| Fermented quality and substances contained in cultivated materials have a direct impact on the yield and quality of Agaricus bisporus in the industrial production processes of Agaricus bisporus.It is a economic,environmentally friendly way to utilize agricultural solid waste resource as the materials in cultivating Agaricus bisporus. In recent years, material changes and microbial diversity has been a hot topic durng the process of high-temperature composting. With the continuous expansion of agricultural production, agricultural waste is increasing circulatory problems of agricultural waste will be a hot issue,This study focused on the formulation of cultivated material and fermentation process.There are three trials (the recipe for cultivated material of Agaricus bisporus, material change and microbial diversity in the fermentation process of industrial production in Yixing material change in different layers of materials of industrial production in Jintan and microbial diversity) concluded in this study to explore the change law during composting.1.In the first recipe test, traditional straw were used as the control,,besides that, there were another four different treatment using wheat straw and manure as materials in different proportions. Each treatment were added in the same amount of accessories.The final results showed that:In matrix formulation experiments, using wheat straw as the main raw material could grow Agaricus bisporus, but the growth rate under different formulations including hyphae, hyphae cover time and squaring time were significantly different, but the second and third treatment had no significant difference, which was significantly higher than other treatments, the results show that when the carbon-nitrogen ratio is about 30, the growth rate of hyphae is higher, hyphae cover shorter time and squaring time is shorter. Taking the utilization of agricultural waste into account, recipe adds adding dung cow manure is more practical.However, the experiment showed that wheat straw as a matrix raw material for cultivating Agaricus bisporus has some potential and feasibility, but it requires further experimental verification.2.In this industrial fermentation experiments, we research studied the law of variation of biological substances and materials in the index, including pH, organic matter, total nitrogen, and related enzymes and microbial diversity in Yixing with advanced facilities controlling temperature and humidity. Experimental results show that the plant material during composting fermentation process basic pH was maintained at 7.5-8.5, basically at a suitable pH range. Maintain the pH in the proper range, and promoting metabolic activity of microorganisms. In addition to the entire post-composting process, organic matter content are constantly reduced, reduced by nearly three percentage points. Absolute reduction in total nitrogen content, relative content has increased. Cellulose, hemicellulose, lignin, ash, and various changes in microbial activity and the number of changes in the underlying positive correlation.3.This test is a comparison about the law of material changes in different layers in the fermentation process in Jintan factory. We got samples from upper,middle and lower layer in cultivated material,then research the law of materials and microbiology change in different layer by testing basic physicochemical properties and the amount of microbiology.The experiments show that the law of material change in Jintan is similar to that in Yixing, The middle layer fermented best with better water retention, proper pH and the fastest rate of decomposition of macromolecules as well as the maximum amount of microbiology. It is visible that turning fully and fermentation technology are both important to the quality of cultivated materials.These provide a theoretical basis to further explore the activity of microbiology and the separation and identification of preponderantadvantage microbiology. |
