What is the difference between micro-sprinkler irrigation and traditional irrigation?

Micro-sprinkler irrigation is an irrigation method between sprinkler irrigation and drip irrigation.

Micro-sprinkler irrigation is an irrigation method that provides irrigation water to the soil in the root zone of crops by means of low pressure and small flow spray. Micro-sprinkler irrigation technology is the general name of equipment, system design, system matching and operation management related to micro-sprinkler irrigation.

Micro-sprinkler irrigation has some similarities with drip irrigation and sprinkler irrigation, but there are also obvious differences. It has its own characteristics.

(1) In micro-sprinkler irrigation, the arrangement of micro-sprinklers is very random, unless the spacing between fruit trees is very small, mainly single sprinkler spraying, which belongs to local irrigation. The concept of combination uniformity commonly used in sprinkler irrigation is rarely used in practice.

(2) The requirements for the working characteristics of the micro-nozzle are high. Micro-sprinkler generally does not rely on nearby sprinklers to compensate its precipitation, and can only cover a certain range at a very low position and low elevation angle. At the same time, it is necessary to meet the requirements of different spraying diameters, different rainfall intensities and soils one by one without sacrificing uniformity.

(3) The utilization rate of irrigation water can be further improved through reasonable selection and use of micro-sprinklers. Generally speaking, the water saving of sprinkler irrigation lies in reasonably controlling the irrigation depth, reducing the deep leakage of irrigation water in the field, and emphasizing the uniformity of sprinkler irrigation within the irrigation range.
