As we all know, high-quality glass greenhouses can produce higher productivity within a limited greenhouse area. The improvement of production capacity depends on various factors. The reason for the high yield of smart glass greenhouses is on the one hand due to the improvement of planting technology, which can individually configure different nutrient solutions for plants at each stage of the greenhouse. Plants grow well if they are well fed. However, the increase in yield brought by planting technology is only one aspect. The other aspect is the control of greenhouse environment.

The internal environment control system is an important component of the greenhouse, including wet curtains, fans, skylights, internal and external shading, temperature monitoring and many other aspects. In addition, the greenhouse standard diffused glass is also an important component of the internal temperature control of the greenhouse. Equipment profiles.

How does greenhouse standard diffused glass control the temperature inside the greenhouse?

Greenhouse standard diffused glass does not control the temperature inside the greenhouse, but adjusts the temperature of the light hitting the surface of the plant leaves. By reducing the temperature on the surface of plant leaves, the greenhouse can achieve the effect of controlling the internal temperature.

Diffuse glass is the main medium through which light passes inside the greenhouse. When the sunlight enters the greenhouse through the diffuse glass, it has been processed by the glass (diffuse glass), and the light intensity at this time has been reduced.

One of the reasons is the scattering characteristics of greenhouse scattering glass. When light passes through the glass, the scattering glass will scatter the incident light into multiple beams of light without changing the luminous flux. Thereby weakening the intensity of light and preventing the impact of light on plant photosynthesis.

For example: Scattering glass is like a shower head, and incident sunlight is like a water pipe in the shower head. When the water delivery volume of the water pipe remains unchanged (the light flux remains unchanged), the water (light) that comes out is no longer One strand (one beam), but scattered into multiple beams of water (multiple beams of light). Then the impact of water (light intensity) will be reduced a lot. The intensity of light reaching the surface of the plant leaves will also be reduced.

Another temperature control factor is the haze value characteristics of the diffuse scattering glass itself (overseas benchmark value Hortiscatte). The haze value is different from scattering. The haze value reduces the overall light intensity and blocks excessive light.

The total amount of light suitable for the growth of greenhouse plants is retained into the interior of the greenhouse. The haze specifications of greenhouse standard diffused glass vary according to longitude and latitude, and there are many customized types. There are 9 specifications: 0, 10, 20, 30, 40, 50, 70, 75, and 80. The areas suitable for planting in China are divided into 9 major areas. Each area is based on 3-5 years of meteorological data, light intensity, and then Choose scattering glass with different haze specifications.

As usual, let’s give an example: For example, when a smart glass greenhouse was built in the Miyun area of Beijing, local meteorological data, precipitation, light intensity, severe weather intensity and other data for the past 50 years were collected. When everything was ready, the construction of Beijing's first large-scale fruit and vegetable production base began.

The haze value of diffuse scattering glass is like applying a hydrogel film to the mobile phone screen. While ensuring the light, it also reduces the light intensity, making it less dazzling and the light is not so intense.

The light transmittance of our Yuhua greenhouse glass is as high as 98%, and there are up to 8 haze options to fully protect the world's glass greenhouses.
