Aeration underground drip irrigation system

Abstract

The invention discloses an aeration underground drip irrigation system which comprises a water source, a delivery main pipe (6), a delivery branch pipe (10) and an irrigation capillary (11), wherein a booster pump (5) is connected in series with the delivery main pipe (6). The aeration underground drip irrigation system is characterized in that an aeration chamber (1) is connected in parallel with the delivery main pipe (6), a micropore aeration part (7) is arranged in the aeration chamber (1), an air compressor (2) is communicated with the aeration part (7) in the aeration chamber (1) through a gas cylinder (3) and a ventilation hose (8) with a one-way valve (9), and a branch ventilation pipe (14) communicated with the aeration chamber (1) is arranged between the one-way valve (9) and a gas flow control valve (13). The aeration underground drip irrigation system can realize the three functions of ordinary underground drip irrigation, aeration underground drip irrigation and simple underground ventilation through water gas supply and valve control, has simple structure, low cost, less energy loss, controllable aeration ratio, wide aeration range, convenient use, management and maintenance and labor saving, and simultaneously can dissolve fertilizer into water, simultaneously irrigate the fertilizer, the water and gas, improve the utilization efficiency of the fertilizer and reduce the pollution for soil and underground water.

Description

Technical field: [0001] The invention relates to the technical field of agricultural irrigation, in particular to an aerated underground drip irrigation system. Background technique: [0002] Solving the problem of oxygen deficiency by supplementing air to the root zone has always been a concern of producers and researchers. The benefits of soil aeration have long been recognized theoretically and experimentally, but field application has been difficult to implement due to the lack of suitable air injection equipment. The concept of aeration to the soil was first proposed by Enyeart. The earliest experiments began in the 1980s. In 1979, Daigger et al. started the experiment of underground aeration on potatoes and carrots. They used air compressors to drill holes in the side wall of the ground. With air injection, the results showed that the aeration treatment improved crop quality, with higher yields of first-class potatoes and greater lengths of harvested carrots. Bussche...
