Embodiment 1

[0041] like figure 1 As shown, the saline-alkali plant planting system of the present invention includes 6 planting ditches 6 arranged in parallel at intervals of 1m in the saline-alkali land, and the side walls 7 of the planting ditches 6 are waterproof side walls, and the waterproof side walls are excavated. After planting ditch 6, stick plastic cloth on its side wall to form, to prevent the saline-alkali water outside planting ditch 6 from infiltrating planting ditch 6 by its side wall 7. In the planting ditch 6, three water collection wells 9 are arranged at intervals along its length direction, and the walls of the water collection wells 9 are made of water-permeable materials. Inside; figure 2 It is a schematic cross-sectional view of a planting ditch perpendicular to its length direction of the present invention, as figure 2As shown, the inside of the planting ditch 6 is filled with a 1cm thick breathable anti-seepage layer 1, a 0.5cm thick protective layer 2, a 10c...

Embodiment 2

[0046] like Figure 5 As shown, the structure of the planting ditch in this embodiment is basically the same as that of the planting ditch in Example 1, the only difference being that the bottom surface of the planting ditch 6, the breathable anti-seepage layer 1 and the protective layer 2 are all parallel to the horizontal plane, and the leveling layer 3 is laid along its width direction in a manner of gradually decreasing thickness, so that the surface of the leveling layer 3 in contact with the protective layer 4 is inclined, and the protective layer 5 is laid along the The surface (the surface where the leveling layer 3 is in contact with the protective layer 4) is laid in parallel, so that the planting soil layer 5 has an inclined bottom surface.

Embodiment 3

[0048] like Image 6 As shown, the structure of the planting ditch in this embodiment is basically the same as the structure of the planting ditch in Example 1, the only difference is that the planting soil layer 5 is set as a partially inclined bottom surface, and the air-permeable anti-seepage layer 1 , the protection layer 2, the leveling layer 3, and the protection layer 4 extend to the side wall of the planting ditch along the width direction of the planting ditch parallel to the horizontal plane at the low end of each layer, thereby dividing each layer into an inclined part and a The horizontal part, the water collection well 9 is located above the horizontal part of the protection layer 4 .

Abstract

The invention discloses an improved saline-alkali soil plant cropping system, comprising a cropping ditch arranged in saline-alkali soil, wherein the cropping ditch is internally filled with a ventilation impermeable layer, a covering layer, a leveling layer, a protective layer and a cropping soil layer from bottom to top, the side wall of the cropping ditch is a waterproof side wall, the cropping ditch is internally provided with a plurality of water-collecting wells at intervals along the length direction of the cropping ditch, each water-collecting well is provided with a permeable well wall made of a permeable material, the bottom of each water-collecting well is positioned in the cropping soil layer, and further at least the partial bottom, contacted with the protective layer, of the cropping soil layer forms an included angle with the horizontal plane. According to the improved saline-alkali soil plant cropping system, water in the cropping soil layer flows into the water-collecting wells along the gradient; when rainfall is abundant, the water in the water-collecting wells is pumped from a pump and is discharged outside the cropping ditch, so that the condition that the roots of plants are rotted due to the fact that the water in the cropping soil layer is excessive is avoided; and when the rainfall is less, the water in the water-collecting wells is slowly permeated into the cropping soil layer, so that water required by growth of the plants is supplemented.

Description

technical field [0001] The invention relates to a plant planting system, in particular to a plant planting system suitable for plant growth in saline-alkali soil. Background technique [0002] Saline-alkali land refers to the land where the soil contains excessive soluble salts. The reason for land salinization is that the soil and groundwater contain too much salt. Under the action of strong surface evaporation, the shallow underground water is transported to the surface through capillary tubes and evaporated. In the process of transporting water to the surface, the salt in the water is also brought to the surface. After the water is evaporated, the soil salt rises through capillary action and accumulates on the soil surface, and the salt remains on the surface and the shallow soil on the ground. Soil salinization occurs when there is too much salt and there is not enough fresh water to dilute it and drain it away. The saline-alkali land with a salinity above 0.3% and belo...
