Abstract: In order to grope for the feasibility of Banana cauloid silage, the effects of additives on cut and dried banana cauloid(DM≈25%),which make silage with formic acid, Ecological Microoganisms(EM), lactobacillus (LAB), EM and LAB.The results show that all the additive treatments could prove the fermentation quality further more; The pH、NH3-N and the ADF content of all the treatment significant better than the control group (p<0.05);The EM and LAB treatment was the best in all the treatments and it’s pH close to 3.9, the content of ADF decreased by 7.86%.The treatments add EM that is the second had no significant difference compare to the best .
