Advantages of solar agricultural greenhouses:
Energy saving, low operating costs.
The front slope Angle of the solar greenhouse is generally set according to the local winter sunlight irradiation Angle, as far as possible to maintain a greater degree of vertical with the light, the use of the back wall, soil or other thermal storage materials to fully absorb solar energy, slowly release heat at night, the entire production process without heating or less heating.
Fast warming, good insulation effect.
The wall, back roof and front slope of the solar greenhouse are all made of good thermal insulation materials, such as polystyrene board or sandwich polystyrene board, perlite and other thermal insulation materials, and straw curtains and thermal insulation covers are used on the front slope. In North China, there is no need to warm the winter production, and the general cold area can also achieve anti-season fruit and vegetable production by adding heating facilities or temporary warming.
Good light transmission performance, high light utilization rate.
Easy to operate and ventilation moisture, easy to manage. The column-free structure facilitates the mechanization operation of small agricultural machinery, reduces labor intensity and saves labor force.
Strong structure, long service life, wind pressure resistance, snow load ability.
Construction can be adapted to local conditions, local materials, reduce costs.
Combined with soilless cultivation and water-fertilizer integration technology, non-cultivated land such as saline-alkali land and desert can be used to save cultivated land resources.
