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 abooster 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 withthe 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) througha 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 insufficient oxygen by supplying air to the root zone has always been a concern of producers and researchers. People have long realized the benefits of soil aeration on the theoretical and experimental levels, but due to the lack of suitable air injection equipment, it is difficult to implement field applications. The concept of ventilating the soil was first put forward by Enyeart. The earliest experiment began in the 1980s. In 1979, Daigger and others began underground aeration experiments on potatoes and carrots. They used air compressors to perforate the water hose on the buried side wall. With injected air, the results show that aeration treatment can improve the quality of the crop, the yield of first-class potatoes is more, and the length of harvested carrots i...
