Problems solved by technology

Peat is produced in the Northeast, where resources are scarce and cannot be regenerated. The cost of using peat outside the Northeast is very high; although yellow loam can provide certain nutrients, too much yellow loam increases the proportion of the substrate and increases the load-bearing capacity of the roof. Certain disadvantages
In addition, bulky substrates are bulky and expensive to transport, which is also a disadvantage

Abstract

The invention discloses a light compound substrate special for roof greening and a preparation method and using method thereof. The compound substrate is mainly composed of, by volume, 20%-30% of coconut residues, 20%-25% of wheat straw, 12%-20% of corn stalks, 10%-15% of withered branches and leaves, 10%-15% of vermiculite, 5%-15% of ash residues and 3%-10% of river sand. According to the light compound substrate special for roof greening, the mass is small, the light requirement is met, and the roof load is reduced; the higher fertilizer efficiency is achieved, and the physical and chemical properties are suitable for growth of plants; the raw materials mostly come from waste of vegetation carpets, agricultural production and landscaping, the cost is low, and the light compound substrate is a novel compound substrate material suitable for a roof greening engineering project; compared with common bulk substrates, the transportation cost is greatly lowered after the compound substrate is prepared into compressed blocks; use is convenient, the light compound substrate is directly used after being foamed with water without adding other fertilizer, the application range is wide, and the light compound substrate is suitable for usage and popularization.

Description

technical field [0001] The invention belongs to the technical field of roof greening substrates, and in particular relates to a special light-weight composite substrate for roof greening, and also relates to a preparation method and a use method of a special light-weight composite substrate for roof greening. Background technique [0002] Roof greening refers to the planting of trees, shrubs, flowers, lawns, vegetables, and aquatic plants on the top of buildings. The biggest difference from bottom greening is that the planted soil is not connected with the natural soil. It is a form of greening that does not occupy the ground. . With the acceleration of urbanization, natural land resources are replaced by more and more high-rise buildings, roads, squares and other buildings, the rate of green space drops sharply, the urban heat island effect is more obvious, and the living environment in cities is getting worse. In order to increase the area of ​​green space and improve the...
