| 摘要: |
| "桂植捕线菌七号"(CN.7),属烛台霉属(Candelabrella sp.),是一个具有捕捉环的肉食真菌,没有专化性.特点有三:1)对土壤线虫具有稳定的捕捉势和较强的捕食能力;捕食线虫的相对效果达70%以上,对寄主植物根系的保护效果更佳。2)能产生抗菌素,对植物的某些病害有兼防效果,其中对烟草青枯病(Pseudomonas solanacearum)防效达60%左右。3)对寄主植物有促进生长、改良品质的效果,其中对烟草至少可增产10%以上,烟叶的等级也有所提高。 |

| Abstract: |
| Gui-Zhi-CN.7(CN.7) belonging to Candelabrella sp.is a carnivorous fungus with a constricting ring,and has no speciality in capturing nematodes.The capture-ability to soil nematodes is stronger and stable,and the capture-effect is over 70%,bisides,the protection to host plant roots is better.CN.7can produce antibiotic,and prevent and cure the other plant diseases that not caused by nematodes.The preventive efficacy in tobacco wilt disease(Pseudomonas solanaceatum) is around 60%.CN.7 can stimulate growth of host plants and improve the quatity of crop,in which the output of tobacco was increased by over 10%,while the grade of tobacco was increased also. |
