一、症状特点芦笋茎腐病主要危害幼笋。幼笋出土后即可能受侵害,幼茎出现水渍状不定形病斑,绕茎扩展,致茎组织崩解、腐烂,终致幼笋枯死。发病轻的即使不枯死,其生长势大减,地上部茎叶衰弱,幼茎细弱,产量低。二、发病特点灌溉水、雨水是病菌主要传播途径,其次病菌可借助施用土杂肥传播。连绵阴雨多的年份或季节有利于发病。低洼潮湿地、土质黏重地多发病。品种间抗病性情况尚
First, the symptoms of asparagus stalk rot harm the main shoots. Young shoots may be infested after the excavated, young stems appear water stain like shaped lesion, around the stem expansion, causing stem tissue disintegration, decay, and eventually death of young shoots. The incidence of light, even if not dead, its growth potential greatly reduced, aboveground leaves weak, young stems weak, low yield. Second, the incidence characteristics of irrigation water, rain is the main route of transmission of germs, followed by the use of bacteria can spread soil Tufei. More rainy years or season is conducive to the incidence. Low-lying wetlands, soil thick-stick disease frequently. Disease resistance among varieties is still
