Problems solved by technology

The laying or sowing of turf on the roof is generally done after the drainage system is handled, and 10-20 cm of soil is laid in advance, and then the turf is laid or the grass seeds are sown; the specific gravity of natural soil is relatively large, generally about one cubic meter per cubic meter. Ton, based on the soil thickness of 15 cm, the area load per square meter is 150 kg, and the total weight of the turf is about 200 kg. To a certain extent, it increases the artificial load-bearing burden on the roof and floor, and aggravates the fatigue of the floor. service life

Abstract

The invention relates to a roof turf matrix with spent mushroom compost of lentinula edodes and biogas slurry as main materials and a preparation method of the roof turf matrix. The roof turf matrix comprises the spent mushroom compost of lentinula edodes, the biogas slurry, bean dregs, clam shell powder, lime powder, light calcium carbonate and ternary compound fertilizer. The invention further relates to the preparation method of the roof turf matrix. According to the roof turf matrix, wood bits or wood chip tissue of the spent mushroom compost of lentinula edodes serves as main materials of basic dry substances, and the bean dregs and the clam shell powder serve as auxiliary materials of the basic dry substances. The waste resources are effectively used. Under the premise that the turf matrix meets the turf growth requirement, the roof turf matrix is low in density and suitable for being laid on roofs of buildings and overcomes the defect that existing turf matrixes are not suitable for being laid on roofs of buildings.

Description

technical field [0001] The invention relates to a roof turf substrate mainly made of shiitake mushroom chaff and biogas slurry and a preparation method thereof, and belongs to the technical field of producing roof turf cultivation substrates by using various agricultural wastes. Background technique [0002] Biogas slurry is rich in nutrients and has good fertilizer effect on crops and plants. However, due to the concentration, large amount, and obvious regionalization of biogas generated by biogas projects, it is difficult to transport and apply biogas slurry, especially for crops. Restrictions of factors such as production cycle and people's level of understanding greatly limit the absorbing capacity of biogas slurry. Therefore, seeking new utilization channels for biogas slurry is one of the tasks we have been working hard on. [0003] The particularity of shiitake mushroom chaff and shiitake mushroom chaff has always been a difficult problem for reuse. For example, the f...
