The greenhouse provides a suitable growth environment for internally grown crops, such as light, temperature, humidity, CO 2 concentration, and water nutrition. The overall performance of the greenhouse depends not only on the main structure and covering materials, but also on the reasonable configuration of different greenhouse supporting facilities, such as ventilation systems, shading insulation systems, fan and wet curtain cooling systems, heating systems, irrigation and fertilization systems, supplementary lighting systems Intelligent control system, etc.

Covering material:

The covering materials for the supporting facilities of the greenhouse mainly use glass, polycarbonate plates, plastic films, etc. as the covering materials, and are equipped with special aluminum alloy profiles and rubber seals to ensure that the greenhouse has good transparency and sealing.

Steel structure:

The structure of the supporting facilities of the greenhouse is made of excellent thin-walled steel. After being processed by the factory, it is hot-dip galvanized or other surface anti-corrosion treatment. The specifications of the greenhouse can be designed and manufactured according to user requirements.

Shading insulation system:

The greenhouse shading system is divided into an external shading system and an internal shading system. A special mechanism and a shading screen are used to adjust the light in the greenhouse to ensure that the indoor light and temperature are suitable for the needs of crop growth.

External shading system

The use of an external sun screen with a high shading rate can effectively reduce the indoor light intensity and the indoor temperature from 4 ℃ to 6 ℃. It also has the effect of preventing rainstorm and hail.

Internal shading system

The use of an internal sun screen with a high shading rate effectively reduces the indoor light intensity and the indoor temperature from 3 ℃ to 5 ℃; it can also play a role in thermal insulation in winter.

Insulation system

Install the greenhouse thermal insulation curtain between the greenhouse crops and the inner shade. The heat preservation curtain is gathered in the sunny day, and it forms a space closed system with the lower space of the greenhouse after the night is unfolded, which can effectively reduce the heating space of the greenhouse and reduce the heat loss of the greenhouse.
