However, It also generates a lot of environmental problems in soil and atmosphere. This study used the fresh chicken manure for the main materials, adding and mixing the different adjustment materials, such as sawdust, reflow bacterium and mushroom cultivation waste bags. Adjust the initial carbon-nitrogen ratio to about 11 and analyze the Ferment mixture in physics, chemistry and the biological. In the variation of temperature, moisture content, pH, C/N and germination ratio, showed that the regulation above 45℃ high temperature with compost D (mixed by mushroom cultivation waste bags) for 16 days, the PH of all the compost was alkaline. And the variation in carbon-nitrogen ratio (C/N) was lower than initial but still above 10, was comply with the C/N standard. The study results show that, the compost for mixed by sawdust, reflow bacterium and mushroom cultivation waste bags, even though the initial C/N less than 25 to 30, the composting still could be complete. The pot experiment used the compost D for plant food, which was the best of the result of seed-germination percentage test. The report showed the grain yield will be higher with the plant food increase, but the 2DF (double of the recommended conventional nitrogen application) was not significantly higher than the 4DF (quadruple of the recommended conventional nitrogen application).
