Abstract

The invention relates to water retaining slow-release light nutrient soil for roof greening. The nutrient soil comprises the following raw materials in percent by weight: 10 to 30 percent of peat soil, 5 to 15 percent of foundation aggregate, 5 to 15 percent of cinder ash and desulphurization gypsum powder combined material, 10 to 40 percent of functional matrix, 10 to 30 percent of rotten organic fertilizer, 0 to 10 percent of oilseed residue, 1 to 10 percent of microorganism fertilizer, 10 to 30 percent of inorganic adsorbent, 10 to 30 percent of inorganic mineral powder, 5 to 10 percent of an antiseptic insecticide, 1 to 10 percent of beneficial microorganism combined powder, and 0 to 10 percent of a pH (potential of hydrogen) adjuster. The nutrient soil is easy to get in raw materials and low in cots, can retain water for a long time and slowly release fertility, is stable in physical and chemical properties, realizes ecological self-circulation, is durable for a long time and particularly applied to application of organic planting and greening on roofs of cities and towns.

Description

Technical field [0001] The present invention involves a kind of nutritional soil, especially for a roof greening, water preservation and mitigating lightweight nutritional soil. Background technique [0002] The popular definition of roof greening is all the planting techniques that are separated from ground. Its cover is not only roof planting, but also includes terraces, rooftops, balconies, walls, underground garages, and overpashed bridges.The greening of all kinds of buildings and structures connected to the soil.It is a form of plant material that is compatible with the growth habits according to the characteristics of building roof structure, load and ecological environment conditions on the roof, and builds green landscapes on the top of the building and all special spaces through certain skills.The greening of the roof to increase the area of urban green space, improve the increasingly worse human living environment space, improve the current situation of natural land an...
