Garden type roof greening matrix and manufacturing method thereof

Abstract

The invention belongs to the technical field of plant growth matrices, and particularly relates to a garden type roof greening matrix and a manufacturing method thereof. The garden type roof greeningmatrix comprises an organic matter and an inorganic matter, wherein the volume percentage of the inorganic matter is 80%-85%; the volume percentage of the organic matter is 15%-20%; in the inorganic matter, the weight percentage of crushed particles with the particle size of 0.05 cm to 0.5 cm is 15-65%; and in the organic matter, the weight percentage of crushed particles with the size of 0.05 cmto 0.5 cm is 15-65%. The garden type roof greening matrix provided by the invention mainly meets the requirements of high-grade three-dimensional greening, can be intelligently managed aiming at the construction and management of gardens with multiple plant types and multi-layer structures and gardens in the air, and high roof load is required. The roof planting with dense plants and a multi-layerstructure can be met, the roof is light in weight, water and fertilizer can be preserved, roots can be easily inserted, permeable drainage is facilitated, water and oxygen can be preserved, roof plants grow reasonably, and green ecological materials are provided for ecological city construction, sponge city construction and fourth-generation residential construction in the future.

Description

technical field [0001] The invention belongs to the technical field of plant growth substrates, and specifically relates to a garden-type roof greening substrate and a manufacturing method thereof, which are mainly used as special substrates required for planting high-density and multi-layered plants on the roof. Background technique [0002] Roof greening is a kind of special space greening of various buildings that are mainly on the roof, such as balconies, terraces, roofs, and interlayers, which are separated from the natural soil. It is a greening activity on the roofs or roofs of various buildings and their structures. The history of roof greening in China is only about ten years old, and most of them are mainly based on landscape design and plant cultivation and maintenance research. The research on roof greening substrates is not in-depth, so that loess or peat are directly used as roof greening substrates. The amount of organic matter is too high to cause excessive s...

AI Technical Summary

Problems solved by technology

Moreover, roof greening also has adverse effects caused by raw material problems, such as: using loess directly as a roof greening substrate, its bulk density is large, and the roof is overloaded; using peat directly as a roof greening substrate is easily crushed and lost, which is affected The environmental conditions are limited; peat moss is not easy to wet when the water content is lower than 40%, and it is difficult to water, resulting in a waste of manpower and material resources

[0004] In addition, the existing standards for roof greening substrates are different. The substrates are not divided into the thickness of the soil layer, and one substrate is uniformly used for vegetation types, resulting in poor roof greening effects.
