摘要
为了解不同材料生物质炭施用对果园土壤质量的改良效果,采用田间试验,研究了不同生物质炭施用对果园土壤性状及活性有机碳的影响。结果表明:施用生物质炭提高了果园土壤含水量及pH值,降低了土壤容重,提高了土壤微生物生物量碳含量。相比对照,生物质炭处理的土壤含水量提高1.05%～55.77%,pH值提高0.03～1.68个单位,土壤容重降低5.00%～32.50%,土壤微生物生物量碳含量提高10.24%～90.94%。不同材料生物质炭对土壤含水量、容重、pH值及微生物生物量碳含量的影响幅度不同。
In order to understand the improvement effect of different biochars on soil quality in orchard, a field experiment was conducted to study the effects of different biochars on soil properties and labile organic carbon. The results showed that the application of biochars to the orchard soil not only enhanced field moisture holding capacity, pH value, but also increased the content of microbial biomass carbon(MBC), while decreasing soil bulk density. Compared with the control, the moisture content, pH value and MBC content of the biochar treated soil increased by 1.05%-55.77%, 0.03-1.68 unit and 10.24%-90.94%, respectively, while soil bulk density decreased by 5.00%-32.50%. Altogether, the effects of different biochars on soil water content, bulk density, pH value and MBC content were different.
