The invention relates to a comprehensive ecological restoration method for a high-altitude desert salinized area based on a salt elimination and alkali reduction hydraulic structure cooperating with a mineral-based slow release agent. Comprising the following steps: preparing and applying a mineral-based slow-release agent, and mixing sulfur-containing minerals, an acidifying agent, crushed forestry and agricultural residues, clay minerals and an adhesive to prepare a slow-release matrix; the method comprises the following steps: constructing a hydraulic salt elimination activation system and implementing salt elimination, constructing a periodic efficient drainage geotechnical structure in a to-be-repaired area, coupling a drip irrigation system to form a hydrodynamic migration channel, and realizing leaching and discharging of soil salt and pre-activation of a slow release agent through spraying; microbial synergistic soil improvement is implemented, organic materials generated by compost fermentation of agricultural and pastoral wastes and an electroactive functional microbial agent are added, a slow-release matrix is activated through an extracellular electron injection effect, and the organic matter content and microbial activity of the soil are improved; and constructing a vegetation system, and planting alpine and saline-alkaline tolerant indigenous herbaceous and shrub plants. And the problem of ecological restoration of the high-altitude desert salinized area is solved.

The application discloses an open coal mine vegetation ecological restoration after maintenance system and method, including liquid storage shell, the side wall of liquid storage shell is equipped with lifting device, the horizontal surface of lifting device is provided with shunt pipe, the bottom of shunt pipe is communicated with a plurality of groups of hollow telescopic rod, the bottom of hollow telescopic rod is communicated with liquid outlet head, the rotation of shunt pipe is equipped with winding shaft, the outer wall of winding shaft is wound with a plurality of groups of pull rope, and one end of pull rope is connected with the moving end of hollow telescopic rod, the inner chamber of shunt pipe is equipped with driving mechanism, and one end of driving mechanism is in transmission connection with winding shaft. When the bush plant area is maintained, the driving mechanism drives the up-and-down movement of the liquid outlet head into the bush plant, not only effectively makes the pesticide liquid spraying cover on the outside of the bush plant, but also makes the pesticide sprayed by the liquid outlet head evenly cover the branches inside the bush plant, which is beneficial to the ecological restoration of the open coal mine.

The utility model discloses an ecological insect prevention buffer zone system based on plant communities, which is distributed in a strip shape around an area needing insect prevention, and the width is determined according to the scale of the area. In the buffer zone system, an arbor, shrub and grass dense planting area with the area not smaller than 100 square meters is built every two hectare to serve as a living organism dense inhabitation area, and the canopy density is 85% or above; arbor and herbaceous plants are arranged from the center to the edge in the horizontal direction of the living organism intensive inhabitation area, and bottom layer vegetation, middle layer vegetation and high layer vegetation are arranged from low to high in the vertical direction of the living organism intensive inhabitation area. Shrubs are planted between the two types of plants in the horizontal direction and between the bottom vegetation and the middle vegetation in the vertical direction; the plants have the effects of expelling insects and attracting natural enemies of the insects; at least one water body is arranged in the area of every two hectare. By means of multi-layer and multifunctional plant configuration, the natural prevention and control capacity of pests is enhanced, soil can be effectively improved, the ecological stability can be effectively enhanced, and reliable support is provided for achieving ecological agriculture.

The invention relates to a diterpenes type compound, a triterpenes type compound, a preparation method of the diterpenes type compound and the triterpenes type compound, and an application of the diterpenes type compound and the triterpenes type compound. The compounds 1 to 10 provided by the invention are novel diterpene and triterpene compounds which are obtained by extracting and separating from a vine shrub plant tripterygium wilfordii Hook.f. Of a winged euonymus tripterygium genus, and the novel diterpene and triterpene compounds are novel in structure, and the compounds 1 to 10 provided by the invention are novel diterpene and triterpene compounds which are obtained by extracting and separating from the vine shrub plant tripterygium wilfordii Hook.f. Of the winged euonymus tripterygium genus. Bioactivity experiments show that the compound 5 has significant ATP citrate lyase (ACLY) inhibitory activity, and has application potential in research and development of drugs for cancer, hyperlipidemia, atherosclerotic cardiovascular diseases and the like.

The invention discloses a microbial remediation method for metal sulfide mine waste ore. The microbial remediation method comprises the following steps: S1, screening indigenous sulfate reducing bacteria; s2, preparing a passivation material; s3, after the surface of the waste ore is flattened, a passivation material is laid; and S4, herbaceous plants and shrub plants are planted on the passivated material, and regular inspection is conducted till repairing is completed. According to the method, a microorganism and vegetation metal sulfide waste rock self-repairing system can be formed, acid production and heavy metal production of the waste rock can be inhibited, and long-acting stability of passivation of the waste rock in the metal sulfide mining area and ecological restoration is achieved.

This invention belongs to the field of ecological environment restoration technology and discloses a method for ecological restoration of grassland vegetation in photovoltaic power station areas in Gobi deserts. The method uses planted semi-shrubs as the core framework, employing micro-topography modification and seedling technology to effectively stabilize and improve gravelly soil, enhancing the stability of the topsoil structure. A specific ratio of mixed grass seeds is sown within a 15-30cm radius around the planted plants, forming a semi-shrub-herbaceous multi-layered structure. The complementary functions and vertical stratification of these two types of grasses promote stable community succession. Furthermore, the application of a specific ratio of organic fertilizer and water-retaining agent improves the soil at the bottom of the planting pit. This method not only avoids the waste associated with large-scale seed sowing but also significantly improves seedling emergence and survival rates, rapidly increasing vegetation coverage, reducing maintenance frequency and costs, and has broad application prospects in the ecological restoration of gravelly land.

The invention belongs to the technical field of prevention and control of invasive plant eupatorium adenophorum, and particularly discloses a preparation and ecological restoration method of a substitution prevention and control seed bag for eupatorium adenophorum invasive land, and particularly provides a seed bag which is composed of shrub plant species and herbaceous plant species, and the shrub plant species are acanthopanax, pistacia weinmannifolia, common melastoma herb and rice clover; the herbaceous plant species comprise carpet grass, bermuda grass and polygonatum kingianum.
