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.

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. It is therefore convinced that the-primary source of infection of the soft rot of the Chinese cabbage is either from the undecomposed residues from the field or from the debris in the cabbage cellar. The seed Chinese cabbage from the cellar after overwintering is planted out at the end of march and meanwhile carries the soft rot organisms to the field. Furthermore, a number of insects serves as spreaders. Isolations of a number of insects found either in cabbage cellar or in spring cabbage fields reveal that 76% of Sarcophaga sp., 66.8% of Fannia sp., 4% of Apis mellifera, 40% of Athalia rosae and 30% of Plutella maculipennis are found to carry soft-rot organisms both externally and internally. The results of an field experiment point out that the early diseased cabbage plants in the field serve as centers of infection of the soft-rot disease. The bacteria are disseminated in the field by the irrigation water. However, only those cabbage plants which are wounded at the basal part are liable to the attack. It is therefore suggested that in addition to the control of insect pests in connection with the adequate cultural practice, the thoroughness of eliminating the centers of infection by prompt removal of the diseased plants from the field every time before irrigation must be observed. In the present paper a rapid method for determining the pathogenic soft-rot bacteria from the soil is described.

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?杭居陕橛?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。菜畦內发生的早期病株是軟腐細菌的供給者。凡是畦內菜株受伤而有早期病株时全畦发病最重;畦內菜株无伤而无早期病株时发病最輕。在菜株受伤的情况下,早期病株的影响特别显著。灌溉水有在畦內传布病原細菌的能力。建議在防治中結合栽培及防虫必須注意在每次灌水前及早拔除早期病株,以增进防治的效果。
