Abstract

The invention discloses a root irrigation device. The root irrigation device comprises a water irrigator which is a cylindrical member, the water irrigator is provided with a water inlet, the side wall of the water irrigator is provided with a maze runner, one end of the maze runner is communicated with the water inlet, and the other end of the maze runner is communicated with an inner cavity of the water irrigator. The maze runner is a wavy maze runner transversely coiling in the side wall of the water irrigator. The root irrigation device can enable water to fully enter the roots of crops, irrigation water is high in utilization efficiency, the runner in the water irrigator is long, discharge section area is large, and the runner unit border is parabola-shaped, so that impurities can flow through the runner along with the water flow and anti-blockage performance is good. The flow state index of the hydraulic characteristics is smaller than 0.5, energy dissipation and turbulence effect is good, and high irrigation uniformity within a certain operation pressure range is achieved; service life is longer than 20 years, and manufacturing cost is reduced by more than 20%.

Description

technical field [0001] The invention belongs to the technical field of wide-row economic crop irrigation in arid and semi-arid areas, and specifically relates to a root irrigation device, which is used to solve the water-saving irrigation of wide-row economic crops in water-deficient areas. Background technique [0002] The shortage of water resources is a problem facing the world, especially in arid and semi-arid regions, how to effectively use limited water resources and improve the utilization rate of irrigation water is an urgent problem to be solved. At present, in the water-saving irrigation technology, micro-irrigation has the advantages of water saving, energy saving, high efficiency, and increased production. It has developed rapidly and has been widely used in economical fruits, vegetables, flowers and other economic crops. It has broad development prospects. The emitter is an important component in the micro-irrigation system. The hydraulic performance and anti-cl...
