碩士 === 東海大學 === 畜產學系 === 87 === Abstract The object of this study were conducted with the layer waste by adding particular mix microorganism which was microorganism laboratory of Tunghai University content Bacillus subtilis、Bacillus licheniformis、Lactobacillus plantarum、Actinobifida chromogena、Mucor pustillus and Food Industry Research and Development Institute content Thermoactinomyces vulgaris、Saccharoployspora rectivirgula、Clastridium stercorarium. In this experiment, the function of particular microorganism was to speed the rate of decomposition, decrease ammonia and then transfer the layer wastes into highly stable organic fertilizer.The layer wastes were used during the composting. The temperature of treatments adding microorganism laboratory of Tunghai University was higher and last longer than controls. Besides, the highest temperature was 68 ℃ and occurred on the fourth day. The results of composting experiments were indicated that composting increased the concentration of N, P, K, and adding microorganism contens more N than controls. The volume of CO2 compost treatment was add microorganism laboratory of Tunghai University and sawdust which release large amount in early stage, but decreased rapidly after early stage. In addition, this treatment made lower product of CO2 than other treatments during the period of composting. The composting process was decrease quickly on the 20 th day, and transfered stability on the 40 th day. The volume of CH4 compost treatment in adding microorganism laboratory of Tunghai University was 35.88 mg/m2/hr, and which was less than adding microorganism of Food Industry Research and Development Institute（50.71 mg/m2/hr）. The decomposition can be expressed by Germination rate, and Paper chromatograph. The treatment of compost in adding microorganism laboratory of Tunghai University had better performance than others. In Germination rate, this treatment of adding microorganism laboratory of Tunghai University was considered 100 % maturity already on 15 th day. The results of growing test for chinese baggage were indicated that fertlilzer 12 % of compost of treatment in adding microorganism laboratory of Tunghai University had better performance on plant weight, plant hight and chlorophyl of chinese baggage.
