针对云南森林自然中心苗圃和云南林业学校苗圃在培育云南拟单性木兰苗时,苗木受猝倒病危害较为严重的特点,通过选用未耕作过的基质培育苗木与选用苗圃地基质培育苗木进行对比试验,用50%多菌灵可湿性粉剂1000倍液和0 5∶1的波尔多液200倍液交替使用防治苗木猝倒病与其它药物防治苗木猝倒病进行对比试验,通过试验发现前者对防治苗木猝倒病有较好防治效果,苗木发病率控制在18%,发病苗木死亡率控制在8%,在生产中应用成效显著。
According to the characteristics of nursery of Yunnan Forest Nature Center and Yunnan Forestry School nurturing Yunnan nudibranch, the seedlings were more severely damaging to damping-off disease. Compared with the nursery substrate selection nursery, Test, with 50% Carbendazim WP 1000 times and 0 5: 1 Bordeaux mixture of 200 times alternately used to control seedling damping-off disease and other drug control seedling damping-off disease comparative test, the test found that the former control Seedling damping-off disease has a better control effect, the incidence of seedling control in 18%, the incidence of seedling mortality control in 8%, the application of significant results in the production.
