Root system plays an important role in plant life activities,which not only supports plant growth,but also serves as an important organ for plants to absorb water and nutrients.In recent years,soil compaction becomes more and more serious and permeability is poor,which limits the growth of roots and affects the growth of crops.Soil oxygen content is the key factor to determine the normal growth and development of crops.Some researches showed that using reasonable measures of increasing oxygen can effectively increase the oxygen content in rhizosphere,improve soil fertility and improve crop yield and quality.In this paper,some conventional methods of increasing oxygen in production and the effect of increasing oxygen on plant growth and development were summarized,in order to lay a foundation for the in-depth study of rhizosphere aeration cultivation.
