The invention relates to an underground water,
fertilizer and gas integrated
irrigation system, and belongs to the field of
irrigation management. The underground water,
fertilizer and gas integrated
irrigation system comprises a
water source, a water and
fertilizer coupling system, an air-entrapping system, an
active transport system, an irrigation system and a
control system, wherein the
water source comprises a running water inlet
pipe opening and a
check valve; the water and fertilizer
coupling system comprises a water
inlet valve, a fertilizer
mixing tank, a fertilizer mixing valve, a fertilizer
storage tank, a flow meter, a filter, a fertilizing pump and a water
check valve; the air-entrapping system comprises an
air compressor and an
electromagnetic valve; the
active transport system comprises a transport main
pipe; the irrigation system comprises an irrigation main
pipe, an irrigation
branch pipe, an irrigation hollow billet and a water dropper; and the
control system comprises a
soil humidity control circuit and an
atmospheric pressure test circuit. According to the underground water, fertilizer and gas integrated irrigation system, a certain amount of water and a certain quantity of a fertilizer are provided according to the requirements of
crop growth; the root of a
plant is ventilated to meet the condition that the root is subjected to aerobic
respiration to maintain
metabolism and growth and development of the overall
plant; the use amount of water and the use quantity of the fertilizer can be effectively reduced; the management is optimized; the labor force is reduced; and the yield is increased.
