Abstract:Tea plants,asasignificant economic crops inChina,arecharacterized bytheir preference formoisture and vulnerability to waterlogging. Currently,there is few research concerning the damage caused by waterlogging to tea plants and the post-waterlogging recovery measures,so the analysis of agronomic measures such as pruning is of great significance to therestoration oftea growth.Here,the effects of waterlogging stressonthe growth of‘JinXuan’ tea plants were analyzed,and disclosed that it can result in disruption of the rhizosphere micro-ecological equilibrium in roots of tea plants. Harmful microorganisms, such as anaerobic bacteria (including Azospira, Citrifermentans,etc.)andpathogenic fungi (Phaeomonielles,Gbberella,etc.),ccumulateintheroots.Meanwhile, it also decreases the expressions ofrelated element transporter genes and element levels (Ca,K,Zn,P)intherootsof tea plants,while increases the content of Fe.The pruning approach can significantly increase the hundred-buds weight,length, widthand leaf area of the third leaves of waterlogged tea plants,thereby increasing the tea yield. It could promote the recovery of tea plants by enhancing the absorption and transport of nitrogen by the rot system.
