The grapes are one of the fruit tree types which are developed most rapidly and have the best production benefit in the north of China, and are also high-efficiency industries which are mainly supported and developed by governments. By 2018, the grape planting area in Shaanxi province reaches 70.3 ten thousand mu, the yield is 82.8 ten thousand tons, the average yield per unit is 1.18 tons/mu, and the total yield exceeds 50 hundred million yuan. The grape industry plays an important role in improving per capita income and performing poverty elimination and hardness elimination.
Gansu and Shaanbei are one of the important grape producing areas in China, and under the influence of cold weather in winter in the areas, grape plants are extremely easy to suffer from freeze injury in winter, so that the overall yield of grapes is reduced, the quality of berry fruits is poor, and the death of the entire grape plants can be caused in severe cases. At present, fruit growers basically cover grapes by burying soil to prevent cold and preserve heat. However, the soil burying measures are time-consuming and labor-consuming, the economic cost is high, branch damage is easily caused in the soil burying process to influence the growth vigor and the yield of grapes in the next year, the temperature cannot be accurately controlled, and the grapes may be frostbitten or germinate in advance. In addition, in these areas, wind erosion is severe in winter, and soil burying measures disturb the surface layer of soil, so that the wind resistance is weakened, and the soil wind erosion is aggravated.
Therefore, the existing soil burying measures which are widely applied can cause serious wind erosion, reduce the local soil fertility, reduce the yield of the grapes and have the effect of influencing the quality of the grapes. The research on the soil-free overwintering water and soil conservation technology of the grapes can ensure that the grapes can safely overwinter and control wind erosion, and has important significance for grape industry development and wind erosion treatment.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model aims at designing a prevent wind heat retaining novel adjustable air cavity cover body and be used for the management of surviving the winter of grape lower rack to solve that the amount of labour that exists is big, the investment is big among the current grape soil-buried overwintering measure, big and easily take place harm such as wind erosion to soil disturbance.
In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
Referring to fig. 1 and 2, an adjustable air cavity covering body for grape soil-buried overwintering comprises a heat insulation cavity base layer 1 and a heat insulation cavity expandable layer 2, wherein a cavity formed by welding the base layer and the cavity layer is an adjustable cavity, and the cavities are relatively sealed; the adjustment of the cavity is realized by the inflation and air exhaust of the inflation and air exhaust valve 3; and a fixing device 4.
The heat insulation cavity base layer 1 is arranged on the uppermost layer and is a complete air-impermeable film, such as a plastic film, a plastic film and the like.
The expandable layer 2 material of the heat insulation cavity is consistent with the basic layer, the width is taken as the value of the cavity, and the thickness of the specific cavity can be adjusted according to the heat insulation requirements of each area or land block in order to adapt to different weather conditions and keep the surface temperature constant. For example, 30cm is taken and welded on the base layer of the heat insulation cavity, the welding parts of the two cavity layers are overlapped, and the air charging and exhausting valve 3 is not welded with the base layer at the position to form the vent hole. Each air cavity is independent, and even if one air cavity is damaged, the work of other cavities is not influenced, so that the heat preservation effect is not influenced. The heat insulation cavity is inflated and deflated according to requirements during working so as to control the thickness of the cavity and achieve the heat insulation effect. In daytime, the plastic film absorbs heat and stores the heat in the soil, increasing the surface temperature. When the temperature is reduced at night, the soil releases heat, the heat insulation cavity plays a role in separating heat exchange, and the ground surface temperature is kept. The heat insulation cavity is flat under the non-inflation state, and can be folded, stored and managed like a common mulching film when not in use, so that the actual usability of the mulching film is increased.
The air inflation and extraction valve 3 is a two-way air valve used for inflating and exhausting the cavity of the heat insulation cavity. Inflation and deflation may be accomplished by manual air cylinders, electric air pumps, and the like.
The fixing device 4 is welded on the heat insulation cavity base layer and used for fixing the adjustable air cavity covering body and reducing the problem of grape branch freezing injury or water loss caused by insufficient contact between the covering body and the ground surface due to wind power and the like.
The utility model discloses the principle and the implementation mode of the utility model are explained by applying the concrete examples, and the explanation of the above examples is only used for helping to understand the method and the core idea of the utility model; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the concrete implementation and the application scope. In summary, the content of the present description should not be construed as a limitation of the present invention.
