| 中文摘要: |
| 本文利用引进的放射土壤杆菌K84菌株对我国果树根癌病进行了防治效果的研究，主要包括室内、温室和田间抑菌效果的检验、生产用培养基的改进和菌剂剂型的选择等。室内和温室试验表明，K84菌株能够抑制所有供试的生物Ⅱ型和部分生物Ⅰ型的根癌土壤杆菌，而对来自葡萄的Ⅲ型病菌无效。桃树的田间试验表明K84菌株对人工接种的病菌预防效果可达100％，对自然重茬土壤内的根癌菌也有明显的防治效果，苗龄越小、处理越早，防治效果越好。草炭制剂明显优于液体制剂，其保存期长而且易于运输。本文还介绍一种适于大规模生产的培养基WY。 |
| 英文摘要: |
| Crown gall disease control of fruit trees with Agrobacterium rediobacter K84 was studied inChina.It included the efficiency of the strain under laboratory,greenhouse,and field conditions.The ap-plicable media and formulations were also investigated.Tests in laboratory and greenhouse indicated thatstrain K84 inhibited all tested pathogenic strains of biotype Ⅱ and part of biotype I.Strains of biotypeⅢ from grapevines were not sensitive.Field trials showed that strain K84 protected peach trees fromcrown gall caused by artificial inoculations.Field tests in naturally infested soil also revealed obvious effi-ciency.The younger the plants,and the earlier the treatment,the better the results.Peat formulation wasbetter than the liquid one,the former was easier to be preserved and transported.WY medium was appli-cable to industrial production of the bioagent. |
