Problems solved by technology

[0003] However, in the roof greening project in the prior art, the thickness of the planting soil needs to be at least 40cm-60cm, and the load requirements on the roof structure are relatively high, and the engineering volume is large and the maintenance cost is high; for the roof of the old building, the old The roof load of old buildings is small, and the waterproof, windproof, and water retention capabilities are poor, which makes it difficult for the roof greening projects in the prior art to be applied to the roofs of old buildings; and the proportion of old buildings in cities is much higher than that already implemented Therefore, it is imminent to develop a greening technology suitable for the roof of old buildings

Abstract

The invention relates to a planting medium formula suitable for greening old building roofs and a preparation method thereof, and the planting medium formula is a blocky planting medium prepared by solidifying ceramsite and planting soil according to a certain proportion, so that modular and industrial production is facilitated; the planting soil is light planting soil prepared by fermenting kitchen garbage through combination of humus soil, various organic wastes and beneficial bacteria, so that the planting soil is rich in N, P, K and various trace elements, rich in nutrition and relatively light in mass, meanwhile, the permeability of the soil is enhanced, the structure of the soil is improved, and the planting soil has the effects of preserving moisture and fertility; the method is suitable for greening engineering of old building roofs.

Description

technical field [0001] The invention relates to the technical field of old building roof greening, in particular to a planting base formula suitable for old building roof greening and a preparation method thereof. Background technique [0002] China is in the rapid development stage of urbanization. Promoting roof greening in limited urban space can not only expand the green area, but also effectively improve the utilization rate of land resources, alleviate atmospheric dust and urban heat island effect, purify the air, increase the Humidity, reducing urban noise, and roof greening can also reduce the temperature inside the building by 3 to 5 degrees, which has a significant effect on heat insulation and energy saving. [0003] However, in the roof greening project in the prior art, the thickness of the planting soil needs to be at least 40cm-60cm, and the load requirements on the roof structure are relatively high, and the engineering volume is large and the maintenance cos...
