茶园土壤酸化成因及改良措施研究和展望

摘要： 由于茶园自身及外在因素的影响,近年来茶园土壤酸化趋势日益严重。茶园土壤酸化表现为土壤结构性变差、肥力降低及重金属含量增加,进而影响到茶树的生长发育,降低茶叶的品质,甚至可能对人体健康产生危害,严重威胁茶园的可持续发展。本文回顾并梳理了近年来茶园土壤酸化方面的研究成果,综述了茶园土壤酸化的成因、危害及改良措施,并提出了该领域未来的研究方向。

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
