【摘要】 通过微贮过程中微生物区系的变化，证实加入秸秆快速微贮生物添加剂可使微贮过程中有益菌数迅速增加，在８天内达到高峰值，并一直保持１０９个／ｇ以上。由于有益菌的优势地位抑制了腐败菌的生长，秸秆无霉变现象，从而证明这种复合菌剂在促进秸秆定向发酵中的作用更多还原

【Abstract】 The effective microorganisms increase up to 10 9 m/g after eight days when bio additive is used in the process of straw microbial silage. Also find that the effective microorganism is predominent and inhibit the growth of harmful bacteria by the obser vation of microorganisms variation. The straw doesnt rot either. It verified that the bio additive leads an important role in the process of staw microbial silage.更多还原
