Embodiment 1

[0016] A roof greening substrate provided by the present invention is mainly composed of two parts, including a core substrate and an auxiliary substrate, and the core substrate includes sludge composting products, garden Waste fiber and water retention agent, the auxiliary matrix includes vermiculite and perlite, wherein the weight ratio between the total weight of the core matrix and the vermiculite and perlite is 68-82:3-7:15-25 . Preferably, the auxiliary substrate also includes landscaping soil.

[0017] The greening matrix in this embodiment includes 35 parts by weight of sludge composting products, 65 parts by weight of garden waste fibers and 1.2 parts by weight of water retaining agent.

[0018] Among them: sludge composting products are the products of domestic sludge fermentation in cities. Among them, the water content of the fermented sludge is below 15%, and the heavy metal content is within the national standard range. It is light in weight and plays the role...

Embodiment 2

[0027] Further, the present invention also provides a roof greening method, the roof greening method comprising the following steps: A, weighing the sludge compost product, garden waste fiber and water retaining agent in a weight ratio of 35-43:55-65:1-1.2 , forming a core matrix mixture; B, stirring the core matrix mixture evenly, grinding and granulating to form a core matrix with an average particle size of 1 to 6 mm; C, granulating the core matrix in step B, and Vermiculite and perlite are mixed according to the weight ratio of 68~82:3~7:15~25 to form a greening matrix; the greening matrix is ​​evenly spread in the roof planting area to be greened, and according to the plants to be planted, select the laying Thickness; E. After raking and compacting the green substrate, plant green plants. Preferably, in the sludge composting product, the water content of the fermented sludge is below 15%

[0028] Specifically, in a roof greening project in this embodiment, the following ...

Abstract

The invention relates to a novel roof greening matrix and a roof greening method. The greening matrix comprises a core matrix and an auxiliary matrix, wherein the core matrix comprises a sludge compost product, garden waste fibers and a water retaining agent according to the weight ratio of (35-43):(55-65):(1-1.2); the auxiliary matrix comprises vermiculite and perlite; a ratio of the total weight of the core matrix to the weight of the vermiculite to the weight of the perlite is (68-82):(3-7):(15-25). The matrix provided by the invention can meet a roof greening soil utilization requirement, and sludge of a sewage treatment plant and garden waste can be effectively eliminated, and the aim of resource circulation is fulfilled; meanwhile, the greening matrix is light in material weight; raw materials are readily available; the cost is low; the fertilizer and water retaining effect is good; finally, the matrix is changed from a conventional state into a granular state, so that the problem of matrix loss can be effectively solved, and a slow release effect can be achieved; the growth of plant roots is facilitated; the specific construction and operation are facilitated; the novel roof greening matrix is suitable for the general popularization in the whole nation.

Description

technical field [0001] The invention relates to a roof greening technology, in particular to a roof greening substrate and a roof greening method. Background technique [0002] One of the trends in the development of modern architecture is to coordinate the building with the natural environment and introduce more green space into the building space. In this context, green roofs have been paid more and more attention. [0003] The effect of roof greening technology is manifested in many aspects, which can be roughly summarized as follows: (1) Alleviate the urban heat island effect and adjust the urban climate; (2) Roof plants can absorb toxic gases such as sulfur dioxide and nitrogen oxides, and retain dust , to purify the air in the city; (3) to alleviate the "dry island effect" of the city; the "dry island effect" of the city means that the relative humidity of the city is smaller than that of the suburbs; Evaporation of the soil matrix increases the moisture in the urban...
