Plant planting system for saline-alkaline soil

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 [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...

Problems solved by technology

[0005] In order to solve the problem in the prior art that the air-permeable anti-seepage aggregate layer is easily damaged by plant roots and cause underground saline-alkali water to run upwards, a plant planting system suitable for long-term growth of plants in saline-alkali land is provided.
