Embodiment 1
[0046] A special substrate for sponge city greening, which is composed of mushroom dregs, vinegar dregs, cassava dregs fermented materials, medium and coarse sand, carbonized chaff or plant ash, coconut peat and soil. The substrate raw materials are uniformly mixed in a certain proportion after pretreatment Stir, then sieve and package to form a soil product with sponge properties; it consists of 5 parts by volume of fermentation materials of mushroom dregs, vinegar dregs, and cassava dregs, 4 parts of medium coarse sand, carbonized chaff or plant ash 2 parts, 4 parts of coconut peat, 3 parts of soil.
[0047] The general requirements for the basic characteristics of the matrix are:
[0048] a) have excellent plant root adaptability;
[0049] b) The product is lightweight but does not scatter dust like soil, has excellent water absorption performance, and exhibits a sponge-like elastic body structure after absorbing water;
[0050] c) The product has good drainage performanc...
