Performance and Advantages of New Solar Greenhouse

The overall structure of the new solar greenhouse is consistent with the traditional solar greenhouse, and the span can reach more than 15 meters. After the wall part is built with soil wall, it is reinforced with cement mortar, which reduces the risk of collapse and increases the durability and service life. The film on the shed surface is fixed by circlip slot, which is convenient to replace the film in the future. This structure of the greenhouse span, large space, can be equipped with mobile seedbed, mobile sprinkler irrigation and other advanced equipment, suitable for scientific research, breeding, exhibition and other high value-added industries.

In terms of heat preservation measures, the new solar greenhouse adopts materials such as covering heat preservation quilt and shed film to ensure the temperature in the greenhouse. Especially in the cold season, the indoor temperature can be increased by 2~3 ℃ during the day and 3~4 ℃ at night by covering the thermal insulation quilt or grass thatch. The greenhouse film has the advantages of good light transmission, high strength, and strong anti-condensation, which helps to increase the indoor temperature and maintain appropriate humidity.

In terms of functional characteristics, the new solar greenhouse is characterized by good thermal insulation performance. Without heating, it can maintain a temperature difference of 15-20 degrees Celsius between indoor and outdoor, and some well-designed greenhouses can even reach higher temperatures. In addition, the lighting is good, the light transmittance is more than 70%, and the energy saving is realized.

In terms of construction requirements, the new solar greenhouse should choose plots with fertile soil, deep soil layer and high organic matter content for construction, and consider places with convenient drainage and water supply and convenient transportation. The construction is extended from east to west to facilitate the maximum use of solar energy.
