Embodiment 1

[0046] Embodiment 1, the mixed cultivation substrate that is applicable to turfgrass is cultivated green grass

[0047] (1) Preparation of mixed cultivation substrate suitable for turfgrass

[0048] Sludge composting is composted according to the following process:

[0049] The sludge dehydrated by the sewage treatment plant with a mass ratio of 2:1 (mass moisture content is 82.87%, particle size is 1.70-4.00mm) and green waste (referring to wastes such as fallen leaves and branches in landscaping, The mass water content is 22.10%, and the particle diameter is 2~3cm) to mix to obtain the compost body; the mixture is composted in a drum-type composting reactor, and aerobic fermentation is carried out in a continuous ventilation mode, and in the composting process, the Air is blown into the lower side of the drum, and then the air is discharged from the upper side of the drum. The temperature of the pile body is kept at 55-65°C, and the composting is carried out for 3-5 days to...

Abstract

The invention discloses a mixed cultivation medium applicable to turfgrass and application of the mixed cultivation medium. The mixed cultivation medium applicable to the turfgrass is prepared from sludge composting, soil and coal gangue in mass ratio of (2-4):(10-12):(4-7). The application of the mixed cultivation medium to the turfgrass comprises the following steps: paving on a ground; sowing the seeds of the turfgrass into the mixed cultivation medium applicable to the turfgrass; and cultivating to obtain the turfgrass. The mixed cultivation medium applicable to the turfgrass has the advantages that the turfgrass is a plant through the mixed cultivation medium, instead of soil, so that the land resource can be saved, and the pressure from the demand of urban greening on soil can be relieved; the sludge composting provides the nutrient required by the turfgrass, so that the fertilizer can be saved, the sludge can be effectively utilized, and meanwhile, toxic components can be prevented from entering the food chain; the raw materials are rich in source, so that the cost is low; the preparation method is simple; the turfgrass growing time is reduced; in addition, the turfglass cultivation effect is good; pretreatment is saved before seed sowing; the mixed cultivation medium can be widely popularized.

Description

technical field [0001] The invention relates to a mixed cultivation substrate suitable for turfgrass and its application, belonging to the field of environmental engineering. Background technique [0002] In recent years, the construction of urban ecological civilization has attracted much attention, and greening has become an important indicator to measure the quality of urban environment. Lawn construction occupies an extremely important position in urban greening. Traditional lawn cultivation not only occupies a large amount of cultivated land, but also in the process of turf production, more than 2cm of loam is shoveled away, and the fertile loam is destroyed. At the same time, due to the limited fertility of loam soil, a large amount of chemical fertilizers need to be applied to ensure the nutrients needed for the growth of turfgrass, which brings serious environmental pollution problems. In addition, the lawn cultivation period is long, the turf is heavy, and transpor...
