Sprinkler irrigation technology refers to the use of special equipment to pressurize water, or use the natural drop of water to send pressurized water to the field through a pressure pipe, and then spray it into the air through a nozzle to disperse it into small water droplets, which are evenly distributed on the farmland to achieve irrigation. Purpose. Sprinkler irrigation is suitable for irrigating all dry crops, such as grains, vegetables, fruit trees, etc. It is suitable for both plains and hills and mountains; in addition to irrigation, it can also be used for spraying fertilizers and pesticides, antifreeze and anti-dry and hot wind.

Sprinkler irrigation technology is a water-saving irrigation technology between sprinkler irrigation and drip irrigation. Low-pressure pipes are used to send water near the roots of the crops, and the water is sprayed on the soil surface or above the crops for irrigation through micro-sprinklers. It has the advantages of both sprinkler irrigation and drip irrigation, and overcomes the main disadvantages of both. Sprinkler irrigation is full-scale irrigation, which wets the entire irrigated area, while micro-spraying generally only wets the local area around the crop; in the way of irrigator water, drip irrigation wets a local area of ​​soil in the form of droplets, while micro-spray is sprayed with raindrops to wet a local area of ​​soil. Micro-spraying can also increase the air humidity and adjust the field microclimate; the micro-sprinkler has a larger aperture, which has stronger anti-clogging ability than drip irrigation. Because it operates at low pressure and mostly local irrigation, it is more water-saving than spray irrigation; Irrigation sprinklers have larger apertures than drip irrigation, and are more resistant to clogging than drip irrigation, and provide faster water supply. The effect of increasing production and saving water for some cash crops is very significant.

Infiltration irrigation technology is to irrigate the roots of plants through a pipe network buried under the surface and an infiltration irrigation irrigator. The water slowly moistens and spreads in the soil to moisten part of the soil, which belongs to local irrigation. This irrigation method can overcome the shortcomings of easy aging of the ground capillary, prevent man-made damage or loss of the capillary, and facilitate field farming. It is mainly suitable for fruit tree irrigation and facility agricultural crop irrigation. The current engineering practice is to pass the irrigation water through the micropores (cracks, foaming holes) on the wall of the low-pressure infiltration irrigation pipe from the inside to the outside in a sweaty state, and then pass through the soil particles around the pipe wall, and the pores between the particles absorb water. The soil spreads to supply water to the roots of the crops, and the whole process of irrigation of the crops can be realized continuously at one time.
