Embodiment 1

[0019] In a roof greening project, the raw materials of the following parts by weight are taken in proportion: garden soil 15, northeast peat soil 20, crude fiber humus 40, perlite 15, vermiculite 5 and organic fertilizer fine powder 5, wherein the raw material All are commercially available. Stir the above raw materials evenly, and then add the insecticide smell dead, the dosage is 8g per cubic meter; the fungicide hymexazol, the dosage is 1.5g per cubic meter, to remove the insect bodies, eggs and harmful bacteria that may exist in the soil; then , add Aisen water-retaining agent, the dosage is 8g per cubic meter; and Shi Kefeng long-acting slow-release compound fertilizer (fertility slow-release agent), the dosage is 75g per cubic meter, and mix well. Then it is bagged and transported to the project site, and the substrate is evenly spread in the compound roof greening planting area. According to the different plant materials, different paving thicknesses are adopted, gener...

Embodiment 2

[0021] In a roof greening project, the raw materials of the following parts by weight are taken in proportion: garden soil 10, northeast peat soil 25, crude fiber humus 35, perlite 20, vermiculite 3 and organic fertilizer fine powder 7, wherein the raw material All are commercially available. Stir the above raw materials evenly, and then add the insecticide smell dead, the dosage is 5g per cubic meter; the fungicide hymexazol, the dosage is 1g per cubic meter, to remove the insect bodies, eggs and harmful bacteria that may exist in the soil; then, Add Aisen water-retaining agent, dosage 5g per cubic meter; and Shi Kefeng long-acting slow-release compound fertilizer (fertility slow-release agent), dosage 60g per cubic meter, mix well. Then it is bagged and transported to the project site, and the substrate is evenly spread in the compound roof greening planting area. According to the different plant materials, different paving thicknesses are adopted, generally more than 40 cm....

Embodiment 3

[0023] In a roof greening project, take the following raw materials in proportion by weight: pastoral soil 20, northeast peat soil 15, crude fiber humus 45, perlite 10, vermiculite 7 and organic fertilizer fine powder 3, wherein the raw material All are commercially available. Stir the above raw materials evenly, and then add the insecticide smell dead, the dosage is 10g per cubic meter; the fungicide hymexazol, the dosage is 2g per cubic meter, to remove the insect bodies, eggs and harmful bacteria that may exist in the soil; then, Add Aisen water-retaining agent, the dosage is 10g per cubic meter; and Shi Kefeng long-acting slow-release compound fertilizer (fertility slow-release agent), dosage is 90g per cubic meter, and mix well. Then it is bagged and transported to the project site, and the substrate is evenly spread in the compound roof greening planting area. According to the different plant materials, different paving thicknesses are adopted, generally more than 40 cm....

Abstract

The invention provides a substrate for double roof greening, which is prepared from the raw materials of natural soil, Northeastern turfy soil, coarse fiber humus, perlite, vermiculite, organic fertilizer flavor powder and the like by scientific proportioning and is simultaneously subjected to high technical treatments of insect prevention, disease prevention, moisture preservation and fertility slow release. The special substrate for the double roof greening is light in weight with the weight per cubic meter of no more than 550kg and saturated water weight of no more than 900kg, thereby being capable of meeting general loading conditions for carrying out the double roof greening on a building roof; meanwhile, the substrate contains sufficient organic nutrients and can supply fertilizer and hold moisture for a long time to meet nutritional requirements for the normal growth and propagation of plants; and the substrate has no peculiar smell and can effectively prevent damage caused by diseases and insects. Different paving thicknesses are adopted depending on different plant materials adopted for the double roof greening. The special substrate for the double roof greening can be widely applied to the greening of various double roofs.

Description

technical field [0001] The invention relates to a substrate, in particular to a composite roof greening substrate, its preparation method and application. Background technique [0002] There are two main ways of roof greening, one is duplex and the other is simple. Simple roof greening is currently used in most roof greening because of its lower requirements for building loads and lower construction and post-maintenance costs. However, complex roof greening is limited by building load requirements and construction and post-maintenance costs, so it cannot be widely applied. Generally, only high-end hotels, hotels, and villas adopt this greening method. [0003] One of the reasons for the high load requirements and high construction and post-maintenance costs is the planting substrate. At present, the common problem is that the substrate is heavy, the cost is high, and the substrate has many components, the source is complicated, and it is easy to breed diseases and insect p...
