Embodiment Construction

[0036] In order to make the objects and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] The urban sludge composting mixed matrix used in the present invention adopts air-dried and screened sludge compost produced by Zhengzhou Bagang Sludge Disposal Plant in Henan Province, together with agricultural waste rice bran, non-polar cultivation substrate vermiculite, perlite, etc. The sludge composting mixed substrate obtained by uniformly mixing according to a certain ratio. The physical and chemical indicators of the used sludge compost and its accompanying materials are shown in Table 1:

Abstract

The invention discloses a lawn produced by using urban sludge composting mixed matrix and a preparation method thereof, comprising the following steps: selecting air-dried and decomposed coarse compost of urban sludge for screening, and the particle size of the compost after screening is 2 mm to 5 mm Between; mix compost with any two of rice bran, vermiculite, and perlite, and stir evenly to obtain a mixed matrix; level the land; spray pesticides; lay an isolation layer; cover the mixed matrix evenly on the isolation layer ; Sow grass seeds evenly. After sowing, cover the mixed substrate with 0.5cm; cover with sunshade net. The invention can not only improve lawn quality, reduce production and planting costs, save land and water resources, but also consolidate water control achievements, promote energy saving and emission reduction, effectively eliminate a large amount of excess sludge produced during sewage treatment, and alleviate the gradual deterioration of garden substrates. The pressure of scarcity and unstable source is a very valuable and sustainable method of sludge resource utilization.

Description

technical field [0001] The invention relates to a soilless lawn and a preparation method thereof, which is a lawn produced by using urban sludge composting mixed matrix and a preparation method thereof. Background technique [0002] Lawns play an irreplaceable role in beautifying the environment, maintaining water and soil, and purifying the air. With the rapid development of urbanization, people's demand for lawns and grade requirements are increasing day by day. The rapid establishment of high-quality turf has become one of the important topics in current turf research. The production of high-quality turf is not only related to grass species, but also closely related to the choice of turf cultivation substrate. Traditional lawn production substrates are generally taken from farmland, which seriously damages the soil structure, and it is difficult to control diseases, insect pests and weeds, and the production cycle is long. Some cities use construction waste as planting...
