Wastes of agriculture and forestry production in our country at present stage is themain processing method in situ piled up or burn, not only waste the resources but alsopollute the environment; Development and utilization of these wastes is not only can solvethe problem of the pollution to the environment, and the treated waste material has goodphysical and chemical properties, can be used as the substrate seedlings and cuttings,realize resource recycling. In agriculture and forestry waste mushroom residue as theresearch object in this paper, through the mushroom residue aerobic composting rottenprocessing, get the following results:1、Looking from the composting temperature, the overall trend of the change oftemperature curve of each process are the same, namely the slow heating and then cooling.The treatment process of mushroom residue the whole rotten maintained at45~55℃high temperature stage; Because this test using the mushroom residue contains some sandand affected by the outside temperature, failed to reach higher temperatures, the processingin the process of rotten experienced more than45℃high temperature, to judge from thetemperature5processing have reached the standard of the rotten.2、The mushroom residue after fermentation rotten to be modified to improve thechemical and physical properties: after each processing mushroom dregs fermented byrotten density increased than before treatment; Total porosity and aeration porositydecreases than before processing, water-holding porosity increases, the size of the voidratio decreases; PH is an alkaline fermentation is increased as before; Cation exchangecapacity (CEC) than before; Mushroom residue rotten process of C/N value, the processingunder the final C/N value in those days, the final C/N ratio values and the initial C/N valueof T value below0.6, that every process has reached the standard of rotten. Rottenchemical properties after the end of the period of improved and more stable chemicalproperties. Rotten as substrate after physical and chemical indicators have reached thestandard, in theory after fermentation process of mushroom residue can be used as asubstrate.3、In rotten after C/N and T value as a reference index of rotten, different moisturecontent and adding the bacterium agent on the result of final rotten difference was notsignificant.
