Method for ecological restoration of abrupt slope by using biological bacteria humus

Abstract

The invention discloses a method for ecological restoration of an abrupt slope by using biological bacteria humus, which comprises the following steps of: analyzing overground species, screening suitable local species by using an underground seed bank analysis method, treating a slope surface, applying biological bacteria humus at the bottom, performing mixed material wet spray-seeding, performingstraw mat cover maintaining and managing and the like. Wherein indigenous species suitable for planting in the restoration area can be accurately screened by combining restoration area surface vegetation survey and underground seed bank species comparison, on one hand, interference of foreign species can be minimized, and long-term continuous recovery capacity can be increased for natural ecological balance, so that the survival rate of plants can be effectively increased, and the survival rate of the plants is increased; mortality rate caused by the fact that plants do not adapt to local soil and climate is greatly reduced, large-area multiple reseeding is avoided, and the repairing efficiency and the long-term ecological repairing effect are greatly improved. On the other hand, the transition period of pioneer species can be omitted through vegetation species selection, native species suitable for being planted in the restoration area are screened out, the original ecological environment can be restored earlier, and the purpose of early effectiveness is achieved.

Description

technical field [0001] The invention belongs to the technical field of natural ecological restoration, and in particular relates to a method for ecological restoration of steep slopes by using biological fungus humus. Background technique [0002] Promoting the construction of ecological civilization and promoting sustainable economic and social development has become the consensus of the whole society. The "Overall Plan for the Reform of the Ecological Civilization System" requires the establishment of the concept of "lucid waters and lush mountains are golden mountains and silver mountains" and actively carry out pilot experiments. Encourage all regions to proceed from local realities, focus on solving outstanding ecological and environmental problems, take the initiative, and actively explore and promote the construction of ecological civilization. Due to the exposed slopes and no vegetation coverage on the surface of the slag site during the construction of the traffic m...

AI Technical Summary

Problems solved by technology

Due to the exposed slopes and no vegetation coverage on the surface of the slag site during the construction of the traffic municipal project, it usually leads to soil erosion and dust, which reduces the self-healing ability of the soil and destroys the underground soil seed bank. If there is no beneficial artificial intervention, the ecological restoration The process will be long and difficult

At present, when carrying out ecological restoration on steep slope wounds of barren hills, plants are usually planted on the surface of bare slopes and slag fields. However, the soil on the surface of bare slopes and slag fields is poor, so it is difficult for plant seeds to survive, and the survival rate is low, so they need to be replanted continuously. The repair time is very long, the repair effect is poor, the time cost and labor cost required for post-maintenance are extremely high, and it is difficult to plant due to the slope problem, the construction is difficult and the construction intensity is high
