To achieve the resource utilization of garden waste, in this study, we used waste as main raw material and conducted static composting with high-temperature aerobic treatment forced ventilation by adding appropriate external additives. Our results showed that during process, pH was weakly alkaline, electrical conductivity between 1.42 1.50 mS/cm. The E4/E6 (an important indicator quality or degree condensation aromatization humic acid) gradually decreased, nitrogen, phosphorus, potassium contents increased. germination index rose ultimately exceeded 80%. Treatment (T2) a final C/N ratio 25:1 addition 0.3% bacterial agent resulted highest nutrient content best compost maturity. All indicators met requirements Chinese “Technical Requirements for Urban Landscape Waste Resource Recycling Deep Processing (GB/T 40199-2021)”. When using composite substrate other horticultural substrates planting, membership function executed comprehensive evaluation. V (T2):V (peat):V (vermiculite):V (vermiculite) = 135:135:30:00 optimal lettuce growth quality. In summary, combining products traditional cultivation at specific shows favorable applicative prospects.
