摘　　要：调查发现，从长白山引种至辽宁省栽培的高山红景天根茎腐烂十分严重，蔓延迅速．１～２年生植株发病率为３０％～４０％，３～４年生植株死亡率高达８０％～９０％。由发病区采集典型病株，在病健交界处取样，以组织分离法分离纯化，鉴定为高山红景天根腐病，属尖镰孢菌（ＦｕｓａｒｉｕｍｏｘｙｓｐｏｒｕｍＳｃｈｌｏｏｈｔ）引起。根据室内抑菌试验结果，进行田间药剂试验。试验结果表明，使用杀菌剂进行防治高山红景天根腐病，可以抑制极腐病的发展，有减轻根腐病的作用。Changbai mountain's Rhodiola Sachalinenesis A. Bor. has been introduced to be cultivated in Liaoning Province for several years. The findings show that the root and stem of the plant decayed and rotted seriously and this disease spread rapidly. The incidence of the disease was 30%￣ 40% for the 1￣2 year old plants and the death rate 80%￣90% for the 3￣ 4 year old plantd.The results of the experiment indicated that this root-rot disease caused by Fusarium oxysporum Schleeht could be controlled with many pesticirdes.
