| 摘 要： | 从菜地土壤中分离获得的拮抗细菌B-77经鉴定为枯草芽孢杆菌(Bacillussubtilis),用该菌株发酵液浸种能有效地防治由Fusariummoniliforme引起的水稻恶苗病。在盆栽条件下,B-77发酵液稀释10～100倍的防效达76.76%～78.53%;小区试验中,其10～100倍的防效亦达72.56%～76.18%,均与对照药剂25%先安乳油4500倍的防效无显著差异。B-77对水稻种子发芽及根茎生长无抑制作用。

Identification of Antagonistic Bacterial Strain B- 77 and Its Control Effect against Rice Bakanae |
| |
| Abstract: | Antagonistic bacterial strain B-77 was isolated from vegetable soil, and was identified as Bacillus subtilis.Soaking rice seeds in the fermented solution of B-77 could effectively control rice bakanae caused by Fusarium moniliforme. Results of pot culture and plot tests showed that the control effect of B-77(10～100 times fermented solution) reached to 72.56%～78.53%, and was not significantly different from that of the check(25% Xian'an 4500 times). In addition, B-77 didn't inhibit seed germination and seedling growth of rice. |
