Problems solved by technology

At present, the soil desertification in our country is becoming more and more serious. If it is not improved in time, it will lead to rapid deterioration of the environment. However, the main means to improve desertification is to plant trees and grass. However, it is difficult to grow trees and grass due to soil desertification. Desertification, the first thing to do is to improve the soil

Embodiment 1

[0022] Step (1) plowing the desertified soil, the plowing depth is 30cm, and the plowed soil is put aside earlier to form an earth pit;

[0023] Step (2) Laying a layer of straw layer in the pit, the thickness of the straw layer is 3cm, spraying water on the straw layer until the straw layer is completely soaked; evenly sprinkle the microbial agent on the straw layer , the microbial agent includes one or more of Bacillus subtilis, lactic acid bacteria and yeast; the microbial agent includes Bacillus subtilis, lactic acid bacteria and yeast, and the mass ratio of Bacillus subtilis, lactic acid bacteria and yeast is 2:2:5;

[0024] The straw layer acts as a cushion layer to provide a basic fermentation space and environment for microbial agents, and as the microbial fermentation progresses, the straw layer will gradually ferment and rot, thereby increasing the nutrient content in the soil. The straw layer can also play a role in water retention and improve the structure of the ...

Embodiment 2

[0030] Step (1) plowing the sandy soil, the plowing depth is 40cm, the plowed soil is put aside earlier to form an earth pit;

[0031] Step (2) Laying a layer of straw layer in the pit, the thickness of the straw layer is 7cm, spraying water on the straw layer until the straw layer is completely soaked; evenly sprinkle the microbial agent on the straw layer , the microbial agent includes one or more of Bacillus subtilis, lactic acid bacteria and yeast;

[0032] Step (3) laying fermented layer on described microbial bacterial agent, the thickness of described fermented layer is 2cm, described fermented layer comprises bean dregs, distiller's grains and water mix, and the mass ratio of described bean dregs, described distiller's grains and water is 1:1:15, the mass ratio of the fermented layer to the microbial inoculant is 25:1;

[0033] Step (4) laying a leaf layer on the fermentation layer, the thickness of the leaf layer is 3cm, and spraying water to the leaf layer until all...

Embodiment 3

[0036] Step (1) plowing the sandy soil, the plowing depth is 33cm, the plowed soil is put aside earlier to form an earth pit;

[0037] Step (2) Laying a layer of straw layer in the pit, the thickness of the straw layer is 3cm, spraying water on the straw layer until the straw layer is completely soaked; evenly sprinkle the microbial agent on the straw layer , the microbial agent includes one or more of Bacillus subtilis, lactic acid bacteria and yeast;

[0038] Step (3) laying fermented layer on described microbial bacterial agent, the thickness of described fermented layer is 1cm, and described fermented layer comprises bean dregs, distiller's grains and water mixing, and the mass ratio of described bean dregs, described distiller's grains and water is 1:1:10, the mass ratio of the fermented layer to the microbial inoculant is 20:1;

[0039] Step (4) laying a leaf layer on the fermentation layer, the thickness of the leaf layer is 2cm, and then spraying water to the leaf lay...

Abstract

The invention discloses a method for modifying desertified soil. The method comprises the steps of step (1) desertified soil is turned over, the turning depth is 30-40 cm, the turned soil is placed aside, and a pit is formed; step (2) a straw layer is laid in the pit; the straw layer is sprayed with a microbial agent uniformly, and the microbial agent comprises one or more of bacillus subtilis, lactic acid bacteria and saccharomycetes; step (3) a fermentation layer is laid on the microbial agent and comprises bean dregs, distilled grain and water, and the mass ratio of the fermentation layer and the microbial agent is (20-25):1; step (4) a leaf layer is laid on the fermentation layer; step (5) the straw is cut into straw granules, the straw granules are stirred into the turned soil, and the leaf layer is covered with the soil stirred with the straw granules. According to the method for modifying the desertified soil, the soil environment is improved, the soil structure is modified, andfinally the soil desertification condition is improved.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method for improving sandy soil. Background technique [0002] Soil desertification generally refers to the process of turning good soil or usable land into sandy soil or land or even desert. The main processes of soil desertification are wind erosion and wind accumulation. In the surrounding areas of the desert, due to vegetation destruction or grassland overgrazing or reclamation into farmland, the soil becomes dry due to dehydration, soil particles are scattered, eroded by wind, and the content of fine particles decreases. After the wind has passed or weakened, the wind-blown sand particles gradually accumulate on the soil surface to make the soil sandy. Therefore, soil desertification includes the process of wind erosion of grassland soil and the process of wind-sand accumulation in remote areas. At present, the soil desertification in our country is becoming more and more ser...
