摘要/Abstract

摘要： 茶树是我国重要的经济作物,具有喜湿怕涝的特性。当前,茶树涝害机理及配套恢复措施的研究相对滞后,解析修剪等农艺措施对涝害后茶树生长的恢复具有重要意义。以受到涝害胁迫的‘金萱’茶树为试验材料,探究了水涝胁迫对茶树的影响。研究结果表明,涝害会使茶树根际微生态失衡,有害微生物在根中聚集,如厌氧细菌（Azospira、Citrifermentans等）及致病真菌（Phaeomoniellales、Gibberella等）;水涝胁迫还会降低茶树根内多种元素（Ca、K、Zn、P）的含量,抑制其转运蛋白基因表达,但会提高根内Fe含量。修剪能显著提升遭受水涝茶树的百芽质量、茎长、茎宽和叶面积,进而增加茶叶产量;其能通过增强根系对氮元素的吸收和转运进而促进茶树的恢复。

Abstract: Tea plants, as a significant economic crops in China, are characterized by their preference for moisture 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 the restoration of tea growth. Here, the effects of waterlogging stress on the 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.) and pathogenic fungi (Phaeomoniellales, Gibberella, etc.), accumulate in the roots. Meanwhile, it also decreases the expressions of related element transporter genes and element levels (Ca, K, Zn, P) in the roots of 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 root system.

Key words: Camellia sinensis, waterlogging, prune, root microorganisms, nitrogen
