Light cultivation substrate for wall greening and preparation method thereof

Abstract

The invention relates to a plant cultivation substrate, and discloses a light cultivation substrate for wall greening and a preparation method thereof. The light cultivation substrate for wall greening comprises moss and perlite in a volume ratio of 1-2:1-2. The preparation method comprises steps of: conducting a swelling treatment on perlite to obtain granular pearlite; washing and drying moss and the granular pearlite; and uniformly mixing the two to obtain the light cultivation substrate for wall greening. According to the invention, the light cultivation substrate for wall greening has advantages of simple preparation, light weight, strong water retaining capacity and good permeability, and can reduce the load of wall if applied to the wall; meanwhile, the components have extensive sources and low price, so as to reduce the cost of the prepared cultivation substrate. The preparation method provided by the invention has simple process and convenient operation.

Description

technical field [0001] The invention belongs to the field of landscaping and relates to a plant cultivation substrate, in particular to a light-weight cultivation substrate for wall greening and a preparation method thereof. Background technique [0002] With the acceleration of urbanization, in order to improve the ecological environment of large-scale cities with scarce land resources, technologies such as wall greening and roof greening have become common greening measures. When carrying out large-scale plant cultivation on the wall, a cultivation base with a cultivation substrate can be provided in order to allow the plants to take root. The cultivation substrate is not only a carrier for plant roots to attach to, but also an important channel for providing water, nutrients and air to plants. Therefore, in order to promote the growth of plants, the bulk density, total porosity, water retention and air permeability of the cultivation substrate should meet the requirement...
