The liquid must be filtered or settled before it enters the water pipeline. This is the most commonly used method. The precipitation and filtration equipment must be checked and cleaned frequently to keep them in good technical condition.
Appropriately increase water delivery capacity to reduce irrigation system blockage.
Place the water outlet of the dripper/sprinkler upwards, and clean the capillary regularly to reduce clogging.
Chemical treatment of drip irrigation water. 0.001% chlorine solution (that is, household bleaching powder thin liquid) into irrigation system for 20 minutes every day, it can significantly reduce the viscous deposits on the pipe wall and prevent clogging.
Measure the water quality and avoid it contains iron, hydrogen sulfide, and tannins, which can easily cause blockage.
Phosphate fertilizer cannot be applied through irrigation system. Phosphorus will react with calcium in the irrigation water to form a precipitate that can clog the dripper. Other fertilizers also must be completely soluble in water.
