2. Make straw into straw curtain, straw mat, straw mat, straw rope, straw blanket and other products.
3. Used for processing saccharified pig feed, silage and straw biological feed.
4. Used to brew five grains of wine.
5. Making biological pulp.
6. Produce biogas as raw material for biogas digesters.
Processing method of straw biological feed with extended data;
1, pretreatment: crushing, the function of crushing is to increase the specific surface area of rice straw, which is beneficial to the dissolution of anti-nutritional factors lignin and silicon dioxide, and at the same time, it is beneficial to the penetration of microbial hyphae and improve the efficiency of enzymatic hydrolysis. Harvesters are widely used in rural areas, and the harvested straw itself is crushed, which can be used locally and directly enter the next operation.
2. Dilute acid treatment, that is, adding inorganic acid, is cheap and less corrosive to equipment. 2%-5% inorganic ammonia is sterilized at high temperature to remove part of lignin and provide nitrogen source for microorganisms.
3. Add inorganic salts, inoculate strains to ferment calcium-magnesium ion rice straw, only need to add 1% inorganic phosphorus, then inoculate microorganisms and cultivate them in greenhouse or solid fermentor.
Screening of fermentation strains for straw bio-feed;
The initial research was single-strain fermentation, and later it was found that mixed bacteria had better effect. Functionally, it should include cellulose and hemicellulose decomposing bacteria, such as Bacillus subtilis, Trichoderma, Aspergillus niger, Rhizopus, Pleurotus ostreatus and Lentinus edodes. Secondly, it should include nutritionally fortified bacteria, such as yeast, to provide amino acid content and vitamins. These strains can be purchased from the strain collection centers of universities and research institutes, or they can be isolated from nature by themselves.
