Product Description
In general, the selection of irrigation pumps needs to consider many factors, such as the water quality of the water source, water flow and pressure, the topography and soil conditions of the farmland, as well as economic and environmental considerations. When purchasing and using the irrigation pump, it is necessary to carefully understand its working principle, technical parameters and operation methods to ensure its normal operation and achieve the desired irrigation effect.
The use of mechanical and power equipment, so that water through the nozzle (or nozzle) into the air, in the state of raindrops on the field irrigation method. Sprinkler irrigation equipment is composed of water inlet pipe, pump, water delivery pipe, distribution pipe and nozzle (or nozzle), which can be fixed, semi-fixed or mobile. It has the advantages of saving water, not destroying soil structure, regulating ground climate and not being restricted by terrain.
It is an irrigation method that sprays water with a certain pressure into the air and scatters it into small drops or forms mist to fall on plants and the ground with the help of pumps and pipeline systems or the use of natural water sources.
Water saving: Because sprinkler irrigation can control the amount and uniformity of water spray, avoid surface runoff and deep leakage losses, the utilization rate of water is greatly improved, generally saving 30% to 50% of water than flood irrigation, water saving also means saving power and reducing irrigation costs.
b. Labor saving: sprinkler irrigation is easy to realize mechanization and automation, which can save a lot of labor. Because of the cancellation of the field water channel, not only conducive to mechanical operations, but also greatly reduce the amount of field labor. Sprinkler irrigation can also be combined with the application of chemical fertilizers and pesticides, and can save a lot of labor, according to statistics, the amount of labor required for sprinkler irrigation is only one-fifth of the ground irrigation.
c. Improve land utilization rate: When using sprinkler irrigation, there is no need for irrigation ditches and ridges in the field, which can make full use of cultivated land and improve land utilization rate more than ground irrigation, and generally increase the cultivated area by 7% to 10%.
d. Yield increase: sprinkler irrigation facilitates strict control of soil moisture, so that soil moisture is maintained in the most suitable range for crop growth. Moreover, the dust on the stems and leaves of plants can be washed away during sprinkler irrigation, which is conducive to plant respiration and photosynthesis. In addition, sprinkling irrigation does not cause erosion and other damage to the soil, so as to maintain the soil's aggregate structure, make the soil loose and porous, good ventilation, so it is conducive to increasing production, especially for vegetables.
Strong adaptability: sprinkler irrigation has strong adaptability to various terrain, and it does not need to level the land like ground irrigation, and can be sprayed on slopes and uneven ground. Especially in the sandy soil with thin soil layer and strong water permeability, it is very suitable for sprinkler irrigation. In addition, sprinkler irrigation is not only suitable for all field crops, but also for all kinds of cash crops, vegetables, grasslands can obtain good economic results. Sprinkler irrigation has many advantages, but it also has disadvantages. Mainly because of the large investment cost, the current conditions of mobile sprinkler irrigation system is the cheapest, and the mu investment also needs 20-50 yuan/mu. In addition, it is greatly affected by wind speed and climate, when the wind speed is greater than 5.5 m/s (equivalent to class 4 wind), it can blow raindrops, reduce the uniformity of sprinkler irrigation, and it is not suitable for sprinkler irrigation. Second, when the climate is very dry, evaporation loss increases, which also reduces the effect.
