芹菜根腐类病害是芹菜多种根部腐烂性病害的统称,其共同特点是芹菜植株在发病后根系发生腐烂,根功能逐渐丧失,引起地上部叶枝出现黄化、萎蔫、坏死等问题,造成芹菜产量和质量的严重损失。芹菜根腐类病害病因多样,病症表现相似又各有特点...芹菜根腐类病害是芹菜多种根部腐烂性病害的统称,其共同特点是芹菜植株在发病后根系发生腐烂,根功能逐渐丧失,引起地上部叶枝出现黄化、萎蔫、坏死等问题,造成芹菜产量和质量的严重损失。芹菜根腐类病害病因多样,病症表现相似又各有特点,有时还会出现并发现象,容易使人们在病害识别和病因判断过程中出现重大偏差,导致随后的防治工作走入歧途。本文以国内外相关文献为依据,结合自身工作经验,针对我国芹菜生产发生较为普遍的9种根腐类病害各自的症状特点、病原菌或病因以及发病规律进行梳理总结,为芹菜根腐类病害的识别与精准防控提供理论依据和技术参考。Celery root rot disease is a collective term for various related root rot diseases of celery. Its common feature is that after the disease occurs, the root system of celery plants decays, gradually losing root function, causing yellowing, wilting, and necrosis of stalks, resulting in serious losses in celery yield and quality. The causes of celery root rot diseases are diverse, and the symptoms are similar, but each has its own characteristics. Sometimes, concurrent phenomena may occur, which can easily lead to significant deviations in disease identification and judgment, leading to subsequent prevention and control work going astray. Based on numerous literature and combined with our work experience, this article summarizes the symptom characteristics, pathogens or causes, and pathogenesis of 9 common root rot diseases in celery production in China. It provides a theoretical basis and technical reference for the accurate identification and control of celery root rot diseases.展开更多
