| 摘 要： | 对7种不同栽培处理的薯蓣根际土壤微生物进行分离及检测结果显示：锯末和稻秆基质穴栽的薯蓣根际土壤中薯蓣枯萎病菌（Fusarium oxysporum）拮抗微生物的数量分别为3.10×103CFU/g与4.30×105CFU/g,添加黄泥穴栽处理区、常规处理区及锯末、稻秆或黄泥添加辛硫磷的处理区均未检测到拮抗菌.实验结果表明,有机物的添加,有助于拮抗微生物的生长繁殖及土传病害,辛硫磷对根际拮抗微生物有抑制作用. |

| Abstract: | Isolation and analysis of rhizospheric microbes from the attachments on yam tubes with seven different cultivated treatments were carried out.The results showed that in the treatments of sawdustor rice straw-amended hole cultivations,the numbers of the rhizospheric microbes with antagonistic activity against Fusarium oxysporum causing yam wilt were 3.10×103 CFU/g and 4.30×105 CFU/g,respectively.No antagonists were detected in the treatments of the yellow mud-amended hole cultivation,traditional cultivation and sawdust,rice straw or yellow mud puls phoxim cultivation.The investigation indicated that the addition of organic substance in hole cultivation of yam was propitious for survival and reproduction of antagonistic microbes in the rhizospheric soil of yam,and for suppression of soilborne diseases.The application of phoxim had a suppressive effect on development of the antagonist populations. |
| Keywords: | Dioscorea oppsita soilborne disease cultivation substrate rhizospheric microbe biodiversity |
