I. Several basic conditions for the normal operation of the fermentation bed

After the ecological fermentation bed has been constructed, the next task is to start and run. The use of the Fertilizer fermentation bed fermentation agent can be started in 1-3 days in the summer, and it is a cold winter of minus 10 degrees or even tens of degrees. The heat preservation measures are good and will start within three to five days. It can be seen that the startup of the Jinbao fermentation bed is very simple and is not affected by the seasonal climate. The emphasis is on the daily management and post-maintenance of the fermentation bed in the process of operation.

To ensure the normal operation of the fermentation bed, it is necessary to first understand the basic conditions for the normal operation of the fermentation bed, namely the species, the thickness of the litter, the moisture in the litter, the temperature, the nutrients needed for the bacteria (provided by the excreta), and Ventilation, ventilation, etc. The importance of bacteria is self-evident, because the decomposition of pig's excreta depends on the life activities of microbial strains. The types of microorganisms, the strength of microbial activity, the number of strains and their activity are all extremely important. , Jinbao fermentation bed fermentation agent contains more than a dozen beneficial functional microorganisms, the number of functional viable cells above 3.5 billion / g, all strains have been bred and rejuvenated; moisture is also very important, fermentation bed strains more appropriate water in the 60 %, if the water content is high or low, it will directly affect the decomposition of the excreta; the thickness of the bedding is an important standard for the production of fermentation beds, and the goldfish fermentation bed requires 50 centimeters (other manufacturers' fermentation beds generally require a thickness of 80-100 centimeters. The thickness of the litter, which is the thickness of the microorganisms can normally decompose the feces, excessively lower than this thickness, the "core fermentation layer" is forced into a "protective layer" or "buffer layer", the functional bacteria fermentation really needed The "core fermentation layer" disappears and there is no space for the functional bacteria to survive and multiply. This will lead to a decrease in the ability of the microorganisms to decompose the feces, or to terminate them. Therefore, the basic thickness of the litter should be guaranteed. . The general temperature range (from minus tens of degrees outside the ambient temperature to 45 degrees above zero) has little effect on the viability of the already started fermentation bed, but it has a great influence on the growth of the pigs in the fermentation bed, and the temperature is too high or too high. Low will affect the pig's intake and growth. Due to the restrictive factors mentioned above, it is possible to ensure the safe, continuous and stable operation of the fermentation bed by adjusting the ventilative air permeability of the housing.

Second, non-standard fermentation bed bad scourge

Breathability of the fermentation bed house directly affects the vitality of the bacteria species and the moisture and temperature of the house. Poor ventilated ventilation generally leads to the following adverse consequences.

1, fecal decomposition is slow or does not break down. Poor ventilation results in little or no heat, and litter temperature is low. This is mainly due to the fact that most of the bacteria in the fermentation bed are oxygen-consuming strains. If there is a lack of oxygen in the housing, microbial activity will be greatly inhibited. Decomposition of feces or failure to disintegrate in time will lead to excessive accumulation of feces, heavy ammonia, and high concentration of carbon dioxide in the pens. The anaerobic bacteria are active and produce harmful gases such as humic ammonia, ammonia, hydrogen sulfide, etc. Air irritates the mucous membranes of the respiratory tract, causing mucous membrane congestion, resulting in conjunctivitis and respiratory diseases; hydrogen sulfide is a strong neurotoxin, has a strong irritant, can also cause eye conjunctivitis and respiratory diseases, so that pigs can not grow normally or grow slowly. .

2, increase the humidity or drops of water droplets. For the normal and stable operation of the fermentation bed, due to a large amount of water vapor, carbon dioxide and other gases generated during the operation process, timely or regular ventilation is required to discharge these gases out of the housing. If it is not discharged in time, it will be easy to fog in the winter housing. , At the same time, water vapor rises in case of poor ventilation and cold plastic film ceilings, or foamed plastic ceilings, color steel plates, etc., will condense into water droplets and even form a drop back into the fermentation bed, resulting in partial or entire fermentation bed surface moisture, poor ventilation It eventually led to death or bad beds in the fermentation bed strain, resulting in the production of a large number of fly maggots, pigs sleeping on colder beds, and the risk of colds. Poultry larvae in poorly ventilated corners are also often found in poorly ventilated housing.

3, house hot or cold cold. The poor ventilation of the winter fermentation bed house will cause the temperature of the housing not to go up. The winter temperature is too low and the pig will catch cold and grow slowly. In the summer, bad ventilation will cause the air in the fermentation bed to be stuffy, excess heat, carbon dioxide and ammonia. Can not spread or spread too slowly, affect the healthy growth of pigs.

Third, take effective measures to improve ventilation

Ventilation of the pens is affected by many aspects, summer and winter are not the same, North and South are not the same, dry and wet areas are even more different, should be timely, according to local conditions, to take effective measures to improve ventilation ventilation of the pens and promote the health of pigs Fast growth.

1. The structure must be reasonable. First of all, we must start from the structure of the pen quarters. The pens are best to face south and south and north and south, with certain spans and heights, places with high ground, etc. (Specific information can be requested from the company).

2, to ensure that the "four windows" complete. Jinbao Fermenting Bed Technician reminds: For large and medium-sized farmers or farms with conditions, overall windows, skylights, windows, and induced draft fan windows should be considered as a whole (small-scale or retail households have lower requirements for breeding, with skylights, windows, and Conventional windows can be used to provide both natural ventilation and mechanical ventilation. When the air circulation is good, the windows can be opened for ventilation (opened in summer, opened in winter and opened at 12 to 14 noon in winter, and closed in the evening). The purpose of opening the sunroof is to discharge ammonia gas and other low molecular weight gases. The ground window is a gas with a relatively large molecular weight such as carbon dioxide. Windows and windows have a better effect on the discharge of water vapor. In hot weather, when the air flow is affected by yin, or when the temperature inside or outside the room exceeds 10 degrees, consideration should be given to Fans are forced to ventilate to enhance air flow and avoid excessive heat and heat exchange due to window opening.

3, timely upset shake. According to the technicians and users of the Fertilizer Fermentation Bed, the timing of upsetting the fermentation mattress material has a significant effect on the breathability of the fermentation bed. The purpose of the turbulence is firstly to increase the air permeability of the litter and prevent the litter from being excessively compacted to cause partial or short The anaerobic fermentation can dissipate a large amount of water vapor during the second turbulent process, which can effectively reduce the moisture and heat in the fermentation bed (in the summer, this tumbling is particularly effective and can quickly adjust the moisture). When you turn over, you should open the window or draw the fan to make the water quickly lost.

4, cement brick partition to change the iron fence. Increasing the ventilation performance in the housing also reduces the retarding effect of various unreasonable facilities on the flow of air. If the existing columns are separated by common brick walls, they should be separated by iron fences, which can greatly reduce the air flow resistance. It also reduces dead air flow (air, ammonia, carbon dioxide, and other harmful microorganisms are extremely high).

The fermentation bed housing is well-ventilated and ventilated, coupled with other supporting measures, the basic guarantee for the safe, continuous and stable operation of the fermentation bed. (All rights reserved, please indicate the source!)
