Heavy metal degrading soil conditioner

The invention relates to the technical field of soil improvement, in particular to a heavy metal degrading soil conditioner. In allusion to the problems that the conventional soil conditioner is relatively narrow in application range, has low effective component content and low effective component extracting rate, easily causes resource waste and does not have an excellent heavy metal degrading effect, the invention provides the scheme as follows: the heavy metal degrading soil conditioner comprises the following raw materials in percent: 25-40% of an organic fertilizer obtained by thoroughly decomposing bamboo and wood leftovers, 15-25% of an alga fertilizer, 20-30% of medical stone, 3-8% of EM compound bacteria, 3-10% of shale opal, 2-7% of phosphorus ore powder, 5-15% of furfural residue and 5-10% of fly ash. The heavy metal degrading soil conditioner is excellent in improvement effect of degrading heavy metal contaminated soil and wide in application range; the effective component content is high, and fur
