Lawn produced from municipal sludge compost mixed matrixes and preparation method thereof

Abstract

The invention discloses a lawn produced from municipal sludge compost mixed matrixes and a preparation method of the lawn. The preparation method comprises the following steps that air-dried decomposed coarse municipal sludge compost is selected for screening, and the grain diameter of the screened compost ranges from 2 mm to 5 mm; the compost is mixed with any two of rice chaff, vermiculite and perlite, and the mixture is stirred evenly to obtain the mixed matrixes; the land is leveled; insecticide is sprayed; an isolation layer is laid; the isolation layer is evenly covered with the mixed matrixes; grass seeds are evenly sown and are covered with the mixed matrixes for 0.5 cm after seeding is completed; the mixed matrixes are covered with a sunshade net. By means of the preparation method, the quality of the lawn can be improved, production cost and planting cost can be lowered, and land and water resources can be saved; moreover, the water control effect can be consolidated, energy conservation and emission reduction can be promoted, a large amount of excess sludge generated in the sewage disposal process can be effectively eliminated, pressure from gradual deficiency of garden matrixes and unstable sources can be relieved, and therefore the preparation method is a sustainable sludge recycling method with extremely high application value.

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...
