摘要
向日葵菌核病是制约向日葵生产的重要因素之一,菌核萌发形成子囊盘和降雨因素密切相关.以内蒙古阿荣旗、巴彦淖尔市临河区和甘肃兰州安宁区为试验点,探索向日葵菌核子囊盘形成和当地气象条件的相关性.研究发现,在温度基本稳定的条件下,不同年份三个地区7月份的降雨量显著增加,8月初都观察到向日葵子囊盘的出现,向日葵菌核子囊盘形成之后是否有大面积盘腐病株出现取决于后续的降雨量和降雨频率.
Sclerotinia sclerotiorum is one of the important factors restricting in production,the apothecia generated on sclerotinia germination is closely related to rainfall condition.The paper studied the correlation between the formation of sunflower sclerotinia and local meteorological conditions with experimental sites as Arongqi and Linhe of Inner Mongolia and Anning of Lanzhou,Gansu.The results showed that based on a stable temperature,the significant increase of rainfall in July in three years,the emergence of sunflower apothecia was observed in early August,and whether there was a large area plate rot plants after sunflower nucleus formation dependents on subsequent rainfall and its frequency.
