The pollution of heavy metals in tea garden soil is one of the environmental problems that have attracted much attention in recent years.With the rapid development of tea industry,the pollution of heavy metals in soil has become an important factor restricting the quality of tea and the safety of agricultural products.As a kind of acid-loving plant,tea plant has a certain selectivity for the absorption of heavy metals in soil,and this selectivity will affect the content of heavy metals in tea.The study on the migration and transformation behavior of heavy metals in tea garden soil is helpful to formulate scientific and reasonable soil management measures and reduce the potential effects of heavy metals on ecological environment and human health.The migration and transformation of heavy metals in tea garden soil is affected by many factors,including soil factors,plant factors,environmental factors,agricultural management and other factors.However,there are still some problems to be solved urgently.Future research can deeply study the micro-mechanism in the soil-tea system,systematically clarify the water transmission mechanism caused by rainfall and irrigation,and identify the relationship between tea quality and the content of heavy metals in tea garden soil,so as to provide more scientific support for the sustainable development of tea industry.
