根据在浙江省富阳县和武义县连续两年的观察试验,认为油茶春梢发生炭疽病原因是由于上年生枝端各器官组织内带有炭疽菌的菌丝延伸所致。4月下旬始现症状,5月上、中旬为发病高峰期。春梢发病率虽不高,但林间病春梢的绝对数大。病春梢有较强的产孢能力,所产孢子萌芽率高,是林间炭疽病的主要侵染来源之一。春末修除病春梢(剪口位于上年生枝端以下5厘米处)是综合防治,油茶炭疽病工作的重要措施。
According to two consecutive years of observation and test in Fuyang County, Zhejiang Province and Wuyi County, it was considered that the anthrax pathogen in the spring shoots of Camellia oleifera was caused by the extension of mycelia with anthrax in various organs and tissues of the last year. Symptoms appear in late April, and in May, the middle is the peak incidence. Although the incidence of spring shoots is not high, but the absolute number of forest shoots spring large. Disease spring shoots have strong sporulation ability, the spore germination rate is high, is one of the main sources of anthracnose intrusion. In the late spring to repair the disease in spring shoots (cut in the branches at the end of the year 5 cm below) is an integrated prevention and control, Camellia anthrax work important measures.
