Greening plant growth device

Abstract

The embodiment of the invention provides a greening plant growth device. The device comprises a shell, a soil layer and an air insulation layer; the shell is provided with a cavity and a bottom face,and the soil layer is arranged in the cavity of the shell; the air insulation layer is arranged between the soil layer and the bottom face. The greening plant growth device in the embodiment is simplein structure and is used for plant cultivation of a salinization area, quick greening of the high salinization area can be achieved, and later management and maintenance are easily conducted.

Description

technical field [0001] The invention relates to greening of saline-alkali land, in particular to a greening and planting device for saline-alkali areas. Background technique [0002] At present, domestic saline-alkali land greening is mainly realized by improving soil and planting saline-alkali-tolerant plants. The main methods are: one is to drain and wash the salt, to remove excess water and salt in the soil, control the groundwater level, and adjust the water-salt dynamics of the soil and groundwater; Lay underground pipes under the soil to drain away the salt in the soil, and control the groundwater level below the critical depth, so as to achieve the purpose of desalination in saline-alkali land; the third is the method of combining film-mulching planting technology with drip irrigation and water-saving technology; the fourth is changing drainage to storage The method, the area is not drained externally, the drainage is controlled in the area, and the vertical distribu...
