Abstract: In recent years, the acidification of tea garden soil has become increasingly serious due to the influences of internal and external factors. Soil acidification of tea plantation mainly manifests as soil structural deterioration, reduced fertility and increased heavy metal content. These variations can affect the growth and development of tea trees and reduce the tea quality, and may even harm human health, seriously threaten the sustainable development of tea plantation. This paper reviewed the research advance on soil acidification of tea plantations in recent years, summarized the causes, harms and improvement measures for soil acidification, and finally proposed the future research directions.

Key words: tea plantation, soil acidification, acidification cause, acidification improvement
