Abstract

The invention discloses a method adopting salt-tolerant reinforcement nanometer garbage compost for reinforcing turf grass salt resistance. Salt-tolerant microbes are extracted from compost, pure salt-tolerant microbes are obtained through screening, a method for gradually improving NaCl concentration is adopted for further reinforcing and refining a reinforcement salt-tolerant bacterium agent, and the salt-tolerant bacterium agent and nanometer garbage compost are jointly applied to a saline-alkali soil turf medium. Three kinds of mild, medium and server salt stress treatment are designed by the experiment, reinforcement microbes are combined with nanometer garbage compost to reinforce the salt resistance of turf grass so as to provide basis for development of an effective fertilizer, improvement of salt resistance of turf grass and saline-alkali soil property and promotion of turf establishment in a salt stress environment.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a method for enhancing the salt resistance of turfgrass by adopting salt-enhanced active nano-garbage composting. Background technique [0002] Nano-science and technology (Nano-ST) is a new technology that emerged in the late 1980s. It mainly studies the structural scale in (10 -7 -10 -9 m) The properties and applications of substances within the scope. Because nanomaterials have basic characteristics such as interface surface interface effect, small size effect, macroscopic quantum tunneling effect and quantum size effect, there are many strange properties that traditional materials do not have. Nanomaterials exhibit characteristics different from traditional materials in terms of absorption, catalysis, magnetic effects, and sensitive properties, and can be highly intersected with multiple fields, including physics, chemistry, electronics, materials science,...
