Improved saline-alkali soil plant cultivating system

Abstract

The invention discloses a saline-alkali soil plant cultivating system which comprises a cultivating furrow arranged in saline-alkali soil and is characterized in that a breathable anti-seepage layer, a breathable anti-seepage protection layer, a reservoir layer, a breathable anti-seepage protection layer and a cultivating soil layer are filled in the cultivating furrow from bottom to top, and lateral walls of the cultivating furrow are waterproof lateral walls. The breathable anti-seepage protection layer can prevent root systems of plants in the cultivating oil layer from extending downwards and damaging the breathable anti-seepage layer and avoid anti-seepage effect failure caused by the fact that the breathable anti-seepage layer is damaged by the root systems of the plants. The breathable anti-seepage protection layers are used for preventing the breathable anti-seepage layer on the lower portion from being impacted and deformed by rainwater permeating from the upper layer during a large amount of rainfall or preventing the surface of the breathable anti-seepage layer from being damaged by other layers directly laid on the breathable anti-seepage layer. The reservoir layer is used for saving moisture and further achieves a leveling effect to make preparations for laying of the upper layer.

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 salt, and there is not enough fresh water to dilute and drain it away, which causes the salinization of the soil. The saline-alkali land with a salinity above 0.3% and below 0.8% is either idle or bar...
