Embodiment 1

[0051] Embodiment one: change the fragile ecological environment of the loess area and increase the physical and chemical method of arable land, and the method operation steps are as follows in turn:

[0052] ① Bulldoze and level the mounds, plateaus, beams, etc. that need to be improved;

[0053] ② Measure the compactness, permeability coefficient and water content of the loess before improvement;

[0054] ③Destroy the columnar joints 1 of the loess by dynamic tamping, and eliminate the fine channels for water to penetrate downward. The control system of the dynamic tamping machine makes the rammer move freely; the potential energy of the rammer is converted into kinetic energy, and its kinetic energy can damage the columnar joints 1 of the loess, thereby changing the structure of the loess. After dynamic compaction, the columnar joints are destroyed, and the structure of the loess is changed, so that water molecules can be conserved in the loess, increasing the humidity and...

Embodiment 2

[0058] Embodiment two: change the fragile ecological environment of the loess area and increase the physicochemical method of arable land, method operation step in turn

[0059] The steps are as follows:

[0060] ① Bulldoze and level the mounds, plateaus, beams, etc. that need to be improved;

[0061] ② Measure the compactness, permeability coefficient and water content of the loess before improvement;

[0062] ③Destroy the columnar joints 1 of the loess by dynamic tamping, and eliminate the fine channels for water to penetrate downward. The control system of the dynamic tamping machine makes the rammer move freely; the potential energy of the rammer is converted into kinetic energy, and its kinetic energy can damage the columnar joints of the loess, thereby changing the structure of the loess. After the dynamic tamping, the columnar joints are destroyed, and the loess The structure of the soil changes, so that water molecules can be retained in the loess, increasing the hum...

Embodiment 3

[0067] Embodiment three: change the fragile ecological environment in the loess area and increase the physicochemical method of arable land, and the method operation steps are as follows in turn:

[0068] ① Bulldoze and level the mounds, plateaus, beams, etc. that need to be improved;

[0069] ② Measure the compactness, permeability coefficient and water content of the loess before improvement;

[0070] ③Destroy the columnar joints 1 of the loess by dynamic tamping, and eliminate the fine channels for water to penetrate downward. The control system of the dynamic tamping machine makes the rammer move freely; the potential energy of the rammer is converted into kinetic energy, and its kinetic energy can damage the columnar joints 1 of the loess, thereby changing the structure of the loess; the columnar joints 1 are destroyed after dynamic tamping , the structure of the loess has changed, so that water molecules can be conserved in the loess, increasing the humidity and water c...

Abstract

The invention discloses a physical chemistry method for changing a fragile ecological environment in a loess area and increasing arable land. The method includes the steps of 1, conducting bulldozing leveling on loess hills, table land and ridges which need to be improved; 2, measuring the compactness, permeability coefficient and moisture content of loess before improvement; 3, destructing columnar jointing of the loess through dynamic compaction of a dynamic compaction machine, and eliminating subtle channels which make water permeate downward and are produced by columnar jointing; 4, sprinkling a grouting material on the loess after the dynamic compaction, wherein the grouting material permeates along the vertical columnar jointing of the loess, and the grouting material expands and solidifies rapidly when permeating into a predetermined position under the earth surface and thus blocks the vertical columnar jointing; 5, detecting the permeability, compaction degree and moisture content of the improved loess, and determining plants which can be planted. The physical chemistry method has the advantages of effectively preventing soil and water loss in the loess area, changing the soil microstructure, making the water conserved in the soil structure, and effectively improving the fragile ecological environment in the loess area.

Description

technical field [0001] The invention relates to a method for changing the ecological environment and arable land in the loess area. Background technique [0002] In northern China, the Loess Plateau starts from the Taihang Mountains in the east, extends to the Wushao Mountains in the west, connects to the Qinling Mountains in the south, and reaches the Great Wall in the north. It mainly includes Shanxi, Shaanxi, and parts of Gansu, Qinghai, Ningxia, Henan and other provinces. The world's largest loess accumulation area. The loess is 50-180 meters thick, the climate is relatively dry, the precipitation is concentrated, the vegetation is sparse, and the soil erosion is serious. [0003] The three major landform types of mountain, plain and Sichuan are the main body of the Loess Plateau. The original (or plateau) refers to the flat ground of the Loess Plateau. The plateau is wide and suitable for mechanized farming. It is an important agricultural area. However, the plateau ...
