Description

technical field [0001] The invention relates to the field of testing the blockage mechanism of emitters, in particular to a cycle acceleration test system and method for the blockage mechanism of emitters in drip irrigation systems. Background technique [0002] Drip irrigation is a high-efficiency water-saving irrigation technology that drips water evenly and stably into the soil in the root zone of crops through a full pipeline system. It can realize the coordinated regulation of water, fertilizer, air, heat and salt in the root zone of crops along with the water. , has become an important platform for realizing agricultural water saving and high-efficiency production, with great development potential. The emitter is the core component of the drip irrigation system, and its quality directly determines the stability of the system and the quality of irrigation water. However, due to the need for energy dissipation design and the pursuit of good hydraulic performance, the flo...
