Description

Technical Field

[0001] The utility model relates to the technical field of agricultural facilities, and more specifically to a desert heat preservation type solar greenhouse. Background Art

[0002] Solar greenhouse is the abbreviation of energy-saving solar greenhouse, also known as warm shed, which consists of gables on both sides, a protective back wall, a supporting frame and covering materials. A solar greenhouse is a greenhouse that is not heated indoors. It absorbs solar energy through the back wall to store and release heat, maintaining a certain temperature level indoors to meet the needs of vegetable crop growth. Some farmers also add heating measures in the greenhouse, such as stoves, boilers, heating pipes, or night insulation measures, such as rolling curtains and quilts.

[0003] Compared with ordinary cultivated land, the desert covers a large area, but the utilization rate is low because the sandy soil in the desert is not conducive to the cultivation of vegetable crops. In order to fully develop and utilize desert resources, save cultivated land, and alleviate the contradiction between the large population and small land resources in desert areas, people have been exploring a new model that combines the development of facility agriculture with ecological windbreak and sand control in arid desert areas to promote the development of facility agriculture to a higher level. Among them, the benefits of solar greenhouses have achieved obvious economic results. Desert solar greenhouses refer to a variety of cultivation modes such as soilless cultivation and water-saving and fertilizer conservation in high-standard seedling solar greenhouses in the desert. However, there are still some problems in the existing technology of building greenhouses in the desert, such as: 1. The wind and sand in the desert are strong, and the weather is cold in winter. It is difficult to ensure the planting temperature in ordinary greenhouses; 2. The transportation of concrete or other wall building materials in the desert is difficult and costly.
