What is the workflow of drip irrigation

The operation of the drip irrigation system begins with the extraction of water sources, which usually relies on water pumps to extract water from wells, reservoirs, rivers or other water sources. As the core power source of the drip irrigation system, the performance and efficiency of the water pump directly affect the irrigation effect of the entire system. When selecting a water pump, factors such as the depth of the water source, flow rate and required water pressure must be considered comprehensively to ensure that the water pump can meet the actual needs of the drip irrigation system.

Before the extracted water source enters the drip irrigation system, it usually needs to go through a series of treatment steps to ensure that the water quality meets the system's usage standards. The water quality treatment process generally includes processes such as filtration and sedimentation. Filtration is a key step in removing impurities from the water, which can effectively prevent impurities from clogging the dripper, thereby affecting the irrigation effect. Common filter types include screen filters, cyclone sand and gravel separators, sand filters, and laminated filters. These devices can be reasonably selected and combined according to water quality conditions and treatment requirements. Sedimentation uses gravity to settle suspended matter in the water to the bottom, further improving the purity of the water quality.

The treated water is transported to the dripper through a pipe system. The pipe system is usually composed of a main pipe, branch pipes and capillary pipes, which are responsible for evenly distributing pressurized water to each dripper. In the pipe system, some regulating equipment, such as pressure gauges, gate valves and flow regulators, may be set up to monitor and control the water pressure and flow in the pipe in real time to ensure that each dripper can get the right amount of water.

The dripper is a vital component of the drip irrigation system. Its function is to slowly release water into the soil in a dripping manner. The design of the dripper is to form energy loss, thereby reducing water pressure and making water drip out at a uniform rate. The dripper is usually installed on the soil surface or buried shallowly in the soil to ensure that water can penetrate directly to the roots of the plant. The material, size and shape of the dripper directly affect its water output and water output speed. Therefore, the water demand characteristics of the crop and soil conditions should be fully considered when selecting it.

After the water drips into the soil through the dripper, it is quickly absorbed by the soil and penetrates to the roots of the crop. The drip irrigation system has the ability to flexibly adjust according to the water demand and growth stage of the crop to achieve precise irrigation. This irrigation method not only greatly reduces water waste, but also significantly improves crop growth quality and yield.
