[0006] ① Turf production mostly uses high-quality tillage soil as the substrate. A turf production requires about 5 cm thick tillage soil. In this way, fertile tillage soil resources will be brought into the urban ecosystem along with the sale of turf, while farmland After several times of turf production, it

Embodiment

[0035] Sieve the composted waste from Tianjin Xiaodian Waste Treatment Plant (1 cm x 1 cm sieve), put it in an oven, and dry it to constant weight at 80°C to prepare for lawn plants Culture substrate. The air-dried yellow slime excavated from the foundations of urban buildings is crushed, sieved and sorted (1 cm × 1 cm sieve), and prepared as a composite material for turf cultivation substrates. The lawn plant species is tall fescue which is widely used in Northeast, Northwest and North China.

[0036] The amount of compost waste substrate for lawn plant cultivation is 40g, and the cultivation container is a petri dish with a diameter of 10cm. Sow 200 tall fescue seeds evenly on the compost waste substrate.

[0037] Tall fescue is carried out on a greenhouse plant cultivation platform, the light is natural light entering the room, the intensity is 1700-2100 lux, the temperature is 14°C-25°C, and the relative humidity is 40%-70%. After the tall fescue is sown and the lawn pl...

Abstract

A matrix for culturing the lawn in urban area is prepared from the compost of city life garbage (48-93 Wt%) and yellow clay (7-52 Wt%).

Description

technical field [0001] The invention relates to an urban carpet turf substrate and a preparation method thereof, which is a resource utilization of urban domestic garbage and urban building excavation foundation yellow slime and a soilless cultivation technology for urban turf. technical background [0002] Over the years, the stockpiling volume of municipal solid waste in my country has exceeded 6 billion tons, and the resource utilization rate is less than 5%. The vast majority of waste is in an idle and chaotic stacking state. a special resource. [0003] The underground yellow slime excavated from the foundation of urban buildings is located deep below the urban soil layer. In fact, the parent minerals in the lower layer of the soil are relatively viscous. After being dug out, they are treated as general construction waste and have little utilization value. Big. Yellow slime is rich in resources and very economical, without cost. [0004] Lawn greening has become an im...
