Embodiment 1
[0054] A method for regulating the growth of tall fescue in compost matrix lawn by modified nano-carbon:
[0055] (1) Handling of materials:
[0056] Before the experiment, the garbage compost was pretreated to remove the plastic film, bricks, stones and large glass debris. After air-drying, it passed through a 2mm sieve for later use; the physical and chemical properties of the garbage compost were: pH 7.62, organic matter content 221.25g kg -1 , total nitrogen 13.48g·kg -1 , available phosphorus 0.078g·kg -1 , C / N is 8.37, saturated water content is 0.76mL·g -1 , bulk density 0.85g·mL -1 ; Heavy metal (Cr, Cu, Pb, Zn) contents were 67.00, 238.73, 172.11 and 496.38mg·kg -1 ;
[0057] The plants are tall fescue (Festucaarundinacea L.);
[0058] The nano-carbon particle size is 20nm, and the specific surface area is 1.2×10 5 m 2 kg -1 , with a pH value of 7, which were modified before application to obtain KMnO 4 、H 2 SO 4 or HNO 3 Modified nano carbon;

Embodiment 2
[0062] A method for regulating the growth of tall fescue in compost matrix lawn by modified nano-carbon:
[0063] (1) Handling of materials:
[0064] Before the experiment, the garbage compost was pretreated to remove the plastic film, bricks, stones and large glass debris. After air-drying, it passed through a 2mm sieve for later use; the physical and chemical properties of the garbage compost were: pH 7.62, organic matter content 221.25g kg -1 , total nitrogen 13.48g·kg -1 , available phosphorus 0.078g·kg -1 , C / N is 8.37, saturated water content is 0.76mL·g -1 , bulk density 0.85g·mL -1 ; Heavy metal (Cr, Cu, Pb, Zn) contents were 67.00, 238.73, 172.11 and 496.38mg·kg -1 ;
[0065] The plants are tall fescue (Festucaarundinacea L.);
[0066] The nano-carbon particle size is 50nm, and the specific surface area is 1.2×10 5 m 2 kg -1 , with a pH value of 7, which were modified before application to obtain KMnO 4 、H 2 SO 4 or HNO 3 Modified nano carbon;

Embodiment 3
[0070] A method for regulating the growth of tall fescue in compost matrix lawn by modified nano-carbon:
[0071] (1) Handling of materials:
[0072] Before the experiment, the garbage compost was pretreated to remove the plastic film, bricks, stones and large glass debris. After air-drying, it passed through a 2mm sieve for later use; the physical and chemical properties of the garbage compost were: pH 7.62, organic matter content 221.25g kg -1 , total nitrogen 13.48g·kg -1 , available phosphorus 0.078g·kg -1 , C / N is 8.37, saturated water content is 0.76mL·g -1 , bulk density 0.85g·mL -1 ; Heavy metal (Cr, Cu, Pb, Zn) contents were 67.00, 238.73, 172.11 and 496.38mg·kg -1 ;
[0073] The plants are tall fescue (Festucaarundinacea L.);
[0074] The particle size of nano carbon is 70nm, and the specific surface area is 1.2×10 5 m 2 kg -1 , with a pH value of 7, which were modified before application to obtain KMnO 4 、H 2 SO 4 or HNO 3 Modified nano carbon;
