NOVELTY - A non-ground vertical planting organic composite substrate manufacturing method involves weighing 2-3 pts. wt. peat, 2-3 pts. wt. rice coal slag, 3-5 pts. wt. agriculture organic waste mixture material fermented grain, 1-2 pts. wt. coconut husk fiber and compound fertilizer to obtain matrix formula, taking bagasse and corn core, adding mushroom residue and straw powder, carrying out bio-fermentation for 25-50 days, drying, crushing, adding 1-2 kg of 30 wt.% humic acid, taking rice husk, pressing, carbonizing, crushing, sieving to obtain rice coal slag, taking cassava residue, and standing.    USE - Non-ground vertical planting organic composite substrate manufacturing method (claimed).    ADVANTAGE - The substrate has loose texture, light specific gravity and high nutrient content. It is suitable urban arterial road guardrail, bridge and other non-solid green ground.    DETAILED DESCRIPTION - A non-ground vertical planting organic composite substrate manufacturing method comprises weighing 2-3 pts. wt. peat, 2-3 pts. wt. rice coal slag, 3-5 pts. wt. agriculture organic waste mixture material fermented grain, 1-2 pts. wt. coconut husk fiber and compound fertilizer to obtain matrix formula, taking bagasse and corn core, adding mushroom residue and straw powder, carrying out bio-fermentation for 25-50 days, drying, crushing, adding 1-2 kg of 30 wt.% humic acid, taking rice husk, pressing, carbonizing, crushing, sieving to obtain rice coal slag, taking cassava residue, standing, selecting crop straw, tea branches and vegetable vine, drying, crushing, adjusting pH value, carbon/nitrogen, electrical Conductivity value and water content index, adding water, stirring, stacking, composting, adding high temperature decomposing inoculant 2 times a day, mixing, measuring temperature, turning once at not less than 55 degrees C, or 1-3 times a day at 68-70 degrees C, drying, crushing, sieving to obtain agriculture organic waste mixture material fermented grain, taking raw materials, drying, crushing, sieving, stirring, using woven bag, weighing, package, sealing, and storing.
