在稻麦轮作地区,麦类赤霉病的初侵染源主要来自春季稻桩上的子囊孢子.但是对稻桩如何带菌,有不同的看法.如苏州地区农科所曾用带菌麦粒撒于稻田,使第二年稻桩带菌率明显高于对照,从而说明土壤带菌有一定作用.近年来有报道证明水稻田长期淹水,病菌在稻田土中存活期短,不能越夏越冬.吴治身同志提出病种子为主要病菌来源等等.同时,弄清麦收后病菌以什么状态存在和玉米、水稻等寄主植物在病菌侵染循环中的作用,对研究病害的流行、预测也是必要的.因此,1979～1982年进行病菌周年活动状态的研究.
In the rice-wheat rotation area, the primary source of Fusarium head blight came from the ascospores on the spring rice pile, but there are different opinions on how the rice pile carries the bacteria, for example, In paddy field, the second year of rice piles carrying rate was significantly higher than that of the control, indicating that soil borne bacteria have a certain role in recent years have been reported to prove that paddy rice fields flooding, bacteria in paddy soil survival time is short, can not over summer wintering. Comrade put forward the source of the disease as the main source of germs, etc .. At the same time, to clarify what state after the wheat harvest bacteria and corn, rice and other host plants in the pathogen infection cycle, the prevalence of disease research, prediction is necessary. , 1979 ~ 1982 annual activities of bacteria in the state.
