Water curtain cultivation system capable of geological circulation of groundwater and artificial recharge of rainwater

Abstract

There is provided a water curtain cultivation system capable of a geological circulation of groundwater and an artificial recharge of rainwater. The system according to the present invention comprises: a greenhouse (10) including an inner house (11) and the outer house (12); a water curtain space (13); a water curtain forming pipe (20) installed above the water curtain space in a length directionof the inner house; a groundwater supplying unit (30) including a groundwater supply hole (31) to supply the groundwater at a position proximate to the house where the groundwater is supplied to the water curtain forming pipe; a groundwater supplying unit (30) which pumps groundwater from a groundwater supply hole (31) near the greenhouse (10) and supplies to the water curtain forming pipe (20); a groundwater returning unit (40) which collects the groundwater injected from the water curtain forming pipe (20) for forming water curtain into a storage tank (43), and returns the collected groundwater to the under ground by a sill hole (46) and a alleviation hole (47) both distanced from the groundwater supply hole (31); and a rainwater supplying unit (50) including: a rainwater collection channel (51) formed longitudinally at a lower position outside of the outer house, and a rainwater supply pipe installed to be operatively connected to the rainwater collection channel and the groundwater return and storage tank.

Description

technical field [0001] The invention relates to a geological circulation water curtain cultivation system capable of artificially recharging rainwater. It utilizes the geothermal energy existing in the ground to greatly save the heating cost of facility cultivation in winter. Excessive use leads to insufficient groundwater and uses it as a stable heat source. Background technique [0002] As we all know, the cultivation of vegetables, fruit trees, flowers and other crops in facilities such as plastic greenhouses and glass greenhouses (hereinafter referred to as "greenhouses") is called facility cultivation. Regarding facility cultivation, the most suitable environment for crop growth is artificially created. , and in a short period of time produce and market better crops than those in the open field for sale, so as to maximize profits and allow year-round cultivation, so it is widely implemented in rural areas. [0003] However, the most important thing in protected cultiva...

Problems solved by technology

Therefore, this technology has a problem that the temperature of the groundwater used in the formation of the water curtain is not uniform, or the temperature of the groundwater is low and cannot be used in the formation of the water curtain.
