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.

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。

A root rot disease of jute caused by Papulospora sp. hitherto not reported from this country was found to distribute in areas along both sides of Chientang River. During the years 1954 to 1959, 14.7 to 24.6 percents of the plants were attacked. The first symptom was the browning of roots and the basal part of stem. In the later stage of infection the conducting system of stem was also affected. The stem was broken and the plant withered in severe conditions. In late August, black sclerotial bodies appeared...

1.黄麻根腐病为黄麻新的问题,目前了解的主要分布地区为浙江省沿钱塘江两岸的肖山、杭州市郊、原杭县等麻区。1954—1957年各地黄麻圆果种的平均发病率在14.7—24.6%以上。2.本病为害黄麻根及莖基等部分,使形成褐腐。病部不收缩,或微现收缩。后期病菌侵入输导组织,木质部形成黄褐色。8月下旬后,在病部出现大小约0.63×0.36毫米扁平不整形的黑色菌核,为本病的重要标志。3.本病以为害黄麻成株期为主。从6月下旬开始渐次出现病株,高峯期为8月下旬至9月下旬。在沙壤土中,地温(5厘米)平均在28—30℃,每旬降雨量在70毫米左右可以诱致严重发病。在一定温度下,雨量多少关系于发病程度极重要。4.经接种证实,本病为真菌Papulospora sp.所致,在病组织及普通培养基上不见分生孢子。生长发育以25—30℃为最适。矿物营养在缺碳时生长最差,缺氮时生长无大影响,迅速形成大量菌核;如加入蛋白腖,菌丝不复变色(白色),菌核不能形成。钾及磷对病菌生长发育的影响仅次于碳。5.含粘粒在10%以下的轻松土壤为最有利的发病环境。连作或轮作,对发病关系极为明显,多年连作地发病率较多年轮作或2—4年轮作地高7—53倍。6.笨麻主要...

油茶软腐病近年来越趋严重,经我们试验鉴定,当年病斑上表皮组织下产生的球形分生孢子座是真正的分生孢子座,无短柄。而病斑上表生的、具短柄的分生孢子座、形状较多,具菌核特性。分生孢子梗及分生孢子的形态是最稳定的,与漆斑菌属(Myrothecium)基本相同,故将油茶伞座孢(Agaricodochium camelliae)移名为油茶漆斑菌(Myrotheciumcamelliae(Liu,Wei et Fan)P.K.Chi,wu et Lin n.comb.)。
