efficiency. Hubei Jinlong has proven through technological innovation that a good tarpaulin can indeed keep vegetable greenhouses cool in hot summer days.
