| 摘 要： | 为了探索安宁油菜根肿病的生物防治新模式,研究生防功能菌株对油菜根肿病的影响。通过生防功能菌株的直接施用、添加到有机肥或基质中施用的小区试验进行研究。试验结果表明：生防功能菌株能有效降低油菜根肿病的发生及危害,生防功能菌株直接施用对油菜根肿病的防效达74.03%,将菌株添加到有机肥中施用时防效达83.12%,将菌株添加到基质育苗时防效达68.83%,化学防治的防效达89.61%。将生防功能菌株添加到油菜秸秆腐熟发酵的有机肥中施用,对油菜根肿病的防效最佳,能促进油菜生长发育,并提高油菜的产量。相比常规施肥,株高提高7.63%,有效分枝数提高26.08%,产量提高16.81%。

| Abstract: | The aims are to explore the new biological control model of rape clubroot in Anning, and to study the effect of biocontrol strains on rape clubroot. The research is carried out through a plot test with direct application of the biocontrol functional strains, and adding the biocontrol functional strains to organic fertilizer or substrate application. The results showed that: the biocontrol functional strains could effectively reduce the occurrence and damage of rape clubroot. The control effect was 74.03% on rape clubroot when biocontrol functional strains were directly applied, 83.12% when the strains were added to organic fertilizer, 68.83% when the strains were added to substrate, and 89.61% when the chemical control was used. Adding biocontrol strains to organic fertilizer which was decomposed and fermented from rape straw could achieve the best control effect on rape clubroot, and promote the growth and development and the yield of rape. Compared with conventional fertilization, the plant height, the effective branch number and the yield were increased by 7.63%, 26.08% and 16.81%, respectively. |
