摘要：

霜霉病是山葡萄的主要病害。通过对葡萄园气象条件与霜霉病的多年观测，我们对山葡萄霜霉病的发病规律有了进一步的认识，发现在一定的气候条件下病害的潜育期不超过24小时，比前人揭示的病害潜育期明显缩短。同时，发现在某一品种寄主下的病原菌，在品种间的传播能力有显著差别。为此在防御措施上提出了新的见解。

Abstract:

Downy mildew is the main disease of Vitis amurensis Rupr.We had a further knowledge of downy mildew by many years observation of the downy mildew and the meteorologic conditions of the vineyard.We found that the incubation period of downy mildew was not longer than 24 hours on certain climate conditions,shorter than what people knew before.Meanwhile we found that the abilities of the germ in a certain strain transmited to other strains had marked difference,and so ,we put forward a new idea about how to prevent and cure Vitis amurensis Rupr. downy mildew.
