Background
With the occurrence of the crisis of global water resource shortage, how to improve the water utilization efficiency of agricultural irrigation water is an urgent problem to be solved in the world agricultural irrigation field at present as a large water resource consumption consumer in agricultural production. At present, various irrigation technologies and soil wetting processes are all characterized in that moisture drives air in soil particle pores, so that the irrigation mode inevitably causes the deficiency of soil air in root areas of crops, and the adverse effect is generated on the growth of crops.
Drip irrigation is the most advanced irrigation technology at present, only wets partial soil space of the root zone of crops, and compared with flood irrigation, the air content of the root zone of the drip irrigation crops is slightly improved, but according to the research, the drip irrigation still causes oxygen stress of the root system of the crops.

Therefore, how to solve the phenomena of air reduction, oxygen stress and lower temperature in the irrigation process is a bottleneck for restricting the further improvement of the comprehensive effect of farm irrigation.

In recent years, in the field of water-saving irrigation, the underground drip irrigation technology has been greatly popularized and applied, and the closed pipe network irrigation mode can apply proper air-entraining and heating equipment to transport air and water to the root zone of crops to change the water-air environment of the root soil, and has the advantages of improving the soil quality, promoting the yield and efficiency of crops and the like. Therefore, it is urgently needed to find a new integrated device suitable for farmland irrigation and fertilization and capable of heating by oxygen, which can not only uniformly irrigate and fertilize, but also improve the soil gas and temperature conditions in the root zone.
