Abstract

The invention discloses a regulation and control method for improving diversity of nanocarbon to soil nematodes. The method comprises the steps of adopting plastic flowerpots of which the lengths are 25cm and the diameters are 2cm, cleaning and drying gauzes, fixing each gauze which is cut to a round shape with a proper size at the bottom of each flowerpot, and weighing matrix garden soil of 2kg in each container, wherein modified nanocarbon of which the weight is 1-5% that of the matrix garden soil is added into the garden soil respectively; respectively sowing festuca arundinacea seeds of 4.5g respectively; regularly quantitatively watering in the experiment period every day to meet the plant growth demands, culturing the plants in a laboratory, wherein during the cultivation period, the temperature is 25-34 DEG C, the relative humidity is 31-48%, the lighting condition is natural incident light, the experiment time is 120 days, the nematodes in the soil are separated to identify the type and number of the nematodes as the background data of the nematodes, and the type and number of the nematodes are processed after separation and identification after 4 months.

Description

technical field

[0001] The invention belongs to the technical field of environmental protection, and relates to urban greening, in particular to a method for regulating the diversity of lawn soil matrix nematodes by modified nano-carbon. Background technique

[0002] Carbon black is the product of the gaseous process, which is converted from the volatile components of biomass or fossil raw materials during incomplete combustion or high-temperature pyrolysis. Usually, carbon black is a porous nanomaterial with a diameter of 30-50 nm, with a large specific surface area and high active sites.

[0003] In the 1980s, the annual global carbon black production was approximately 50-270 Tg (Tg=10 12 g) or so, of which about 80% is due to combustion. Most of the carbon black directly enters the soil, accumulates gradually, and becomes an important component of soil organic matter, and the other part is lifted into the atmosphere by the wind. Due to the inert nature of carbon black,...
