Underground micro-pipe irrigation system capable of adjusting wetting range

Abstract

The invention relates to an underground micro-tube irrigation system capable of adjusting a wetting range, which comprises a water level control box, a capillary tube communicated with the water level control box and a plurality of sleeves fixedly connected and communicated with the capillary tube, the capillary tube and the sleeves are positioned in soil, and the communication point of the capillary tube and the water level control box is lower than a water inlet of the water level control box in the height direction. A water inlet of the water level control box is communicated with a water supply branch pipe through a floating ball valve; and the sleeve is vertically arranged, a micro pipe is arranged in the sleeve, and the upper end of the micro pipe extends into soil above the sleeve. The water level in the water level control water tank is automatically adjusted through a floating ball valve in the water level control water tank, the water level in a sleeve can be controlled according to the communicating pipe principle so as to adjust the irrigation wetting range, and timely adjustment can be conducted according to the growth condition of crop roots; and the micro-pipe irrigation technology is carried out by utilizing the capillary action principle, the problem of blockage of the underground irrigation emitter is well solved, water can be accurately supplied at proper time and proper amount, and the irrigation uniformity and accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of irrigation, in particular to underground micropipe irrigation, in particular to an underground micropipe irrigation system with adjustable wet range. Background technique [0002] At present, less than 50% of the cultivated land in my country can be irrigated, but only about 3% of the area that can be irrigated uses high-efficiency irrigation technology, and most of them use traditional irrigation methods, namely border irrigation and irrigation. Furrow irrigation, etc. have low irrigation uniformity, serious water waste, low water use efficiency, and backward technology. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides an underground micropipe irrigation system that can adjust the wet range, which improves the uniformity of irrigation, and the irrigation system is buried underground, which prevents a large amount of water from evaporating, an...
