The glass greenhouse not only has beautiful appearance, but also has strong sealing, which can isolate the interference of external environment. All kinds of fruits and vegetables are planted across seasons throughout the year. Moreover, the service life of the glass greenhouse is more than 20 years, the maintenance is simple, and the later operation cost is greatly reduced. Glass greenhouse is the main type of greenhouse built in China at present, with complete specifications and types, such as multi span glass greenhouse, Wenluo glass greenhouse, single span glass greenhouse, semi closed glass greenhouse, distributed photovoltaic glass greenhouse and other purposes and functions. In addition to technology, the glass used in greenhouse construction is also the top priority. A good glass can not only improve the light transmittance, but also reduce the greenhouse maintenance cost; At present, the glass standard on the top of the greenhouse is diffuse reflection glass, and the side wall standard is ordinary double-layer insulating glass;

How diffuse reflective glass plays a role in increasing greenhouse production, there are three key points;

First point: high light transmittance

Diffuse reflective glass has a high transmittance of 97.5%, which is 7.5% higher than the 90% transmittance of ultra white glass used in ordinary greenhouse. After comparison, the total yield per mu increased by 15% to 20%;

The 97.5% light transmittance of diffuse reflective glass makes the plants inside the greenhouse closer to the conditions of outdoor growth, so that the greenhouse shields only the impact of external natural disasters and insect pests, rather than the favorable condition of light; In addition, the effect of haze on greenhouse production can not be ignored.

Second point: haze

At the beginning of research and development, in order to adapt to different climates in different regions of the world, diffuse reflective glass specially developed 8 haze specifications. In China, Gansu and Guangdong are two representatives. The light in Gansu is weak, the weather is cold, and the weather in Guangdong is hot and the light is sufficient.

High haze scattering glass is used in high-temperature areas to prevent excessive light from affecting vegetable growth. Low haze glass is used in areas with weak light to maximize the light transmittance of greenhouse.

Scattered glass haze can effectively inhibit the respiration of vegetables and ensure that vegetables are growing all day. In contrast, compared with ordinary glass greenhouse, it can shorten the growth cycle of 7 days, and one more crop of fruits and vegetables can be harvested every year for circular planting greenhouse;

Third point: light selection performance

Diffuse reflective glass is different from ordinary ultra white glass. The light of ordinary ultra white glass is ultraviolet, which passes through 90% of all light flux, while greenhouse diffuse reflective glass increases the blue, purple and infrared light required for plant growth, weakens the light of other bands, and retains the light required for plant growth to a greater extent;

Greenhouse diffuse reflective glass now has a great influence in China. The emergence of scattering glass also means that greenhouse profiles have entered a slow replacement process. Ordinary glass can no longer meet the planting needs of greenhouse. Only more scientific and targeted profiles can ensure the increase in production and income of greenhouse;
