| 摘 要： | 对滇朴干基腐朽病的调查、室内保湿培养、分离鉴定结果表明：引起滇朴干基腐朽的病原为伏革菌科隔孢伏革菌属的乳白隔孢伏革菌。该病害的发生随温度的升高、树龄的增长、降水的减少而逐渐严重,在土壤瘠薄、保水能力差的区域内发病严重。药剂防治80d后,用急救回生丹：金雷：水=1：1：50树干注射、包干的相对防效达86％;枝、干、叶喷70％甲基托布津＋杀毒矾700倍液的相对防效为79％;根部浇灌58％的雷多米尔＋杀毒矾800倍液的相对防效为81％。

| Abstract: | It was determined by the field survey,indoor moisture culture,isolation and identification that the pathogen of wood rot blight in Celtis kunmingensis was Peniophora cremea.The occurrence of the wood rot blight disease was related to the climatic conditions,which occurred severely when the trees grew in the poor,impact soil conditions with poor water retention capacity,while the soil drought developed,the air temperature rose,and the tree age increased.80 d after application,the control effect reached 86% b... |
