In a water-deficient region, a thermal insulation material and condensed water produced by a temperature difference generated in a refrigeration process are used for gradually increasing the moisture of soil. A cooling air water-collecting system is adopted, power is supplied to a refrigeration device by renewable energy sources such as solar energy or wind power, moisture is obtained from wet air through a refrigeration dewing method, and the condensed water is introduced into the soil through a water delivery pipe; moreover, a rock wool board is paved on the surface of the soil, so that evaporation of moisture on the surface of the soil is reduced or prevented, water is injected into the soil by continuously absorbing air moisture, the water accumulating function of the soil is added, and the moisture of the soil is further increased.
Description
Technical field
The present invention relates to a kind of improve arid, the technical field of semiarid zone soil moisture；Specifically related to a kind of increase
The system of Arid＆semi-arid area soil moisture.
Background technology
The barren soil of dry soil fertility occupies very large area, and in China, at least hundred million mu of ground of 3-4 water source is deficient lacks, soil
, less than 50 centimetres, content of organics is very low for layer low thickness.In world wide, central africa, South America western part, northern and Ya Zhouxi
Also vegetation sparse, river are rare mostly along overseas whole hinterland for Asia, the Central Asia, Australia.Raise with temperature, snow line
Upper shifting, Melting Glacierss, strong wind, the extreme climate frequency of occurrences such as extremely hot dramatically increase and much regional desertification arid expand
Gesture.Much regional severe water and soil erosion, grain drop in production, the frequent sandstorm of disaster and haze have become the normality in life.
In arid area, Groundwater buried depth is deeper, and soil evaporativeness is big, and rainwater is rare.Improvement fine sand desert, semidesert are
The problem that a lot of countries and regions are carried out.Due to weather conditions and geographical conditions, increase the method such as rain and river diversion and be difficult to prove effective.
It is the extremely valuable new thinking that current scientific and technological circle have an optimistic view of to arid area " coating ".The method adopting now is mainly in sand
Unconcerned surface spraying fixes the sand cement mortar masonry cement concrete hurdle dam, reclaims waste plastics processing grid spraying water-absorbing resin etc..As in
Report a kind of method of Desert Control in state's patent application (cn105369793a), technical scheme predominantly by cement plus water with become
Cement mortar, is sprayed on desert surface, because the grains of sand are dried, makes the cement mortar rapid solidification of spraying, forms cement mortar cover layer,
Shifting-sand fixation, arranges planting hole on cement mortar cover layer, tree, grass is sowed in planting hole, covering cement layer is solid drift sand
Fixed, make not blowing away sand, enable tree, grass to take root desert, cement mortar cover layer forms layer protecting film in desert surface, makes sand
Subsoil water in desert will not be evaporated by the sun, makes tree, grass have moisture smooth growth.These measures obtain certain effect, but also have
Certain limitation.After cement concrete covers, desert cannot be cultivated, unfavorable soil improvement.Easily caused secondary using plastic
Pollution；Solidify high expensive with waterglass, and there is no what effect.
