峡江县新陂林场1975年营造的500亩湿地松母树林,松针褐斑病发生严重。据1984年调查,株发病率为45—34.2%,病情指数为17.1—30.2,林内病枝枯叶随处可见,不少重病株已经死亡;病害严重地抑制了树木的生长。从1984年始我们采取了以清除病原为主要目的的综合防治方法,减少病原,改善环境条件,增强林木本身的自御能力。主要措施是,砍除林内枯死株、重病株并修除病枝叶,就地烧毁;清除杂灌,促使林内通风
Xiajiang Forest Farm in Xiajiang County in 1975 to create 500 acres of wetland pine woods, pine needles brown spot serious. According to the 1984 survey, the incidence of strains was 45-34.2% and the disease index was 17.1-30.2. The diseased leaves in the forest were everywhere and many seriously ill plants died. The diseases seriously inhibited the growth of the trees. Since 1984, we have taken a comprehensive prevention and treatment approach with the main purpose of clearing pathogens, reducing the pathogen, improving the environmental conditions and enhancing the self-protection capacity of trees themselves. The main measure is to cut down the dead wood in the forest, seriously ill strains and repair diseased branches and leaves, burned on the spot; remove miscellaneous irrigation, to promote ventilation in the forest
