摘要
为明确葡萄霜霉病田间初始发生与孢子囊、气象因素及葡萄品种的关系。连续6年定点调查了无核红宝石、玫瑰香、蛇龙珠上的葡萄霜霉病初始发生时期,利用孢子囊捕捉器捕捉葡萄霜霉病菌孢子囊,并通过农田小型气候站监测田间气象数据,分析温度、湿度、降雨等气象因素与霜霉病初始发生的关系。结果表明在葡萄霜霉孢子囊发现后10天左右,田间始见霜霉病斑;不同品种葡萄上霜霉病的初始发生时期有所不同:红宝石发病最早,其次为玫瑰香,蛇龙珠发病最晚;葡萄霜霉病的发生与气温、相对湿度、降雨量等气候条件密切相关,其中降雨量是影响葡萄霜霉病初始发生的主导气象因子。通过对以上数据分析,本研究提出直接又简便的预测方法,为葡萄霜霉病的防控和预测测报提供依据。
To clarify the relationship between the initial occurrence of grape downy mildew and sporangia,meteorological factors and grape varieties,the initial occurrence periods of grape downy mildew of Ruby Seedless,Muscat Hamburg and Cabernet Girnischt were investigated for 6 consecutive years.A spore trap device was installed to collect the grape downy mildew spores in the air.The meteorological data of field were detected by a small climate station.The relationships between temperature,humidity,rainfall and the initial occurrence of grape downy mildew were analyzed.The results showed that downy mildew spots were seen in field after 10 days of the discovery of grape downy mildew spores.The downy mildew occurrence period of different grape varieties was different,that of Ruby Seedless was the earliest,followed by that of Muscat Hamburg fragrance,and then was that of Cabernet Girnischt.The incidence of grape downy mildew was closely related to temperature,humidity and rainfall,in which the rainfall was the main factor.Based on the above data analysis,this study proposes a direct and simple method for the prediction of grape downy mildew,which could be a basis for the prevention and control of this disease.
