摘要：为了探明新梢管理对葡萄果实品质的影响，研究了不同新梢间距（10cm、15cm和20cm）和主副梢管理措施（主梢一次成梢副梢全去除、主梢一次成梢副梢留一叶、主梢一次成梢副梢留两叶、主梢二次成梢副梢全去除、主梢二次成梢副梢留一叶和主梢二次成梢副梢留两叶）对设施‘87-1’葡萄成熟期果实品质的影响，2017~2018连续两年的测定结果表明：新梢间距与葡萄可溶性固形物含量存在极显著相关，新梢间距20cm可溶性固形物含量最高，但与单粒重、可滴定酸和香气含量不存在相关性；主副梢管理与单粒重、可溶性固形物含量、可滴定酸和香气含量均不存在相关性。结论：建议设施‘87-1’葡萄新梢间距设置20cm，主梢一次成梢副梢留1叶绝后摘心。
