The internal shading system is a shading facility installed inside the greenhouse. It is used to adjust the light intensity, temperature and humidity and other environmental factors in the greenhouse. By adjusting the coverage and opening degree of the shading net, the transmittance of sunlight is controlled to reduce the light intensity in the greenhouse and reduce the temperature in the greenhouse, especially at noon and afternoon. The soil temperature can drop to the range of 18℃-22℃, which is very suitable for crop growth.
The system is usually composed of shading nets, shading boards, motors, transmission parts, etc. It uses technologies such as automatic control, data acquisition, and the Internet of Things to shade, cool, moisturize, and block rain, creating a better growth environment, helping farmers to ensure crop quality and yield, simplify management, and improve production efficiency.
The role of the internal shading system: ① Grasp the environmental factors
Control the light intensity entering the greenhouse or shed, thereby adjusting the photosynthesis and growth rate of crops, keeping the heat of the shed within a suitable range, and on rainy days, the evaporation in the greenhouse will be weakened, the surface will be relatively moist, and the water content in the soil will increase to maintain the environmental humidity.
