Micro-sprinkler Irrigation System in Greenhouse

Micro-sprinkler irrigation system refers to an irrigation system in which the emitters are used to irrigate crops in the form of spray water. Commonly used emitters in micro-sprinkler irrigation systems include various micro-sprinkler heads, micro-spray belts, spray guns, etc. Micro-sprinkler irrigation systems using micro-sprinklers in greenhouses generally hang the micro-sprinklers upside down on the greenhouse frame to implement irrigation to avoid the impact of the micro-sprinkler irrigation system on other field operations.

The use of micro-sprinkler irrigation systems in greenhouses saves labor and water
It can be topdressed or sprayed with water, and it is easy to realize automatic control. At the same time, due to the large contact area between sprayed water and air, the use of micro-sprinkler irrigation can significantly increase the humidity in the greenhouse, reduce the temperature in the greenhouse, and adjust the greenhouse field climate, which is conducive to high temperature and dryness. Continuous growth of seasonal crops. However, the greenhouse is a closed production environment that completely relies on the micro-sprinkler irrigation system for greenhouse crop irrigation. In the low temperature and humid season, it is easy to cause problems such as excessive air humidity in the greenhouse, which increases the chance of crop disease. At the same time, some crops bloom or set fruit. Open water irrigation is also taboo during this period, so the greenhouse micro-sprinkler irrigation system should be used with restrictions. Usually, the greenhouse micro-sprinkler irrigation system is used in combination with the greenhouse drip irrigation or pipe irrigation system. The drip irrigation or pipe irrigation system is the main one, and the micro-sprinkler irrigation system is used as supplementary irrigation or to adjust the temperature and space field climate.

Greenhouse micro-sprinklers used in the rotating micro-sprinkler and diffusion micro-sprinkler. Rotary micro-sprinkler is mainly used for supplemental irrigation, scattering micro-sprinkler is often referred to as atomizing nozzle, and refractive atomizing nozzle and centrifugal atomizing nozzle points refractive atomizing nozzle working pressure is low, the average diameter of the water droplets of 150 μm, generally applicable to humidification and cooling and irrigation both occasions; centrifugal atomizing nozzle ("ten") Centrifugal atomizing nozzle ("ten" nozzle atomizing nozzle) high working pressure, water droplet atomization (droplet average diameter of 70 um), atomization uniformity is high, suitable for greenhouse humidification and cooling. Greenhouse use of micro-spray nozzle should be with anti-drip device to prevent micro-spray nozzle or fittings connected to the drip of water on the crop hazards.
 micro-sprinkler belt micro-irrigation system using micro-sprinkler belt as the irrigation system of the irrigator. Micro spray belt is a kind of irrigation directly on a thin-walled plastic hose that can be flattened to process the water out of small holes for irrigation, one of the characteristics of this micro spray belt can be used as drip irrigation, and can also be used as a micro-sprinkler irrigation. Covered in the ground under the membrane, the micro-spray belt water upward jet to the membrane, under the cover of the membrane evenly dripping people in the soil, can be formed similar to the effect of drip irrigation; will be laid directly in the water can be formed similar to the rain of the micro-sprinkler ground
