The drip irrigation system is mainly composed of three parts: the first hub, the pipeline and the dripper.
1. The first hub: including water pump (and power machine), fertilization tank, filter, control and measuring instrument, etc. Its function is to pump water, fertilize, filter, and send a certain amount of water into the main pipe with a certain pressure.
2. Piping: including main pipes, branch pipes, capillary pipes and necessary adjustment equipment (such as pressure gauges, gate valves, flow regulators, etc.). Its role is to deliver pressurized water evenly to the dripper.
3. Dripper: Its function is to make the water flow through the tiny pores, form energy loss, reduce its pressure, and make it drip into the soil in a drop-by-drop manner. Drippers are usually placed on the soil surface and can also be buried shallowly for protection.
Use 1-5 plastic thin tubes with a diameter of 4-6 mm and a length of 55 meters as the capillary, and start drilling at 5 meters at the head of the capillary, the aperture is 1.2 mm, and the distance between the two holes is 35 cm, and the capillary is separated from the capillary. 2 meters is appropriate. When using, first insert the head of the capillary directly into the pool, and then fix it. Using the principle of reverse siphon, the water enters the porous capillary through the short water delivery pipe. After there is water flow at the end of the capillary and there is no debris, it is blocked, and then each capillary is closed. Place the crops near the crops at a distance of 2 meters, and then move the crops in each row to another row for irrigation after the irrigation is suitable.
This kind of simple drip irrigation is suitable for greenhouse planting and mountains, furrows, small plots and places with poor water conservancy conditions, and has a good drought resistance effect.
This simple drip irrigation method has the following significant advantages: First, the utilization rate of water is high, which can reach 90%, which saves 50%-60% of water than sprinkler irrigation. Second, the water storage project is simple, and only a pressure head of 0.5-1 meters can meet the irrigation needs. The reservoir can be a built-in pond, a water tank or bucket on a water truck, or a pond can be dug in a hilly area and covered with anti-seepage plastic sheeting. The third is low investment and high efficiency. According to the calculation of 5 capillary tubes, 5 acres can be drip irrigation every day. Watering and management are convenient, and everyone can make them. If local holes are found to be blocked during the irrigation process, they can be solved by puncturing immediately.
