The invention discloses a composition for digesting allelochemicals in semi-substrate covering raw materials and a using method of the composition, and belongs to the field of garden
engineering. Thecomposition comprises ground
bark particles and a broad-spectrum
microorganism combined composting substance. The using method comprises the following steps: S1,
nutrient soil is laid on a bottom layer, and
plant fibers, a
nutrient substance and an original bacterium solution are sequentially added on the surface of the
nutrient soil from top to bottom; S2, operators gather the nutrient soil and the composition into a long strip-shaped gathering
pile with a width of 1-2.5 m and a height of 1.5-2 m, meanwhile, air-permeable coverage is carried out on the surface of the gathered object, and semi-
corrosion treatment is carried out; S3, the operators control the semi-
corrosion treatment temperature to be 43-52 DEG C; and S4, the operators replace the surface of the gathered object by a closedcover,
decomposition treatment is carried out, and the temperature is controlled to be 60-65 DEG C in the
decomposition process. According to the technical scheme, broad-spectrum microorganisms are used for
decomposition, so that tree
bark is prevented from generating an uncoupling agent, and the damage to
plant roots is avoided.
