Problems solved by technology

[0002] Drip irrigation is one of the most advanced water-saving irrigation technologies in the world. According to the location of water distribution, drip irrigation is divided into two forms: surface drip irrigation and underground drip irrigation. Underground drip irrigation means that the dripper directly drips water into the soil layer of the crop root zone. Part of the water is absorbed and utilized by crops. Although underground drip irrigation has obvious advantages in terms of convenient field operations and management, it has disadvantages such as easy to be blocked by sediment and root hairs of crops, inconvenient maintenance and high engineering cost.

Abstract

The invention discloses a movable underground drip irrigation apparatus comprising main pipes, branch pipes, capillary pipes and plug-in type underground drip irrigation apparatus characterized by that, the front end of the pipe is connected to a water storage equipment with pressure pump, the main pipe near the water storage equipment is connected in turn to a filter and an air evacuation valve, the main pipe is connected to a plurality of branch pipes through a rapid branch joint and a quick-speed reducer union, each branch pipe is connected with at least two capillary pipes, each of which comprises at least a capillary pipe section, which are coupled with express connector for easy loading and unloading, and are provided with 20-30 flow controllers in uniform distribution.

Description

Technical field: [0001] The invention belongs to the water-saving irrigation technology, in particular, it is suitable for non-dense planting economic crops in arid and water-deficient hilly areas, such as tobacco, melons and fruits, medicinal materials and flowers. Background technique: [0002] Drip irrigation is one of the most advanced water-saving irrigation technologies in the world. According to the location of water distribution, drip irrigation is divided into two forms: surface drip irrigation and underground drip irrigation. Underground drip irrigation means that the dripper directly drips water into the soil layer of the crop root zone. Part of the water is absorbed and utilized by crops. Although underground drip irrigation has obvious advantages in terms of convenient field operations and management, it has disadvantages such as easy to be blocked by sediment and root hairs of crops, inconvenient maintenance and high engineering cost. In general, according to ...
