Background
Water, fertilizer and gas in soil are main environmental factors restricting the growth and development of crops, and the change of any single factor can affect the growth and development of the crops, so that the phenomena of slow growth, growth stopping and even death of the crops are caused. However, in the irrigation process, the infiltration of irrigation water can expel air in soil pores to cause the problem of transient oxygen deficiency in a root zone, the air permeability in the root zone soil is poor, the growth of a plant root system and the absorption of nutrients can be inhibited, and the yield and the quality of crops are further influenced.

The key problem of success or failure of water-fertilizer-air coupling irrigation is that if the mixed air is not uniformly mixed with the water-fertilizer solution or large bubbles are formed, water-air layering can occur during pipeline transportation, which affects the uniformity of air outflow and even causes the situation that the air is difficult to enter soil. At present, the air injection is generally finished by adopting a Mazzei Venturi ejector produced by the Mazzei Injector company in America abroad, and the gas mixing rate (the ratio of gas phase to gas-liquid two-phase flow total volume) is generally maintained at about 12 percent due to the influence of the structure and the energy consumption.
By setting the air entrainment rate increment tests (0, 12% and 19%) with tomatoes and peppers as test crops, research finds that the product yield increases with increasing air entrainment rate, and therefore, the following conclusion is drawn: the irrigation air-mixing rate of crops is improved, and better crop yield can be obtained.
