Problems solved by technology

In recent years, some lighter roof greening substrates have appeared, but it is still necessary to lay a thicker soil layer to maintain plant growth, which is relatively heavy; in addition, the ability to retain fertilizer and water is irrational, easy to harden, and is not resistant to trampling. The problem of difficult maintenance has not been solved well

Abstract

The invention discloses light-weight nutrient soil used for roof greening. The light-weight nutrient soil comprises the following raw materials in parts by weight: 25-38 parts of an organic fertilizer, 13-22 parts of vinasse, 3-7 parts of chitosan, 10-20 parts of biogas residue, 2-6 parts of bone meal, 11-23 parts of zeolite powder, 15-23 parts of decomposed bean curd residues, 13-26 parts of attapulgite clay, 10-20 parts of leaf mould, 0.3-0.8 parts of starch-grafted acrylate, 1-2 parts of a loosener, 2-3 parts of a plant nutrition agent, 0.1-0.5 parts of citric acid, 0.2-0.6 parts of aspirin, 0.1-0.4 parts of alpha-naphthylacetic sodium salt, 1-3 parts of a microbe fertilizer, 2-3 parts of an inorganic fertilizer, and 0.5-1 part of ginger. The light-weight nutrient soil used for roof greening has the advantages of light loading, low unit weight, no soil hardening, trampling resistance, good water retention and fertilizer conservation performances, no pollution, and low cost, and is suitable for popularization.

Description

technical field [0001] The invention belongs to the technical field of nutrient soil, and in particular relates to a lightweight nutrient soil for roof greening and a preparation method thereof. Background technique [0002] With the increase of urban density and multi-layered buildings, urban greening develops into three-dimensional space, expands green space, and expands a form of greening and beautifying urban multi-dimensional natural factors. Roof greening mainly brings huge environmental benefits and economic benefits to cities in terms of alleviating the urban heat island effect, improving energy-saving benefits of buildings, reducing the load on urban rainwater treatment systems, improving urban landscapes, and enriching urban species diversity. However, what needs to be considered in roof greening is the load-bearing issue of the roof. Because it is not grounded, the water and fertilizer retention of the nutrient soil used must also be considered. Therefore, the nut...
