摘　　要：采用田间病害自然鉴定和室内外仪器测定相结合的方法,研究了叶面喷布750倍的云大-120对9307、维多利亚、早熟红无核、SO4、矢富罗莎、红霞、红宝石无核和藤稔等8个葡萄品种的叶片叶绿素含量、葡萄黑痘病、霜霉病和白粉病抗性及果实主要品质的影响。结果表明:在葡萄花蕾期(4月29日)和幼果期(5月22日)2次叶面喷布750倍云大-120,供试品种的叶绿素含量均有所提高,提高幅度最大的是SO4,最小的是红霞;果实的内在品质和外在品质都有所提高,但品种之间存在一定的差异;参试品种对黑痘病、霜霉病和白粉病的抗性普遍减弱。The experiment was conducted to study the effect of foliar spraying BR-120 diluted liquid in 750 times on Chlorophyll content,the resistance of grape to Plasmopora viticola,Elsinoe amelina and Uncinula.Necator and main fruit quality of tested varieties,including 9307,Weiduoliya,Flamesee-dless,SO4,Shifuluosha,Hongxia,Ruby seedless and Fujiminor by the method of combining natural identification of disease in field with apparatus measuring inside and outside.The result indicated that two times foliar spraying BR-120 diluting liquid in 750 at flower buds and young fruit period could increase the relative content of chlorophyll.Among tested varieties,SO4 increased scope was the biggest,Hongxia was the smallest.The inner and appearance qualities of fruit had some improvement.But different variety had some difference.The resistance of different tested variety to Plasmopora viticola,Elsinoe amelina and Uncinula.Necator all decreased.
