摘要/Abstract

摘要： 为了解生物黑炭施用对果园土壤质量的改良效果,采用田间试验研究了不同生物黑炭施入量对果园土壤性状及活性有机碳的影响。结果表明:施用生物黑炭提高了果园土壤含水量、总氮含量及pH值,降低了土壤容重,提高了土壤微生物生物量碳含量。与对照相比,生物黑炭处理的土壤含水量及总氮含量分别提高3.26%~25.61%和61.22%~87.76%,pH值提高0.03~0.30个单位,土壤容重降低13.13%~19.38%,土壤微生物生物量碳含量提高84.34%~107.55%。

Abstract: To understand the soil quality change in orchard system, field experiments were conducted to study the effect of biochar application on soil properties and labile organic carbon. The results showed that biochar application to the orchard soil not only increased microbial biomass carbon (MBC) content, but also enhanced field moisture holding capacity, pH value, total N level of the soil,while decreasing soil bulk density. As compared to the control, the moisture content, pH value, total N and MBC concentration of the biochar treated soil increased by 3.26%-25.61%, 0.03-0.30 unit, 61.22%-87.76% and 84.34%-107.55%, respectively. And soil bulk density decreased by 13.13%-19.38%.

Key words: Biochar, Soil properties, Labile organic carbon, Orchard
