In the micro-spray irrigation system, there are now many contractors who grow large households and choose micro-spray irrigation for watering. In this way of installation, one must first install the main pipe water supply pipe, connect the water supply equipment, and then install each branch pipe with a water control valve, and the water control valve is divided into thin tubes, and there are many small holes in the thin tube. After the water pressure of the water supply belt, a small water spray is formed to achieve the effect of micro spray. We can control the size of the regulating valve and the micro-spray belt to make a reasonable distribution of water supply to achieve a reasonable irrigation effect. This system can be laid in a large area, and the micro spray system is more suitable for area planting. Whether it is a large area of corn, wheat, radish, green vegetables are applicable.
