Problems solved by technology

Landscaping waste is usually mainly disposed of through incineration and landfill, which not only pollutes the environment, but also causes waste of potential resources
At the same time, in the process of urban sewage treatment, a large amount of sludge is also produced. The current main treatment methods are landfill or incineration, but neither is the best form of resource conversion and utilization.
[0007] In the prior art, there is no literature on the mixed composting of landscaping waste and domestic sludge, the two main urban organic wastes, and no further research on the use of them as roof greening cultivation substrates.

Embodiment 1

[0033] The mixed medium for the cultivation of S. japonica provided in this example is formed by mixing prefabricated decomposed compost and perlite, wherein the mixing volume ratio of decomposed compost and perlite is 5:(1-5).

[0034] The prefabricated decomposed compost is made by mixing landscaping waste and domestic sludge and then decomposing. The volume ratio of landscaping waste and domestic sludge is 6:5.

[0035] Among them, landscaping waste is sterilized and pulverized into granular particles with a particle size less than or equal to 5 mm; landscaping waste is one or more of dead branches, fallen leaves, grass clippings, flower rot, tree and shrub pruning, and plant residues. variety, or other plant waste.

[0036] The main physical and chemical performance indicators of the mixed matrix are: the pH value is 6.8; the conductivity is 1.162.7uS / cm; the bulk density is 0.6g / cm 3 60.5% total porosity; 28.4% ventilating voids; 32.1% water-holding voids; 53.4% ​​organi...

Embodiment 2

[0048] The S. japonica cultivation mixed substrate and preparation method thereof provided in this embodiment, its raw material components and steps are all basically the same as in Example 1, the difference is that:

[0049] (1) Prepare raw materials:

[0050] Prepare decomposed compost raw material and perlite, the mixing volume ratio of decomposed compost raw material and perlite is 5:1;

[0051] (2) Composting treatment:

[0052] Before composting, the landscaping waste is treated with a pulverizer into particles with a particle size less than or equal to 5 mm. According to the basic physical and chemical properties of the landscaping waste and domestic sludge, the landscaping waste and domestic sludge are mixed in a weight ratio of 6: Put the ratio of 5 into the agitator and stir evenly, adjust the initial carbon-nitrogen ratio of the composting raw materials to be controlled at (16-25):1, and the moisture content to be controlled at 60%. Aerobic composting is carried ou...

Embodiment 3

[0060] The S. japonica cultivation mixed substrate and preparation method thereof provided in this embodiment, its raw material components and steps are basically the same as those in Examples 1 and 2, the difference being that:

[0061] (1) Prepare raw materials:

[0062] Prepare decomposed compost raw materials and perlite, the mixing volume ratio of decomposed compost raw materials and perlite is 1:1;

[0063] (2) Composting treatment:

[0064] Before composting, the landscaping waste is treated with a pulverizer into particles with a particle size less than or equal to 5 mm. According to the basic physical and chemical properties of the landscaping waste and domestic sludge, the landscaping waste and domestic sludge are mixed in a weight ratio of 6: Put the ratio of 5 into the agitator and stir evenly, adjust the initial carbon-nitrogen ratio of the composting raw materials to be controlled at (16-25):1, and the moisture content to be controlled at 60%.

Abstract

The invention discloses a mixed substrate for cultivation of Sedum lineare. The mixed substrate is prepared by mixing prefabricated decomposed compost and perlite, and the volume proportion of mixture of decomposed compost and perlite is 5:1. The pH value of the mixed substrate is 6.8, conductivity is 1.162.7uS / cm, unit weight is 0.6g / cm<3>, total porosity is 60.5%, ventilation gap is 28.4%, water-holding pore is 32.1%, organic matter is 53.4%, nitrogen is 2.5%, and phosphor is 0.7%. The invention also discloses a preparation method of the mixed substrate for cultivation of Sedum lineare. Urban garden greening waste and waste life sludge are mixed, decomposed compost and perlite are prepared for roof greening cultivation substrate, the substrate is suitable for roof growth of Sedum lineare with good cultivation effects; unit weight, porosity, contents of organic matters, nitrogen and phosphor and other characteristics satisfy requirements of roof greening cultivation medium, average branch length, leaf number, leaf width, leaf area and other growth vigor indices of cultivated Sedum lineare are obviously better than the indices of Sedum lineare cultivated by peat substrate and garden soil substrate, and the cultivation effects are good.

Description

technical field [0001] The invention relates to a mixed substrate for plant cultivation, in particular to a mixed substrate for the cultivation of sageria and a preparation method thereof. Background technique [0002] Modern cities are densely covered with high-rise buildings and the heat island phenomenon is serious, so there is an urgent need for three-dimensional greening, especially roof greening, which is currently an important environmental protection project being promoted by governments all over the world. [0003] Due to its environmental characteristics, the roof of a building is generally only suitable for planting some perennial herbaceous plants with shallow roots, so as not to damage the roof waterproof structure. In addition, due to the special environment such as long sunshine and high temperature on the roof, it is necessary to plant plants with strong heat resistance, drought resistance and certain cold resistance. [0004] At present, the commonly used r...
