Abstract

The invention provides a method for recovering vegetation in a rock-soil residue field, comprising the following steps: 1) removing unstable rocks and sundries on the residue stack and maintaining a certain degree of smoothness; 2) anchoring thread steel arranged in quincunx into the residue stack and pouring anchoring agents for fixation; 3) preparing a compound of vegetable fibers and bentonite; 4) paving the compound obtained in the step 3) on the surface of the residue stack and compacting the compound; 5) spreading and hanging galvanized wire meshes along the grade surface and binding the meshes with tie wires and fixing the meshes on the thread steel; 6) preparing seed matrix mixtures; 7) spraying the seed matrix mixtures; and 8) spreading and hanging non-woven fabrics and watering and managing the fabrics. The method features reasonable cost, simple construction technology, stable structure of the vegetation in the rock-soil residue field during recovery and good water retention, and can effectively recover the vegetation. The method is mainly used for recovering the vegetation in the rock-soil residue field.

Description

technical field

[0001] The invention relates to a method for restoring vegetation in the fields of soil and water conservation and ecological environment construction, in particular to a method for restoring vegetation in rock and soil slag fields. Background technique

[0002] Rock-soil slag field is a kind of wound accumulation inevitably produced in the construction of highways, railways, hydropower, mines and other basic projects. It is often in a critical state of instability due to disorderly accumulation of slag and loose structure. A large area of ​​water and soil erosion will be formed in the soil residue field, which seriously damages the ecology and even endangers public property and people's lives.

[0003] Chinese patent CN 100350106C discloses a soil and water conservation and ecological restoration method for spoil field, which is characterized in that it adopts ecological restoration measures combining biological measures and engineering measures, uses vetive...
