Problems solved by technology

[0007] The traditional roof greening cultivation substrate contains a large amount of garden soil and peat and other materials, which has a high bulk density, which increases the load burden on the building roof; and peat, peat and other materials have high organic matter content, which will easily cause a large amount of organic components to decompose in the later stage of use, resulting in the subsidence of the substrate , subsidence and other problems affect the service life of the matrix, and the matrix material needs to be replaced frequently
At the same time, it will also add a lot of difficulty to maintenance management, which also increases management costs and is not conducive to the sustainable development of roof greening.

Embodiment 1

[0075] 1. Preparation of landscaping waste compost

[0076]1A) collect the landscaping wastes of urban garden plants littered in autumn, and pulverize to a particle size of about 1-2cm (usually 1-2cm, preferably about 1.5cm);

[0077] Landscaping waste can be selected from one or more of branches, bark, grass clippings, spent flowers, and fallen leaves, all of which are suitable for the present invention, among which the fallen leaves and small branches of urban garden plants in autumn are preferred. In addition to selecting fallen leaves and small branches of urban garden plants in autumn, other landscaping wastes in the field are suitable for the present invention. For example, the littered leaves and small branches of common urban garden plants in northern regions such as poplar and willow are selected, which is conducive to the complete decomposition of compost products and is more suitable for the special purpose of roof greening.

[0078] 1B) Add water to the crushed la...

Embodiment 2

[0102] 1. Preparation of landscaping waste compost

[0103] Except that the water content of the landscaping waste compost is 9%, the others are the same as in Example 1.

[0104] 2. Except that the mass ratio of perlite with a particle size of 1-3.35mm and 0.2-1mm is 8:2, the rest is the same as in Example 1.

[0105] 3. The rest is the same as in Example 1 except that the fresh vinegar residue is rinsed with distilled water until the pH of the rinse solution is 6.5, and air-dried to a moisture content of 3%.

[0106] 4. Evenly mix the raw material perlite, landscaping waste compost, vinegar residue and polyethylene glycol to obtain the special cultivation substrate for roof greening of the present invention, wherein perlite, landscaping waste compost, vinegar residue and polyethylene glycol The weight proportion of alcohol is:

[0107]

[0108] The test results of the performance indexes of the prepared cultivation substrate are shown in Tables 1, 2 and 3.

Embodiment 3

[0110] 1. Preparation of landscaping waste compost

[0111] Except that the water content of the landscaping waste compost is 5%, the rest are the same as in Example 1.

[0112] 2. Except that the mass ratio of perlite with a particle size of 1-3.35mm and 0.2-1mm is 6:4, the rest is the same as that of Example 1.

[0113] 3. The rest is the same as in Example 1, except that the fresh vinegar residue is rinsed with distilled water until the pH of the rinse solution is 5.5, and air-dried to a moisture content of 1%.

[0114] 4. Evenly mix the raw material perlite, landscaping waste compost, vinegar residue and polyethylene glycol to obtain the special cultivation substrate for roof greening of the present invention, wherein perlite, landscaping waste compost, vinegar residue and polyethylene glycol The weight proportion of alcohol is:

[0115]

[0116] The test results of the performance indexes of the prepared cultivation substrate are shown in Tables 1, 2 and 3.

Abstract

The invention discloses a culture medium for roof greening and a preparation method thereof. The culture medium is made from perlite, garden greening waste compost, vinegar residues and polyethylene glycol. The culture medium has the advantages that the culture medium special for roof greening is made from a main material and main additives, wherein the main material is the perlite, and the additives include the garden greening waste compost and the vinegar residues, so that the survival and growth needs of roof plants can be met, waste of garden greening and the vinegar industry is fully utilized, waste resources are utilized integrally, the production cost is reduced, and the waste resources are recycled; the culture medium is beneficial to the sustainable development of urban ecologicalenvironments.

Description

technical field [0001] The invention relates to a utilization method of landscaping waste and vinegar industrial waste, in particular to a method for preparing a special cultivation substrate for roof greening by utilizing landscaping waste compost and vinegar residue of vinegar industry waste and the prepared special cultivation substrate for roof greening. Background technique [0002] With the rapid improvement of the social and economic level, the urban population is increasing day by day, and urban commercialization activities are also increasing, resulting in the deterioration of the ecological environment of most cities in my country, and frequent occurrence of severe weather phenomena such as smog and dust. In North China, where the Beijing-Tianjin-Hebei region dominates, the deterioration of the ecological environment is particularly serious. With the increasingly prominent urban ecological problems in our country, more and more industries have begun to explore solu...
