Problems solved by technology

The main reason for soil salinization is that the soil contains potassium, sodium, calcium, magnesium chloride, sulfate, bicarbonate and other saline-alkali components, which change the physical and chemical properties of the soil, resulting in the reduction of soil quality and the growth of plants. It has been restrained to a certain extent, resulting in reduced land production, decreased farmers' income, large areas of soil resources cannot be fully utilized, and land utilization rates have declined.
Since it is difficult for most plants to be exposed on the surface of the alkaline land, the salinity of the surface soil will further increase in the season of strong evaporation, causing a vicious cycle of saline-alkali land and destroying the ecosystem

Abstract

The invention discloses an urban greening saline and alkaline land regulating method which comprises the following steps that a strip-shaped accommodation groove of a compression moulding shell is filled with nutrient soil which is mixed with drought resisting grass seeds; a cover body which is compressed into a sheet shape is buckled in the opening position of the strip-shaped accommodation groove filled with the nutrient soil to prepare and obtain carrying bodies I with the cross sections in approximate triangles; a plurality of carrying bodies I incline at certain angles and are arranged sequentially into carrying bodies II in an end-to-end connection manner; a plurality of carrying bodies II are arranged at intervals uniformly on an exposed layer of to-be-improved soil; the spaces among the plurality of carrying bodies II are filled with soil conditioners; the plurality of carrying bodies II are covered with thickness soil conditioners; 1.5-2.5 L / m<2> water is sprayed to the soil conditioners by one time at the interval of 20-30 d. According to the urban greening saline and alkaline land regulating method, the saline and alkaline land structure can be modified in short time, and the moisture and fertility preservation effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to an urban greening saline-alkali land conditioning method. Background technique [0002] One of the types of soil degradation is soil salinization, which has threatened the survival and development of human beings. The main reason for soil salinization is that the soil contains potassium, sodium, calcium, magnesium chloride, sulfate, bicarbonate and other saline-alkali components, which change the physical and chemical properties of the soil, resulting in the reduction of soil quality and the growth of plants. It has been restrained to a certain degree, resulting in a reduction in land production, a decline in farmers' income, a large area of ​​soil resources cannot be fully utilized, and land utilization rates have declined. Since it is difficult for most plants to be exposed on the surface of the alkaline land, the salinity of the surface soil will further increase in ...
