Abstract

The invention discloses a cyclic aeration subsurface oxygen irrigation system. The system comprises a main water delivery pipe (6), wherein, one end of the main water delivery pipe (6) is communicated with a water source, the main water delivery pipe (6) is communicated with an aeration water storage tank (1) provided with an exhaust valve (2) in parallel through a first three-way joint (7) and a second three-way joint (8), and the other end of the main water delivery pipe (6) is communicated with each water irrigation tubular billet (5) buried in soil. The cyclic aeration subsurface oxygen irrigation system is characterized in that the exterior of the aeration water storage tank (1) is connected with a venturi ejector (3) and a booster pump (4); a first water flow control valve (9) is arranged between the aeration water storage tank (1) and the three-way joint (7); a second water flow control valve (10) is arranged between the aeration water storage tank (1) and the three-way joint (8); and a third water flow control valve (11) is arranged between the three-way joint (7) and the three-way joint (8). The cyclic aeration subsurface oxygen irrigation system disclosed by the invention has the advantages of simple structure, low cost, less energy loss, cyclic aeration function and wide range of aeration ratio, and is convenient for use and management as well as maintenance and is labour-saving; and meanwhile fertilizer can be dissolved in water, and fertilizer, water and gas can be irrigated at the same time, thus utilization ratio of fertilizer can be improved, and pollution to soil and underground water can be reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to a circulation aeration underground oxygen irrigation system. Background technique [0002] Subsurface drip irrigation is one of the most advanced irrigation technologies at present. However, like other irrigation technologies, the process of subsurface drip irrigation water infiltrating the soil is a process in which the liquid phase displaces the gas phase, so that an obvious anaerobic environment can appear in the irrigated wet area. How to effectively improve the air permeability in the humid area is one of the key issues to be solved in the development of subsurface drip irrigation technology. In order to solve this problem, foreign researchers use underground drip irrigation system to transport aerated water to the root zone of crops to irrigate crops. This new irrigation technology is the recently emerging subsurface oxygen irrigation (Subsurface Oxygation)....
