微生物肥料菌种筛选及优化

Research on Screening and Optimization of Microbial Fertilizer Strains

植物根际促生菌是生活在植物根际土壤中,能够促进植物生长、防病害和增加作物产量的有益菌。由植物根际促生菌制成的微生物肥料,不仅经济、环保,还能大力推动绿色农业的发展。基于此,本实验通过对不同高效解磷菌株与解淀粉芽孢杆菌拮抗作用以及与玉米大斑病病原菌拮抗作用进行评价,筛选出制备微生物肥料的目标菌种,为微生物肥料的进一步研发和利用提供依据。

Plant rhizosphere growth promoting bacteria are beneficial bacteria that live in the rhizosphere soil of plants and can promote plant growth,prevent diseases,and increase crop yield.Microbial fertilizers made from plant rhizosphere promoting bacteria are economical and environmentally friendly,vigorously promoting the development of green agriculture.Based on this,this experiment evaluated the antagonistic effects of different high-efficiency phosphate solubilizing bacterial strains against Bacillus amyloliquefaciens and against the pathogen of corn leaf spot disease,and screened the target bacterial strains for preparing microbial fertilizers.It can provide a basis for further research and utilization of microbial fertilizers.
