二氧化碳浓度升高对茶树生理代谢的影响及应对技术

大气中的二氧化碳(CO2)浓度升高是工业革命以来全球范围内最重要的生态变化之一,将直接影响植物的生长发育和代谢过程。尽管CO2浓度升高对粮食作物的影响已经得到了广泛的研究,但其对茶树等重要经济作物的影响却很少受到关注。本文回顾和总结了CO2浓度升高对茶树的初级代谢(包括光合作用、呼吸作用和碳氮代谢)和次级代谢的影响,并探讨了CO2浓度升高环境下茶叶生产过程中的应对技术,旨在为CO2浓度升高背景下茶树优质高产栽培提供一定的理论基础和科学依据。

Effects and Coping Strategies of Carbon Dioxide Enrichment on Physiological Metabolism in Tea Plant

Carbon dioxide(CO2) enrichment is one of the most important ecological changes in the world since the industrial revolution, which will directly affect the growth, development and metabolism of plants. Although the effect of elevated CO2 concentration on food crops has been widely studied, its impact on tea and other important economic crops has received little attention. The effects of elevated CO2 concentration on the primary metabolism(including photosynthesis, respiration, carbon and nitrogen metabolism) and secondary metabolism of tea plants were reviewed and summarized in this paper. The coping strategies in the tea production under CO2 enrichment were also discussed in order to provide certain theoretical basis and scientific basis for the high-quality and highyield cultivation of tea plant under the background of CO2 enrichment.
