摘要:

【目的】探明生物炭和氮肥互作对盐渍化土壤氨挥发的影响。【方法】基于室内土壤培养试验，研究了仅施用生物炭、仅施用氮肥、同时施用生物炭和氮肥对不同盐渍化程度土壤的氨挥发速率与矿质态氮量的影响。【结果】添加生物炭可提升非盐渍化和中度渍化土壤pH值，但对重度盐渍化土壤pH值的影响不显著。施氮条件下，添加生物炭对非盐渍化土壤和中度盐渍化土壤的氨挥发速率产生了明显的抑制作用，氨挥发总量分别相比仅施氮处理降低了18.06%和50.88%，氨挥发速率分别降低了14.57%和43.68%。【结论】添加生物炭可显著降低非盐渍化土壤与中度盐渍化土壤的氨挥发损失。

Abstract:

【Objective】Investigating the Interactive Effects of Biochar and Nitrogen Fertilizer on Ammonia Volatilization in Saline Soils.【Method】We investigated the effects of applying biochar, nitrogen fertilizer, and their combination on ammonia volatilization rates and mineral nitrogen content in soils with varying degrees of salinity through indoor soil incubation experiments.【Result】The addition of biochar led to pH enhancement in non-saline and moderately saline soils, while its effect on heavily saline soil pH was not statistically significant. Moreover, in the presence of nitrogen application, the inclusion of biochar significantly suppressed ammonia volatilization rates in non-saline and moderately saline soils, resulting in reductions of 18.06% and 50.88%, respectively, in total ammonia volatilization compared to the sole nitrogen application. The ammonia volatilization rates were also decreased by 14.57% and 43.68% in non-saline and moderately saline soils, respectively. These findings underscore the potential of biochar to ameliorate ammonia losses in non-saline and moderately saline soils when combined with nitrogen application. 【Conclusion】The addition of biochar has been shown to have a significant impact on reducing ammonia volatilization losses in both non-saline and moderately saline soils.
