Embodiment 1

[0041] Such as figure 1 As shown, the saline-alkali plant planting system of the present invention includes six planting ditches 6 arranged in parallel in the saline-alkali soil with an interval of 1 m. The sidewalls 7 of the planting ditches 6 are waterproof sidewalls, and the waterproof sidewalls are well dug. After the planting ditch 6 is formed by attaching a plastic sheet to its side wall, to prevent the saline-alkali water outside the planting ditch 6 from infiltrating into the planting ditch 6 from the side wall 7 thereof. Three water collection wells 9 are arranged in the planting trench 6 at intervals along its length. The well wall of the water collection well 9 is made of permeable material, and the bottom of the water collection well 9 is located in the planting soil layer 5. Inside; figure 2 It is a schematic cross-sectional view of a planting trench perpendicular to its length direction according to the present invention, such as figure 2 As shown, the inside of ...

Embodiment 2

[0046] Such as 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 is that the bottom surface of the planting ditch 6, the air permeable impermeable layer 1, and the protective layer 2 are parallel to the horizontal plane, and the leveling layer 3 is laid along its width direction in a gradually decreasing thickness, so that the surface of the leveling layer 3 in contact with the protective layer 4 is arranged obliquely, and the protective layer 5 is 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] Such as 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 impermeable layer 1 The protective layer 2, the leveling layer 3, and the protective layer 4 extend parallel to the horizontal plane along the width direction of the planting ditch to a side wall of the planting ditch at the low end of each layer, thereby dividing each layer into inclined parts and The horizontal part, the water collection well 9 is located above the horizontal part of the protective 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 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 are too salty. Under the strong surface evaporation, the shallow underground water is transported to the surface by capillary and is evaporated. In the process of delivering water to the surface, the salt in the water is also brought to the surface. After the water evaporates, the soil salt rises through capillary action and accumulates on the surface of the soil. The salt remains on the surface and the shallow soil of the ground. There is too much salinity, and there is not enough fresh water to dilute and drain it away, resulting in soil salinization. The saline-alkali land with a salinity above 0.3% and below 0.8% is either idle or barely use...
