technical field

The utility model relates to the field of drip irrigation, in particular to an energy-saving nozzle for water conservancy drip irrigation.

Background technique

Drip irrigation is an irrigation method that drips the water and the moisture and nutrients required by the crops into the soil in the root zone of the crops evenly and slowly through the piping system and the irrigator installed on the capillary tube according to the water requirements of the crops. Drip irrigation does not damage the soil structure, and the water, fertilizer, air, and heat inside the soil are always kept in a good condition suitable for crop growth. The evaporation loss is small, there is no ground runoff, and there is almost no deep leakage. It is a water-saving irrigation method. The main feature of drip irrigation is that the amount of irrigation water is small, and the flow rate of the emitter is 2-12 liters per hour. Therefore, the duration of one irrigation is longer and the cycle of irrigation is shorter, which can achieve frequent irrigation with small water; the required working pressure is low, and it can be more Accurately controlling the amount of irrigation water can reduce ineffective evaporation between trees and will not cause water waste; drip irrigation can also be managed automatically.

The existing nozzles for drip irrigation do not save water as a whole. First, the water output cannot be controlled. After the main valve is closed, the nozzles will still drain the water in the pipeline, which is not conducive to water saving as a whole.
