Abstract
The invention discloses a plant planting system for saline-alkaline soil. 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 caused by destroying of the root systems of the plants.
Description
Technical field
The present invention relates to a kind of plant planting system, specifically, relate to a kind of implant system being suitable for plant growth in saline land.
Background technology
Saline land refers to that soil contains the soil of excess soluble 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 is risen by capillarity and accumulates in upper soll layer, salinity has just been stayed in earth's surface and ground thin solum, the salinity of such accumulation is many, there is no again enough fresh water dilutions and drained, just define the salinization of soil.Saline and alkaline more than 0.3%, the saline land of less than 0.8% because salt content is large or idle, or utilized reluctantly, utilized reluctantly, its output is also very low, and economic benefit is bad.
At present, salt discharge method and pressure salt method are generally comprised to the processing method in saline land both at home and abroad, but they all also exist many weak points, salt discharge method by using a large amount of fresh water to rinse for a long time saline land, the salt content on surface, saline land is reduced, pressure salt method utilizes natural precipitation or artificial flood to irrigate, impel the infiltration downwards such as the saline and alkaline hole along soil of part, crack, by the salinity of topsoil with water-band to bottom.Although said method can make the salt content on top layer, saline land reduce, it is permanent to keep, and needs a large amount of water sources.
For this reason, Chinese patent literature CN102232328A discloses and a kind ofly improves the method in saline land and the implantation methods in saline land, saline and alkaline topsoil is got rid of by the method, the saline land eliminating topsoil arranges gas permeability antiseepage aggregate layer, described gas permeability antiseepage aggregate layer arranges plantation soil layer, then planting plants on kind of fill stratum.The method effectively prevent top layer kind fill stratum by salination at the planting initial stage, but along with the growth shape of plant is large, root system can more and more in depth grow to underground, after certain hour, root system can penetrate plantation soil layer to gas permeability antiseepage aggregate layer deeply, thus destroys the structure of permeable antiseepage aggregate layer, make Underground Salt buck is altered, and then destroy the growth of plant, cause Plant death, cause previous work to be fallen short of success for lack of final effort.
Summary of the invention
For solving in prior art, gas permeability antiseepage aggregate layer is easy to be destroyed by root system of plant the problem making Underground Salt buck is altered, and then provides a kind of plant planting system being suitable for saline land plant long term growth.
For this reason, the technical scheme that the present invention takes is:
A kind of saline land plant planting system, comprise the plantation ditch be 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 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 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 (such as ventilation anti-seepage layer, reservoir bed, ventilation anti-seepage overcoat and plantation soil layer) of filling is not less than the degree of depth of described plantation ditch, thus makes the upper surface of described plantation soil layer be not less than the ground in described saline land.
Compared with prior art, tool of the present invention has the following advantages:
(1) saline land of the present invention 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, thus avoids ventilation anti-seepage layer and destroyed by the root system of plant and then lose anti-seepage effect.
(2) in the plant planting system of saline land of the present invention, the quality that described permeable brick layer is hard not only can stop the root system of plant in plantation soil layer to destroy ventilation anti-seepage layer to downward-extension, the water oozed under a part plants soil layer by upper strata can also be conserved in water-permeable brick, when outside drought, the water of water-permeable brick is used for supply root system of plant, meets the moisture needed for plant growth.
(3) saline land of the present invention plant planting system is also provided with reservoir bed, described reservoir bed is fine earth layer, sand layer or the layer that formed by fine earth and sand mixture, one of its effect stores moisture content, when outside drought, water in reservoir bed upwards evaporative fill to root system of plant, meeting the moisture needed for plant growth, also play levelling effect simultaneously, preparing for laying upper strata.
(4) plant soil layer in the plant planting system of saline land of the present invention and can lay soil moved in improve the original layer according to actual conditions, also saline and alkaline soil layer can be laid in, due to ventilation anti-seepage layer effectively prevent Underground Salt buck on alter, when plantation soil layer is saline and alkaline soil layer, on it, salt plant is inhaled in plantation, thus realizes the improvement to saline-alkali soil, reduces the expense that soil moved in improve the original brings, cost is reduced, and reduces the waste of soil resource; But directly lay soil moved in 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, do not have the restriction of too many factor own, flexibly simple to operate; The ventilation anti-seepage layer laid is not destroyed, and can intercept saline and alkaline for a long time.
