AI Technical Summary

Problems solved by technology

The conventional substrate layer is mostly made of garden soil, clay soil, etc., and has the following disadvantages: large volume, poor water and fertilizer retention, poor structure, etc.
These problems greatly limit the application and development of slope greening
[0007] At present, in roof greening at home and abroad, the planting layer is mainly made by mixing materials and laying them manually. Some materials are restricted by region, which is not conducive to large-scale application.

example 1

[0019] Location: Shanghai, steep roof, slope 6-44 degrees, construction in March 2010.

Embodiment approach

[0020] Implementation method: a combination of aggregate spraying and roof greening auxiliary measures.

[0021] The material ratio is as follows:

[0022] Clay soil: 0.9m3; organic matter: 0.9 m3

[0023] Vermiculite: 1.35 m3; Perlite: 0.9 m3

[0024] Plant fiber: 0.45 m3; soil additive: 0.036 m3

[0025] Slow-release fertilizer: 0.06 m3; clear water 1.2 m3;

[0026] The preparation process of soil culture medium for slope roof greening of the present invention is as follows:

[0027] First, pour clean water into the silo of the sprinkler, then add clay soil, organic matter additives, vermiculite, perlite, plant fiber and slow-release fertilizer into the silo for stirring. The prepared soil additive is stirred while adding to make it fully react with the soil; after the reaction, spray the prepared soil medium on the sloped roof.

[0028] After the above work is completed, artificial planting is carried out according to the design requirements.

[0029] The soil add...

Abstract

The invention relates to a soil culture medium for greening of a slope roof, which is characterized by comprising the following materials by weight part: 18-22 parts of clay soil, 20-25 parts of organic material additive, 30-35 parts of vermiculite, 23-25 parts of perlite, 11-14 parts of plant fiber, 1-2 parts of controlled release fertilizer, 0.8-1 parts of soil additive, and 45-48 parts of clear water. A spraying seeding machine is adopted to spray the prepared soil culture medium on the slope roof. The soil culture medium has the advantages that with the application of the soil additive, soil particles can be combined together tightly and effectively, so that the adsorption capability of soil is improved, the capability of the soil culture medium resisting rain wash is enhanced, and a matrix carrier capable of being permanently immobilized is provided for green plants of the slope roof.

Description

technical field [0001] The invention relates to a soil culture medium for slope roof greening, which is especially suitable for greening steep slope roofs. Background technique [0002] CN 101194586 discloses an ecological nutrient soil for roof greening, which is composed of sewage sludge, perlite, loess, slow-release, sawdust, bagasse, rock, water-retaining agent, beneficial microbial flora, and non-metallic minerals. The above materials are mixed in proportion, stirred with water, covered with a plastic film, and stacked and degreased for 25-30 days at 60-90°C. [0003] CN 1460408A discloses a long-acting light substrate formula for roof greening, which is a light-weight roof greening planting substrate mainly composed of waste materials. The substrate components and proportions are: peat soil 40-45%, sawdust 10-15%, coconut Bran 8-10%, perlite 3-4%, ceramsite 4-5%, yellow loam 18-20%, long-acting compound slow-release fertilizer 0.18-1%, a small amount of water retainin...
