细菌的个体非常小,要在装有油镜的显微镜下才能看见其形态。但是,它繁殖速度快,在适宜的环境条件下,每隔20～30分钟就可繁殖一代。因此在生产中要及时发现,及时处理,防止细菌病害的扩展蔓延。目前已知的细菌病害有:水稻白叶枯病,玉米茎腐病,棉花角斑病,马铃薯环腐病及白菜软腐病等。这些植物病原细菌,均在植物组织内繁殖和蔓延,引起植物细胞和组织的内部病变,从而表现为各种症状。其主要症状类型有:腐烂、坏死、肿瘤和萎蔫等。
The bacteria are so small that they can be seen under a microscope equipped with an oil mirror. However, it reproduces fast and reproduces every 20 to 30 minutes under suitable environmental conditions. Therefore, in the production should be promptly found, timely treatment to prevent the spread of bacterial disease spread. Currently known bacterial diseases are: bacterial blight rice, corn stalk rot, cotton angular leaf spot, potato ring rot and cabbage soft rot and so on. These plant pathogenic bacteria, both propagate and spread within plant tissues, cause internal lesions in plant cells and tissues and thus manifest as various symptoms. The main symptoms are: decay, necrosis, cancer and wilting.
