Problems solved by technology

[0006] The first purpose of the present invention is to solve the problem of rapid recovery of vegetation in sandy wastelands due to factors such as unreasonable human production activities, drought, poor soil, and insufficient source of soil seed banks for a long time, and to provide a mine relic in arid desert areas. Artificial seed bank for vegetation ecological restoration, using artificial seed bank for vegetation restoration from an engineering point of view, so as to realize vegetation ecological restoration of mine sites in arid desert areas

Embodiment 1

[0019] Take the geological environment management and ecological restoration of iron placer mine in Qinghe County-the geological environment management of the head area of ​​Awei irrigation canal as an example. The project area is an arid desert ecosystem, and the surrounding ecological community is the desert grassland sericaria group, with a restoration area of ​​36 hectares.

[0020] Regional pioneer vegetation and dominant vegetation seed selection:

[0021] In the head area of ​​the Awei Irrigation Canal, the building complex consists of desert plants such as super-xerophytic, xerophytic small shrubs, small semi-shrubs, early-growing annual herbs, perennial herbs, and middle-growing ephemeral plants. The regional vanguard vegetation is selected as quinoa and Suaeda salsa, and 3.65 kg of net species of quinoa and 18 kg of suaeda are weighed respectively; the dominant vegetation is selected as prickly pear, wheatgrass, silkworm, needlegrass, and nasturtium, which are weighe...

Embodiment 2

[0039] Take the geological environment management and ecological restoration of the iron placer mine in Qinghe County - the geological environment management of the eastern area of ​​the north bank of the Wulun Ancient River as an example. The project area is an arid desert ecosystem, and the surrounding ecological community is the Haloxylon system of small desert trees, with a restoration area of ​​194 hectares.

[0040] Regional pioneer vegetation and dominant vegetation seed selection:

[0041] In the eastern part of the north bank of the Ulungu River, the building plants consist of super-xerophytic, xerophytic small shrubs, small semi-shrubs, early-growing annual herbs, perennial herbs and middle-growing ephemeral plants and other desert plants. The pioneer vegetation in the area is Kochia scoparia and Nassau chinensis. Weigh 37 kilograms of Kochia scoparia and 138 kilograms of Nassau sativa respectively. Weigh 420 kg of net seeds Haloxylon, 70 kg of Seraphim, 228 kg of C...

Abstract

The invention discloses an arid desert area mine slash vegetation ecological restoration artificial seed bank. The artificial seed bank comprises the following components in parts by mass: 1-3 parts of regional pioneer vegetation seeds, 15-30 parts of regional dominant vegetation seeds, 50-125 parts of a drought-resistant restoration matrix and 0.70-0.80 part of a bird, mouse, rabbit and poultry repellent. The invention also provides a preparation method thereof. The artificial seed bank achieves the purpose of large-area soil seed bank supplementation during ecological restoration of the mineslash in the arid desert area, the germination rate is increased, growth in the seedling stage is promoted, the stress resistance is improved, natural germination forms vegetation communities, multiple species coexist, the structure is stable, and self-renewal and restoration of the ecological restoration area are achieved; the desert vegetation artificial seed bank is easily available in materials, low in cost, simple and feasible, and suitable for popularization and application in the technical field of vegetation ecological restoration of mine slash in arid desert regions.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration of mine traces in arid desert areas, and in particular relates to an artificial seed bank for ecological restoration of mine traces in arid desert areas and a preparation method thereof. Background technique [0002] Desertification is the degradation of land in arid, semi-arid and dry sub-humid areas. Human activities and climate change are the direct causes of desertification. my country is one of the countries that are seriously harmed by desertification. In recent years, important achievements have been made through research and governance, but the overall situation is still grim. The area of ​​China's arid, semi-arid and sub-humid arid regions accounts for 38.3% of the country's land area. In the arid and semi-arid areas of the north, due to the long-term unreasonable long-term exploitation of mineral resources by human beings, overloaded grazing of grasslands, overexploitatio...
