葡萄果实采后,加强田间管理,对来年的丰产稳产具有重要的怍用。一、控制病害的发生和发展1、抓紧防治霜霉病。8—9月份是葡萄霜霉病的发病高峰期,此病发展极快,在适宜条件下,几天内病斑便可布满叶片,新梢不能充分成熟,花芽分化数量减少且质量差,严重者还会造成自上而下枯死,给来年产量造成严重影响。防冶霜霉病的药剂有多种,如瑞毒霉、瑞毒铝铜、乙磷铝、甲霜灵锰锌、甲霜铜等。以甲霜灵锰锌、甲霜铜防治效果较好。
Grape fruit harvest, to strengthen field management, the next year’s high and stable yield has important use. First, control the occurrence and development of disease 1, pay close attention to prevent downy mildew. 8-9 months is the peak incidence of grape downy mildew, the disease develops very fast, under appropriate conditions, the lesion can be covered within a few days leaves, shoots can not fully mature, reduce the number of flower buds and poor quality, In severe cases, it can also cause death from above, causing serious impact on the coming year’s output. Anti-downy mildew agents have a variety of drugs, such as Rui poisonous mold, Ruoxin aluminum copper, phosphorus phosphorus, metalaxyl-manganese zinc, a cream copper. To metalaxyl manganese zinc, a cream copper control effect is better.
