Description

technical field [0001] The invention relates to a pit type drip irrigation device, which belongs to the technical field of agricultural irrigation. Background technique [0002] With the gradual improvement of agricultural modernization in our country, drip irrigation has become the most effective water-saving irrigation method to solve arid and water-scarce areas. The hydraulic performance of drip irrigation emitters has always been a hot research issue, and its hydraulic performance is mainly determined by the structure of the flow channel. , many scholars at home and abroad have proposed to improve the hydraulic performance of the runner by optimizing the structure of the runner itself. The hydraulic performance of the runner is expressed by the flow index, which reflects the flow characteristic of the emitter and the sensitivity of the flow rate to the pressure head. Labyrinth channel is the classic structure of current drip irrigation channel. In order to optimize its c...
