Solar greenhouse with high land utilization rate

Abstract

The invention discloses a solar greenhouse with a high land utilization rate. The solar greenhouse comprises a rear wall, a gable wall, stand columns, a front slope, a heat storage ditch, a top operation platform and a waterproof platform. The rear wall comprises a supporting framework, a polyphenyl foam board and a light reflecting curtain, the polyphenyl foam board is fixedly arranged on the supporting framework, and the light reflecting curtain is fixedly arranged on the inner side of the polyphenyl foam board. The waterproof platform is arranged on the outer side of the rear wall, the height of the waterproof platform is 30cm, the width of the waterproof platform is 30cm, the length of the waterproof platform is equal to that of the outer side of the rear wall, the stand columns comprise a rear stand column and a front stand column, the light reflecting curtain and the polyphenyl foam board are arranged between the rear stand column and the front stand column, and the height of the rear stand column and the height of the front stand column are identical to that of the highest point of the front slope. The heat storage ditch is arranged between the rear wall and the front stand column, the width of the heat storage ditch is 1.2-1.5m, the depth of the heat storage ditch is 0.5-1m, the length of the heat storage ditch is equal to that of the inner side of the rear wall, and carbonized rice hulls are filled in the heat storage ditch. The land utilization rate is improved, a cultivation bed is not dug downwards, building is not influenced by the underground water level, and the solar greenhouse can be popularized across the country.

Description

technical field [0001] The invention relates to a solar greenhouse, in particular to a solar greenhouse with high land utilization rate, belonging to the technical field of vegetable cultivation. Background technique [0002] Ordinary energy-saving solar greenhouses are agricultural and horticultural facilities formed on the basis of scientific use of solar energy. They have the characteristics of high utilization rate of light energy, fast heating and strong heat preservation. Even without artificial heating in deep winter, it can produce a variety of heat-loving vegetables such as cucumbers, tomatoes, eggplants, and spicy (sweet) peppers. [0003] At present, the walls of ordinary energy-saving solar greenhouses with better thermal insulation are rammed earth structures. The walls are constructed by excavators and bulldozers. The thickness of the walls is generally 4-5.5m. The land utilization rate is low. At the same time, the wall is a solar greenhouse with a rammed ea...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a solar greenhouse with high land utilization rate in view of the above deficiencies, which overcomes the defects in the prior art that the land utilization rate is low and is not suitable for construction in areas with shallow groundwater levels. The solar greenhouse has the advantages of high land utilization rate, the construction is not affected by the groundwater level, and the heat storage and heat preservation performance is equivalent to the solar greenhouse with rammed earth structure walls.
