Water mist irrigation system for greenhouse planting

Abstract

The invention discloses a water mist irrigation system for greenhouse planting. The water mist irrigation system comprises a greenhouse main body, a water storage tank and a heating boiler; the outerwall of the heating boiler is provided with a spiral heat exchange tube; the side wall of the greenhouse main body is provided with a plurality of box bodies; the top ends of the inner cavities of thebox bodies are provided with a plurality of first spray heads which are uniformly distributed; metal fin groups are arranged below the plurality of first spray heads; the bottom of the box body is provided with a water outlet pipe; the water outlet pipe is connected with the water storage tank through a pipeline; the first spray heads are connected with one end of the spiral heat exchange tube through a pipeline; the other end of the spiral heat exchange tube is connected with the water storage tank through a pipeline; and the side walls of the two sides of the box body are respectively provided with an air supply opening and a mist outlet. According to the invention, plants are watered by using mist, so that the watering is uniform and sufficient, the water is not accumulated locally, and the water consumption is low. In addition, the water in residual mist is recycled, and the water resource is saved.

Description

technical field [0001] The invention relates to the field of planting greenhouses, in particular to a water mist irrigation system for planting in greenhouses. Background technique [0002] At present, in order to increase the output of agricultural production, greenhouses have been widely used in the field of agricultural planting due to their function of keeping heat and moisturizing. In the process of greenhouse planting, due to the isolation of the contact between the planting soil and the outside world, in order to reduce the labor intensity during natural rainfall, the cover film is generally not collected, resulting in the rainwater not falling on the soil covered by the greenhouse, resulting in the soil covered by the greenhouse. Insufficient water needs to be irrigated with tap water, etc., but the existing way of watering is watered by spraying, which consumes a lot of water resources, and when watering the cultured animals on the multi-layer culture rack, there is...
