Problems solved by technology

At present, the research on how to rationally utilize straw mainly focuses on the following three aspects: ① Directly return straw to the field to increase soil fertility, but it is not good for current crops
② Using microorganisms to ferment crop straws to produce protein feed, but the application technology is not perfect
③Using straw to produce alcohol and methane, the economic benefits are uneconomical
[0006] 2. The waste of a large amount of straw is because no effective utilization technology has been invented
[0007] 3. A large amount of straw waste is not found a good way to use
[0008] 4. The main reason why straw is difficult to use
[0009] There are three main reasons for the waste of a large number of crop stalks. First, the harvesting time of crop stalks is too concentrated, and the manpower, equipment and methods of large-scale processing cannot meet the actual requirements, resulting in waste and waste.
Second, the crop straw is bulky, the transportation cost is high, and the flammability makes storage difficult, which affects the storage value of the straw and the possibility of long-distance transportation.
Third, straw utilization technology can not meet the needs of production

Embodiment 1

[0052] A preparation method of multifunctional crop straw peat:

[0053] Cotton, corn, wheat, rice and bean stalks are pulverized into 1-3 cm chunks, flakes, filaments and powdery stalks with a hammer mill; the wet and dry materials are Mix and put in the stacking tank; the mixing humidity of the material is about 35%; and immediately mix with the antiseptic additive; the amount of antiseptic: "Em" bacteria: urea: formaldehyde in a weight ratio of 1:0.5:2, wherein " Em" bacterial agent is: make mother liquor with 5 parts by weight of commodity " Em " bacterial agent, add molasses pure water (the ratio of molasses is 10-20% of pure water) mixed solution of 1.5 parts by weight, store in 25 ℃ of sealed environments 3 One day, get the enlarged "Em" application bacterial agent; the mixed bacterial agent is diluted with water in proportion (diluted to 10-15 times with water) preservative bacterial liquid, sprinkled on the surface of the material, and mixed with the material; the "Em...

Embodiment 2

[0057] A preparation method of multifunctional crop straw peat:

[0058] With embodiment 1, difference is:

[0059] The added "Em" bacterial agent: urea: formaldehyde is in a weight ratio of 1:0.5:1.5, and the ratio is diluted with water (diluted to 10-15 times), and sprinkled on the surface of the material;

[0060] When adding preservatives, the "Em" bacterial agent cannot be mixed with urea and formaldehyde, but urea can be mixed with formaldehyde. First use the "Em" bacterial agent, followed by urea, and finally formaldehyde.

[0061] The preparation of the secondary starter activated by the "Em" bacterial agent: when the repurchased commercial "Em" bacterial agent is used as the mother liquor for secondary simple fermentation expansion preparation, add 1.5 parts of brown sugar or syrup by weight, and then add 5 parts of "Em" commercial mother liquor, stirred evenly and stored at 30°C for 2 days, then it can become an activated secondary fermentation expanded "Em" bacteri...

Embodiment 3

[0064] A preparation method of multifunctional crop stalk peat, the same as embodiment 1, the difference is:

[0065] The added "Em" bacterial agent: urea: formaldehyde is in a weight ratio of 1:0.5:1.5, and the ratio is diluted with water (diluted to 10-15 times), and sprinkled on the surface of the material;

[0066] Use "Em" bacterial agent in turn, followed by urea, and finally formaldehyde mixture.

[0067] The preparation of the secondary starter activated by the "Em" bacterial agent: when the repurchased commercial "Em" bacterial agent is used as the mother liquor, and the secondary simple fermentation expansion preparation is carried out, 1 part of brown sugar or syrup is added in parts by weight, and then added 4 parts of "Em" commercial mother liquor, stirred evenly and stored in an environment of 25°C for 3 days, can become an activated secondary fermentation expanded "Em" bacterial agent.

Abstract

The invention discloses a multifunctional crop straw turf production and preparation method, which comprises the steps of mechanically grinding straws; treating with a preservative; mechanically rolling; and carrying out secondary fermentation and storage, so as to obtain multifunctionally utilized biological turf, wherein the preservative is one of 'Em' fungicide, urea and formaldehyde, or a combination of 'Em' fungicide, urea and formaldehyde. The invention also provides application of the turf prepared by using the preparation method of the multifunctional crop straw turf in the aspect of biomass recycle. The turf can be used as a biofertilizer, a biological feed, biological fuel, an edible fungi base stock, a biological fibreboard and an energy material. The multifunctional turf is wide in raw material resource and low in price; the preparation method is simple and convenient and low in cost, can achieve the purpose of attractive price and quality, and is a good method which is adopted by various regions; the big problem of straw utilization is solved, and a new economic way for rural development is initiated.

Description

technical field [0001] The invention relates to new biomass material resources, in particular to the preparation of a kind of biomass peat prepared from crop stalks, and in particular to the production of multifunctional peat from crop stalks and a preparation method thereof. Background technique [0002] All kinds of grasses and woody straws on the earth are the most abundant renewable energy sources in the world. According to incomplete statistics, the world's annual output of straw is about 2.9 billion tons. my country is a large agricultural country, with the largest area of ​​multiple cropping every year, and the annual output of straw ranks first in the world, reaching 700 million tons, accounting for about 25% of the world's total. [0003] As a biological resource, straw has a wide range of uses, such as: wheat straw, reed, etc. for papermaking; corn straw, beans, and potato straw for feed. Cotton stalks and grain stalks used in the board industry. As an energy so...
