The invention relates to a compound substrate based on building rubbish and garden waste and a preparation method of the compound substrate. After foaming, the building rubbish becomes to be of a light porous structure, then an organic substrate is buried into porous structures as filler in advance to prepare the compound substrate with a certain particle size, in this way, the weight of the compound substrate is decreased greatly, the defects that common building rubbish is too heavy and poor in structural performance are overcome, and with the porous structure, the capacity of water conservation and manure conservation is higher; it is avoided that when organic and inorganic mixing of a mixing substrate is performed, under the effect of the external world (rainwater and irrigation washing), the particle size is small, permeability is poor, and water and soil loss is prone to occurring; the particle size of the granulated substrate can be controlled quantitatively, permeability is good, and water accumulatio
