| 摘 要： | 以前期研究筛选的、能在各向日葵主产区应用的1株生防菌株枯草芽孢杆菌S-16为试材,在盆栽条件下,检测了其在土壤中及植物体内与繁殖能力,并测定了菌株S-16的5种菌液处理液对向日葵菌核病的抑制效果。结果表明：在接菌7 d后土壤中和植物体内的菌量均达到103cfu/g以上,并且在接菌28 d内稳定定殖并大量繁殖;5种菌液处理中代谢液处理的综合防效最高,防效达73.33%。菌株S-16具有良好的应用潜力。 |
| 关 键 词： | 生物防治 向日葵菌核病 枯草芽孢杆菌 定殖 种子处理 |

| Abstract: | Bacillus subtilis S-16 came from College of Agronomy,Inner Mongolia Agricultural University,which had high antagonistic activity to Sclerotinia sclerotiorum.The colonization of S-16 in soil and plants was detected with pot culture.The inhibitory effects of five types of S-16 liquid on S.sclerotiorum was studied.The results showed that the amount of S-16 in soil and plant was above 103 cfu/g 7 days after inoculation.It had multiplied in 28 days after inoculation.The control effect of metabolic liquid of S-16 on S.sclerotiorum was 73.33%. |
