硅肥施用对土壤和陆地植物碳储量及碳通量影响的Meta分析
Effects of silicon addition on carbon storage and carbon flux of soil and terrestrial plants:a meta-analysis
硅肥作为重要的元素肥料在农林业生产中得到了广泛应用,且生态系统中硅循环与碳循环密切相关,然而陆地生态系统碳循环如何对硅添加进行响应仍不清楚。本研究使用Meta分析研究了全球范围内陆地生态系统中碳库及碳通量对硅添加的响应,并探究了对该响应存在影响的因素。结果表明,硅添加显著增加植物地上碳储量 19.7%、地下碳储量 17.36%、植物总碳储量 26.7%、凋落物碳储量 8.26%及植硅体碳储量 21.75%,同时使土壤有机碳库增加 7.22%。此外…查看全部>>
Silicon fertilizer has been widely used as an important element fertilizer in agricultural and forestry production,and the silicon cycle in the ecosystem is closely related to the carbon cycle.However,it is still unclear how the carbon cycle of terrestrial ecosystems responds to silicon fertilizer application.Here,a meta-analysis method was used to quantify the response ratio of C pools and fluxes in terrestrial ecosystems worldwide to silicon fertilizer app…查看全部>>
