Abstract

The invention discloses a method for regulating greenness of a compost medium festuca arundinacea by means of hydroxylated multi-walled carbon nanotubes. The method comprises the steps that a compounded medium is loaded into plastic pots separately, and 5 g of festuca arundinacea is seeded into each pot, wherein the indoor temperature ranges from 18 DEG C to 25 DEG C, the relative humidity ranges from 35% to 65%, light illumination adopts natural light which permeates indoors, and the illumination intensity ranges from 6,856 LX to 27,090 LX; the positions of the pots are changed frequently to ensure illumination consistency, quantitative water feeding is conducted every day during the planting period, and therefore water needed by growth of plants is guaranteed; culture is conducted for 130 d, the first crop is mowed on the 65 d, and the plant height and biomass are measured; mowing is conducted on the 130 d, and related indexes are determined. It is shown through experimental results that the early-stage growth greenness of overground parts of the compost medium festuca arundinacea can be improved by means of the carbon nanomaterials.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and relates to a method for improving the greenness of tall fescue as a compost matrix by using carbon nanometer materials. Background technique [0002] Household garbage mainly refers to the solid waste generated in residents' daily life and production. Global domestic waste will increase by 51% from 2005 to 2025. The average annual growth rate of domestic waste in my country exceeds 15%, and the accumulation of waste piles across the country has occupied more than 500 million square meters of land. By 2015, the annual domestic waste production in some of our cities is expected to exceed 10 million tons. The distribution of physical components of domestic waste is mainly inorganic matter such as glass, brick tiles, and cinder ash, and organic matter such as plants, fibers, plastics, and paper, among which compostable matter accounts for more than 30%. The chemical components ...
