在阿尔泰、奥尔洛夫浆果站等地的人工、天然沙棘林中,健康的沙棘植株多在栽植后的第2年7—8月突然干枯。有时在夏初个别植株顶部叶子变黄,然后落叶,有果实的枝条8—10天干枯。这个过程逐渐扩大到下面枝条,整个植株短期内就会死亡。在死亡植株根部下一年常萌发新枝条。萌发枝条3—4年后也常死亡。有时沙棘丛经过几年全部死亡,首先是单独枝条,而后就是整株死亡。树枝和树干受害后,在树皮上可形成众多小的橙黄色肿瘤突起和纵向黑色凹陷带。受害植株的休眠芽8月份可以萌发,并在橙黄色瘤突的地方形成淡绿色枝条。在根和枝条的横断面上受害初期有环状或点状木质部坏死。受害多由树枝的分权处开始,有时在
In artificial, natural seabuckthorn forests such as Altai and Orlov berry stations, healthy seabuckthorn plants suddenly dried up in July-August of the second year after planting. Sometimes in the early summer leaves of individual plants turn yellow, then deciduous, with fruit branches 8-10 days dry. This process gradually expanded to the following branches, the entire plant will die shortly. In the next year under the root of dead plants germination of new branches. Sprouting branches also often die after 3-4 years. Sometimes seabuckthorn plexus all died after a few years, the first is a separate branch, and then the whole plant died. Branches and trunk damage, the bark can form a large number of small orange-yellow tumor protrusions and longitudinal black hollow zone. The dormant buds of the affected plants can germinate in August and form light green branches in the areas of orange-yellow knobs. In the initial cross-section of the root and shoot damaged ring-shaped or punctate xylem necrosis. Victims often start from the branches of branches, sometimes in
