| 摘 要： | 白菜軟腐細菌Erivinia aroideae不能在田間土壤中越冬,但能在未分解的病菜根和病菜叶中越冬。用病根及病叶等所作的堆肥中不能分离出具有致病力的軟腐細菌。菜窖中的废菜叶为軟腐細菌越冬及繁殖的主要場所之一。春季由麻蝇(Sarcophaga sp.)及花蝇(Fannia sp.)传布到田間的感病作物上,另外也可以由蜜蜂(Apis mellifera L.)、叶蜂(Athalia rosae L.)及小菜娥(Plutella maculipennis curtis)等繼續在白菜間传布。此外窖中移出的菜种株上亦带有病原細菌。因此認为菜窖中及田間殘菜根的越冬細菌是軟腐病的初次侵染源

| Abstract: | It has been experienced that in Peking immediately after the soil is defrozen in the spring, no trace of soft-rot bacteria can be isolated from the field soil, although this organism can be readily isolated from the undecomposed residues of the Chinese cabbage in the field, if there is any. The soft rot of the Chinese cabbage in cellar develops throughout the storage period. |
