近年来葡萄种植越来越多，不少葡萄种植户反映现在葡萄产量虽高，但果实品质不好、入口酸涩、口感差，并且葡萄叶片稀薄、不够绿。这是为什么？根据宇花灵技术团队分析认为，这多半是农药、激素使用泛滥、管理比较粗放造成的，要想提高产量又提提高品质，葡萄管理在原有的基础上应用宇花灵技术。
1．抽穗期管理。为了促进抽穗拉长花穗，可在葡萄抽穗时用宇花灵6号每瓶兑水300至500斤连续喷施两次。宇花灵6号属于营养型拉花产品，能有效的促进植株花穗拉长，拉出的花穂长度较适宜。
2．坐果前管理。此阶段要及时补充树体所需的有机营养，可用宇花灵1号每瓶兑水300至500斤连续喷施两次，培育健康的树体，延缓植株衰老，有利于提高果实的座果率和品质。
3．保果期管理。葡萄谢花后要进行保果，提高坐果率，可用宇花灵1号进行保果，为果实提供充足的养分，利于果实膨大，同时防止果实脱粒而影响产量和品质。
4．坐果后管理。为了避免嫩芽与果实争夺养分，采用“一滴两喷”技术。可以用宇花灵2号1组兑水300斤至400斤连喷2次，控制新梢徒长加速老熟，缩短节间，免人工摘侧芽，减少病害的发生，促叶片绿厚促果实着色均匀。
5．落叶前管理。葡萄属于落叶果树，要注意树体营养的积累，可喷施两次宇花灵2号以积累养分，促进抽芽统一整齐，对第二年形成花蕾也有很好帮助，可以促进来年花芽分化的形成，让第二年出来花芽多、叶芽少。
特别注意：葡萄开花期间比较敏感，建议不要喷施任何花肥。
