Semi-dismounting-type greenhouse back wall

Abstract

The invention discloses a semi-dismounting-type greenhouse back wall structure comprising a lower half section composite wall body and an upper half section composite wall body. The lower half section composite wall body comprises a heat radiation layer, a heat-accumulating layer and a heat-insulation layer from the inside out; the dismounting-type wall body comprises a back wall column supporting structure, a detachable inner layer jute fiber board and a detachable outer layer jute fiber board which are respectively installed at the inner side and outer side of the back wall column supporting structure; the jute fiber board can be freely installed and dismounted; the installation of the jute fiber board can reduce the indoor heat dissipation to the outside in winter and has the function of heat insulation; the jute fiber board can be dismounted in summer for increasing ventilation area of the greenhouse and therefore the indoor temperature can be effectively reduced. The semi-dismounting-type greenhouse back wall of the invention can be used in Jiangsu areas for overwintering production and over summer production, thereby solving the problem that year-round production cannot be carried out in greenhouses in the south and increasing the soil utilization rate; meanwhile, the cost for the greenhouse back wall structure is low; the construction is convenient and economic benefit is increased.

Description

technical field [0001] The invention relates to a wall body of a solar greenhouse, in particular to a semi-detachable rear wall of a greenhouse. Background technique [0002] The solar greenhouse is a unique horticultural facility in my country. In winter in cold regions, off-season vegetable cultivation can be carried out even without heating. This mainly depends on the thermal insulation structure of the solar greenhouse. The thermal insulation structure of the solar greenhouse is mainly The rear wall and the rear slope, the rear wall and the rear slope increase the indoor temperature by using some thermal insulation materials. The development of solar greenhouses is relatively mature, especially in northern my country. In recent years, Jiangsu has also begun to develop and use solar greenhouses on a large scale, but most of the structures of solar greenhouses have not been optimized or designed according to local climate conditions. At present, the back walls of solar gre...

Problems solved by technology

The development of solar greenhouses is relatively mature, especially in northern my country. In recent years, Jiangsu has also begun to develop and use solar greenhouses on a large scale, but most of the structures of solar greenhouses have not been optimized or designed according to the local climate conditions.

At present, the back walls of solar greenhouses in my country are mostly fixed masonry structures, especially in the summer of Jiangsu. The heat storage and heat insulation performance of the walls causes the indoor temperature to be too high, resulting in a high idle rate of the greenhouses, which prevents annual production and wastes Land Resources
