摘要：In order to determine the optimization technology of bio-fertilizer, the aerobic fermentation test was done by taking fresh manure and rice husk powder as material. The inoculation, moisture content, C/N ratio and turning frequency were selected out to do single-factor test. Then the optimal conditions in the first fermentation were obtained through orthogonal experiments. After the first fermentation, the second fermentation was done by adding the complex microbes with ability of releasing potassium, dissolving phosphate and fixing nitrogen. The ending time of second fermentation was determined by testing the growth condition of beneficial bacteria in the fermentation process. As was shown in the result, the optimal parameter in the first fermentation was moisture content of 70%, C/N ratio of 20:1, inoculation of 3‰, turning frequency of once every three days. After a period of fifteen days of fermentation, the germination index could reach 91.3%. Then the six-day second fermentation was conducted and the germination index increased to 98.8%. Under this optimum condition, the material could heat up fast and the top temperature could be high with a long duration. ? Fu et al.; Licensee Bentham Open.
