Wall body greening composite culture substrate and preparation method thereof

Abstract

The invention relates to plant culture substrates, and discloses a wall body greening composite culture substrate and a preparation method thereof. The culture substrate comprises moss, urea formaldehyde foam, vermiculite and perlite, wherein the volume ratio of the moss, the urea formaldehyde foam, the vermiculite and the perlite is 1-4:1-4:1-2:1-2. The preparation method comprises treating the perlite in an expansion mode to obtain granular perlite, cleaning and drying the moss and the granular perlit, and evenly mixing the moss, the granular perlit, the urea formaldehyde foam with the vermiculite to obtain the wall body greening composite culture substrate. According to the wall body greening composite culture substrate and the preparation method of the wall body greening composite culture substrate, the wall body greening composite culture substrate has the advantages of being simple in preparation, light in weight, strong in water retaining capacity, good in breathability and the like, and can reduce load of a wall body when being used for the wall body. Meanwhile, components are wide in sources and low in price, and cost of the prepared culture substrate can be reduced. The preparation of the wall body greening composite culture substrate is simple in process and convenient to operate.

Description

technical field [0001] The invention belongs to the field of landscaping and relates to a plant cultivation substrate, more specifically, to a wall greening composite cultivation substrate 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 requirements ...
