水稻白叶枯病近年来在广东、湖南、江西、湖北、安徽、江苏、浙江諸省普遍发生。根据1954年的調查,此病在湖北鄂城阳新兩县內相当严重,減产1—2成。1955年此病发生是在六月下旬,与去年在六月下旬发病情况大致相似,但自七月中旬后由于干旱,因此病害比去年輕些。根据过去文献报导,認为病土是此病傳染的主要来源。此病的发病規律还未清楚,因此首先迫切要求了解病害的侵染来源及其傳播途徑,由此进一步可作为防治此病的依据。
Rice bacterial blight in recent years in Guangdong, Hunan, Jiangxi, Hubei, Anhui, Jiangsu, Zhejiang provinces generally occur. According to the 1954 survey, the disease was quite serious in the counties of Yangxin and Hsien in Hubei Echeng, with a decrease of 1-2%. The disease occurred in late June in late 1955 in much the same way as it did last year in late June. However, since mid-July drought was worse than last year. According to reports in the past literature, soil disease is considered to be the main source of infection. The pathogenesis of this disease is not clear, so the first urgent need to understand the source of infection and its transmission of the disease, which can be further used as a basis for the prevention and treatment of the disease.
