摘　　要：通过田间对比试验,研究控释BB肥一次性基施对设施草莓产量、品质及肥料利用率的影响。结果表明,在等氮条件下,控释BB肥一次性基施处理可显著提高设施草莓的产量,较对照处理和常规施肥处理的增产幅度分别为31.7%和4.2%,且可以明显提升草莓的糖酸比,使草莓的口感更浓。控释BB肥一次性基施处理下肥料相对利用率比常规施肥处理提高8.7%。因此,推广应用控释肥料对农业化肥减量增效、莓农节本增收具有重要意义。A field contrast experiment was conducted to study the effects of one-off basal application of controlled release blend bulk fertilizers on the yield,quality and fertilizer utilization rate of greenhouse strawberry.The results showed that one-off basal application of controlled release blend bulk fertilizers could significantly improve the yield of strawberry.Under the treatment of controlled release blend bulk fertilizers,the yield of strawberry was increased by 31.7%and 4.2%compared with the control and conventional fertilization treatment.In addition,one-off basal application of controlled release blend bulk fertilizers could significantly improve the sugar acid ratio of strawberry and give the strawberry a more intense sweet flavor.The fertilizer utilization rate of strawberry under the treatment of one-off basal application of controlled release blend bulk fertilizers was increased by 8.7%compared with the conventional fertilization treatment.Consequently,the popularization and application of controlled release blend bulk fertilizers has important significance for reducing use level and increasing the efficiency of agricultural fertilizer,and increasing the income of the strawberry farmers.
