1. Production of EM strain fermentation broth - EM stock solution
A, bacterial species activation: 10 grams of EM bacteria, brown sugar, 0.1 kg (the brown sugar is first dissolved in water), add 1 kg of water. Note: (Water is heated to 100C and then red pond or white sugar is added, then heating is continued for 5 minutes. When cooled to 40C, EM seeds are added). Fermentation (35C-40C temperature) is conducted for 3-5 days, and the container is opened. Succeeded in the sour and sweet taste. Used as a liquid strain.
B. Making stock solution: Add the activated liquid bacteria to the secondary fermenter (water ratio: 1:10 ratio) + (10% sterile sweet water! 1% amino acid! Temperature 35-40 degrees! Fermentation 5 -7 days!)
The standard of finished fermentation broth (odor: sweet and sour! PH value: 4.0-5.0! Viable content: 10 billion/ml!)
2. Fermentation Bed Fermentation Fluid of EM Strains When the fermentation bed is used for a period of time, a certain EM strain fermentation liquid may be sprayed thereon to increase the degradation efficiency. The EM strain fermentation liquid is mainly used to regulate the activity of the soil microbial environment. In particular, when the activity of soil microorganisms is reduced, dilute the EM strain fermentation broth to the appropriate proportion to spray the bed surface to accelerate the degradation and digestion rate of excrement. In addition, when it is usually found that there is a lot of pig stool, put it. Spread a sprinkle to the open space to facilitate the full decomposition of the feces. Therefore, the rational use of active agents plays a very important role in the recycling of the fermentation bed. EM strain fermentation broth has developed a number of commercial products, use to select the product suitable for microbial growth in the fermentation bed, and spray according to the actual situation.
3. Production of Fermented Mattress Material The main ingredient of the fermentation bed is composed of organic litter. The main ingredient in the litter is wood chips, accounting for 90%, and the other 10% is soil and a small amount of coarse salt. Sawdust is very soft and can absorb moisture; coarse salt is beneficial to the decomposition of sawdust. The total thickness of the padding is about 90cm. For example, a pig house with an area of ​​25m2 is about 25m2150kg = 3750kg. If the conditions are good, you can shop 30-40cm depth of the first, and then spread the sawdust, if the sawdust is not sufficient, you can shop 50cm deep corn straw or 30cm thick rice skin, and then covered with sawdust. Soil: The amount is 10% of the total material, which is 415kg. The soil requirement is clean soil without chemical fertilizers. Salt: 0.3% of the total material, 12kg; Microorganisms: 2kg per square meter, 50kg. Water: 1000kg; 8kg of nutrient solution (mixture of EM strain fermentation broth, animal amino acid, rice vinegar, etc.).
The original species of soil microorganisms, rice bran and sawdust are mixed in a certain proportion, and a certain amount of nutrient solution and amino acid solution are added to make the water content reach 60%, so as to ensure the proliferation of beneficial bacteria. It is also ideal to add a small amount of distiller's grains, chaff smoked carbon, and chaff. After 2 to 4 days of fermentation, organic litter for the fermentation bed can be made. The litter of the fermentation bed is not changed for 10 years and 20 years. A small investment can be used permanently.
4. Construction of pig houses The construction of pig farms for pigs in the fermentation bed is also very important. It can be modified on the basis of the original pig houses. It is generally required that the pig houses should face south and south from east to west, and be fully lighted and well ventilated. The north and south can be opened. The net area of ​​each pig is usually about 25 m2. 15-20 pigs can be kept. The height of the piggery wall is 3m. The height of the roof is 4.5m. There is a free-opening window in the middle of the roof facing the south. The sunlight can illuminate the entire window. One-third of the pig bed area, and from the sun rises to the sun, can irradiate every corner of the whole pig bed. This will allow the microbes inside the pig house to grow and reproduce more properly, which is conducive to fermentation. The automatic feeding trough is built on the north side, and the automatic water diverter is built on the south side, so as to meet the requirement of odorless and fly-free pig house. If greenhouses are used, it will save both money and money because of the low cost of greenhouses and the easier adjustment of the microclimate. In winter, when the lighting is good and the temperature is kept warm, the pigs can safely pass the winter; in the summer, the sunshade film is put down, and the skirt film can be shaken to cool the air.
5. Preparation of the fermentation bed The fermentation bed is divided into underground fermentation bed and above-ground fermentation bed. In the south, the groundwater level is relatively high, and the groundwater type is generally adopted. If the groundwater level is relatively low in the north, underground water is generally used. The underground fermentation bed requires deep digging 90-100 cm below the ground to fill up the organic mat made. The piglets can then be placed and the pig can grow freely. Where groundwater levels are low, ground-based fermentation beds can be used. The ground-based fermentation bed is built on the ground and requires a certain depth, and then it is filled with the organic litter that has been made. The pigs raised on the fermented bed returned to the “home-grown†environment. The pigs were free to play, they returned to their nature, they were in a good mood, they naturally ate more, they grew longer, and all were bright and cheerful.
6. The management of the fermentation bed is generally similar to the routine management of conventional pigs, but the fermentation bed has its own unique place, so the usual management also has different places: 1 pig breeding density, the number of pigs per unit area over In many cases, the state of fermentation of the bed will be reduced, and the pig's excreta will not be rapidly degraded and digested. Usually, an area of ​​1.2-1.5 m2 per pig is appropriate. When piglets are used, the breeding density can be increased appropriately; 2 The bed of the fermentation bed cannot be Too dry, a certain humidity is conducive to the reproduction of microorganisms. If it is too dry, it may lead to respiratory disease in pigs. It can regularly spray the active agent on the bed; 3 In order to remove the parasites from the body, the surrounding pigs must be thoroughly removed to prevent parasitism. The insects are brought into the fermentation bed to prevent the pigs from bringing the eggs into the body once they are licking the mycelium. The disease should be closely monitored. 4 It is necessary to pay close attention to the activity of the soil microorganisms. If necessary, an active agent should be added to regulate the activity of the soil microorganisms in order to ensure Fermentation can be carried out normally; 5 When the amount of sawdust in the pig house is reduced, the original species and nutrient solution of microorganisms are properly supplemented; 6 is to help the pig arch to turn over the ground, and the amount of pig feed should be controlled 80% of the constant, live pigs usually defecate in a fixed place, pee, when the excrement piles digging pits can be buried; 7 the ground humidity must be controlled at 60%, should be checked frequently, such as excessive water should open the vents, The use of air to regulate humidity; 8 prohibit the use of chemicals and antibiotics in the pig house to prevent them from killing microorganisms in the soil and reduce the activity of microorganisms.
After spreading the sawdust, soil, and microorganisms layer by layer, spray salt, water, and nutrient solution. Moisture content should be adjusted to 65%. Spray water should start after filling 50% of the material. Put the pigsty in this order. The litter can be filled and after a few days of feeding, the odor disappears naturally due to the action of the original microorganisms, and the flies and cockroaches no longer reproduce. After 2-3 months, the lower layer of the pig bed becomes natural reproduction, and the middle of the pig bed becomes white. Bacteria, whose temperature can reach 40-50°C, become a pig's feed after fermentation of pig manure.
