Embodiment 1
[0037] Tall fescue (F. arundinacea Schreb.), variety Houndog 5, was used as grass seeds to prepare turf. The grass seeds were provided by DLF International Seeds, and the germination rate was ≥85%.
[0038] The test site is located in the Beijing Forestry University Lawn Experimental Station of Dongbeiwang Horticultural Field, Haidian District, Beijing.
[0039] The municipal waste compost used in this example was provided by Beijing Huairou Comprehensive Waste Treatment Plant; the sand was commercially available medium sand.
[0040] The basic physical and chemical properties of the used municipal waste compost, sand and field soil in this embodiment are shown in Table 1.
[0041] Table 1 Basic physical and chemical properties of the test matrix
[0042]
[0043] In this example, different volumes of urban waste compost and commercially available sand were mixed (see Table 2) as the turf cultivation substrate, and field soil was used as a comparison. The specific substrat...
Embodiment 2
[0075] The grass species used in this embodiment is tall fescue, and the variety is Houndog 5 (Houndog5).
[0076] In this embodiment, tall fescue is cultivated using the soilless turf cultivation substrate prepared by municipal waste composting, and the cultivation steps are as follows:
[0077] (1), preparation matrix
[0078] If the matrix is too thick, the production cost and transportation cost (weight) of the turf will be increased, and the content of heavy metals in the matrix will be more. If the substrate is too thin, the water and fertilizer retention capacity of the substrate will be poor, and the management cost will increase. At the same time, if the substrate is light, the turfgrass seeds will be easily washed away, and the lawn bed will be easily washed away. The specific thickness should be determined according to the situation.
[0079] Mix 60% urban garbage compost and 40% sand by weight, spread it flat on the lawn bed, and properly suppress or water it t...
Embodiment 3
[0094] In this embodiment, the perennial ryegrass is cultivated using the soilless turf cultivation substrate prepared by municipal waste composting, and the cultivation steps are as follows:
[0095] (1) Preparation of matrix
[0096] Mix 60% urban garbage compost and 40% sand by weight, spread it flat on the lawn bed, and properly suppress or water it to allow natural settlement to prepare a cultivation substrate with a thickness of 2.5-5cm.
[0097] If the matrix is too thick, the production cost and transportation cost (weight) of the turf will be increased, and the content of heavy metals in the matrix will be more. If the substrate is too thin, the water and fertilizer retention capacity of the substrate will be poor, and the management cost will increase. At the same time, if the substrate is light, the turfgrass seeds will be easily washed away, and the lawn bed will be easily washed away. The specific thickness should be determined according to the situation.
