Greenhouse without need for heating facility

Abstract

The invention provides a greenhouse without the need for a heating facility. The greenhouse comprises a wall body built on a foundation, a support arranged above the wall body and a transparent film laid on the support. The height of the shady side wall body is higher than that of the sunny side. The wall body is formed by a concrete base and thermal insulation layers, wherein the thermal insulation layers are arranged on the concrete base, and at least one side of each thermal insulation layer is formed by connecting expandable polystyrene (EPS) modules. The inner side of the shady side wall body is provided with a circulating water tank. A concrete base of the circulating water tank and the concrete base of the shady side wall body are connected together. The inner side and the outer side of the concrete base of the circulating water tank and the bottom of the circulating water tank are provided with insulation layers formed by connecting the EPS modules. The upper portion of the circulating water tank is provided with a circulating water pump, an outlet of the circulating water pump is connected with a spray nozzle and a soil heating pipe through a pipeline. The soil heating pipe is distributed in the soil inside the greenhouse. The greenhouse can ensure the temperature inside the greenhouse to be suitable for the growth environment of crops under the conditions of no need for heating devices, the thermal insulation effect is good, and the construction cost and operation cost are low.

Description

technical field [0001] The invention relates to an agricultural greenhouse. Background technique [0002] Greenhouses are important modern agricultural production facilities to ensure the supply of agricultural products such as winter vegetables. In order to ensure that the temperature in the greenhouse is adapted to the growth temperature of the crops, in some relatively cold areas, especially in the northeast of my country, heating settings must be set in the greenhouse. The setting of these heating facilities not only increases construction costs, but also increases energy consumption and operating costs. The use of heating facilities that use coal, crop straw, etc. as fuel will also cause environmental pollution. Contents of the invention [0003] The object of the present invention is to provide a greenhouse with low construction and operation costs, good heat preservation effect and no need for heating facilities. [0004] The purpose of the present invention is a...
