What are the grape water-saving irrigation methods
Grapes are a drought-resistant fruit tree, most suitable for growth in areas with rainfall of 600-800 millimeters. If we do a good job of soil and water conservation in these areas, we can still achieve a certain yield even without irrigation throughout the year. At present, countries around the world have conducted extensive research on water-saving irrigation methods for vineyards, which can reduce the water consumption for grape irrigation by half while ensuring the yield and quality of grapes. Let's take a look.
Surface Irrigation
The common surface irrigation method is furrow irrigation. Traditional furrow irrigation involves pouring water into the furrows, which is neither accurate nor convenient, and also causes water loss due to leakage. Currently, the use of siphon or gate pipes abroad can improve the utilization rate of field water by 5%-10%. There is also a film irrigation, also known as film hole irrigation, where furrows are formed on the film. Water flows into the holes on the film and seeps into the soil. This method has high irrigation utilization rate, can save water by 25%-35%, and effectively increase yield by 15%-20%. It does not require other facilities and is adaptable.
Sprinkler Irrigation
Sprinkler irrigation is a commonly used water-saving irrigation method, which involves spraying water through the air. The advantages of sprinkler irrigation are high irrigation level, less arable land, labor-saving, and strong adaptability to terrain. However, it has the drawbacks of being highly affected by wind and high equipment investment. In China, fixed pipe sprinklers, semi-mobile pipe sprinklers, rolling sprinklers, and clockwise sprinklers are widely used.
Drip Irrigation
Drip irrigation is a precise irrigation method. It uses small plastic pipes to deliver irrigation water directly to the roots of each crop. Water drips slowly from the drip heads. Only the areas that need water are irrigated, thus irrigating the crops rather than the soil. It also keeps the crop roots' moisture in an optimal state for a long time, saving water and increasing yield. However, the disadvantage is that the inlet hole of the drip head has slow water flow, which can easily get clogged. Therefore, irrigation water must be carefully filtered and treated to prevent clogging of the irrigation devices. Common methods include fixed ground drip irrigation, semi-fixed ground drip irrigation, film mulch drip irrigation, and underground drip irrigation.
Seepage Irrigation
Seepage irrigation is similar to low drip irrigation, except that the accumulated water is replaced with an irrigation device buried underground. The water in the accumulator does not flow out drop by drop like a drip emitter but seeps out slowly, so the accumulator is less likely to get clogged like a drip emitter.
Subsurface Irrigation
Subsurface irrigation is used to control the groundwater level. During irrigation, the groundwater level rises to the active root zone, while the ground surface remains monotonous, which is very water-saving. When not irrigating, the water level drops. This method has significant limitations and can only be used when there is an impermeable layer below the active root zone.
