| 英文摘要 | PurposeBiochar, as a stable carbon-rich material, has received concentrated attention in soil quality improvement, especially in soil carbon sequestration. This study aimed to find out the effects of biochar application on carbon stock in the whole salt-affected soil ecosystems.MethodsThis study was conducted in a heavy salt-affected soil, aiming at investigating biochar application effects on salt-affected soil organic carbon (SOC), soil inorganic carbon (SIC), as well as plant (Tamarisk chinensis) biomass carbon stocks.ResultsAfter 4 years of biochar application of 30, 60, and 90 t ha-1, the results showed that biochar increased soil total organic carbon (STOC) stock by 54.78, 160.44, and 198.33%, and biochar increased soil total inorganic carbon (STIC) stock by 13.85, 11.04, and 16.03%, respectively. Further, it is calculated that biochar increased native SOC (extra SOC excluding biochar carbon) by 7.63, 66.15, and 56.90% and SIC by 13.55, 10.44, and 15.12%, respectively. In addition, biochar application accelerated Tamarisk chinensis growth by 10.03, 23.54, and 11.28%, respectively. Combining all the SOC, SIC, and plant-derived carbon, it is concluded that biochar application enlarged salt-affected soil-vegetation ecosystem carbon stock by 23.36, 47.80, and 58.10%, respectively.ConclusionThese results indicated that applying biochar in salt-affected soil can enhance salt-affected soil-vegetation ecosystem carbon stocks. The mechanisms behind this phenomenon may be that biochar improves soil water content and bulk density, which promotes Tamarisk chinensis growth. Biochar has a good potential to improve salt-affected soil quality and mitigate climate change. |
