Embodiment 1

[0039] 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 2 As shown, the inside of the planting ditch 6 is filled with a 1cm thick breathable anti-seepage layer 1, a 10cm thick leveling layer 3, an 8cm ...

Embodiment 2

[0043] like image 3 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 and the breathable anti-seepage layer 1 are all parallel to the horizontal plane, The leveling layer 3 is laid in a gradually decreasing manner along its width direction, so that the surface where the leveling layer 3 is in contact with the protection layer 4 is inclined, and the protection layer 5 is laid along the surface (the leveling layer 4). Layer 3 is laid parallel to the surface in contact with the protection layer 4, so that the planting soil layer 5 has an inclined bottom surface.

Embodiment 3

[0045] like Figure 4 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 leveling layer 3 and the protective 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 horizontal part. A water well 9 is located above the level of said protective layer 4 .

Abstract

The invention discloses a saline-alkali soil plant planting system, which comprises a planting groove formed in saline-alkali soil, wherein a breathable anti-seepage layer and a planting soil layer are filled into the planting groove from top to bottom; the side wall of the planting groove is a water-proof side wall; a plurality of water collecting wells are arranged in the planting groove at certain intervals along a length direction; the water collecting wells are provided with water-permeable well walls made of a water-permeable material; the bottoms of the water collecting wells are positioned in the planting oil layer. In the saline-alkali soil plant planting system, the water-collecting wells are provided with the water-permeable well walls made of the water-permeable material, and the bottoms of the water collecting wells are positioned in the planting oil layer. In rainy seasons, water in the water collecting wells is pumped out by using pumps and drained out of the planting groove, so that water accumulated in the planting groove is reduced, and roots of plants are prevented from being rotten by excessive water in the planting soil layer; moreover, the drained water can be used for irrigating other plants; in non-rainy seasons, water in the water collecting wells permeates into the planting soil layer slowly so as to replenish water needed by plant growing.

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...
