Problems solved by technology

However, although there are reports of using construction waste in the current recycled garden soil, there are few application examples of using construction waste and plant ash at the same time.
Moreover, due to the unreasonable allocation of raw material components in the existing recycled garden soil, the synergistic effect between the components is not fully considered, but the functions of the components are simply superimposed, which often results in strong water retention and fertilizer retention, but poor water and air permeability. ; Water retention and fertilizer retention are poor after water permeability and air permeability are guaranteed. root rot

Embodiment 1

[0024] A garden soil compounded by recycled construction waste products and agricultural waste, consisting of the following components in mass percentage: 65% construction waste spoil, 10% regenerated sandstone, 10% regenerated ceramsite, and 15% plant ash.

[0025] Recycled sand is a recycled product made from construction waste. The mass percentage of sand and fine stone is 50% each, the particle size of fine stone is ≤15mm, and the fineness of sand is 0.5mm. Regenerated ceramsite is a recycled product made from construction waste, with a particle size of ≤15mm. Plant ash needs to adjust the Ph value to 5.5-7.5.

[0026] Fully mix and stir each component according to the stated mass percentage, and then compact the mixed regenerated compound garden soil in spring or other seasons suitable for plant growth to plant garden plants. The soil depth is 1.5m (compressed After fruiting), watering with appropriate amount of water is enough.

Embodiment 2

[0028] A garden soil compounded by recycled construction waste products and agricultural waste, consisting of the following components in mass percentages: 70% construction waste spoil, 10% regenerated sandstone, 10% regenerated ceramsite, and 10% plant ash.

The mass percentage of sand and fine stone is 50% each, the particle size of fine stone is ≤15mm, and the fineness of sand is 0.2mm. Regenerated ceramsite is fly ash ceramsite, particle size ≤ 15mm. Plant ash needs to adjust the Ph value to 5.5-7.5.

[0030] Fully mix and stir each component according to the stated mass percentage, and then compact the mixed regenerated compound garden soil in spring or other seasons suitable for plant growth to plant garden plants. The soil depth is 1.5m (compressed After fruiting), watering with appropriate amount of water is enough.

Embodiment 3

[0032] A garden soil compounded by recycled construction waste products and agricultural waste, composed of the following components in mass percentage: 75% construction waste spoil, 10% regenerated sandstone, 10% regenerated ceramsite, and 5% plant ash.

Abstract

The invention relates garden soil prepared from construction waste recycled products and agricultural wastes and a preparation method thereof. The garden soil is composed of 65-75% of construction waste spoils, 10% of reclaimed gravels, 10% of reclaimed haydite, and 5-15% of plant ash, wherein the reclaimed gravels and the reclaimed haydite are all recycled products prepared by processing construction wastes, and the plant ash is required to be subjected to acid regulating treatment. According to the invention, a large amount of construction waste recycled products and agricultural wastes are utilized, so that the land occupied problem can be solved, and an effect of changing waste material into things of value can be achieved; and the garden soil prepared according to the invention is good in water retention, fertilizer conservation, air permeability and water permeability, and plants cultivated by using the garden soil grow well and are boughy.

Description

technical field [0001] The invention relates to a garden soil prepared from recycled construction waste products and agricultural waste, in particular to a kind of economical, environmental protection, recycling and regeneration suitable for plant growth by adding agricultural waste to the recycled products processed from construction waste. garden soil. Background technique [0002] In the process of urbanization, as a product of urban metabolism—construction waste has increased the burden on urban development, and many cities around the world have been surrounded by waste. According to statistics, construction waste has accounted for 30%-40% of the total urban waste. Construction waste is mainly composed of muck, crushed stones, broken bricks, waste mortar blocks, waste concrete blocks, waste glass, waste ceramics, waste asphalt blocks, waste plastics, waste metal materials, waste bamboo and wood, etc. At present, the main ways to deal with construction waste in my count...
