摘　　要：为探究有机肥替代化肥对土壤性质及番薯生产的影响,该研究针对番薯的养分需求特性,按照等氮替代的方法施用有机肥,对土壤理化性质、番薯产量及品质等指标进行检测分析。结果表明,相较于仅施用化肥的对照组,商品有机肥及生物有机肥等氮替代化肥显著(P<0.05)提高土壤pH值,且在添加15 kg生物有机肥的处理中,土壤速效钾含量增加62.4%。同时,不同化肥减量处理并不会对番薯产量造成显著影响,但番薯块根中的全钾含量均得到显著(P<0.05)提升。其中,15 kg生物有机肥添加处理中的全钾含量增幅达53.1%。以上研究为有机肥替代化肥的应用推广及番薯产业的绿色可持续发展提供了重要的理论依据。To investigate the effects of replacing chemical fertilizers with organic fertilizers on soil properties and production of Ipomoea batatas,organic fertilizers were applied using the method of equal nitrogen substitution,and indicators such as soil physical and chemical properties,yield and quality of Ipomoea batatas were tested and analyzed based on the nutrient requirements of Ipomoea batatas.The results showed that,compared with the control group that only applied chemical fertilizer,commercial organic fertilizer and bio-organic fertilizers with equal nitrogen substitution for chemical fertilizers,significantly(P<0.05)increased soil pH value.The content of soil available potassium increased by 62.4%in the treatment added with 15 kg bio-organic fertilizer.Meanwhile,different chemical fertilizer reduction treatments did not have significant effects on yield of Ipomoea batatas.However,the total potassium content in storage root was significantly increased(P<0.05).Especially in the treatment added with 15 kg bio-organic fertilizer,the total potassium content increased by 53.1%.The research promotes the application of chemical fertilizer reduction by organic fertilizer and provides an important theoretical basis for the green and sustainable industry development of Ipomoea batatas.
