Buried type agricultural irrigation system capable of adjusting osmotic concentration

Abstract

The invention relates to a buried type agricultural irrigation system capable of adjusting osmotic concentration. The irrigation system comprises a main pipeline, a secondary pipeline, a drainage portand a regulating valve, wherein the drainage port is formed in the secondary pipeline, the regulating valve is arranged on the joint between the drainage port and the secondary pipeline, a first semi-permeable membrane is arranged on the joint between the main pipeline and the secondary pipeline, a second semi-permeable membrane is arranged on the joint between the secondary pipeline and the drainage port, the regulating valve is connected with a regulating water tank, the regulating water tank regulates the concentration of an aqueous solution in the secondary pipeline, the first semi-permeable membrane is used for taking water from the main pipeline, the second semi-permeable membrane is used for irrigating the outside through the drainage port, the irrigation system further comprises amonitoring system, the monitoring system further comprises a flow instrument, a first flow velocity meter, a second flow velocity meter, a third flow velocity meter and a control meter, the first flow velocity meter, the second flow velocity meter and the third flow velocity meter measure the water velocities on the first semi-permeable membrane, second semi-permeable membrane and regulating valve respectively, the flow instrument detects the amount of water discharged from the drainage port, and the control meter controls the regulating valve to adjust the irrigation speed and irrigation amount of the irrigation system.

Description

technical field [0001] The invention relates to the field of agricultural irrigation, in particular to a buried agricultural irrigation system capable of adjusting osmotic concentration. Background technique [0002] With the advocacy of conservation-oriented thinking, the awareness of agricultural water-saving irrigation has become more and more accepted and valued by the majority of farmers. Therefore, in farmland irrigation projects, the thin dew irrigation for rice and other crops involves water saving issues. The so-called thin dew irrigation refers to thin water, shallow irrigation, and often exposed fields. As a result, water-saving irrigation valves that look like fire hydrants are quietly seen in the fields, and water-saving or waterproofing of fields can be realized by means of such water-saving valves. However, in the prior art, water saving is often limited to water saving during irrigation, that is, water saving is only considered from how to control the amount...

Problems solved by technology

[0004] In view of the existing technology, water saving is often limited to water saving during irrigation, that is, water saving is only considered from how to control the amount of water required for irrigation, and water saving is not considered from the aspect of how to improve the efficiency of irrigation. On the contrary, it leads to the problem of waste of water resources. The present invention provides a buried agricultural irrigation system with adjustable osmotic concentration
