摘要
从亚麻立枯病的发生、发展危害、病原菌分离、培养、鉴定到病害综合防治 ,进行了系统研究 ,明确了该病的发生与品种、土壤类型及气象因素等诸方面的关系 ,为病害防治提供了理论依据 ;也明确了带菌土壤和种子是该病害主要侵染源和传播途径 ,用药剂防治效果可达 80 %以上 ;
The paper is about the occurrence, development, harmness, separation of pathogenic bacteria, culture identification, and comprehensive prevention of flax rhizoctonia disease. The occurrence of the disease is related to flax varieties, types of soil and atomaspheric factors. These provide theorical basis for prevention of rhizoctonia disease. The study makes it explicit that soil and seeds with bacteria are the major resources of infection and spreading path. Flax rhizoctonia disease can be prevented by fungicide, the rate of prevention is more than 80% in a system of comprehensive prevention.
