摘　　要：通过设置有机肥配施土壤调理剂、生物质炭、生石灰、阿美滋等不同处理,分析土壤pH、有机质含量、产量和品质等指标。结果发现,有机肥配施生石灰可快速地提升土壤pH,但在有机质含量、产量和品质等指标的提升上效果不佳;有机肥配施生物质炭可显著提高土壤pH、有机质含量、甘薯产量和品质等指标;有机肥配施土壤调理剂可提高甘薯产量和还原糖含量等指标;单施生物质炭可提高土壤pH、有机质含量、甘薯产量和品质等指标,但相对而言,配施有机肥效果更佳。因此,在甘薯土壤酸化治理过程中,可选用有机肥配施生物质炭来提高其产量和品质。In this study,by setting different treatments such as organic fertilizer combined with soil conditioner,biochar,quicklime and amezi,the indexes of soil pH,organic matter content,yield and quality were analyzed.It was found that organic fertilizer combined with quicklime could rapidly improve the pH value of soil,but the effect of organic matter content,yield and quality was not good;organic fertilizer combined with quicklime biochar could significantly improve soil pH,organic matter content,sweet potato yield and quality;organic fertilizer with soil conditioner could improve sweet potato yield and reducing sugar content and other indicators;single application of biochar could improve soil pH value,organic matter content,sweet potato yield and quality and other indicators,but relatively speaking,the effect of combined application of organic fertilizer was better.Therefore,in the process of sweet potato soil acidification,organic fertilizer and biochar could be used to improve its yield and quality.
