Cassava straw silage and preparation method thereof

The invention discloses cassava straw silage and a preparation method thereof. The silage is prepared from, by weight, 150-200 parts of cassava straw, 30-35 parts of sunflower stems and leaves, 10-20 parts of sweet potato vine, 30-40 parts of corn straw, 30-50 parts of banana leaves and 10-15 parts of sticktight, and straw leavening agents are added according to the proportion of 11g/kg of the total mass of the mentioned raw materials. According to the cassava straw silage and the preparation method thereof, the cassava straw serves as the main raw material, the sunflower stems and leaves, the sweet potato vine, the corn straw, the banana leaves and the sticktight serve as auxiliary materials, the straw leavening agents are used for fermenting the raw materials, and a great amount of microorganism mycoprotein and beneficial metabolite are generated and accumulated. What's more important, the effect of microorganism culture in the straw leavening agents is utilized, cellulose and lignin in the cassava straw and the corn straw are degraded, meanwhile, the sweet potato vine, the banana leaves and the sunflower stems and leaves are added, all the constituents work together to improve palatability of the cassava straw, improve digestibility and enrich nutrient compositions of the silage, and the silage can be stored for a long time without mildewing or rotting.
