Problems solved by technology

[0008] These two technologies can quickly improve soil conditions to a certain extent, but as time goes by, after the formation of soil capillaries, the saline water in the ground will still be guided to the ground, resulting in secondary salinization of the soil, which cannot last for a long time. Maintain soil pH, which seriously affects plant growth
In addition, because the surface soil must be transformed and turned, it will often consume a lot of manpower, material resources and financial resources.
At the same time, the existing technology can only achieve the purpose of alleviating soil salinity and alkalinity by isolating salinity and alkali, and cannot effectively improve the physical and chemical environment of the soil for a long time. Therefore, such projects and technologies cannot improve the ecological environment of forest land soil

Embodiment 1

[0031] The present invention is a kind of method that is applicable to saline-alkali soil urban landscaping organic surface covering, is characterized in that, the method step is as follows:

[0032] Step 1: In the area where the soil salinity condition needs to be improved, define this area as an organic surface coverage area, loosen the soil at a depth of 50 cm in the soil within the projection range of the tree crown around the trees in this area, and cut off the capillary in the soil;

[0033] Step 2: Lay plastic grids on the soil surface, and then cover with an organic covering layer of 30 mm to reduce the evaporation of surface water, so that the capillary in the original underground soil layer cannot conduct underground saline water to the surface soil, thereby avoiding the subsurface soil. Raw salinization, alleviate soil salinity;

[0034] Step 3: Sprinkle water: Sprinkle water and disinfectant on the surface of the covering material until the covering is soaked to ma...

Abstract

The invention belongs to the technical field of saline-alkali soil urban garden greenbelt construction, and relates to an organic ground surface covering method suitable for a saline-alkali soil urban garden greenbelt. The method comprises the following steps that firstly, in an area with the soil saline-alkali condition to be improved, the area is defined as an organic ground surface covering area, soil in the periphery crown projection range of trees in the area is loosed by the depth of 50 cm, and capillaries in the soil are cut off; secondly, plastic gratings are laid on the surface of the soil, then an organic covering layer is then additionally arranged by 30-50 mm to reduce ground surface moisture evaporation, and the capillaries in the underground raw soil layer cannot conduct underground salt-containing moisture to the soil in the ground surface layer, so that secondary salinization of the ground surface soil is avoided, and saline-alkali of the soil are relieved; thirdly, water is sprinkled, wherein water and disinfectant are sprinkled to the surface of the covering materials until the covering materials are completely wet, and the covering materials are settled and stabilized. By means of the organic ground surface covering method suitable for the saline-alkali soil urban garden greenbelt, the soil saline-alkali condition can be effectively improved, the soil ecological environment quality can be improved, survival and healthy growth of plants can be promoted, and management cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of construction of saline-alkali urban gardens and green spaces, and in particular relates to a method suitable for organic surface covering of saline-alkali urban gardens and green spaces. Background technique [0002] The salinity and alkalinity in saline-alkali urban gardens and green spaces limit the survival and healthy growth of plants. Generally, the salinity of urban soil in saline-alkaline land is above 0.5%. The cost of greening has doubled. In order to create a soil environment suitable for plant growth, large material and financial resources have been invested in urban construction, and there is no guarantee that the created soil environment can be maintained for a long time. [0003] The main reason for this situation is: the soil groundwater contains high salinity and alkali, which rises to the soil surface with the soil capillary, affecting the water environment for the normal growth of plant...
