摘　　要：对日光温室栽培的中油5号油桃,以每株施底肥海藻有机肥8.3 kg为对照,试验3种黄腐酸肥的增产提质效果。结果发现,每株施底肥海藻有机肥8.3 kg加黄腐酸微生物菌剂360 g;每株施底肥海藻有机肥8.3 kg,于花后坐果期、膨果期分别追施黄腐酸营养液75 g;每株施底肥黄腐酸有机-无机复混肥360 g加黄腐酸微生物菌剂360 g,于花后坐果期、膨果期分别追施黄腐酸营养液75 g,增产提质效果均不同程度地优于对照。以每株施底肥海藻有机肥8.3 kg,花后坐果期、膨果期分别追肥黄腐酸营养液75 g的处理效果最佳,单株坐果数71个,单株产量12.08 kg,果实可溶性固形物含量9.7%,可溶性糖含量8.38%,可滴定酸含量0.38%,均与对照差异显著,单果重170.06 g和Vc含量2.59 mg/100 g,与对照无显著差异。Effect of three kinds of fulvic acid fertilizer on yield and quality of nectarine Zhongyou No.5 cultivated in the greenhouse were tested,with 8.3 kg of seaweed organic fertilizer per plant as the control.The results showed that 8.3 kg of seaweed organic fertilizer and 360 g of fulvic acid microbial agent were applied to each plant;8.3 kg of seaweed organic fertilizer was applied to each plant,and 75 g of fulvic acid nutrient solution was applied at fruit setting stage and fruit expansion stage after flowering;applying 360 g of fulvic acid organic-inorganic compound fertilizer and 360 g of fulvic acid microbial agent to each plant,and applying 75 g of fulvic acid nutrient solution at fruit setting stage and fruit expansion stage after flowering,the effects of the above three methods for increasing yield and improving quality were better than that of the control in varying degrees.The effect of applying 8.3 kg of seaweed organic fertilizer per plant and topdressing with 75 g of fulvic acid nutrient solution at the fruit setting stage and fruit expansion stage after flowering was the most obvious.The number of fruit set per plant was 71,the yield per plant was 12.08 kg,the content of soluble solid,soluble sugar,and titratable acid of fruit was 9.7%,8.38%and 0.38%,respectively,which were significantly different from the control.However,the weight of single fruit(170.06 g)and the content of VC(2.59 mg/100 g)were not significantly different from the control.
