The promotion and demonstration of the dry fermentation and aquaculture technology has now been widely applied in various regions of the country to effectively respond to the wet and rainy climate in the south and the cold and dry climate in the north, so as to achieve pollution-free, zero-emission, cost-saving, disease-free and meat-fresh green farming. The environment-friendly breeding mode has greatly improved the economic benefits of farmers.
Fermentation bed farming, litter and strain selection are key. The merits of litter directly affect the fermentation effect of the fermentation bed, so careful selection is crucial. In addition, the fermentation bed strains should be guaranteed to have a brand with a national official invention patent.
Fermentation bed breeding livestock, litter selection is the key, the laying of the fermentation bed is divided into about four layers, the advantages and disadvantages of sawdust directly affect the fermentation effect of the fermentation bed, but not with light sawdust, sawdust is too thin, airtight, does not meet the fermentation bed Oxygen consumption characteristics of fermented manure. The fermentation mattress material consists of two or more of sawdust, rice hulls, peanut husks, and straw. It is recommended that pig mattresses should be laid at 50 centimeters. The thickness of sawdust is 20 to 30 centimeters. Sheep, rabbits, dogs, chickens, The duck mattress material thickness is 25 to 30 centimeters, and the sawdust thickness is 15 to 20 centimeters. The bottom of the mattress material can be selected from rice husk, peanut shell and straw.
Why should you choose sawdust?
1. The litter must have strong water absorption, sawdust soft texture, can absorb more water, can effectively adsorb odor components, decompose the feces into the sawdust gap, denitrifying bacteria, lactic acid bacteria, yeast, spores for fermentation bed Bacillus, etc. are also adsorbed on litter and added with air permeability, thus forming a good environment for fermentation and decomposition of assimilation of feces, that is, the function of the litter adsorption and the function of the bacteria are combined to achieve good results.
2. Sawdust has the highest ratio of carbon to nitrogen in all litter, and it is most resistant to fermentation. In addition, sawdust has a high degree of lignification and has loose surfaces. It has no nutritional value, is not easy to mold, is not prone to mycotoxins, and is effective. Extend the use of fermentation mattress materials.
3. The litter must have a certain strength, and it will not go on as soon as it is pressed. Therefore, sawdust also has a certain strength, but straw will not work, and it will be too soft.
4. The litter must be matched with the thickness. If the light is sawdust, it is impermeable to air. The fermentation in the fermentation bed is aerobic and the breathability can ensure sufficient fermentation. Therefore, with a proper mix of rice hulls, peanut hulls, and straw, rice husks, with the exception of non-absorbent water, are suitable in thickness and meet the basic conditions for fermentation mattress materials.
What kind of sawdust is the best choice?
1. The source of sawdust should be clear. It must be ensured that sawdust is non-toxic and mildew-free. The best is fresh dried sawdust. Do not use sawdust of toxic trees, such as beech wood, otherwise it will cause poisoning.
2. Natural sawdust in the primeval forest is good because the fresh wood harvested from the original forest does not have any pollution, and the production of a fermentation bed is the best. But try not to use sawdust with too much oil, such as pine wood and Chinese wood. In principle, sawdust generated from artificial boards containing glue or preservatives is also not used because the added substances contained in such sawdust may be toxic and may have an inhibitory effect on the fermentation process. If it must be used, mix it with other sawdust and lay it on the bottom, or mix it with a small amount of sawdust.
3, to avoid the residual chemical substances in sawdust, such as the secondary processing of wood preservatives, paint, asphalt and other chemical substances, so the effect of fermentation bed not only is not good, but also affect the growth of livestock.
4, some of the impurities with sawdust and sawdust chemical residues, an unpleasant pungent odor (such as Chinese pine sawdust) to go through the drying, cleaning, and then dried production fermentation bed, so that most of the harmful substances have been separated off or degrade , Reduced residue, thereby reducing the hazard.
