Embodiment 1

[0021] Select the sweet sorghum that has been eared, and harvest it from the ground 8-12cm on a sunny day. The cut sweet sorghum is spread on the spot in the sun for 3 hours and then bundled to reduce the moisture content to 68%. The baled sweet sorghum is transported back as the silage raw material, and the silage raw material is immediately cut into short lengths of 1 cm with a silage chopper. Put the chopped silage raw materials into a plastic bucket with a volume of 20L, fill the silage raw materials layer by layer, the thickness of each layer is 10cm, and spray the prepared lactic acid bacteria fermenting yeast liquid at the same time (from clear water, accounting for clear water 2-3% brown sugar and 0.01% urea in water, at room temperature 23℃~28℃, press 10 8 cfu / L solution inoculated with lactic acid bacteria, fermented and cultured for 4-7 days, and the pH value was reduced to 3.8-4.0) and then tamped with wooden sticks, and 2ml of fermented yeast solution was used fo...

Embodiment 2

[0023] Select the sweet sorghum that has been eared, and harvest it from the ground 8-12cm on a sunny day. The cut sweet sorghum is spread out on the spot for 2 hours and then bundled to reduce the moisture content to 70%. The baled sweet sorghum is transported back as the silage raw material, and the silage raw material is immediately cut into short lengths of 1.5 cm with a silage chopper. Put the chopped silage raw materials into a plastic bucket with a volume of 20L, fill the silage raw materials layer by layer, the thickness of each layer is 15cm, and at the same time spray the prepared lactic acid bacteria fermenting yeast liquid (from clear water, account for clear water 2-3% brown sugar and 0.01% urea in water, at room temperature 23℃~28℃, press 10 8 cfu / L solution inoculated with lactic acid bacteria, fermented and cultured for 4-7 days, and the pH value was reduced to 3.8-4.0) and then tamped with wooden sticks, and 2ml of fermented yeast solution was used for every ...

Embodiment 3

[0025] Select the sweet sorghum that has been eared, and harvest it from the ground 8-12cm on a sunny day. The cut sweet sorghum is spread out on the spot and dried for 1 hour and then bundled to reduce the moisture content to 75%. The bundled sweet sorghum is transported back as the silage raw material, and the silage raw material is immediately cut into short lengths by 2 cm with a silage chopper. Put the chopped silage raw materials into a plastic bucket with a volume of 20L, fill the silage raw materials layer by layer, the thickness of each layer is 25cm, and spray the prepared lactic acid bacteria fermenting yeast liquid at the same time (from clear water, account for clear water 2-3% brown sugar and 0.01% urea in water, at room temperature 23℃~28℃, press 10 8 cfu / L solution inoculated with lactic acid bacteria, fermented and cultured for 4-7 days, and the pH value was reduced to 3.8-4.0) and then tamped with wooden sticks, and 2ml of fermented yeast solution was used f...

Abstract

The invention relates to the biotechnology processing field, and especially relates to a method for preparing silage by using sweet sorghum, and the method comprises the following steps: harvesting, cutting into short part, filling, sealing, performing silage management. In the filling step, a lactobacillus fermentation mother liquor is sprayed on a cut silage raw material. The method is characterized in that sweet sorghum at a heading period is harvested at sunny day, and dried for 1-3 hours, the moisture of sweet sorghum is kept between 68-76%, cutting is carried out according to 1-2cm length, filling and compressing are carried out layer by layer, in the filling process, a spraying method of the lactobacillus fermentation mother liquor is used for making up the disadvantages of insufficient lactobacillus of the plants, the silage is capable of rapidly forming lactobacillus for fermentation during the production process, and thereby the silage with high quality can be produced, the color of the silage presents yellow and green, the sour fragrance is obvious, and nutrient loss can kept less than 8%.

Description

technical field [0001] The invention relates to the field of biotechnology processing, in particular to a method for preparing silage from sweet sorghum. Background technique [0002] Silage is the feed of livestock such as cattle and sheep prepared by using straw, grass and other fresh pastures through certain methods. It can not only be preserved for a long time, but also has rich nutrients. It is an important feed for herbivorous animals. It is also one of the main methods to solve the lack of fresh pasture in winter in animal husbandry production. Silage is produced by fermentation with lactic acid bacteria in an anaerobic environment. The principle is: in an anaerobic environment, lactic acid bacteria can multiply rapidly and in large quantities, converting starch and soluble sugar in green materials such as pasture and straw into lactic acid and accumulating to a certain concentration, reducing the pH value in the silage environment to below 4.2 , and then effectivel...
