Unless otherwise indicated, numerical ranges herein include not only the entire range within its two endpoints, but also several sub-ranges subsumed therein.

The tree overwintering protection is quite common in northern and northwest areas of China, and mainly comprises tree binding, such as the creation of superior small environment by wrapping plant branches or wrapping the whole plant with plastic films and green canvases by using straw ropes, plastic cloth, cotton curtains and the like to help the plants to overwinter; the tree branches and trunks are coated with the white paint, and the characteristics of less white absorbed heat and slow heat dissipation are utilized, so that the absorption of the tree trunks on solar radiation heat is reduced, the barks are prevented from being damaged by low-temperature sunburn, and the plant diseases and insect pests can be prevented and treated; spraying irrigation antifreezing solution, and freezing water for nursery stocks; pruning all the seedlings planted in late autumn and early winter, wherein the pruning is mainly carried out on diseased and insect branches and weak branches which are poor in development and low in lignification degree; pruning hedgerow and bulb tree, reducing the surface area of the planting nursery stock, reducing the evaporation of water in the body and enhancing the cold resistance and overwintering capability; building a wind barrier around the nursery stock by using plastic cloth or a sunshade net to improve the temperature around the tree body; plastic cloth or straw curtain is laid on the ground to cover and prevent cold, etc. The overwintering measures are widely used in inland areas in the north and the northwest of China, and related researches are frequently reported.

However, the environment of the Qinghai-Tibet plateau in China is severe, and the trees are difficult to grow in the region under severe environments such as severe cold, high altitude, strong wind and the like, and when newly planted and transplanted trees are overwintering, the plants are frozen and drained to die due to long duration in winter, low temperature and other factors, so that the death rate of the trees is increased, and the conventional overwintering measures in inland regions cannot play a perfect overwintering protection role in the severe cold and high altitude regions.

The application provides a plant device of wintering in severe cold high-altitude area, as shown in fig. 1, including protecting wall 1 and vegetable layer 4, protecting wall 1 buries underground in soil and forms the top for open-ended closed structure protecting wall 1's middle part is formed with protection zone 2, vegetable layer 4 is located in protection zone 2 and with protecting wall 1 interval sets up still be equipped with protective layer 3 in the protection zone 2, protective layer 3 will vegetable layer 4 covers and with protecting wall 1's lateral wall sets up for the border, is used for avoiding vegetable layer 4 takes place to die because of reasons such as chilliness, arid or sunlight firing.

Optionally, the protective layer 3 may be a snow accumulation layer formed by artificial snowfall, that is, snow is collected by a snowmaker in the protective area 2 by using an artificial snowfall method, the thickness of the snow accumulation layer may be 0.5-0.7m, and the vegetation layer 4 is fully covered or half covered. The principle of artificial snowfall is that water is injected into a special nozzle or spray gun and contacts with high-pressure air, the high-pressure air divides water flow into tiny particles and sprays the tiny particles into cold outside air, and the tiny particles are condensed into ice crystals to form snowflakes before falling to the ground.

Alternatively, the vegetation layer 4 may be a vegetation layer 4 formed of plants such as low shrubs or hedges.

The snow layer has the effects of heat preservation, moisture preservation, ventilation and sunburn prevention, firstly, snow has poor heat conductivity, and the snow layer covers the soil surface, so that the heat of the soil can be reduced from being transmitted outwards, and cold air in the air is prevented from entering the vegetation layer 4; the porosity among the snowflakes is high, the air permeability is good, and the growth of plants cannot be hindered; the air is bad conductor, and the heat conductivity is poor, and air creeps into in the snow hole, can protect ground temperature can not drop very low, consequently the snow layer has fine heat preservation ventilation effect to help the plant overwintering.

Secondly, the snow layer is slowly melted, most of the snow layer can permeate into the soil during melting and is stored and not easy to run off, so that the soil humidity of the plant root system can be improved; the snow layer can improve the humidity around the plants by sublimation; the snow layer can reduce the evaporation of soil moisture; the snow layer can isolate wind, thereby avoiding the stem of the plant from being blown through by strong wind to cause the physiological drainage of the plant, ensuring that the soil moisture content is good when the plant is thawed, and being very beneficial to the growth of the plant.

Finally, the sunlight radiation in the alpine and high-altitude areas is strong, the plant base and the sunny side of the plant are easily affected by the sunlight radiation and the temperature fluctuation, the temperature rises after the sunlight is directly radiated, the frozen cambium is rapidly melted and dehydrated, the temperature is reduced at night, the cambium is frozen, the cambium is necrotic due to the alternation of freeze thawing, and the direct radiation of the sunlight to the ground and the bark is blocked by covering the trunk with the snow layer, so that the freeze thawing phenomenon is reduced, and the sunburning problem of the plant is solved.

In addition, protection wall 1 can slow down wind-force, and it is right to alleviate strong wind the influence of vegetable layer 4 can control the snow deposit in certain extent simultaneously, avoids snow to be blown away by strong wind effectively and causes the reduction of snow deposit and the guard time shorten scheduling problem, sheltering from and covering on snow deposit has further helped vegetable layer 4 completely cuts off wind-force to can effectively separate the incomplete of the destruction of wind to the plant, avoid the plant to break and lose the lodging.

The utility model provides a device of surviving winter of plant in alpine and high-altitude area protects tegument 4 through protection wall 1 and protective layer 3, can reduce the plant and receive temperature, humidity and sunshine's influence in alpine and high-altitude area, ensures the plant safety and overwinter, has improved the survival rate of surviving winter of plant, has opened the new thinking that can the whole protection of large tracts of land after relay, the line protection to still have advantages such as the simple cost of construction is low.
