【摘要】 根系分泌物是植物对大气CO2浓度升高响应的调节器,它能活化土壤养分元素、调节微生物区系组成,在根际微生态系统中扮演重要角色。本文综述了大气CO2浓度升高及其导致的温度上升引起根系分泌物数量和组成上的变化,讨论了这种变化与土壤微生物的关系和对全球C循环的贡献,并根据现状提出了今后的研究方向。更多还原

【Abstract】 Root exudates are products the plant generates in responding to CO2 enrichment. They can activate soil nutrient elements and regulate composition of the soil microbiota, thus playing an important role in the rhizospheric microecosystem. Effects of elevated atmospheric CO2 and consequent rise in temperature on composition and amounts of root exudates were summarized in this paper. And some issues were discussed based on current status of the research.更多还原
