Soil acidification in tea gardens is becoming an increasingly important factor that limits the health of tea plantation soil and the quality of teaproduced.However，there is currently a lack of a systematic summary of the currentstatus， mechanisms and regulatory pathways of soil acidification in teaplantation，which restricts the high -quality development of the tea industry. This article focused on the analyzes the status of soil acidification in tea plantations in China. It systematically explained the internal mechanisms and external factors of soil acidification in the teaplantations，and analyzed the impact of soil acidification on tea treegrowth，soil materialcycling，and ecosystem processes. In response to the goal of tea garden acidificationimprovement，effective regulation pathways for tea garden acidified soil wereproposed，aiming to provide a basis for the healthy management of tea garden soil and the green and sustainable development of the tea industry.
