The invention belongs to the field of
feed processing, and particularly relates to a sweet potato
seedling and corn
straw mixed
silage preparation method which comprises the following steps: S1,
raw material pretreatment: respectively chopping sweet potato seedlings and corn straws; s2, mixing: the chopped sweet potato seedlings and corn straws are weighed, an additive is added, the mixture is uniformly mixed, the additive is a mixed
lactic acid bacteria additive, and the addition amount is 0.1 g / kg; s3, loading into a
silage container, compacting and sealing; s4, storage: the
fermentation temperature range is 15-28 DEG C, preferably 25 + / -1 DEG C. According to comprehensive evaluation, the sweet potato seedlings and the corn
straw are mixed and ensiled according to the proportion of 1: 1, and the comprehensive value is the highest. The proportion can effectively balance dry substances and
moisture of the two raw materials, and the
silage which is excellent in smell, color and texture, complete in
nutrition preservation and excellent in
fermentation quality can be obtained after the mixed
lactic acid bacteria additive is added for ensiling for 60 days.
