摘　　要：为明确不同施肥梯度对桃树果实品质的影响,试验通过有机、无机相结合方式进行梯度试验,旨在确定有机肥对桃树的最佳用量。结果表明,与不施用有机肥比较,增施有机肥能有效提高‘小红桃’‘锦绣黄桃’果实品质。其中株施有机肥34.1 kg+复合肥1.0 kg+花后肥处理的,‘小红桃’果实可溶性固形物含量比对照提高0.67%,总酸含量比对照低0.07%,维生素C含量比对照提高60.8%;株施有机肥34.1kg处理的,‘锦绣黄桃’可溶性固形物含量比对照提高1.20%,总酸含量比对照低0.05%,维生素C含量比对照提高35.59%。2个品种的适宜有机肥用量为34.1 kg;化肥宜与有机肥同时施用,以提高其肥效。In order to clarify the effects of different fertilization gradients on peach fruit quality,the gradient experiment was carried out through the combination of organic and inorganic,in order to determine the optimal amount of organic fertilizer on peach. The results showed that compared with no application of organic fertilizer, increasing the application of organic fertilizer could effectively improve the fruit quality of ’Little red peach’ and ’Jinxiu yellow peach’. Among them,34.1 kg of organic fertilizer+1.0 kg of compound fertilizer+Post anthesis fertilizer were applied per plant. The content of soluble solid in ’Little red peach’fruit increased by 0.67%,the content of total acid decreased by 0.07% and the content of vitamin C increased by 60.8% compared with the control. When 34.1 kg organic fertilizer was applied to each ’Jinxiu yellow peach’,the content of soluble solids increased by 1.2% compared with the control,the total acid content was 0.05% lower than that of the control,the content of vitamin C was 35.59% higher than that of the control. The suitable amount of organic fertilizer for the two varieties was 34.1 kg;The simultaneous application of chemical fertilizer and organic fertilizer has good effect and can improve its fertilizer efficiency.
