本文通过蚕豆根病田间调查和鉴定,分析了苗期和成株期发病的相关性。结果表明,苗期病原以尖孢镰刀菌为优势种,症状以基腐型为主。成株期病原以燕麦镰刀菌为优势种,症状以基腐萎蔫型为主。两期病情没有相关性。时间对病情影响不大。苗期病情并不能预测成株期病情;防治上宜用改善栽培条件为主的综合防治措施。 In this paper, Vicia faba root disease field investigation and identification, analysis of the correlation between seedling stage and adult incidence. The results showed that Fusarium oxysporum was the dominant species at the seedling stage, and the main symptoms were basal rot. The pathogen of adult plant was Fusarium of Oaty, the dominant symptom was basal wilting. No correlation between the two conditions. Time has little effect on the disease. Seedling disease does not predict the status of adult plants; prevention and control should be used to improve the cultivation conditions based comprehensive prevention and control measures.
