Study on the effect of mushroom residue on micro-ecology of soil
The batch experiments were carried out to investigate the improvement of mushroom residue to soil quality and the action mechanism.In the experiment, mushroom residue with different mass concentration (0, 1.5 ％, 3.0％ and 4.5％) was cultured in soil, the number of various types of micro-organisms and the activity of certain enzymes in different soil samples were detected regularly.Results showed that the addition of mushroom residue could increase the number of micro-organisms and the activity of soil enzymes, among them,the amount of actinomycetes, fungus and the activity of chitinase, dehydrogenase were increased with the increasing of mushroom residue adding quantity.This indicated that mushroom residue could expand the scale of microflora in soil and further improve the soil quality fundamentally; it could also enhance soil disease suppression ability simultaneously.When the addition amount of mushroom residue was 4.5％, the average increase of actinomycetes, fungus quantity and chitinase, dehydrogenase activity were 1 399.00％, 2 773.33％, 1 309.36％, 2 512.29％.
