Embodiment 1
[0049] (1) The domestication process of domestic waste composting substrate Tall fescue: The domestic waste composting substrate was flatly spread on the experimental ground, and then the compost was compacted and flattened by pressing. The average thickness of the composting substrate was 20cm. The sowing method is spring sowing, and the domestication of tall fescue in fertilizer substrate depends on natural precipitation in each year, and the seeds of tall fescue are harvested after 4 years of domestication;
[0050] (2) The domesticated tall fescue seeds were treated with 130g / m 2 Seeding; culture temperature is 25°C, relative humidity is 40%, mow after 20 days of emergence, stubble height is 2cm; start watering after 5 days containing Cd 2+ 、Cr 6+ 、Cu 2+ , Pb 2+ The four heavy metal solutions were poured three times, and the heavy metal solution was poured every 5 days; the stress concentrations of the four heavy metal ion solutions in the soil reached 30, 600, 600, an...

[0055] (1) The domestication process of domestic waste composting substrate Tall fescue: The domestic waste composting substrate was flatly spread on the experimental ground, and then the compost was compacted and flattened by pressing. The average thickness of the composting substrate was 20cm. The sowing method is spring sowing, and the domestication of tall fescue in fertilizer substrate depends on natural precipitation in each year, and the seeds of tall fescue are harvested after 4 years of domestication;
[0056] (2) The domesticated tall fescue seeds were treated with 130g / m 2 Seeding; culture temperature is 23°C, relative humidity is 40%, mow after 20 days of emergence, stubble height is 2cm; start watering after 5 days containing Cd 2+ 、Cr 6+ 、Cu 2+ , Pb 2+ The four heavy metal solutions were poured three times, and the heavy metal solution was poured every 5 days; the stress concentrations of the four heavy metal ion solutions in the soil reached 30, 600, 600, an...
