Micro-sprinkler irrigation is an irrigation method. It supplies irrigation water to the soil in the root zone of crops in the form of low-pressure and small-flow spraying. Micro-sprinkler irrigation technology is a general term for comprehensive technologies, which related to the irrigation method of micro-sprinkler irrigation. Such as equipment, system design, system matching, and operation management.
Micro-sprinkler irrigation has some similarities with drip irrigation and sprinkler irrigation. But there are also obvious differences. And it has its own characteristics.
The arrangement of micro-sprinklers in micro-sprinkler irrigation is very arbitrary. Unless the distance between fruit trees is very small. It is mainly single-spraying, which belongs to local irrigation. The concept of combined uniformity commonly used in sprinkler irrigation is rarely used in practice.
The requirements for the working characteristics of the micro-spray head are high. Micro-sprinklers generally do not rely on nearby sprinklers to compensate for their precipitation, and can only cover a certain range at low elevation angles at very low locations. At the same time, the requirements for various spraying diameters, different rainfall intensities and soils must be met one by one without sacrificing uniformity.
We can improve the utilization rate of irrigation water through the reasonable selection and use of micro-sprinklers. The water saving of general sprinkler irrigation lies in the reasonable control of irrigation depth, reducing the deep leakage of irrigation water in the field, and emphasizing the uniformity of sprinkling water within the irrigation range.
