Abstract

The invention discloses a method for regulating actinomycete diversity of a lawn compost medium by means of carbon nanomaterials. The method starts from the perspective of medium microorganisms, a mixture of domestic rubbish compost and soil serves as a lawn medium material, four different carbon nanomaterials are mixed with the lawn medium material separately, and obtained mixtures serve as treatment groups; by means of lawn plant cultivation and addition of different carbon nanomaterials, changes of the diversities of actinomycetes cultured in the medium are known. It is shown through experimental results that after the carbon nanomaterials are added into the rubbish compost lawn medium, the actinomycete diversities of the treatment groups treated with other carbon nanomaterials except carbon nanotubes are all increased in various degrees, and the diversity index of graphene oxide treatment is the highest and has a significant difference with the control group. According to the method for regulating the actinomycete diversity of the lawn compost medium by means of the carbon nanomaterials, the carbon nanomaterials are added into a lawn establishment system, and technological support is provided for achieving regulation application to the actinomycetes.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a method for regulating the diversity of lawn composting matrix actinomycetes by using carbon nanometer materials. Background technique [0002] Carbon nanomaterials are materials in which at least one of the three-dimensional structures is smaller than 100 nm. Carbon nanomaterials have the characteristics of small size, large specific surface area, high surface energy, and large proportion of surface atoms, and have shown excellent performance in mechanics, optics, heat, and electricity. Nanoparticles have many micro-interfaces, through which various interfacial reactions can be strengthened, and play a significant role in soil heavy metal pollution and sewage purification. [0003] Carbon content is very high in nature, and it is also very important for organic matter and life. In 1985, scientists discovered that C is composed of 60 C atoms. 60 . Subsequently...
