马铃薯加工厂的污水及其废料可能成为马铃薯癌肿病扩散的根源。马铃薯洗净加工后在沉淀池澄清水中有生命的病原菌的游动孢子囊的比重为1.3—1.4,它们随同土粒沉淀到池底。游动孢子囊一般要在50—30度的条件下经过5—40昼夜死掉,沉淀物除必需消毒外,并可用来做堆肥。但在20度以下温
Wastewater from potato processing plants and their waste may be the source of the spread of the disease in potatoes. After washing the potato, the zoosporangi of the living pathogens in the clarified water of the sedimentation tank has a specific gravity of 1.3-1.4, and they sediment together with the soil particles to the bottom of the pond. Zoosporangia generally 50-30 degrees after the death of 5-40 days and nights, in addition to the sediment required disinfection, and can be used to make compost. But below 20 degrees temperature
