1. Convenient management, conducive to mechanization　

The greenhouse adopts a high ridge, large span, and round arch design. The planting surface has no supporting members such as columns or ties. The bottom corners and roof of the greenhouse are reserved for ventilation belts to facilitate temperature and humidity control. Convenient for small mechanical operations. The large space design is suitable for the facilitated cultivation of vegetables, fruit trees, grapes and other fruits and vegetables, and is conducive to the adjustment of the planting structure.

2. Low construction cost and high land utilization rate　

Greenhouses can be produced using organic soilless cultivation techniques, and they can also be produced using soil cultivation methods. Compared with the solar greenhouse, the construction links such as the back wall, roof insulation layer, and land reclamation have been eliminated, and the area of the back wall and the greenhouse shading belt has been reduced, saving about 55% of investment per mu. Land use The rate increased by about 50%.

3. Good output efficiency, suitable for large-scale planting 　sunshine board greenhouse

The Hexi Corridor is cold in winter, with extreme low temperatures as high as -28 ℃, and the low temperature in winter in normal years is around -23 ℃. According to observations, the time when the night temperature ≤ 5℃ in the outer thermal insulation double-row steel frame greenhouse appeared in late December, and the time when the night temperature ≥ 5℃ appeared again at the end of January of the following year. There were about 40 days before and after the room temperature was lower than 5 ℃, this stage cannot be used for fruit and vegetable production, but during this period, the factory seedlings in the solar greenhouse can be used to make up for the shortcomings in production.

4. Stable, strong resistance to adversity　

The frame material of the greenhouse is mainly steel pipe and concrete, which improves the wind resistance, snow resistance and compression resistance of the greenhouse. At the same time, the indoor heat storage space is large and the buffering performance is strong, which can improve the cold-proof and thermal insulation ability of the greenhouse, effectively reduce the harm of continuous rainy and snowy weather in winter, and further improve the practicability and performance of the greenhouse.

5. It is easy to promote and facilitate the integrated assembly of new technologies and new products.

The optimized shed design and open farming space are conducive to the integration and assembly of organic and ecological soilless cultivation, soil testing formula, water and fertilizer integration, automatic rolling curtain system, automatic ventilation, Internet of Things and other practical new technologies and new products. Improve the automation management and standardized production level of greenhouses.
