Abstract

The invention discloses a roof greening substrate and a preparation method thereof, and relates to the technical field of flower planting. The substrate is prepared from the following raw materials: perlite, vermiculite, biogas residue, tea leaf residue, cassava residue, biosynthesis turf, straw, greening waste, chicken manure, cow dung and inorganic fertilizer; the preparation method comprises the following steps: (1) preparing a first fermented material; (2) performing decomposition promoting reaction to obtain a decomposed material; (3) adding a functional fungicide for co-fermentation to prepare the green roofing substrate. The roof greening substrate of the invention has the advantages of light weight, good breathability and water-holding property, rich nutrition, high environmental protection degree and cyclic utilization.

Description

technical field [0001] The invention relates to the technical field of flower planting, in particular to a roof greening substrate and a preparation method thereof. Background technique [0002] One of the trends in the development of modern architecture is to coordinate the building with the natural environment and introduce more green space into the building space. In this context, green roofs have been paid more and more attention. The efficacy of roof greening technology is manifested in many aspects, which can be roughly summarized as follows: (1) Alleviate the urban heat island effect and adjust the urban climate; (2) Roof plants can absorb toxic gases such as sulfur dioxide and nitrogen oxides, Retain dust and purify urban air; (3) Alleviate the "dry island effect" of the city. Green roofs can store precipitation in the matrix or be absorbed by plants. Through the transpiration of plants and the evaporation of soil matrix, the moisture in the urban air will increase....
