| 摘 要： | 为了明确三江平原地区大豆根腐病发生的严重程度，于2014年对该地区所属县、市及农场内大豆进行病害调查，计算发病率及病情指数。采集大豆根腐病样本，对病株样本进行真菌的分离及鉴定，共分离获得相关致病真菌3个属10个种。镰孢菌为优势菌群，其分离频率为29.92%。镰孢菌中，尖孢镰孢菌为优势种，其占分离镰孢菌总量的65.75%。调查结果表明，含水量大及重茬地块，大豆根腐病发病率及病情指数较高。

| Abstract: | In order to confirm the severity of soybean root rot in Sanjiang Plain area, investigation of soybean root rot at the cities and farms belonging to Sanjiang Plain was carried out in 2014, incidence and disease index were calculated. Samples of soybean root rot were collected at the same time. After fungal isolation and culture, 10 species belonging to 3 genera connected with soybean root rot were identified. The predominant genus was Fusarium with isolation rate for 29.92%. The predominant species of Fusarium was F. oxysporum with isolation rate of 65.75%. Investigation results showed that incidence and disease index of soybean root rot were higher in block with high water content and continuous cropping. |
