The invention discloses a method for controlling a desert through an artificial and biological crust and special lichen. The method provides a complete set of products for preparing lichen. The products consist of independently packaged fungus and algae, wherein the fungus is Endocarpon pusillum F07020 CGMCC No.3893 and the algae is Diplosphaera chodatii A07020 CGMCC No. 3892. The special lichen provided by the invention is lichen formed by the Endocarpon pusillum F07020 CGMCC No. 3893 and the Diplosphaera chodatii A07020 CGMCC No.3892. According to the method disclosed by the invention, the special lichen and / or the symbiotic fungus and the symbiotic algae of the lichen are scattered on the surface of sandy soil, a crust can be formed in one year and the overage rate of the crust per square meter can reach 80 percent. By adopting the method, the formation of the lichen crust can be directly promoted, the maturation time of the miniature biological crust is shortened, the operation issimple and convenient, the sand can be effectively and permanently fixed, the nutrient elements and the biological diversities of a desert ecosystem are improved, and the formed ecological landscape not only can bring economic values to the tourism of desert areas, but also can provide materials for the urban greening of arid and semiarid areas.

The invention discloses a water-retaining agent for desert greening, a preparation method and its application. The water-retaining agent for desert greening of the present invention has the advantages of being environmentally friendly, biodegradable, and does not pollute the soil. Starch and potassium fulvic acid are added. Greatly improved water absorption and saline-alkaline resistance, reduced production costs, can meet the needs of desertification control, and has high product application value; when preparing water-retaining agents, adjust the irradiation process, low-temperature gelatinization of starch alkali method, and use weak alkalinity Neutralizing agent, gel segmental drying, reducing energy consumption, improving radiation dose utilization and production efficiency; using the water-retaining agent of the present invention for desert greening and water retention, the grid can prevent sand and soil from moving, and strengthen the plant growth environment; organic matter The layer can supply carbon source, absorb excess water, and ventilate; the water-retaining layer can store water and fertilizer for plant growth and utilization; the synergy of the three measures can greatly improve the survival rate of seedlings planted in the desert.

The invention relates to a greening method for high and steep quartzite slopes in arid and rainless areas, which belongs to the field of regreening high and steep slopes. The method increases the aperture to 300mm in areas with less rainfall, but due to the high hardness of quartzite, the property is Brittle, serious wear and tear on the drilling rig, and the direct application of a 300mm-diameter drilling rig is costly and more difficult to construct. The method of the present invention uses a small-caliber drilling rig to drill three times in a triangle shape to complete the 300mm-diameter drilling. The cost is low, the time is short, and the construction difficulty is greatly reduced. , and more conducive to plant growth.

The invention discloses a dam fixing and protecting construction method using a soil stabilizer in a land reclamation project. The method comprises the steps of preparing a dry and hard mixture from the soil stabilizer, soil and water, and then compacting the mixture under a condition of supporting and protection of a template to form a scour prevention barrier wall. The scour prevention barrier wall prepared based on the method disclosed by the invention makes full use of local land and water resources, has a low requirement for soil quality and water quality, can neither affect planting on the surface land nor affect greening of a high and steep slope, can be used for 15 to 20 years, has an effect which is basically the same with that of a concrete barrier wall, and is pollution-free to the environment; the construction cost of the scour prevention barrier wall is only 1 / 3 of the cost of the concrete barrier wall, and the scour prevention barrier wall is relatively high in cost performance ratio; and the construction is relatively simple and convenient, and the construction cost is reduced. The method can be widely applied to land reclamation in the wide loess plateau and other sand and gravel-free districts as well as scour prevention of a steep side slope and a warp land dam, and has an important practical significance for healthy development of the land reclamation in mountainous areas.

The invention discloses a sand stabilizing and afforesting method. The method mainly includes the following steps of (1) arranging a sand-proof wall; (2) sequentially planning a forest zone, a meadow and a wind-and-solar complementary power station on the leeward side of the sand-proof wall; (3) constructing the wind-and-solar complementary power station; (4) digging a water well within any installation area for solar power generation modules. According to the sand stabilizing and afforesting method, an entirely excellent foundation structure of power generation equipment is provided, and is particularly applicable to construction of the wind-and-solar complementary power stations in marginal areas of deserts and gobi. Electrical energy generated by wind electricity and solar power is used for drawing water to irrigate forest regions and meadows, which is conducive to establishment of a stable ecological system in desertification regions. The systems involved in the sand stabilizing and afforesting scheme can run automatically, and can be applied to collection of renewable energy and environmental governance in the desertification regions.

The invention belongs to the field of new environment-friendly materials, and relates to a method for preventing and treating desertization by fungus-based biomass materials and application of the method. The method includes cultivation raw material preparation, hypha block preparation, filling mold cultivation, product formation, and treatment for wind prevention and sand fixation. The method andthe application thereof have the advantages that the manufacture process of the obtained biomass materials is simple and convenient, and the obtained biomass materials have ecological environment protection effect, high water-absorbing and water-holding capabilities, high sand stabilization capability and high degradation property; organic fertilizer obtained after degradation can improve desertelements and provide long-term nutrition to plant growth, and accordingly, desert greening is achieved finally; broad market prospect and high economic value are realized.

The invention discloses a laying equipment for ecological environment restoration, desertification control and greening, which comprises a tractor head, a sand barrier piling and laying mechanism, a sleeve grabbing mechanism and a sand barrier assembly. The sand barrier assembly includes a pair of gauze device on the sandy ground; the diagonal vertical sleeve adopts a magnetic material sleeve; The left and right sides of the frame base plate are respectively equipped with a fixed sand barrier storage rack, a feeding and pushing device for pushing the fixed piles to move longitudinally along the sand barrier storage rack, and a piling guide for driving the fixed piles into the sand in sequence device. The structure design of the sand barrier assembly in the present invention is reasonable, the structure is stable and reliable, which is beneficial to the later stage of sand prevention and sand fixation, and is also convenient for disassembly and later recycling; the use of mechanized operations can better overcome the harsh natural environment of the desert, and it is more effective in controlling sandstorms. Being able to seize the opportunity is conducive to defending the environment on which human beings depend for survival.
