Micro-nano bubble oxygenation drip irrigation system and method

Abstract

The invention relates to a micro-nano bubble oxygenation drip irrigation system and a micro-nano bubble oxygenation drip irrigation method. The system comprises a water inlet main pipe, wherein the water inlet main pipe is connected with two branches in parallel, and a first branch is sequentially connected with a water pump, a pressure stabilizing tank and a pipe pump; a spray nozzle which stretches into the pressure stabilizing tank is arranged at an inlet end of the pressure stabilizing tank, and a pressure stabilizing valve is arranged at the top of the pressure stabilizing tank; a pressure gauge is arranged on an outlet pipeline of the pipe pump; a flow regulating valve and a pressure gauge are sequentially connected onto a second branch; the two branches converge to form a water outlet main pipe; the position, at an inlet of the water pump, of the first branch is connected with an outlet of an air pump through an electromagnetic valve and an inlet of the air pump is respectively connected with a pure oxygen source and an ozone source; a one-way valve and a gas flowmeter are sequentially arranged between the pure oxygen source and the air pump; a one-way valve and a gas flowmeter are sequentially arranged between the ozone source and the air pump; the pipe pump is electrically connected with a frequency conversion cabinet, the frequency conversion cabinet is electrically connected with a power distribution box through an electromagnetic valve and the power distribution box is electrically connected with a programmable controller; the flow regulating valve, the pressure gauges, the electromagnetic valves, the gas flowmeters, the water pump, the pipe pump and the power distribution box are respectively and electrically connected with the programmable controller.

Description

technical field [0001] The invention relates to a drip irrigation system and method, in particular to a drip irrigation system and method with micro-nano bubbles and oxygen. Background technique [0002] Water and fertilizer integration technology is currently the most effective irrigation method in arid and water-scarce areas. It applies the water and fertilizer required by the crops to the root system of the crops, and has achieved good results in saving water and fertilizer and increasing production. The development and application of my country's water-fertilizer integration technology has developed to a fairly mature stage. In order to further improve the quality and yield of fruits and further increase the effect of water-saving and fertilizer-saving, it is necessary to seek new methods. [0003] The roots of crops need sufficient oxygen for aerobic respiration to maintain their own metabolism and the growth and development of the entire plant. Root hypoxia will lead ...
