| 摘 要： | 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。

Experiment on the Prevention and Control of the Damping-off of Nursery Stock of Parakmeria yunnanensis |
| |
| Abstract: | With the intention to improve the situation of the damping off of nursery stock of Parakmeria yunnanensis in the Nursery of Young Plants of the Yunnan Forest Narual Center and the Nursery of Young Plants of Yunnan Forestry School, two comparative experiments have been conducted :1) an experiment of using the uncultivated land to grow saplings and using the cultivated land in the nursery of young plants to do the same thing; 2)an experiment of alternately using the liquid which is 1000 times of 50% of Carbendazim and the liquid which is 200 times of 05∶1 of Bordeaux to prevent and control the damping off of the nursery stock and using other chemicals for the same purpose The experiments show that the use of the uncultivated land to grow saplings and the alternate use of the liquid which is 1000 times of 50%of Carbendazim and the liquid which is 200 times of 05:1 of Bordeaux to prevent and control the damping off of the nursery stock can achieve a satisfactory result for the prevention and control of the damping off of the nursery stcok. The incidence of disease is reduced to 18% and the death rate to 8% |
