At present, most pig beds use fermentation beds to raise pigs, and the fermentation beds need to be covered with sawdust or corn flour, plus some microbial agents produced by regular manufacturers. Fermentation bed culture technology refers to an ecological culture mode which comprehensively applies the principles of microbiology, ecology and fermentation engineering and takes active functional microorganisms as the "transformation center" of material energy. The core of this technology lies in the long-term, sustained and stable transformation of animal manure waste into useful substances and energy, and at the same time, the complete degradation of animal manure such as pigs is realized, so as to achieve the purpose of no pollution and zero emission. Fermentation bed culture technology is the latest environmental protection culture mode in the world, which has been applied in Europe, America, Japan and South Korea for a long time. Since 1990s, experts and professors from all over the world began to systematically study and practice pig raising in fermentation beds, and gradually formed a relatively perfect technical specification. In 2008, after Beijing Huaxia Kangyuan Technology successfully popularized and applied Gymboree dry-laid fermentation bed technology, it officially declared the national invention patent of Gymboree dry-laid fermentation bed, which marked the great progress of fermentation bed from wet fermentation bed with water to dry-laid fermentation bed without water. In recent years, China has applied this technology to aquaculture and achieved remarkable results.
Gymboree fermentation bed starter is an efficient compound microbial agent produced in Beijing, which belongs to the first natural compound microbial agent in China. It is made by using the research technology achievements of dozens of well-known domestic scientific research institutes, such as Academy of Agricultural Sciences, Academy of Agricultural Sciences, Academy of Military Medical Sciences of the People's Liberation Army, combined with the latest international microbial engineering technologies and processes in Germany, the United States, Japan and South Korea, combined with independent patent technology and intellectual property rights, through high-tech screening, purification, rejuvenation and other special processes. The preparation is mainly composed of natural beneficial microorganisms such as filamentous fungi, yeasts and actinomycetes. ?
