Embodiment 1

[0094] Embodiment 1 prepares fermentation agent

[0095] Inoculate the Aspergillus fumigatus (Aspergillus fumigatus) strain Bfum-5 with the preservation number CGMCC No. 10929 in liquid potato (PDA) medium, shake culture (35°C, 100r / min) for 48h (usually 36-60h), and cultivate During the process, the number of microbial Aspergillus fumigatus (Aspergillus fumigatus) strain Bfum-5 in the culture solution was determined according to the national standard "GB4789.15-2010 Food Safety National Standard Food Microbiology Examination Mold and Yeast Count" method, until the Aspergillus fumigatus in the culture solution The number of Bfum-5 reaches 3.5×10 8 Individuals / mL (usually (2-5)×10 8 individual / mL).

[0096] Liquid PDA medium formula:

[0097]

[0098] The culture medium was sterilized at 121°C for 15 minutes.

[0099] The Aspergillus fumigatus strain Bfum-5 with the preservation number CGMCC No. 10929 is the strain disclosed in the Chinese patent application of the appli...

[0102] 1. Preparation of fermented mushroom dregs-fly ash

[0103] 1A) After crushing the remaining mushroom dregs after harvesting edible fungi, add fly ash, stir evenly, the volume ratio of mushroom dregs and fly ash is 75:25;

[0104] Mushroom dregs usually use fresh mushroom dregs, including Pleurotus eryngii mushroom dregs, shiitake mushroom dregs, Flammulina velutipes mushroom dregs, Pleurotus ostreatus mushroom dregs, etc. The moisture content of mushroom dregs is 50-65%;

[0105] 1B) Then spray water and wood vinegar to the mixed material, adjust the moisture content of the mixed material to 60% (usually 50%-65%, preferably 50-60%), and prepare the pre-fermented mushroom dregs mixed material, wherein, add The amount of wood vinegar liquid per 1m 3 Add 20mL (usually 15-25mL) of wood vinegar to the mixture of mushroom dregs and fly ash;

[0106] The wood vinegar liquid is diluted with water and then sprayed into the mixture, and sprayed evenly.

[0107] 1C) Add the fe...

Abstract

The invention discloses a plant cultivation substrate for roof greening and a preparation method thereof. The preparation method of the substrate comprises the steps of firstly fermenting mushroom residues and fly ash to prepare fermented mushroom residue-fly ash, and then evenly mixing the raw materials fly ash, turf, fermented mushroom residue-fly ash, vermiculite and water. The plant cultivation substrate for roof greening is prepared by taking industrial waste fly ash and agricultural waste mushroom residue as main raw materials, not only can meet the requirement of normal growth of plants, but also fully utilizes agricultural forestry and industrial waste and comprehensively utilizes resources, so that the production cost is reduced, the recycling of agricultural resources is achieved, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to a method for utilizing industrial and agricultural and forestry waste, in particular to a method for preparing a cultivation substrate by using agricultural waste and industrial waste and the prepared cultivation substrate. Background technique [0002] In recent years, many large and medium-sized cities in China have been repeatedly hit by heavy rains, resulting in frequent waterlogging disasters, and the embarrassment of "watching the sea" has frequently occurred, but the price paid for the scene of "watching the sea" in the inner city is many lives and heavy economic losses. . The utilization awareness of rainwater resources in cities in our country is weak, and the utilization rate of natural rainwater resources is extremely low, less than 10%. A large amount of rainwater resources are directly drained, forming a prominent contradiction with the shortage of water resources in our country. In recent years, most cities in my...
