Abstract

The present invention relates to a preparation method of corn stalk microstorage feed. It is characterized by that said method includes four processes: (1), adding 2g of sugar into 25kg of water, after the sugar is dissolved, adding 3g of living dried inoculum, standing still for 1-2h at normal temperature to make the inoculum be revivified so as to obtain revivified inoculum; (2), adding the revivified inoculum agent into the fully-dissolved salt water (containing 8kg of salt and 800L of water) and uniformly stirring them; (3), laying 1000kg of cut com stalk on the cellar bottom, its thickness is about 20-25cm, uniformly spraying inoculum liquor, compacting, more laying stalk layer whose thickness is 20-25cm, more spraying inoculum liquor, compacting until the stalk layer is 40cm higher than cellar mouth, then uniformly spreading edible salt powder on most upper layer of stalk, compacting, laying plastic film and sealing, on the plastic film laying stalk layer whose thickness is 20-30cm, covering soil layer whose thickness is 15-20cm and sealing; and (4), taking out stalk sample, checking its water content, if its water content is 60%-65%, the optimum microstorage corn stalk feed can be obtained.

Description

The preparation method of the little storage of a kind of maize straw

Technical field

The present invention relates to the preparation method of the little storage of a kind of maize straw.

Background technology

Straw is made feed, is new technology, mainly is to reduce aquaculture cost, and it is low, effective to increase benefit stalk micro storage cost.The ox of breast-feeding is raised in little storage, and daily yielding can improve 10%-20%.Feed the mature beef daily gain and can improve about 20%, effect is better than ammoniated forage.Microbiological fermented feed contains rich in protein, vitamin, mineral matter and organic acid, and can digest the proportion of fibers height, easily chew, and can activate the stomach microorganism, the digestive utilization ratio height of straw, 3 kilograms of little storage straws of digestive utilization ratio that also can improve concentrated feed are equivalent to the nutritive value of 1 kilogram of corn.The straw of little storage has sour fragrance from hard to soft, can improve ox, sheep feed intake, and feed intake increases by 20%, and grazing speed improves more than 40%, and it is poor to have overcome ammonification straw palatability, causes shortcomings such as ammonia poisoning sometimes.Corn stalk is one of main roughage of ox.Several years facts have proved, with the corn stalk is raw material, the pellet that technology is made such as roll through pulverizing, mixing, high pressure, high temperature, good with its palatability nutrition, the grazing rate height, transportation stores characteristics such as convenient, not only is subjected to domestic raiser's welcome, and find a good sale in Japan, Korea S, its feeding value obtains approval more and more widely.

Played the variation of matter after straw is processed, at first protein content improves, and sex change can take place feed protein in pelletization, and the phthalein chain structure extends, the touch opportunity of increase and animal alimentary canal enzyme, the digestibility of raising protein.Straw particle after the processing can improve 2-3 percentage point than crude straw grass, protein content.Secondly the variation of matter all takes place in starch and fat, in pelletization its physical property will be from dissolving, swell to gelatinization a series of variations take place.Chemical reaction such as also be hydrolyzed is for the effect of feeding animals enzymatic digestion provides more appropraite condition.Animal will stimulate and quicken lactic acid bacteria and form in digestion process, help the digestion and the absorption of nutriment.Straw is rolled through high temperature in addition, changes physicochemical property, makes it ripe by changing, and sterilization has strong paste fragrance, good palatability, grazing rate and digestibility height.Grazing rate can reach more than 98%, and digestibility can reach more than 80%.Save feed cost, reduce metabolic disease.And time saving and energy saving when feeding, reduce labour intensity, increase work efficiency.Overall utilization rate is better than sheep's hay.Stalk micro storage is exactly that agricultural crop straw is added the high-efficiency activated bacterial classification of microorganism---jujube stalk fermentation dried bacterium alive, put into the fermentation of certain airtight container (as concrete floor, crypt, cylinder, polybag etc.) or ground, through certain sweat, agricultural crop straw is become have acid, perfume (or spice), vinosity, the feed that domestic animal is liked.Because it is by microorganism the feed in the storage to be fermented, so claim little storage, its feed is microbiological fermented feed.

Summary of the invention

The present invention relates to the preparation method of the little storage of a kind of maize straw,, agricultural crop straw is become have acid, perfume (or spice), vinosity, the feed that domestic animal is liked through certain sweat.This method have pollution less, the efficient height, cost is low, period of storage is long, be beneficial to characteristics such as suitability for industrialized production.It is characterized in that implementing by following four aspects: the first, sugar 2 grams are poured in 25 kg water, after the dissolving, add dried bacterium 3 grams of living again, place 1--2 then at normal temperatures and bacterial classification was brought back to life in individual hour, become the bacterial classification of resurrection.The second, pour in the saline solution of abundant dissolving (8 kilograms salt, 800 premium on currency) and mix thoroughly bringing back to life good microbial inoculum.The 3rd, the 1000 kg corn stalks that prescind are layered on the end, cellar for storing things, thick about 20～25 centimetres, evenly spray bacterium liquid, after the compacting, repave 20～25 centimetres of stalks, spray bacterium liquid, compacting again, up to being higher than 40 centimetres of entrance of cellars, evenly spill the salt powder at the top one deck, plastic sheeting seals on the compacting bonnet again.The consumption of salt is every square metre 250 gram, cover plastic sheeting after, spread the stalk of 20～30 cm thicks in the above, 15～20 centimetres of earthing, sealing.The 4th, grasp the stalk sample, with the hands turn round stubbornly, if there is water to drip, its water content is about more than 80%; If no water droplet, see that moisture clearly is about about 60% to hand after unclamping, the microbiological fermented feed water content is ideal 60%～65%.

Specific implementation method

1. sugar 2 grams are poured in 25 kg water, after the dissolving, added dried bacterium 3 grams of living again, place 1--2 then at normal temperatures and bacterial classification was brought back to life in individual hour, become the bacterial classification of resurrection, the microbial inoculum for preparing must use up the same day.

2. will bring back to life good microbial inoculum pours in the saline solution of abundant dissolving (8 kilograms salt, 800 premium on currency) and mixes thoroughly.

3. the 1000 kg corn stalks that will prescind are layered on the end, cellar for storing things, thick about 20～25 centimetres, evenly spray bacterium liquid, after the compacting, repave 20～25 centimetres of stalks, spray bacterium liquid, compacting again, up to being higher than 40 centimetres of entrance of cellars, evenly spill the salt powder at the top one deck, plastic sheeting seals on the compacting bonnet again.The consumption of salt is every square metre 250 gram, its objective is to guarantee that microbiological fermented feed top mould evil idea does not take place goes bad.After covering plastic sheeting, spread the stalk of 20～30 cm thicks in the above, 15～20 centimetres of earthing, sealing.Behind the stalk micro storage, bin stock can slowly sink in the pond, cellar for storing things, should in time add a cover and make it above ground level, and dig the gutter around, in case rainwater infiltrates.

4. grasp the stalk sample, with the hands turn round stubbornly, if there is water to drip, its water content is about more than 80%; If no water droplet, see that moisture clearly is about about 60% to hand after unclamping, the microbiological fermented feed water content is ideal 60%～65%.
