植硅体态碳(phytolith-occluded organic carbon,Phyt OC),在植硅体的坚硬外壳“保护”下,可以长时间地保存在一些土壤和沉积物中,作为一种相对稳定和“安全”的长期有效的生物固碳机制,在全球农业生态系统碳汇和气候变化中有着重要的作用,目前已经引起了越来越多科学家的关注.如何加强和提高农业生态系统中植硅体碳汇潜力是目前研究的热点和重点.Li等人研究发现水稻植株植硅体态碳产生量,不仅与其植硅体占干物质的量有关,也与植硅体封存有机碳 Phytocarbon (phytolith-occluded organic carbon, PhytOC), which can be preserved in some soils and sediments for a long time under the protection of phytolith-occluded organic carbon, as a relatively stable and “ Safety ”has played an important role in the global carbon sequestration and climate change in agro-ecosystems and has attracted more and more scientists’ attention nowadays. How to strengthen and improve the cultivation of silicon in agricultural ecosystems Carbon sink potential is the current research focus and focus.Li et al study found that rice plants produce silicon state carbon production, not only with its phytoliths accounted for the amount of dry matter, but also with the phytolithic storage of organic carbon
