生物质炭对紫色土耕地土壤中溶解性有机物含量和组成特征的影响OA北大核心CSCDCSTPCD
Effects of biochar application on content and characteristics of dissolved organic matter in arable land of pur-ple soil
选取位于长江上游低山丘陵区的四川盐亭石灰性紫色土和重庆忠县中性紫色土的两种典型耕地(旱地和菜地)土壤,添加0.5%∽3.0%生物质炭并经过老化作用,研究生物质炭添加对土壤中可水提的溶解性有机物(DOM)性质的影响.DOM的含量与组分特征分别以溶解性有机碳(DOC)浓度和光谱学特征参数表征.结果表明,石灰性和中性紫色土旱地不添加生物质炭的对照土壤中DOM的平均含量分别为43、65 mg DOC·kg-1,相应菜地的对照土壤分别为110、105 mg…查看全部>>
This study characterized dissolved organic matter(DOM)in two typical arable lands of calcareous and neutral purple soil(dry land and vegetable field)that is abundantly distributed in Sichuan hilly area. Effects of biochar application(at rates of 0.5%∽3.0%)on the concentration and composition of soil DOM was studied after three-months of dry-wet alternate aging process. The content and compositional characteristics of DOM were characterized by the concentrati…查看全部>>
