| 摘 要： | 板栗干枯病若在豫南地区由点及面的蔓延、发展开来，势必将会使豫南１２万公顷的板栗树全部毁灭，且同时造成豫南严重的水土流失和生态环境的恶化；我们详细调查了此病在豫南地区板栗园中的不同发生情况，并提出了严格检疫消毒苗木、改良土壤增强树势、降低密植度、加强清园工作、重视冬季树体保护、控制早春板栗园内温差及时刮去病疤六项预防措施。

| Abstract: | Recent investigations have shown that all the chestnuts will die out ,120.000 hectares in South Henan,if Endothia Parasitica is out of control for a short period,deadfull soil erosion and deterioration of ecological environment will be caused,too.Based on detailed investigations in diferent orchards,we got some characteristics about the disease and suggest 6 steps to deal with it,i.e.strict test and disinfection of seedlings ,grouth strenghening through reforming soil,lowering density of planting,reinforcing orchard clean,preservation trees in winter,clearing away the infected barks. |
