The "four-window complete" theory of fermentation bed
The "four-window complete" theory of fermentation bed
The normal operation of the fermentation bed must be well ventilated. Through ventilation, the temperature, humidity and other factors in the fermentation bed can be adjusted to ensure the safe, continuous and stable operation of the fermentation bed. So just like the goldfish fermentation bed often mentioned: ventilation - the normal operation of the fermentation bed is essential, such as the Jinpo fermentation bed requirements are more stringent, we must complete four windows, let's introduce why the Jinbao fermentation bed requires such condition:
The four windows of the goldfish fermentation bed are: skylights, windows, conventional windows, induced draft fan windows. Their role in the setting mechanism are: 1 skylight: the role of the sunroof is to emit ammonia gas and other small molecular weight gas; 2 the role of the window is to emit carbon dioxide and other relatively high molecular weight gas; 3 windows and windows on the discharge of water vapor The effect is better, regulate the moisture in the fermentation bed, so that the humidity of the fermentation bed is maintained within a certain range; 4 In the hot weather, the air flow is affected by yin, or the indoor and outdoor temperature exceeds 10 degrees, the use of forced draft fan should be considered Sexual ventilation to enhance air flow, avoiding excessive heat and heat exchange caused by window opening.
The feces after the role of the function of the golden treasure microorganisms, produce a large number of harmful gases such as ammonia, ammonia, hydrogen sulfide, carbon dioxide, and other gases, high concentrations of ammonia stimulate the respiratory mucosa, causing mucosal congestion, resulting in conjunctivitis and respiratory diseases; Hydrogen sulfide is a strong neurotoxin and has strong irritation. It can also cause conjunctivitis and respiratory diseases, making pigs unable to grow normally or grow slowly. Ventilation and ventilation of the fermentation bed directly affect the viability and circle of bacteria. The moisture, temperature, etc. of the house, poor ventilation and air permeability will cause the manure to decompose slowly or not to be decomposed, and even the phenomenon of dead bed, increased humidity, or drops of water droplets, stuffy heat or colds. Therefore, the fermentation bed must have "four windows complete." Generally, the sunroof can be opened at night when the temperature is high at noon, and closed at night; if there are no conditions for the small and medium-sized pig farms to draw fan windows, there must be three other windows.
