日本的水田二茬种麦时,往往残存着不少稻株,赤霉病菌(Gibberella Zeae)在残留的稻株上形成子囊壳,这样飞散的子囊孢子在第一次传染过程中起着很大的作用。笔者于1967—1969,1991年间在种麦场,对残存稻株上赤霉病菌子囊壳的形成状况作了调查,同时对麦类赤霉病的发生、飞散子囊孢子采集数及气象的关系进行了探讨,认为它们之间有相关关系。
During the second cropping of paddy field in paddy fields in Japan, many rice plants often remain. Gibberella Zeae forms the capsid shell on the remaining rice plants. As such, the scattered ascospores play a large role in the first infection Role. In 1967-1969 and 1991 years in the species of wheat field, the residual rice plants on the status of Fusarium bacteria shell formation were investigated, at the same time on the occurrence of wheat scab, the collection of astigmatism and the relationship between the number of astigmatism The discussion, that there is a correlation between them.
