technical field

The utility model relates to an underground irrigation device, which belongs to the technical field of agricultural water-saving irrigation.

Background technique

Traditional irrigation methods do not take into account crop growth and root development, resulting in extremely inefficient water use. By controlling irrigation, it can not only provide better growth conditions for crops, but also achieve the purpose of saving water. Water-saving irrigation is of great significance.

In recent years, agricultural water-saving irrigation has developed rapidly. The irrigation equipment used in water-saving irrigation includes: sprinkler irrigation, micro-sprinkler irrigation, drip irrigation, infiltration irrigation or underground drip irrigation. Although sprinkler irrigation, micro-sprinkler irrigation, drip irrigation, and seepage irrigation have good water-saving effects, because they are carried out on the ground, there is still the problem of water loss caused by surface water evaporation after irrigation; underground drip irrigation is a kind of water-saving agricultural irrigation. Very good choice, device and method for subsurface irrigation (87104234), subsurface irrigation system for plants (00136562.2), pulse subsurface irrigation system (201110074183.8), subsurface irrigation system (200310119540.3), subsurface irrigation with local control of water in the root zone without pressure System (03108051.0), water cable, water cable underground irrigation system and its application (200910071473.X), a buried pressure spring root irrigation irrigator (201110411698.2) and other patents provide methods and systems for underground irrigation, but these Most of the underground drip irrigation systems need to be buried in the ground in advance, and cannot be plugged and unplugged according to irrigation needs. The position and depth are fixed, and the depth cannot be changed with the growth of crops, so that the crop roots can absorb underground water to achieve the best effect; or it is easy to absorb soil particles. Wait, cause the emitter to block.
