Abstract:: Taking culture material of edible mushroom as material,with new environmental protection disinfectant CTP-3:the disinfection effect of 100%，50%，25%，10%，5%，2.5% six concentration gradient,and 30，60，90，120，150，180，210，240，270，300 s microwave respectively on most common miscellaneous bacteria (escherichia coli，bacillus subtilis，wood mould) in mushroom growing substrate were studied.One of the most difficult to remove of the bacteria use microwave and disinfectant work together.Then its sterilization effect was observated.The results showed that when disinfection function，bacillus subtilis had growth in 25% diluted disinfectant，escherichia coli and wooden mold had growth in 10% diluted of disinfectant.And when microwave function,escherichia was killed all after 240 s microwave，wooden mold was dead after 210 s microwave，but bacillus subtilis was killed after 270 s microwave，so bacillus subtilis was the most difficult competitor to kill completely;when disinfectant diluted 10% role，and microwave processing 180 s were the best combination to kill all miscellaneous bacteria.
