Embodiment 1

[0028] A sedum plant roof greening matrix, including organic material mixture, perlite, cinder, and broken bricks; the above materials are arranged in layers from top to bottom; the organic material mixture includes compost, peat, diatomite particles, vermiculite , zeolite; compost including brewery filter sludge, sawdust, enoki mushroom residue, urea and superphosphate.

[0029] The preparation method of the organic material mixture is: obtain the beer fresh dehydration filter mud from the beer brewery, divide and take 0.5M 3 , pour into the cement tank, add water 2.5M 3 , stir into a suspension, measure sawdust 2M 3 , Flammulina velutipes waste residue 2M 3 . According to the pre-selected small amount of sludge, sawdust, and Flammulina velutipes mixed with waste residue, the volume air-dry weight is 570kg / M 3 , Weigh urea 13kg, superphosphate 77kg. Add urea to the sludge water and stir to dissolve the sludge. Sawdust and Flammulina velutipes wastes are piled up in a pi...

Embodiment 2

[0031] This embodiment is to plan to plant 100M 2 For the roof of the sedum plant, after the roof waterproofing and the root layer are completed, and before the substrate layer is prepared for construction, the materials in Example 1 are transported to the roof greening site. 4M 3 Spread the broken bricks evenly, and then spread cinders on it until the overall thickness of the broken bricks and cinders is 5cm. Because part of the cinders enter the broken brick layer, the amount of cinders is about 2.5M 3 . After the cinder is laid, a 2cm thick perlite layer is laid on it, and the amount of perlite is about 2.5M 3 . Finally, lay the organic material mixture on the perlite layer with a thickness of 5cm, and the amount of organic material mixture is about 5M 3 . After the laying is completed, use the spraying method to water the substrate layer thoroughly, and water it thoroughly again on the 4th day when the weather is not rainy. Since the construction of the matrix layer ...

Abstract

The invention belongs to the field of growing matrixes of plants, and mainly relates to a red-spotted stonecrop plant roof greening matrix and a preparing method thereof. The red-spotted stonecrop plant roof greening matrix is characterized in that the red-spotted stonecrop plant roof greening matrix is prepared from, by volume, 15-20 parts of organic mixture, 3-5 parts of perlite, 5-10 parts of coal cinder and 15-20 parts of brick rubbles, and the layering preparation method is adopted; the organic mixture comprises compost, peat, kieselguhr particles, vermiculite and zeolite. The red-spotted stonecrop plant roof greening matrix and the preparing method thereof have the advantages that the nutritional conditions of an organic material layer are rich, high water permeation and gas permeability are achieved, and a moisture and fertilizer preserving function is achieved; the plant adverse resistance and the stability of a planting system can be improved, and the effect of guaranteeing the long-term stability of the planting system and a good rainwater damming function are achieved.

Description

technical field [0001] The invention belongs to the field of plant growth substrates, and mainly relates to a sedum plant roof greening substrate and a preparation method thereof. Background technique [0002] Nutrient characteristics such as organic matter and nutrients of the cultivation substrate are the key factors that determine the growth of plants. For general herbaceous flowers and vegetable cultivation, the plant growth period is short and the growth rate is fast, requiring a high level of cultivation substrate fertility. Our years of research on flower cultivation substrates have shown that for short-term cultivation of flowers such as grass flowers, when the organic matter content of the cultivation substrate is at the level of 200-300g / kg, the corresponding nutrient levels such as nitrogen, phosphorus and potassium are also relatively high, and the plants grow vigorously and the cultivation effect is good. . However, for the plant cultivation of light roof gree...
