Rapid composting method for ecological bank slope soil

Abstract

The invention provides a rapid composting method for ecological bank slope soil. The rapid composting method comprises the steps that (1), kitchen wastes without grease and salt are mixed with crop residual products, after high-temperature dehydration and sterilization, the mixture and waste mushroom fungus sticks which are sterilized at high temperature are mixed and smashed into particles; (2),in a container, the mixed particles and a few of biochar particles are laid layer by layer; (3), the container is subjected to semi-ventilation fermentation for one day at the temperature of 60-80 DEGC and cooled to room temperature; (4), after fermentation is completed, materials in the container are significantly stirred and mixed to obtain compost ecological soil; (5), the compost ecological soil obtained after fermentation is further smashed into a granular structure of 1-2 micrometers. The ecological bank slope soil processed by using the method can provide microorganisms and nutrients for a bank slope environment, the soil breathability can be enhanced, the bank slope structure is stabilized, a slope runoff purifies soil water, and contamination, caused by eutrophication, to water and soil is reduced.

Description

technical field [0001] The invention relates to the technical field of soil treatment, in particular to a rapid composting method for bank slope ecological soil. Background technique [0002] The soil on bank slopes of rivers and lakes is a place where bacteria, fungi and other microorganisms live together. These microorganisms play an important role in the manifestation of soil functions and are sensitive to changes in nutrients, water, heat and other environmental factors in the soil, especially at the junction of water and land in the river bank zone. , reflecting the changes in soil and water ecosystem functions, forming a balanced ecosystem with the riparian soil itself, providing a living environment for riparian vegetation and organisms. [0003] With the rapid development of urbanization, the drastic changes in urban land use have significantly affected the soil environment. Heavy metal pollution in urban soil mainly involves four heavy metal elements: zinc (Zn), le...

AI Technical Summary

Problems solved by technology

The traditional composting method takes a long time for microbial fermentation. If the composting materials are not thoroughly sterilized by high temperature, the eggs and bacteria carried by them will also pollute the composting body.
