Problems solved by technology

But these technologies all have certain limitations, as the Chinese patent (application) No. 200810035554.X used moss provenance comes from arid desert areas, because the growth and development of moss crust has very large spatial differentiation, its research results cannot It is directly popularized and applied in the loess plateau area where the water condition is relatively good, and the soil, climate, and vegetation coverage conditions are completely different from the desert area; the Chinese patent (application) No. 201410586406.2 is carried out in an artificial climate room, and the environmental conditions set are higher than those in the wild. Superior, successfully cultivated moss crusts may have weak stress resistance, and their adaptability to the outside world needs to be explored; at the same time, the planting method used is the sowing method, and the efficiency is relatively slow
At the same time, these technologies are only small-scale research, and the moss crust has not been truly applied to the treatment of environmental protection. Therefore, it is urgent to find a new method of treatment with high efficiency and suitable for field slopes in practice.

Embodiment 1

[0036] 1 Materials and methods

[0037] 1.1 Collection and preparation of samples required for inoculation

[0038] The mossy crust samples were collected from the natural slope of Zhifanggou in Ansai County, Shaanxi Province (36°46′99″-36°52′44″N, 109°17′2″-109°18′50″E), The main vegetation in the sampling site is Populus simonii Moench., Caragana korshinskii Kom., and Stipa bungeana Trin., and the moss crust coverage is over 80%, with an average thickness of 11.45±0.51mm ( n=9).

[0039] Use a small shovel to scoop out the moss crust layer with a thickness of 1cm, put it into a clean plastic bag, take it back to the laboratory to dry naturally, manually pick out the plant residues, soil blocks, stones, etc. (FLB-100) crushed for later use. It was identified that the dominant species of moss crust tested was Didymodon vinealis (Brid.) Zand.

[0040] 1.2 Planting method

[0041] Two experimental factors were considered in this experiment: nutrient solution and shading rat...

Embodiment 2

[0074] Budget estimates for different measures, it can be seen that the construction cost of moss crust is cheaper than other measures;

[0075] Biological crust method is referring to the method of embodiment 1,

[0076] Herbal measures are illustrated with Bermudagrass as a typical example. The specific planting method is as follows: in late spring and early summer, prepare the slope for planting, and remove stones and construction waste on the slope; scoop up the bermudagrass lawn in pieces, wash the root soil, and divide the bermudagrass into several units. Seedlings; first soak the seedlings in clear water, and then plant in holes according to the row spacing of 8cm×8cm, plant 4 seedlings in each hole, and plant them at a depth of about 3cm. The planting holes are filled with doped base fertilizer, and finally covered with soil. Water thoroughly after planting to keep the slope moist (see Table 2).

[0077] Shrub measures are illustrated using Amorpha fragrans as an exa...

Abstract

The invention provides a moss-turf ecological restoration technique of project wound surfaces. The technique comprises the following steps: selecting moss turfs that grow naturally and well; obtaining moss stem and leaf fragments ( to be selected through a 80 mesh sieve); adding the moss fragments and other accessory materials at a certain ratio to a tank, and mixing the materials even to form slurry liquid; then spraying and inoculating the slurry liquid on a slope; taking targeted maintenance measures, and finally realizing ecological restoring of the project wound surfaces. After the paste slurry liquid is sprayed and inoculated on outdoor project wound surfaces, certain targeted maintenance measures are taken at the same time, thereby realizing fast restoring of the moss turfs. The technique has the advantages of low cost, fast effects and wide applications, develops a new way of corrosion prevention and ecological restoration, and owns a broad prospect of industrialization.

Description

technical field [0001] The invention belongs to the field of ecology, and in particular relates to an engineering wound ecological restoration technology of moss crusts. Background technique [0002] Engineering wound surface refers to the wound surface that destroys the original natural environment on the surface of the earth accompanied by various engineering measures implemented by human beings in production and life. Its shape may be flat or sloped. The damage to the surrounding environment is quite serious. It will not only change the original topography and surface cover, reduce soil stability and soil fertility, but also change the water level of groundwater, the heat environment and humidity environment of the surface, and cause local microclimates. changes, increasing the risk of soil erosion. General measures to prevent and control soil erosion mainly include plant measures and engineering measures. In comparison, engineering measures, such as mortar block stone ...
