The salt-resistant enclosing wall with the design can be used for blocking the circulation of water and salt in soil in the planting area and surrounding soil, the soil after salt washing is not easy to return salt, and meanwhile, water storage cavities formed in the salt-resistant enclosing wall can be used for carrying out drip irrigation on the planting area.
The top that the aforesaid hinders salt enclosure is just to being provided with two rainwater collection swash plates, two the rainwater is collected the swash plate and is "eight" font setting, two the lower limb that the swash plate was collected to the rainwater be close to each other and respectively with the top edge connection that hinders the salt enclosure, two the rainwater is collected the swash plate and is hindered the roof of salt enclosure and encloses into the ponding recess, and this ponding recess is followed the length direction who hinders the salt enclosure sets up, and this ponding recess is through seting up at least one rainwater of its tank bottom from the discharge orifice with correspond the water storage chamber intercommunication. Adopt this scheme to collect the rainwater that the swash plate was collected through the rainwater in the rainfall season, the rainwater collects and flows into the water storage chamber through the rainwater self-flowing hole further behind the ponding recess, has saved the irrigation water demand.
Above-mentioned rainwater is from flowing hole top and is equipped with anti-evaporation pad, should prevent that evaporation pad is including preventing the evaporation packing ring, prevent the lower surface of evaporation packing ring with the tank bottom laminating of ponding recess, the inner edge of preventing the evaporation packing ring is connected with the location bushing pipe, and this location bushing pipe stretches into downwards rainwater is from flowing hole covers elastic valve on the location bushing pipe, be equipped with rainwater from flowing the mouth on the elastic valve. When the scheme is adopted, moisture collected in the water accumulation groove can prop open the elastic valve to automatically flow into the water storage cavity under the action of gravity, and the elastic valve can rebound to seal the rainwater self-flow hole to avoid moisture evaporation in the water storage cavity when the rain falls.
The lower surface of above-mentioned elastic valve pastes tightly with the upper surface of anti-evaporation gasket, the rainwater is from the mouth of flowing in for "ten" font incision, and this "ten" font incision is located directly over the rainwater is from the discharge orifice, the outer wall of location bushing pipe with the rainwater is from the inner wall laminating in discharge orifice the elastic valve top is fixed with the valve supporting network, has laid one deck gravel layer in the ponding recess of valve supporting network top. Adopt this scheme to play the effect that the location supported through valve supporting network to elastic valve, prevent that elastic valve from collapsing because of the rainwater that the upper strata collects is too much, the gravel layer compresses tightly valve supporting network and valve, and the two takes place to drift when preventing ponding too much, and certain filtering action still can be played on the gravel layer simultaneously, prevents that silt from getting into the water storage chamber along with the rainwater, causes the siltation in water storage chamber, causes the water storage volume to diminish.

By adopting the design, the salt permeation and salt blocking enclosing wall in the soil outside the planting area can be effectively prevented from entering the water storage cavity and even entering the soil inside the planting area, and the blocking effect on the salt is better.
The salt-resistant waterproof layer comprises two layers of PVC films, a nylon wire mesh is clamped between the two layers of PVC films, the two layers of PVC films are thermally sealed into a whole through a heat sealing machine, and the nylon wire mesh is fixed between the two layers of PVC films. Adopt degradable PVC film, at the plant in-process of planting improvement desert, the PVC film constantly degrades, and the hole in the inside nylon wire net of root system accessible PVC membrane of plant constantly grows downwards, and nylon wire net still can play fixed root system's effect to the plant of planting simultaneously, prevents that the plant from being blown down by the wind.
Each salt blocking enclosing wall is provided with a plurality of vent holes. When the design is adopted and the wind is great in the desert, the air can be rapidly discharged out through convection from the vent holes, and the salt-blocking enclosing wall is prevented from toppling over due to too great wind resistance.
Has the beneficial effects that: because laid in planting district soil below and hindered the salt waterproof layer consequently can effectively avoid returning the salt-washing soil on upper strata along with the moisture evaporation in the lower floor soil in the less season of rainfall, collect the rainwater through rainwater collection device and irrigate with the rethread drip irrigation pipe after getting up the storage, ensure that the soil after the salt-washing keeps the crops that certain moisture was planted and is unlikely to dry up and die, consequently can directly be absorbed by the crop from the moisture that drips irrigation pipe and spill over because drip irrigation pipe just is located the furrow below of planting the crop, the evaporation of having avoided moisture is extravagant.
