Northwest arid regions are characteristic forest and fruit bases in China, but water resource shortage becomes a bottleneck restricting the development of forest and fruit industry, traditional surface drip irrigation has large evaporation loss, and the requirement of deep-rooted fruit trees is difficult to meet. At present, the underground irrigator has the main problems of low irrigation uniformity, blockage due to negative pressure sludge suction, washing of soil by pressurized irrigation and low matching degree between a soil moist body and a root system. Common emitters are pressure compensated emitters and labyrinth-flow path emitters.
For example, the pressure compensation type irrigator has high irrigation uniformity, but the elastic diaphragm of the pressure compensation type irrigator is easy to reduce performance and even age and damage under the repeated action of water pressure, the cost of the elastic diaphragm is high, and the irrigator is pre-buried near the root system of a fruit tree for a long time and is inconvenient to replace.

When the common irrigator is used on the ground surface, the outlet is communicated with the atmosphere to form free outflow, and if the common irrigator is directly embedded in a soil body for use, the instantaneous negative pressure generated by the change of the water pressure in the pipeline easily causes the blockage of the outlet by absorbing mud. For example, chinese patent document CN201805777U discloses a pre-buried type irrigation device. The device is favorable to the absorption of plant root to water in the deep soil, but when the pressurization water injection is irrigated, easily causes to erode destruction to root system and soil, and the degree of consistency of watering is not high.

The drip irrigation emitter is beneficial to the uniformity of irrigation, but the micropore flow channel is easy to generate biological and physical blockage when the root of a fruit tree is irrigated. For another example, chinese patent document CN102550368A discloses an underground type fountain root irrigation emitter. The irrigator is used for carrying out Yongquan root irrigation on the jujube trees, and the volume of a wetting body of the irrigator is 6.7-10.4% of the volume of a main distribution area of the jujube tree root system.
The irrigation emitters are point source or linear source infiltration when irrigating, the matching degree of the soil wetting body formed after irrigation and the distribution of the root system of the fruit tree is not high, the root system is deviated to grow for a long time, the wind resistance of the fruit tree is weakened, and the utilization rate of irrigation water also has a larger promotion space.
