The invention relates to a method for planting trees in a desert environment. The method includes steps of a, laying mulching films on side walls and bottoms of planting holes; b, soaking all parts of roots of the trees in rooting powder solution and then placing the roots of the trees in the planting holes; c, filling grass carbon soil and earth surface soil mixtures into the planting holes; and d, enclosing the trees by barrages and watering the trees. Tree species suitable to grow in the desert environment are selected to mainly solve the problem of low survival rate of nursery trees in the desert environment, and the trees are planted in different locations of a desert according to characteristics of the different tree species, so that survival of the trees is guaranteed, the characteristics of the trees are sufficiently played, the trees can normally grow, the characteristics of sand prevention and water retention of the trees can be played, and the method has the advantages of simplicity, wide material source, low manufacturing cost and high survival rate of nursery trees.

The invention discloses a pattern for building artificial algal crust in a desert, which includes: subjecting hybrid algae in natural algal crust in Gurbantunggut Desert of Xinjiang to liquid culture, transferring the algae into a greenhouse for propagation and domestication, and finally inoculating domesticated algae stock to field deserts to generate artificial algal crust, wherein one liter of liquid culture medium contains 2.5g of (NH4)2HPO4, 0.07g of MgSO4X7H2O, 0.036g of CaC12X2H2O, 0.006g of citric acid, 0.006g of ferric citric amine, 0.001g of ethylenediamine tetraacetic acid sodium, 0.02g of CaCO3, 1mL of trace element A5 solution, and 40mL of soil extract. By using the hybrid algae for inoculation, the process of purification and separation is omitted, culturing speed is high, manpower and material resources are reduced, and important practical value is achieved.

The invention discloses a binary star eight-wheel lunar vehicle, which comprises a binary star vehicle body structure, a coordination control system, a driving system, a steering system, an eight-wheel arm coordination vertical telescopic moving system, an image pick-up and infrared temperature and humidity detection system, a remote monitoring and control system and a mixed energy source supply system, wherein the stability and the operability of the control system are high, the energy utilization rate is high, the motive power is strong, the maneuverability and the flexibility are high, the environment is protected, the energy is saved, and duplex walking systems are adopted. The binary star eight-wheel lunar vehicle has the advantages that each kind of unique mechanism and control system improves the adaptation capability of the vehicle and can be used as a lunar vehicle walking system; the excellent flexibility is realized, the driving force is strong, and the binary star eight-wheel lunar vehicle can adapt to desert environment; the relative position can be regulated in a certain space through the binary star vehicle body structure, the flexibility of a vehicle body is improved to a great degree, and the binary star eight-wheel lunar vehicle can be applied to a special heavy-weight-class transportation vehicle.

A semi-continuous duty, Green Technology, self-charging 14, unmanned electric vehicle providing protection and security from underground mines. A deflector blade 11 follows natural existing contours to maintain straight line paths, while simultaneously carrying a mine detector 10, a vertical reciprocating ram set 30, 32 and 33 that preloads soil while also creating forward motion, followed by an energy dissipation and containment canopy system 22, 24, 26&29. The comprehensive system provides protection from mines on existing pathways in desert environments using a self-sufficient energy source. In addition, the total system utilizes only Green Technology for all modes of operation.

The invention discloses an overhead door for a compartment type rescue vehicle, comprising a door body, wherein the lower end of the door body is provided with a hinging device, and the hinging device is used for connecting with a base plate arranged at the back end of a compartment of the compartment type rescue vehicle; and the vehicle head direction of the compartment type rescue vehicle is taken as the forward direction, plate reversing grooves are respectively and symmetrically arranged at the back surface of the door body left and right, each plate reversing groove is internally provided with a reversing plate, the top ends of the reversing plates are hinged in the plate reversing grooves. According to the overhead door for the compartment type rescue vehicle, the compartment vehicle is also suitable for transporting the vehicle, so that the vehicle to be transported can be effectively protected by the compartment when being transported, and the damage or the pollution of the vehicle when the vehicle is transported can be avoided, therefore, the overhead door is specially suitable for transporting the expensive vehicle such as the racing vehicle, and particularly suitable for the vehicle rescue and transportation under the desert environment. The length of an inclined lane is lengthened after the reversing plates are outwards rotated, so that the inclined lane is less in gradient when the vehicle is loaded or unloaded, and the passing requirement of the low-chassis vehicle such as the racing vehicle can be met, therefore, the racing vehicle can be conveniently and quickly loaded and unloaded. According to the overhead door, the loading / unloading operation can be simplified, the labor intensity when the vehicle is loaded and unloaded can be reduced, and the loading / unloading efficiency can be improved.

The invention discloses a desert control method of a chemical sand-fixing greening technology based on organic composite materials, and the desert control method is characterized in that hydrophilic polyurethane resin curing agent solution is sprayed on a sand or soil layer of greening objects for sowing the vegetation for forming a porous fixed sand layer. The fixed sand layer formed by the method has appropriate thickness and strength, good durability, good anti-freeze and melt properties and functions of water retention, thermal insulation, ventilation, vegetation and the like. According tothe method of the invention, the stable and effective solidifying can be carried out on sand even under the specific desert environments of no abundant groundwater sources and strong wind erosion, and the purpose of vegetation greening can be also realized. The method has large-scale construction properties and good economic performances, thereby being applicable to the needs of large-scale chemical sand fixing and vegetation greening of the vast desert and realizing the plant greening function and the ecological restoration and the control of desertified land.
