Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0028] The inventor first conducted a large number of combined multi-factor orthogonal tests and single-factor tests on the flow channel structure parameters of the emitter, and took the hydraulic performance and anti-clogging performance related parameters of the emitter as assessment indicators, and initially established a zigzag irrigation method. The design theory system of the emitter, that is, the design of the internal flow channel structure of the emitter adopts the currently commonly used sawtooth flow channel structure design. Such as figure 1 The illustrated underground drip irrigation anti-root invasion emitter includes a water inlet chamber 1 containing a zigzag flow channel 7 and a water outlet chamber 6 containing a water outlet respectively arranged on both sides. Outlet positio...

Abstract

The invention provides a root intrusion protection douche for subsurface drip irrigation, relating to a subsurface drip irrigation douche, which comprises a water intake cavity with a sawtooth-shaped flow road and a water outtake cavity with a water outlet which are respectively arranged at the two sides of the douche, the water outlet is a slot water outlet. By proceeding from the physical structure of the douche, the invention adopts the structure of the slot water outlet and the structure of arranging a physical barrier inside the water outtake cavity, which not only effectively solves the problem of root intrusion, but also has the advantages of low price and no environmental pollution. Besides, the invention arranges a sieve-shaped filtering grid and optimizes the size of the sawtooth-shaped flow road, thus improving the jam resistance performance of the douche and promising the uniformity of the inside flow rate.

Description

technical field [0001] The invention relates to an underground drip irrigation emitter, in particular to a non-pressure compensation type underground drip irrigation anti-root invasion emitter. Background technique [0002] Subsurface Drip Irrigation (SDI technology for short) is a new type of high-efficiency water-saving irrigation technology developed on the basis of the increasingly perfect drip irrigation technology (Drip Irrigation, DI technology for short). It refers to a local irrigation method in which water slowly flows out through the irrigator on the buried capillary, infiltrates into the nearby soil, and then diffuses the water to the entire root layer by capillary action or gravity for crop absorption and utilization. Its characteristic is that the soil structure is less disturbed during the irrigation process, which is conducive to maintaining the loose and transparent environmental conditions of the crop root layer. At the same time, the irrigation water and f...
