① The most commonly used method is to filter or precipitate the liquid before entering the water pipeline. It is necessary to regularly inspect and clean the sedimentation and filtration equipment to maintain their good technical condition Properly increase the water delivery capacity and reduce system blockages Place the dropper outlet facing upwards and regularly clean the capillary tube to reduce blockages Chemical treatment is applied to drip irrigation water, and 0.001% chlorine solution (i.e. household bleach powder dilute solution) is poured into the drip irrigation system for 20 minutes every day. It can significantly reduce the sticky deposits on the pipe wall and prevent blockage Measure water quality and avoid using water droplets containing high levels of iron, hydrogen sulfide, and tannic acid, as this can easily cause blockages Phosphorus fertilizer cannot be applied through drip irrigation systems. Phosphorus reacts with calcium in irrigation water to form sediment, which clogs the drips. Other fertilizers must be completely dissolved in water before drip irrigation fertilization can be carried out.
