The choice of dry fermentation mattress material
First, dry spreader bed selection of litter standard. 1. Brief introduction of fermentation bed. The dry-sweeping fermentation bed culture method is an eco-friendly breeding method and is usually the first choice for ecological agriculture. The key to the dry-sweeping fermentation bed culture method lies in the thick bedding with fermentative bacteria laid on the ground of the livestock and poultry housing. The dry-sweeping fermentation bed consists of thick litter. The litter is rich in micro-organisms. These micro-organisms are carefully screened and cultivated to efficiently decompose animal excreta and produce harmless water, carbon dioxide and ammonia. These metabolic wastes are mainly ventilated and discharged outside the housing, eventually achieving the purpose of eliminating environmental pollution. In summary, it can be seen that the dry-sweeping fermentation bed has no manure, water and manpower, and basically eliminates the environmental pollution caused by excreta. The author found that the air in the pens was slightly fermented after being field-tested. The air quality is much higher than that of traditional culture, and the house is very clean. Except for sawdust, it is difficult to see the accumulation of manure. The quality of dairy products, eggs, and meat produced by livestock in such an environment can be imagined. However, although the operation of the dry-spreading fermentation bed is simple, management is also a meticulous activity and technology. It requires a certain amount of knowledge and management methods. There are mainly two kinds of fermentation beds, traditional wet fermentation beds and new dry fermentation beds. The dry-spreading fermentation bed is an improvement over the traditional wet fermentation bed. The traditional wet fermentation bed needs to be fermented with water for about ten days before it can be used for breeding. Moreover, the bed body has high humidity and is likely to generate malodorous gas and breed mosquitoes and flies. Health has a certain impact, and the dry-sweeping fermentation bed does not need to be pre-fermented by adding water. After laying, the livestock and poultry can be directly driven into the fermentation bed. 2. The importance of litter to the fermentation bed. The dry-type fermentation bed is mainly composed of litter and fermentation strains, and it is the fermenting bacteria that really play a role in decomposition. The fermenting bacteria can decompose the animal's excreta through self-metabolism, thereby realizing the defecation effect of the fermentation bed. Strains are the heart of the fermentation bed. But isn't litter important? Obviously, litter is important. The litter is the habitat for the microbe of the fermentation bacteria. Fermentation microbes and humans also have certain requirements on the living environment, and compared to humans, microbes are more susceptible to external environmental factors, so they need to have a special place for their survival - litter. Therefore, the litter is very important for the dry-sweeping fermentation bed, and whether the various parameters of the litter directly determine whether or not the microbes of the extra bed can be normally metabolized to decompose the fecal urine. 3, how to choose litter is the choice of litter. The choice of litter should be considered from two perspectives. (1) speak from the perspective of the animal. The dry-sweeping fermentation bed is a place of daily life for animals, so the litter of the dry-sweeping fermentation bed should be harmless or even beneficial to animals. From this perspective, the litter should be free from unpleasant odors and even emit substances that are conducive to the growth of animals. Unpleasant odors can easily cause animal production to decline. The litter should have a certain density and hardness. If the density is too small, it will easily cause flocculation and affect the air quality. If it is too hard to form needle-like substances, it will cause harm to the animal skin, which is not conducive to the animal lying down; The litter should have good water absorption and water retention, and good water absorption can quickly spread excrement and urine into the fermentation bed. This will not cause water accumulation and affect animal activity. Good water retention does not allow liquid such as excrement to quickly sink into the bottom layer, and the litter is easily wetted and dry, and the moisture distribution is uneven, and the surface layer is easy to dry and dust. (2) From the point of view of microbial strains on the fermentation bed. The litter and microorganisms together make up the fermentation bed. The litter is the only environmental basis for the survival of microorganisms. Therefore, the choice of litter should be more suitable for the survival of microorganisms. The dry seed fermentation microorganisms are composed of a variety of beneficial microorganisms. These microorganisms are mainly aerobic microorganisms. Their survival requires certain temperature, moisture and oxygen. Therefore, the choice of bedding should be considered from these aspects. . In terms of temperature conditions. The survival of microorganisms requires a certain temperature, and the temperature of the litter depends mainly on the ambient temperature and the heat production activity of the microorganisms. In combination of these two factors, litter should have a certain degree of ventilation and thermal conductivity, so that too much heat production can be evenly distributed, so as not to cause the temperature of the fermentation layer is too high. The litter also needs to have a certain degree of heat insulation so that it can ensure that the heat produced by the fermentation will not be excessively lost due to the low temperature outside, resulting in a low temperature of the fermentation bed of the fermentation bed, which is not conducive to fermentation. In terms of moisture. The litter should have a certain degree of water absorption and water retention, so that the moisture will not be lost too quickly, and certainly not too strong suction will easily lead to excessive humidity. In terms of oxygen. The litter should have a certain amount of breathability, which can ensure the survival of the bacteria species. In terms of the needs of the combined microorganisms, the litter should have a certain breathable moisture and heat insulation effect. (3) Summary. Through the above analysis can be seen, litter needs to have a certain degree of hardness, a certain density, a certain degree of water absorption, a certain degree of permeability, a certain degree of water retention and a certain degree of heat insulation. friendly reminder: For more details on the exciting content of dry-sparing fermentation beds, starters, and microbiological fertilizers, please pay attention to the official website of Jinbao Dry Fermenting Bed and Huaxia Kangyuan Taobao Factory (https://bjhxky.taobao.com).
