Irrigation technologies can be divided into the following categories:
Watering is a traditional way of irrigation. Ditching is often necessary. It was previously done by hand, and then used cattle and tractors. Plants are located at the boundary of the Dragon trench or grow on the seedbed. Along the edge of trench or seedbed, field pilot pipe or aluminum pipe can also be used for irrigation through holes on the pipe and connected to siphon canal.
2 irrigation. Irrigation is to spray water in the field through pipes. It is different from high pressure and low pressure, and can be divided into fixed type and mobile type. The fixed nozzle shall be installed in a static place. Some nozzles are installed at the height of the ground. They are mainly used for irrigation and need beautiful grassland.
3、 Spray. Micro irrigation is an irrigation form. In this form, water is evenly sprayed on the branches of crops through radiation refraction. It can not only systematically and quantitatively increase soil moisture, but also improve air humidity and adjust local microclimate. It is widely used for moisturizing and cooling of vegetables, flowers, gardens and medicinal plant plantations
Drip irrigation. Drip irrigation is an irrigation method in which a drop of water flows slowly and evenly into the soil near the plant roots. Slow drip into the soil can greatly reduce evaporation loss. If polyethylene film is added, evaporation can be further reduced. During drip irrigation, except that the soil water near the ejector is saturated, the water in other parts of the soil is unsaturated, and the soil water mainly diffuses through capillary tension
5 irrigation. In areas with high groundwater level, irrigation method has been used for many years. This is a method of artificially raising groundwater level and direct water from bottom to root.
