广东韶关地区农业局等单位认为,除个别年份气温降到致死低温时可以直接导致死秧外,在大多数年份,低温的影响主要是削弱秧苗的生活力和抗病力,这是烂秧的诱发因素。但秧苗死亡与否很大程度上取决于致病菌的作用,其中以绵腐病菌,立枯病菌,细菌性褐条病菌等较昔遍。
Shaoguan District of Guangdong Bureau of Agriculture and other units that, in addition to a few years the temperature dropped to lethal death can directly lead to dead seedlings, in most years, the impact of low temperature is mainly to weaken the viability of seedlings and disease resistance, which is rotten Inducing factors. However, the death of seedlings depends largely on the role of pathogenic bacteria, among them, Moraxella, Rhizoctonia solani, bacterial brown fungi and other more common.
