Sprinkler irrigation is a water-saving irrigation technology that pressurizes irrigation water (using a pump or using the natural drop of the water source) to a sprinkler through a pipe, and ejects the water from the sprinkler, and evenly distributes small droplets to irrigate the crop. Compared with ordinary ground irrigation methods, it has the advantages of saving water by 30-50% compared with ground irrigation; maintaining the diameter of water droplets and the intensity of sprinkler irrigation can be adjusted according to the soil texture, without scouring, avoiding water, Loss of soil and fertilizer; land-saving use of sprinkler irrigation can save 7% -13% of the total area of the field and ditch land and improve land utilization; the application of labor-saving sprinkler irrigation has increased the degree of irrigation mechanization and automation and greatly reduced labor Strength, saving labor; adaptable sprinkler irrigation is not limited by the slope of the terrain and the permeability of the soil, and is suitable for irrigation in the hilly areas where the surface irrigation method is difficult to achieve. Increasing the yield of sprinkler irrigation facilitates strict control of soil moisture and maintains soil fertility.
Sprinkler irrigation has a wide range of applications and is suitable for irrigating almost all dry crops, such as cereals, vegetables, fruit trees, and medicinal materials. From the perspective of terrain, it is suitable for both plains and hills. From the perspective of soil quality, it is suitable for both highly permeable soils and low infiltration rates. Spray irrigation can be used not only for crop irrigation, but also for garden grassland and flower irrigation. At the same time, it can also be used for spraying fertilizers, pesticides, defrost, heatstroke and dust prevention. Types of sprinkler irrigation system: fixed sprinkler irrigation system It consists of water source, pump unit, pipeline system and sprinkler head. With the exception of the sprinklers, the other components of the system remain stationary throughout the irrigation season or even throughout the year. The fixed sprinkler irrigation system is easy to use, with high operating efficiency, low operating cost, less engineering land, and easy to implement automation, but with higher investment. The semi-fixed sprinkler irrigation system has the same composition as the fixed type, with its power, water pump and main pipe fixed. Branch pipes, rigid pipes and nozzles can be moved. The advantages of drip irrigation belt manufacturers are that the equipment rate is high, the investment is relatively low, but the labor intensity is large; the unit type sprinkler irrigation system is composed of various large, medium and small sprinkler irrigation units. It has the advantages of flexible mobility, strong adaptability and low investment.
