The invention discloses a manufacturing method of a non-ground stereo
greening organic
composite substrate, and belongs to the technical field of gardening. The substrate is composed of the following components in parts by weight: 2 to 3 parts of
peat, 2 to 3 parts of
husk coal slag, 3 to 5 parts of potato residues and
agricultural waste mixed material fermented particles, 1 to 2 parts of coco
coir silk, and a little amount of composite
fertilizer, which is added to increase the nutrients. The manufacturing method comprises the following steps:
drying agricultural wastes in the sun,
grinding agricultural wastes into silks with a
diameter not more than 2 mm and a length not more than 25 mm or particles with a particle size not more than 5 mm; then mixing the processed agricultural wastes with potato residues, adding a high temperature aging inoculant containing beneficial microbes, carrying out composting, aging, and
fermentation so as to obtain particles of potato residues and
agricultural waste mixed material; preparing bio-synthesized
peat and
husk coal slag; then adding coco
coir silk and composite
fertilizer, fully stirring and evenly mixing the raw materials and auxiliary materials together, loading the mixture into bags, weighing the bags, and storing the bags in a warehouse. The produced organic
composite substrate has the advantages of fluffy texture, light weight, and rich nutrients, and is very suitable for the non-ground stereo
greening such as arterial street guard bars, skyways, and the like.
