Greenhouse micro-spray irrigation system

Abstract

The invention discloses a greenhouse micro-spray irrigation system which comprises stormwater channels on two sides of a greenhouse, a stormwater tank, a water purifier and a micro-spray pipeline. Thestormwater tank is in through connection with the stormwater channels, the water purifier is mounted on one side of the stormwater tank, a water inlet pipe of the water purifier extends into the stormwater tank, a water outlet pipe of the water purifier extends into a water storage tank, the micro-spray pipeline comprises an inner pipe, a hollow outer pipe and a non-woven geotechnical cloth coating layer, gaps are uniformly distributed on the inner pipe, a space between the inner pipe and the hollow outer pipe is filled with sand, the outside of the hollow outer pipe is coated with the non-woven geotechnical cloth coating layer, the micro-spray pipeline is embedded into soil of two sides of a vegetation ridge in the greenhouse, an inlet of the inner pipe is hermetically connected with a pump outlet, a pump inlet extends into the water storage tank, and an outlet of the inner pipe is connected with the water storage tank. According to the irrigation system, soil can be rapidly irrigated through a structure and an embedded position of the micro-spray pipeline, and the system can overcome the shortcomings that water spraying of a common micro-spray pipe is blocked by stems and leaves, diseases and insect pests are increased, surface humidity is high, and bottom humidity is insufficient.

Description

technical field [0001] The invention relates to the field of vegetable greenhouses, in particular to a micro-spray irrigation system for greenhouses. Background technique [0002] Greenhouse soil irrigation generally includes sprinkler irrigation, micro-sprinkler irrigation, drip irrigation and infiltration irrigation, etc. Each type has its own advantages and disadvantages. When sprinkler irrigation and micro-sprinkler irrigation are used to replenish water for greenhouse plants, some of them will be sprayed to the ground due to the obstruction of the stem. The surface of stems and leaves increases the pests and diseases of stems and leaves, which is not conducive to water saving. At the same time, because sprinkler irrigation and micro-sprinkler irrigation spray water from the upper part, the humidity of the soil surface is high, and the bottom layer is not moist enough; while the drip irrigation speed is slow and the water consumption of infiltration irrigation is large. ...

At the same time, because sprinkler irrigation and micro-sprinkler irrigation spray water from the upper part, the humidity of the soil surface is high and the bottom layer is insufficient; while the drip irrigation speed is slow and the water consumption of infiltration irrigation is large

So far there is no greenhouse irrigation system that can be fast, economical and avoid the defects of sprinkler irrigation and micro-sprinkler irrigation
