摘　　要：为减少黑穗醋栗果园化肥使用量,明确最佳化肥减量配施生物有机肥比例,本研究设置5个施肥处理(100%化肥、75%化肥+25%生物有机肥、50%化肥+50%生物有机肥、25%化肥+75%生物有机肥、100%生物有机肥)和1个不施肥对照,研究不同化肥减量配施生物有机肥对“绥研1号”黑穗醋栗树体生长发育、果实品质及产量的影响。结果表明:不同比例的化肥配施生物有机肥对株高、冠幅、果实大小和果穗长度、产量和经济效益均有明显促进作用;单施有机肥和化肥配施生物有机肥,增加了果实硬度、可溶性固形物、可溶性糖和VC含量,降低了可滴定酸含量。50%化肥+50%生物有机肥为最佳配施比例。In order to reduce the amount of chemical fertilizer used in blackcurrant orchard,and to determine the optimal reduction of chemical fertilizer and the proportion of bio-organic fertilizer addition,five fertilization treatments were designed,induding 100%chemical fertilizer,75%chemical fertilizer+25%bio-organic fertilizer,50%chemical fertilizer+50%bio-organic fertilizer,25%chemical fertilizer+75%bio-organic fertilizer,100%bio-organic fertilizer,and the control was no fertilization treatment.The effects of reducing fertilizer and applying bio-organic fertilizer on the growth,fruit quality and yield of black currant"Suiyan No.1"were studied.The results showed that plant height,crown width,fruit size,ear length,yield and economic benefit were significantly improved under the treatments of different proportions of chemical fertilizer combined with bio-ogical fertilizer.Fruit hardness,soluble solids,soluble sugar and VC content were increased and titrable acid content was decreased under the treatments of single organic fertilizer and chemical fertilizer combined with biological organic fertilizer.The optimal proportion was 50%chemical fertilizer+50%bio-organic fertilizer.
