| 摘 要： | 数年的广泛调查结果表明, 板栗疫病在浙江发生普遍, 但危害轻度的地方多, 严重的地方少。危害稍重和严重的地方, 多半是由于管理差, 其他病虫弱枝多, 特别是板栗吉丁虫危害重等原因诱发的。接种观察的结果是无伤接菌的发病率为0 , 轻伤接种(削皮接)的发病率为20 %, 重伤接种(撬皮接)的发病率100 %, 1 a 之后, 发病株死亡率为33 %和80 %, 表明栗疫菌对无伤或轻伤的板栗枝干难以侵染, 对有较重伤口的板栗枝干则能造成较大危害。浙江杭州地区, 板栗疫病的过冬病斑, 2 月下旬即开始扩展, 4 ～ 6 月扩展较快, 7 月以后扩展缓慢。表2 参4

| Abstract: | An investigation conducted for several years shows that Cryphonectria parasitica is very popular in Zhejiang , with more lightly infected cases than heavily infected cases .Poor administration , more disease-or pestinfected shoots and weak shoots contribute to heavy infection .Particularly , heavy damage caused by Taxoscelus curieps can induce the infection of Cryphonectria parasitica .Investigations and observations suggest that for inoculation onto plants that are not wounded , lightly hurt (bark-cutting graft)plants and heavily hurt (bark-lifting graft)plants , the diseased rate is 0 , 20 % and 100 % respectively and the death rate is 33 % and 80 % respectively for diseased plants after one year , which shows that its difficult for Cryphonectria parasitica to infect unwounded or lightly hurt shoots but it does serious damage to heavily hurt shoots of Chinese chestnut .In the region of Hangzhou , Zhejiang , diseased spots that have wintered begin spreading in late February and spread fast from April to June , followed by a slow spread after July . |
