Beneficial bacterium composition, microbial fertilizer containing beneficial bacterium composition and preparation method of microbial fertilizer

The invention discloses a beneficial bacterium composition, a microbial fertilizer containing the beneficial bacterium composition and a preparation method of the microbial fertilizer. The beneficial bacterium composition is prepared from paecilomyces lilacinus PM0327-3, bacillus licheniformis BL-1106 and bacillus subtilis BS-56, and the beneficial bacterium composition is prepared from the following components: bacillus licheniformis PM0327-3, bacillus licheniformis BL-1106 and bacillus subtilis BS-56. The three beneficial bacteria are obtained through selective pressure tolerance screening, have good resistance to self metabolite antagonism and resistance to antagonism of other two mixed flora metabolite, have good high temperature resistance, acid resistance and alkali resistance, are good in activity and stability, and are more beneficial to preservation, and the shelf life is prolonged. 本发明公开了一种有益菌组合物、含其的微生物肥料及其制备方法。所述有益菌组合物包括淡紫拟青霉菌(Paecilomyces lilacinus)PM0327-3、地衣芽孢杆菌(Bacillus licheniformis)BL-1106和枯草
