湖北省农科所今年8月19—22日,在武昌召开了红苕贮藏病害研究座谈会。参加会议的有省、专及重点县有关部门、华中农学院和重点阈营农场等20个单位的代表26人。会议广泛交流了经验,肯定了成绩,明确了方向,落实了任务;并一致通过了三文件:(1)“有关红苕安全贮藏的建议”;(2)“红苕软腐病黑斑病示范试验计划;(3)“试验研究规划草案”。会议期间,还对以下几个问题进行了热烈的讨论: 一、红苕烂窖的主要原因:有人说,红苕烂窖的原因,病害是主要的。病害有两种,一为软腐病,一为黑斑病。软腐病的发生除与冻害有关外,红苕破伤是主要诱因;黑斑病主要由于大田发病,入窖苕块带病率高所引起的。“发汗期”的高温高湿,有利于黑斑病的发生,病菌繁殖加快,又从而促使窖温增高。如此互相影响,彼此促进,造成黑 Agricultural Science Institute of Hubei Province August 19-22 this year, held in Wuchang Symposium on storage disease research. Attending the meeting, there are 26 representatives of 20 units including provincial and special key county departments, Huazhong Agricultural College and key threshold camp farms. The meeting extensively exchanged experiences, affirmed the achievements, clarified the direction and implemented the tasks; and unanimously adopted the three documents: (1) “Suggestions on Safe Storage of Red Crab”; (2) “Red Cotyledon Rot Disease Test Plan; (3) ”experimental research draft plan.“ During the meeting, but also on the following issues were heated discussion: First, the main reason for red calamus: Some people say that the cause of red cellar rot disease is the main. There are two kinds of diseases, one for the soft rot, one for the black spot disease. In addition to the occurrence of soft rot disease and frostbite, red tuna is the main cause of injury; black spot disease mainly due to the field, High caused by the ”sweating period" of high temperature and humidity, is conducive to the occurrence of black spot disease, bacteria multiply faster, and thus to promote the cellar temperature so that each other, promote each other, resulting in black
