How Can Floppy Sprinkler Irrigation System Facilitate Our Lives?
With the continuous development of agriculture and the acceleration of automation and modernization, the floppy sprinkler irrigation system has gradually entered the mass market and has become popular among farmers. The fundamental reason is that the use of floppy sprinkler irrigation system can not only save manpower but also improve efficiency. This blog will mainly discuss floppy sprinkler irrigation system.
What is sprinkler irrigation？
Sprinkler irrigation is an irrigation method in which water with a certain pressure is sprayed into the air by means of a water pump and pipeline system or by using the drop of a natural water source to disperse into small droplets or form a mist to land on plants and the ground.
What is a sprinkler irrigation system？
The sprinkler irrigation system is a water conservancy facility that takes water from the water source, transports it, and distributes it to the field to implement sprinkler irrigation. It consists of three parts: water source engineering, water transmission and distribution channels or pipelines, and spraying equipment.
A complete sprinkler irrigation system generally consists of sprinklers, pipe networks, headers and water sources.
✅Sprinkler: The sprinkler is used to disperse the water into droplets, and spray it evenly on the planting area like rain.
✅Pipe network: Its function is to transport and distribute the pressure water to the planting area that needs to be irrigated. It is composed of pipes of different pipe diameters, divided into main pipes, branch pipes, capillary pipes, etc., through various corresponding pipe fittings, valves and other equipment to connect all levels of pipelines into a complete pipe network system. The pipe network of modern irrigation systems mostly uses plastic pipes such as PVC pipes and PE pipes that are easy to construct, have good hydraulic properties and will not rust. At the same time, necessary safety devices, such as intake and exhaust valves, pressure limiting valves, and drain valves, should be installed in the pipe network as required.
✅The first part: its function is to take water from the water source, pressurize the water, water quality treatment, fertilizer injection and system control. Generally include power equipment, water pumps, filters, fertilizer applicators, pressure relief valves, check valves, water meters, pressure gauges, and control equipment, such as automatic irrigation controllers, constant pressure frequency conversion control devices, etc. The number of the first equipment may increase or decrease depending on the system type, water source conditions and user requirements. For example, in the case of using urban water supply systems as water sources, pressurized water pumps are often not required.
✅Water source: Well springs, lakes, reservoirs, rivers and urban water supply systems can all be used as sprinkler irrigation water sources. Throughout the growing season, the water source should have a reliable water supply guarantee. At the same time, the water quality should meet the requirements of irrigation water quality standards.
What are features of sprinkler irrigation system?
✅Improve land use efficiency: When sprinkler irrigation is used, irrigation ditches and borders in the field are not needed. It can make full use of arable land than ground irrigation, improvingland use efficiency, and generally increasing the arable area by 7%-10%.
✅Strong adaptability: Sprinkler irrigation has strong adaptability to various terrains, whetherslopes or uneven ground. Especially in the sandy soil with thin soil layer and strong water permeability, it is extremely suitable for sprinkler irrigation. In addition, sprinkler irrigation is not only suitable for all field crops, but also can obtain good economic effects for various cash crops, vegetables, and pastures. Sprinkler irrigation has many benefits, but there are also disadvantages. It is greatly affected by wind speed and climate. When the wind speed is greater than 5.5 m/s (equivalent to level 4 wind), raindrops can be blown away, which reduces the uniformity of sprinkler irrigation and is not suitable for sprinkler irrigation. Secondly, when the climate is very dry, the evaporation loss increases, which will also reduce the effect.
✅Labor saving: sprinkler irrigation is easy to realize mechanization and automation, which can save labor. As a result of the cancellation of the field water conveyance ditches, it is not only conducive to mechanical operations, but also greatly reduces the amount of field labor. Sprinkler irrigation can also be combined with chemical fertilizers and pesticides, and it can save a lot of labor. According to statistics, the labor required for sprinkler irrigation is only one-fifth of surface irrigation..
✅Increase production: Sprinkler irrigation is easier to strictly control the soil moisture, so that the soil moisture can be maintained in the most suitable range for crop growth. Moreover, it can wash away the dust on plant stems and leaves during sprinkler irrigation, which is beneficial to plant respiration and photosynthesis. In addition, sprinkler irrigation does not produce damage to the soil such as erosion, so as to maintain the aggregate structure of the soil, makingthe soil loose and porous, and having good aeration, which is beneficial to increase production, especially the effect of increasing vegetable production.
✅Save water and improve utilization efficiency: Because sprinkler irrigation can control the amount and uniformity of spray water, avoid ground runoff and deep leakage loss, so that the water utilization rate is greatly improved. Generally, it saves 30%-50% of water compared with flood irrigation. It means saving power and reducing irrigation costs.
