Problems solved by technology

However, the applicability of this method is still limited. In many areas, especially in areas with freeze-thaw erosion, the freezing and pulling effect caused by freeze-thaw erosion and the erosion effect of hydraulic erosion make it difficult to hold the geocell on the slope. One year, the geocell is gradually lifted from the soil by freezing and pulling, or because the filled soil is washed and suspended, the fixation effect on the soil is lost in the later stage, and it is suspended on the soil surface. In many places, the slope geocell This problem exists in indoor soil-fixing greening, which leads to poor landscape effect in the later stage, which seriously limits its application range
Generally speaking, the protection and utilization technology of turf, especially alpine-related turf, is still relatively immature. There are many difficulties in the process of stacking turf that have not been resolved. A new turf replanting utilization method and application to solve the problems of the prior art

Embodiment 1

[0072] General situation of the implementation site: The elevation of a highway project is between 4000 and 5000m, and there are mainly two types of landforms along the line: mountainous landforms and plain landforms. Along the highway, there are alpine willow shrub meadows, snow-layered Rhododendron shrub meadows, Caragana shrub meadows, and alpine meadows. The climate along the road is cold, and it is difficult for plants to reproduce and grow. The environment is fragile, and once the ecology is damaged, it is difficult to recover. During the road construction, it is divided into two tender sections, one of which is located in the mountainous section, mainly including various shrub meadow types, and the meadow turf coverage is 90%; the second tender section is mainly located in the plain section, and there is still 5km in length The road section is adjacent to the reservoir, and the roadside vegetation is dominated by alpine meadows. The coverage of meadow turf that needs to...

Abstract

The invention relates to the technical field of ecological restoration, and particularly discloses a turf replanting utilization method and application. According to the method, when turf blocks are stacked and stored after being stripped, the stacking vitality change of the turf blocks is predicted according to the stripping stacking season of the turf blocks, geocells with side holes are adopted as framework supporting materials to slow down vitality attenuation, the turf blocks and the earthwork standard rooms are laid back on slopes along the contour lines at intervals during replanting, the geocells are filled with soil, and plants are sown. According to the method, the stacking duration of the turf blocks can be determined, the activity of the turf in the stacking process can be kept, the laying survival rate can be increased, the geocells can be recycled, the problem that the geocells in high and cold freezing and thawing areas are damaged by freezing and pulling is solved, the interference of livestock grazing on greening sites can be relieved, and the comprehensive effect of turf protection and slope vegetation recovery can be improved.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a turf replanting utilization method and its application. Background technique [0002] The ecological environment in the plateau area is fragile, it is difficult to protect the native meadow turf during the construction process, and the vegetation recovery period is long. Therefore, it is necessary to find more effective vegetation restoration methods to solve this problem. At present, the relevant technology is still immature, the cost is high, and there are many links in the construction. Each link alone or in combination may affect the survival rate of the turf. There is no unified construction process standard, so that the vegetation can be restored. The effect is difficult to guarantee. [0003] There is still a lack of research on the reasonable length of turf stacking. Some documents indicate that the turf stacking time should not exceed one year, but so ...
