摘　　要：该研究通过叶面喷施和根部灌施2种不同施用方式在桃园施用效果的研究,分析不同施用方式及不同施用量对桃树生长、果实品质及土壤理化性状的影响,结果表明:在桃树初花期、幼果期、果实膨大期、着色期,用60%的沼液喷施,桃树的单枝叶片数、新生枝长度、叶面积、百叶厚、百叶重、茎粗分别比清水对照增加52.1%、38.2%、32.9%、11.6%、12.2%、30.8%;单果重、果实硬度、可溶性固形物、Vc含量分别比清水对照增加26.7%、20.8%、30.6%、56.5%,可滴定酸含量下降49.8%,优质果率提高41.3%。沼液灌施60 kg/株土壤速效N、P、K、有机质含量分别增加36.4%、204.7%、205.4%和31.8%,土壤容重下降20.8%。In this study,two different application methods of foliar spraying and root irrigation were used to study the application effect in peach orchard,and the influence of different application methods and different application amounts on the growth,fruit quality and soil physical and chemical properties of peach trees was analyzed.The results showed that,when spraying with 60% biogas slurry in early flowering,young fruit,fruit expansion and coloring stage,compared with water spraying,the number of leaves per branch,length of new branches,leaf area,louver thickness,louver weight and stem diameter of peach trees increased by 52.1%,38.2%,32.9%,11.6%,12.2% and 30.8%,respectively.And fruit weight,fruit hardness,soluble solids and Vc content have increased by 26.7%,20.8%,30.6% and 56.5%,respectively.While the titratable acid content decreased by 49.8% and quality fruit rate increased by 41.3%.The content of soil available N,P,K and organic matter contents increased by 36.4%,204.7%,205.4% and 31.8%,respectively,and soil bulk density decreased by 20.8% under biogas slurry irrigation of 60 kg/plant.
