Problems solved by technology

The load-bearing capacity of the roof and high construction and maintenance costs greatly limit the popularity of roof greening
The use of natural soil for roof greening has many disadvantages such as heavy load and high construction cost. The light-weight cultivation substrates that replace soil are mostly researched and applied with light-weight materials such as peat soil, perlite, fly ash, cinder and straw, while the use of moss Leather soil, soil miscellaneous fertilizer, rotting wood, field saponin (Aeschynomene indica), horse thorn (Indigofera pseudotinctoria), horse mulberry (Coriaria sinica) and young stems and leaves of Toricellia angulata to prepare roof greening cultivation substrates, but there are few reports

Embodiment 1

[0028] (1) Collect moss and topsoil connected with moss in the forest as moss crust, pulverize, air-dry, and sieve to make moss crust particles.

[0029] (2) Collect rotten wood with epiphytic fungi, pulverize, air-dry, and sieve to make rotten wood particles.

[0030] (3) Collecting the saponins ( Aeschynomene indica ), Horsethorn ( Indigofera pseudotinctoria ), Ma Sang ( Coriaria sinica ) and toothed sheath wood ( Toricellia angulata ) tender stems and leaves, crushed, air-dried, and made into green manure.

[0031] (4) Harvest the shrubs, dry them in the sun, and stack them into firewood piles. Cover the firewood piles with soil, light the firewood piles from the bottom, and burn them slowly.

[0032] (5) Prepare the cultivation substrate with 40 kg of moss crust soil particles, 15 kg of rotten wood particles, 20 kg of green manure, and 25 kg of soil miscellaneous fertilizer.

Embodiment 2

[0034] Prepare the cultivation substrate with 50 kg of moss crust soil particles, 15 kg of rotten wood particles, 20 kg of green manure, and 15 kg of soil miscellaneous fertilizer. Others are with embodiment 1.

Embodiment 3

[0036] Prepare the cultivation substrate with 45 kg of moss crust soil particles, 15 kg of rotten wood particles, 20 kg of green manure, and 20 kg of soil miscellaneous fertilizer. Others are with embodiment 1.

Abstract

The invention relates to a method for preparing an ecological cultivation matrix for greening roofs. The method comprises the following steps of: (1) preparing moss incrusted soil granules; (2) preparing rotted wood granules; (3) collecting tender stem leaves of aeschynomeneindica, indigoferapseudotinctoria, coriariasinica and toricelliaangulata, crushing, and airing to prepare green manure; (4) preparing farmyard manure; and (5) preparing 40 to 50 percent of moss incrusted soil granules, 15 percent of rotted wood granules, 20 percent of green manure and 15 to 25 percent of farmyard manure ina dry weight ratio, wherein moss incrusted soil is moss in forests and surface oil connected with the moss. According to the method, raw materials are readily available and low in cost, and the method is convenient to popularize and apply. The prepared cultivation matrix is suitable for the growth of green plants of majority of roofs, is environment-friendly and does not have ecological risks.

Description

technical field [0001] The invention relates to the field of roof greening, in particular to a method for preparing an ecological cultivation substrate for roof greening. Background technique [0002] Roof greening is a form of greening that uses plant materials to cover the roof of the platform without occupying the ground. Roof greening can not only increase the urban green coverage rate, beautify the environment, but also reduce the radiant heat from the roof of building materials, weaken the urban "heat island" effect, protect and improve the urban environment, improve the urban ecological system, and promote the sustainable development of the city. One of the key technologies of roof greening is to prepare a suitable cultivation substrate. The load-bearing capacity of the roof and the high construction and maintenance costs greatly limit the popularity of green roofs. The use of natural soil for roof greening has many disadvantages such as heavy load and high construc...
