A pot experiment was conducted to determine the activity of soil enzymes by potassium permanganate titration, sodium thiosulfate titration and visible spectrophotometry, so as to study the effect of fungus bran complex on soil enzyme activity. The results showed that: ①after addition of inorganic fertilizer, fermented chicken manure and fresh fungus chaff or fermented fungus chaff , the activities of CAT, polyphenol oxidase, invertase, URE and PUO (including AKP ALP, ACP, NP) in soil gradually increased; ②addion of the same amount of fresh fertilizer and fermented chicken manure into soil,the effect of fermented fungus chaff was better under treatment of fermented fungus chaff or fermented fungus chaff. In summary, addition of fungus bran complex agent can significantly increase soil enzyme activity, and effect of fermentation fungus bran is better. ; |
