    • The present invention relates to the antagonistic bacteria that are used to prevent and eliminate tobacco bacterial wilt and their microbial organic fertilizer, which belong to the technology for agricultural intensive production. The present invention separates two antagonistic bacteria (Brevibacillus brevis NJL-25 and Bacillus cereus NJL-14) that have remarkable antagonistic action against the pathogens of tobacco bacterial wilt. Microbial organic fertilizer is produced from these antagonistic bacteria and organic compost. Wherein, the content of each of NJL-25 and NJL-14 is above 1×1010 cfu/g, the content of total nitrogen is 4˜5% (above 90% of the nitrogen is organic nitrogen), the content of total nitrogen-phosphorus-kalium nutrient is 6˜10% and the content of organic matter is 30˜35%. As indicated by experiments, after the microbial organic fertilizer is applied into soil, it will enable rapid multiplication of the antagonistic bacteria into a dominant microflora in the soil and achieve more than 97.6% of biocontrol rate of tobacco bacterial wilt in the soil suffering from tobacco bacterial wilt. If the microbial organic fertilizer is applied in the soil without continuous cropping obstacle in a long time, it can prevent the occurrence of the bacterial wilt of continuous cropping tobacco to a great extent.
    • 本发明涉及用于预防和消除属于农业密集生产技术的烟草枯萎病及其微生物有机肥的拮抗菌。 本发明分离对烟草细菌枯萎病原体具有显着拮抗作用的两种拮抗菌(Brevibacillus brevis NJL-25和Bacillus cereus NJL-14)。 微生物有机肥由这些拮抗菌和有机堆肥生产。 其中,NJL-25和NJL-14的含量均在1×10 10 cfu / g以上,总氮含量为4〜5%(氮有机氮的90%以上),总氮含量 磷钾营养为6〜10%,有机质含量为30〜35%。 如实验所示,微生物有机肥施用于土壤后,能够使拮抗菌快速繁殖,成为土壤中的主要微生物群落,在烟草土壤中达到97.6%以上烟草枯萎病菌生物防治率 细菌枯萎。 如果微生物有机肥在土壤中长时间施用于连续作物的障碍物,可以在很大程度上防止连续作物烟草的枯萎病的发生。
