Essential Filters for Drip Irrigation

Release Date:

2019-09-23

Water sources must be filtered, typically using 100-mesh nylon or stainless-steel mesh, or a 120-mesh disc- or screen-type filter. This is critical for the proper operation of a drip-irrigation system. Filters should be cleaned regularly, and the end of the drip line should be periodically opened and flushed—generally once a month. Before fertilization, a fertilization plan should be designed based on the specific crop being grown, and the appropriate fertilizers should be prepared. For each irrigation zone, the required amount of fertilizer for each application should be accurately measured and ready according to the fertilization plan. Drip irrigation, as one of the most water-efficient irrigation methods, has attracted considerable attention from farmers. In recent years, it has received unprecedented emphasis and promotion in China, with a rate of development that has far exceeded expectations. Drip irrigation is a water-delivery technique in which pressurized water is conveyed through a drip-irrigation pipeline system to lateral laterals, and then delivered via emitters—such as drippers, emitter holes, or drip tapes—installed along the laterals, releasing water in the form of small, uniform, and slow droplets directly into the soil to meet the water needs of crops. It is a form of localized irrigation. Because the flow rate of each emitter is low and water infiltrates the soil slowly, under drip-irrigation conditions only the soil immediately beneath the emitter remains saturated, while the surrounding soil remains unsaturated. Soil moisture primarily enters and spreads through capillary action. With proper control of irrigation timing, there is virtually no percolation loss; moreover, the area of the soil surface that remains wet during drip irrigation is small, significantly reducing evaporation losses and resulting in very substantial water savings.

Filters must be cleaned regularly, and the end of the drip irrigation tubing should be opened periodically for flushing—typically once a month. Before fertilization, develop a fertilizer application plan based on the specific crops being grown and prepare the necessary fertilizers. For each irrigation zone, stock the exact amount of fertilizer required for each application according to the plan. Drip irrigation as a water-saving measure Relatively One of the best irrigation techniques has attracted considerable attention from farmers. In recent years, drip irrigation has garnered significant attention in China and has been promoted on an unprecedented scale, with a rate of development that has surpassed all expectations. Drip irrigation is a water-delivery technique in which pressurized water is conveyed through a drip-irrigation pipeline system to lateral laterals, and then delivered via emitters—such as drippers, orifices, or drip tapes—installed along the laterals, allowing water to drip evenly and slowly into the soil to meet the water requirements of crop growth. It is a form of localized irrigation. Due to the small flow rate of the drip emitters, water infiltrates the soil slowly; consequently, under drip irrigation, only the soil directly beneath the emitter remains saturated, while all other soil zones remain unsaturated. Soil moisture primarily infiltrates and diffuses under the influence of capillary suction. With proper control of irrigation duration, percolation losses are virtually eliminated. Moreover, drip irrigation results in a small wetted surface area on the soil surface, which effectively reduces evaporation losses, leading to remarkably significant water-saving effects.
