In the cold and dry environment in winter, the maintenance of the fermentation bed is relatively simple; but in the summer of high temperature, high humidity and abundant rain, the maintenance and management of the fermentation bed requires the farmers to pay attention to the relevant skills in order to obtain good results. Regulate the following requirements: Area requirement The area of ​​a single pig house should generally not be less than 15 square meters, preferably more than 20 square meters, and the area of ​​a sow house should not be less than 7-8 square meters. Generally speaking, where the cost of land and infrastructure can be tolerated, the larger the area occupied by each pig, the better, because the larger the area, the stronger the buffering and tolerance of the fermentation bed (ie the resistance to stress) is. . If a corner of a large-scale fermentation bed is filled with some rainwater, the moisture in the corner is too high, and the fermentation is decomposed slowly or stopped. However, this is only a small part. Other sites also have conditions suitable for the normal operation of the fermentation bed. The operation of the entire fermentation bed; but if the area is very small, for example, only 89 square meters, a corner of rainwater will occupy two or three square meters, accounting for 20%-30% of the whole fermentation bed, the original fermentation bed due to the actual work The area is not enough and it is overworked. Now, due to the rain, the fermentation space is reduced. “The house leaks are affected by the night rain.†Two unfavorable factors are caught and attacked, and the load is greatly overloaded, resulting in the fermentation bed degrading faeces, deodorizing, and promoting growth. The effect is not obvious or basically lost. Therefore, the use of strains to produce fermentation beds requires area: at least 15 square meters, which can be large or not, and is better when the cost of civil construction can be tolerated. For areas under 15 square meters, except sows (sows) The area of ​​the house should not be less than 7-8 square meters. It is not recommended to use pigs in a fermentation bed. Density requirements After the area of ​​the fermentation bed has been fulfilled, do not think that any number of pigs can be cultured in this space. This view is wrong. Fermentation bed technicians prompt farmers: the fermentation bed also has a requirement for the culture density. For finishing pigs, each pig is required to occupy 1.2-1.5 square meters. Above this density, the fermentation bed may be overloaded, resulting in undesirable phenomena such as excessive fermentation and the termination of fermentation. The bigger the pig's head and body weight, the more necessary it is to provide more area. Because the capacity of microorganisms within a unit volume to handle feces is limited, if each pig excretes 3-5 kilograms of feces per day, it takes about 1.2 to 1.5 square meters (depth of 50 cm) of microorganisms to degrade for 1 day to complete. . If each pig occupies only 1 square meter, then there will be excess feces left every day, resulting in incomplete or untimely decomposition, and as the pig grows bigger, the amount of excreted urine will increase every day. The long-term accumulation of excessive excreta will cause abnormal disorder in the fermentation bed system and cause serious crashes. Humidity requirements Humidity includes air humidity and litter humidity. For example, in the rainy season, a long time of rain will cause the litter to absorb the moisture in the air. In this case, the operation of the fermentation bed is generally not affected. If you feel that the litter is too wet, you can clear out some of the litter and then add it to the fermentation bed and reuse it, or add new dry litter to reconcile the moisture, and increase the frequency of turning over to make the water in the form of water vapor. Evaporate away as soon as possible. If the litter on the roof is too moist, the litter that has been contaminated by the rainwater and wetted should be removed immediately, dried or dried and then backfilled into the fermentation bed for reuse. In short, try to ensure that the fermentation bed has a relatively dry surface, and certainly not too dry, such as long-term no rain in the northern regions, litter is easy to dust, this time, we should spray a small amount of spray on the litter, the standard surface is not It is easy to raise dust. Ventilation requirements The fermentation bed requires that the pens be transparent to the north and south, and the ventilation is smooth. Therefore, ventilation and light must be taken into account in the construction of the pig house. Therefore, the fermentation bed must have a certain span and height, and the span requirement is generally not less than 8 meters. Designed to be 8-12 meters, the height of the pig house should not be less than 2.6 meters (refer to the height of the bed from the roof), the length can be adapted to the local conditions, every three meters or so should be provided with the ventilation of the ground window. In this way, air in the pens can easily form convection and achieve good ventilation and ventilation effects.
