The invention discloses a novel substrate for simple roof
greening by applying
greening wastes and a preparation method thereof. The novel substrate for simple roof
greening is prepared from greeningwaste decomposed
compost, grass carbon,
volcanic rock and
vermiculite. The preparation method comprises the following steps: selecting the greening waste decomposed
compost with a particle size of less than 5 mm, and mixing the greening waste decomposed
compost with the grass carbon, the
volcanic rock and the
vermiculite according to a volume ratio of (40-70%): (0-25%): (18-36%): (12-24%). The novel substrate provided by the invention fully utilizes
nutrient supply properties of the greening wastes, water-retaining and
nutrient-retaining properties of the
vermiculite and stability and root-fixing properties of the
volcanic rock, provides good growth conditions for a
plant in the aspects of water, nutrients, air and heat, and meets the needs of simple roof greening for plantation and growthof the
plant; meanwhile, physical and
chemical property indexes of the substrate all meet the requirements of simple roof greening; and the novel substrate provided by the invention replaces a grasscarbon substrate with
urban greening wastes, so waste is turned into treasure; a novel way for treatment of the
urban greening wastes is opened up; the usage amount of grass carbon resources is reduced; the cost of the substrate is lowered; and
sustainable development of resources and the environment can be easily realized.
