Abstract

The utility model discloses a plant planting system for a saline-alkaline land. The plant planting system comprises planting furrows (6) formed in the saline-alkaline soil, the interior of each planting furrow (6) is filled with a breathable impermeable layer (1) and a planting soil layer (5) from bottom to top, sidewalls (7) of the planting furrows are waterproof sidewalls, and a breathable impermeable protection layer (4) is arranged between each breathable impermeable layer (1) and the corresponding planting soil layer (5). By the aid of the breathable impermeable protection layer, root systems of plants in the plant soil layers can be prevented from extending downwards to break the breathable impermeable layers, so that the breathable impermeable layers are protected against impermeability ineffectiveness when the breathable impermeable layers are destroyed by the root systems of the plants.

Description

A kind of saline land plant planting system

Technical field

The utility model relates to a kind of plant planting system, specifically, relates to a kind of implant system that is suitable for plant growth in saline land.

Background technology

Saline land refers to the soil that soil contains excessive solubility salt, the reason of saline Land is because soil and groundwater saliferous is too high, under strong surface evaporation effect, underground shallow layer water is transported to earth's surface through capillary and is evaporated, capillary is in the process of earth's surface water delivery, also the salinity in water is taken to earth's surface, after water is evaporated, soil salt rises by capillarity and accumulates in upper soll layer, salinity has just been stayed in earth's surface and ground thin solum, the salinity of accumulation is many like this, there is no again enough fresh water dilutions and drained, just formed the salinization of soil.Saline and alkaline is large or idle because of salt content in the saline land more than 0.3%, below 0.8%, or is utilized reluctantly, is utilized reluctantly, and its output is also very low, and economic benefit is bad.

At present, both at home and abroad the processing method in saline land is generally comprised salt discharge method and presses salt method, but they all exist many weak points, salt discharge method is by using a large amount of fresh water to rinse for a long time saline land, to make the salt content on surface, saline land reduce, pressing salt method is to utilize natural precipitation or artificial flood to irrigate, impel the infiltration downwards such as the saline and alkaline hole along soil of part, crack, the salinity of topsoil is brought to bottom with water.Although said method can make the salt content on top layer, saline land reduce, and can not keep permanent, and needs a large amount of water sources.

For this reason, Chinese patent literature CN102232328A discloses a kind of method in saline land and implantation methods in saline land improved, the method is got rid of saline and alkaline topsoil, gas permeability antiseepage aggregate layer is set on the saline land of having removed topsoil, on described gas permeability antiseepage aggregate layer, plantation soil layer is set, then planting plants on kind of fill stratum.The method has prevented that at the planting initial stage top layer kind fill stratum is by salination effectively, but along with the growth shape of plant is large, root system can be more and more in depth to underground growth, after certain hour, root system can penetrate plantation soil layer to gas permeability antiseepage aggregate layer deeply, thereby has destroyed the structure of permeable antiseepage aggregate layer, make to alter on Underground Salt buck, and then destroy the growth of plant, and cause plant dead, cause previous work to be fallen short of success for lack of final effort.

Utility model content

For solving in prior art, gas permeability antiseepage aggregate layer is easy to be made the problem of altering on Underground Salt buck by root system of plant destruction, and then a kind of plant planting system that is suitable for saline land plant long term growth is provided.

For this reason, the technical scheme that the utility model is taked is:

A kind of saline land plant planting system, comprise the plantation ditch being arranged in saline land, the inside of described plantation ditch is filled with ventilation anti-seepage layer and plantation soil layer from bottom to top, wherein, the sidewall of described plantation ditch is waterproof sidewall, and described ventilation anti-seepage layer and planting soil interlayer are also provided with ventilation anti-seepage overcoat.

In the plant planting system of above-mentioned saline land, described plantation ditch be arranged in parallel.

In the plant planting system of above-mentioned saline land, described ventilation anti-seepage overcoat is water-permeable brick layer.

In the plant planting system of above-mentioned saline land, between described ventilation anti-seepage overcoat and described ventilation anti-seepage layer, be also provided with reservoir bed.

In the plant planting system of above-mentioned saline land, described reservoir bed is fine earth and/or sand layer.

In the plant planting system of above-mentioned saline land, described ventilation anti-seepage layer is ventilation anti-seepage sand bed.

In the plant planting system of above-mentioned saline land, described plantation soil layer is soil moved in to improve the original layer or saline and alkaline soil layer.

In the plant planting system of above-mentioned saline land, the gross thickness of actual each layer of filling (for example ventilation anti-seepage layer, reservoir bed, ventilation anti-seepage overcoat and plant soil layer) is not less than the degree of depth of described plantation ditch, thereby makes the upper surface of described plantation soil layer be not less than the ground in described saline land.

Compared with prior art, the utlity model has following advantage:

(1) saline land of the present utility model plant planting system also includes ventilation anti-seepage overcoat, described ventilation anti-seepage overcoat can stop the root system of plant in plantation soil layer to destroy ventilation anti-seepage layer to downward-extension, thereby has avoided ventilation anti-seepage layer to be destroyed and then lose anti-seepage effect by the root system of plant.

(2) in the plant planting system of saline land of the present utility model, the hard quality of described water-permeable brick layer not only can stop the root system of plant in plantation soil layer to destroy ventilation anti-seepage layer to downward-extension, can also in water-permeable brick, conserve a part by the water oozing under upper strata plantation soil layer, externally during drought, the water of water-permeable brick, for supply root system of plant, meets the required moisture of plant growth.

(3) saline land of the present utility model plant planting system is also provided with reservoir bed, described reservoir bed be fine earth layer, sand layer or by fine earth and sand mixture, formed layer, one of its effect is to store moisture content, externally during drought, water in reservoir bed makes progress evaporative fill to root system of plant, meet the required moisture of plant growth, also play the effect of levelling simultaneously, for laying upper strata, prepare.

(4) in the plant planting system of saline land of the present utility model, plant soil layer and can lay soil moved in to improve the original layer according to actual conditions, also can be laid in saline and alkaline soil layer, due to ventilation anti-seepage layer effectively stoped Underground Salt buck on alter, when plantation soil layer is saline and alkaline soil layer, on it, salt plant is inhaled in plantation, thereby realizes the improvement to saline-alkali soil, reduces the expense that soil moved in to improve the original brings, cost is reduced, and reduces the waste of soil resource; Yet directly lay soil moved in to improve the original layer, just can see planting effect then, as flower growth is good, economic crops obtain output.

(5) this implant system length and width can be fixed according to actual conditions, there is no the restriction of too many factor own, simple to operate flexible; The ventilation anti-seepage layer of laying is not destroyed, and can intercept for a long time saline and alkaline.
