Problems solved by technology

However, the utilization rate of waste straw as feed is very low at present. The main reasons are that the cellulose content in the straw is high, and it is directly fed to livestock, which cannot be digested and absorbed by the livestock; And it is perishable and deteriorates, seriously affecting the quality of feed

Embodiment 1

[0076] (1) pulverize 0.75kg of forage beet to 1-2cm pieces, beat again until the sugar beet particle is less than or equal to 1cm to obtain a beet slurry, add 0.625g of compound bacterial agent, and mix to obtain a starter;

[0077] (2) Take 4.25kg of corn stalk, crush and knead it to 1.5-2cm, add the starter prepared in step (1), and after mixing, fill it into a 10L fermentation tank, adjust the moisture content to 65%, and maximize the Press down, seal the lid with tape, store it in the dark at room temperature (15-25° C.), and ferment for 50 days to obtain yellow stock feed.

Embodiment 2

[0079] (1) pulverize 1.5kg of feed beet to 1-2cm pieces, beat again until the sugar beet particle is less than or equal to 1cm to obtain a beet slurry, add 0.625g of compound bacterial agent, and mix to obtain a starter;

[0080] (2) Take 3.5kg of corn stalk, crush and knead it to 1.5-2cm, add the starter prepared in step (1), and after mixing, fill it into a 10L fermentation tank, adjust the moisture content to 65%, and maximize the Press down, seal the lid with tape, store it in the dark at room temperature (15-25° C.), and ferment for 50 days to obtain yellow stock feed.

Embodiment 3

[0082] (1) pulverize 2.25kg of feed sugar beet to 1-2cm pieces, then beat until the sugar beet particle is less than or equal to 1cm to obtain a sugar beet slurry, add 0.625g of compound bacterial agent, and mix to obtain a starter;

[0083] (2) Take 2.75kg of corn stalk, crush and knead it to 1.5-2cm, add the starter prepared in step (1), and after mixing, fill it into a 10L fermentation tank, adjust the moisture content to 65%, and maximize the Press down, seal the lid with tape, store it in the dark at room temperature (15-25° C.), and ferment for 50 days to obtain yellow stock feed.

Abstract

The invention relates to a straw resourceful treatment method which specifically comprises the following steps: (1) crushing feed beet, pulping into slurry, adding a complex microbial inoculant, and uniformly mixing to obtain a leavening agent; (2) adding the leavening agent into the straw, sealing at 10-30 DEG C, and fermenting in a dark place for 30-60 days to prepare the yellow corn silage feed, the complex microbial inoculant is prepared by mixing candida utilis, enterococcus faecium, bacillus subtilis and lactobacillus acidophilus according to the weight ratio of (1-5): (0.5-5): (1-5): 1. The yellow corn silage feed prepared by the invention is low in pH value and high in lactic acid and acetic acid content, inhibits the growth of harmful bacteria and the generation of harmful substances such as propionic acid and butyric acid in fermentation, solves the problem that the feed is easy to rot and deteriorate, is high in crude protein and fat content and low in cellulose content, is beneficial to eating and digestion of cattle and sheep, is used for feeding cattle and sheep, and has good economic benefits. The feed can significantly improve milk yield and milk quality of cattle and sheep, and is long in storage time and not easy to deteriorate.

Description

technical field [0001] The invention belongs to the solid waste in the field of environmental protection, and in particular relates to a method for recycling waste straw and its application. Background technique [0002] Straw is a general term for the stem and leaf (ear) parts of mature crops. Usually refers to the remainder of wheat, rice, corn, potatoes, rape, cotton, sugar cane and other crops (usually coarse grains) after the seeds are harvested. Gansu Province produces 25 million tons of straw each year, and about 50% of various crop straws are used as fuel, or are directly turned into the soil and returned to the field, which not only wastes resources but also seriously pollutes the environment. The Law of the People's Republic of China on the Prevention and Control of Air Pollution and the Regulations on the Prevention and Control of Air Pollution in Gansu Province clearly prohibit the burning of straw, and governments at all levels have also issued relevant policie...
