Embodiment 1

[0033] Mix 60 parts of construction waste with a particle size of 0.5-4mm, 20 parts of peat, and 10 parts of urban domestic sludge organic fertilizer, mix and stir evenly, and spread the thickness of 10-15cm, directly plant the buddha grass, water once every two weeks, 1 It will become a ping in a month. The buddha grass grows luxuriantly and no dead seedlings and wilt occur in the later growth.

Embodiment 2

[0035] Mix 80 parts of construction waste with a particle size of 0.5-5mm, 10 parts of peat, and 10 parts of urban domestic sludge organic fertilizer, mix and stir evenly, spread 30cm thickness, and directly plant jasmine flowers, water once every two weeks, and bloom after 3 months , And no dead seedlings or wilt occurred in the later growth.

Embodiment 3

[0037] Mix 90 parts of construction waste with a particle size of 0.5-4mm, 20 parts of peat, and 20 parts of urban domestic sludge organic fertilizer, mix and stir evenly, lay a thickness of 20cm, and directly plant coarse rib grass, watering once every two weeks, 1 month It grows 3-5cm later, and there is no dead seedling or withering in the later growth.

[0038] The organic garden soil of the present invention solves the problem of soil compaction degradation caused by only using inorganic fertilizers, and is rich in a large amount of organic matter and trace elements that are helpful for plant growth, and improves the activity and nutrients of the organic garden soil; at the same time, the organic garden The soil has good water retention and ventilation properties, which can ensure the normal growth of green plants. It can be seen from Examples 1-3 that the plants prepared by using the organic garden soil of the present invention are growing well, and there is no dead seedlin...

Abstract

The invention relates to the technical field of garden soil, in particular to organic garden soil prepared from building waste and municipal sludge, which is prepared from building waste, municipal sludge organic fertilizer and peat soil according to the ratio of (60-90):(10-20):(10-20) by good mixing and stirring; the municipal sludge organic fertilizer is prepared from, by weight, 100 parts of dried sludge, 2-10 parts of quicklime, 15-30 parts of saw dust, 2-10 parts of phosphoric acid and 1-5 parts of a fermenting microbial agent. According to the invention, the building waste and the municipal sludge are selected as main materials, so that the problem of sludge pollution is solved, the resource utilization of the solid waste is achieved; and meanwhile, the prepared organic garden soilhas good water retention, fertilizer retention and ventilation performances, and the normal growth of greening plants is guaranteed.

Description

Technical field [0001] The invention relates to the technical field of garden soil, in particular to an organic garden soil prepared from construction waste and urban sludge. Background technique [0002] With the continuous development of urban construction across the country, the construction of old city reconstruction, new village construction, factory expansion, commercial housing construction and decoration has accelerated, and a large amount of construction waste is generated every year. Construction waste is mainly composed of muck, crushed stone, broken brick, It is composed of waste mortar blocks, waste concrete blocks, waste glass, waste ceramics, waste asphalt blocks, waste plastics, waste metal materials, waste bamboo and wood. At present, most of the construction waste in our country is mostly piled in the open or landfilled, and a very small part is used as the raw material of recycled aggregate or recycled cement and other construction products required for constru...
