Embodiment Construction

[0010] The structural principle and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0011] see figure 1 , 2 3. The humidity self-regulating micro-irrigation emitter of the present invention is provided with a humidity-sensitive material control ring 3 on the periphery of each water outlet area 2 of the drip irrigation belt 1, and the humidity-sensitive material control ring 3 can use electrolytes, organic matter, and metal oxidation. made of moisture-sensitive materials such as silicon or silicon single crystals. Typical electrolyte humidity sensitive materials include LiCl; organic polymer humidity sensitive materials include PVC (polyvinyl alcohol) and LiCl mixture, butyl acetate fiber, polystyrene sulfonic acid ion exchange resin (PSS), polyimide (pl ), polydiacetylene, polypropynyl alcohol doped with sulfuric acid, etc.; metal oxide-based moisture-sensitive materials include Fe 2 o 3 ...

Abstract

The new-type drip irrigation device capable of utilizing humidity to make automatic regulation is characterized by that the water outlet region of said drip irrigation device is equipped with a control ring made of humidity-sensing material, according to the humidity of near soil said control ring whose use period is one week can be automatically opened and expansion-closed so as to control size of cross-section of the above-mentioned water outlet region of the drip irrigation device and regulate its dripping time and dripping quality, so that it not only can make the root of crops obtain enough water, but also can save water maximally.

Description

1. Technical field [0001] The invention belongs to an agricultural water-saving drip irrigation device, in particular to a humidity self-adjusting micro-irrigation dispenser. 2. Background technology [0002] At present, the water-saving drip irrigation system is realized by pressure water source, head filter, water pipeline, field filter and fertilization, sprinkler or drip irrigation pipe and fully automatic and semi-automatic control facilities. Most of the existing sprinklers adjust the water supply pressure and water output through fully automatic and semi-automatic control facilities to control the main pipe valve. The pressure compensation type emitter only ensures that the water output is basically uniform under different inlet pressures. On-demand drip irrigation in each irrigation area in the field, the current specific method is to embed moisture meters and hygrometers at regular intervals in the field soil, and use sensors to control the master control valve on t...
