Soil pH is an important factor limiting blueberry cultivation. In recent years, great progress has been made in the study of soil pH control technology for blueberry cultivation. In this paper, the technology and mechanism of reducing soil pH by adding inorganic elements or inorganic compounds, adding or covering acidic organic substances, applying acidic chemical fertilizers, applying biological manure or inoculating mycorrhizal fungi were reviewed. The future research on soil pH control technology of blueberry cultivation was prospected.
