Gap forming type hardened soil treatment method

Abstract

The invention discloses a gap forming type hardened soil treatment method, and belongs to the technical field of soil remediation. Hardened soil is pre-softened, gap forming main balls are thrown intothe deep part of the soil in a ploughing manner, a magnetic field effect is applied above the soil to force the gap forming main balls to migrate to the surface from the deep part of the soil, a macroscopic gap forming phenomenon is formed, in addition, in the process of migrating the gap forming main balls to the soil surface, due to the structural characteristics, the gap forming main balls canbe partially inserted when encountering hardened soil blocks, gas is forced to expand through extrusion action to trigger release of gas making microspheres, and the gas making microspheres are dissolved and react to release a large amount of gas after making contact with residual moisture in the soil; and the soil blocks are loosened and disintegrated by using sharply increased gas in the soil blocks to form a microscopic gap forming effect, and meanwhile, the dissolved and residual gas making microspheres also migrate upwards under the action of a magnetic field to assist in improving the gap forming effect, so that the loosening and gap forming effect on the hardened soil can be greatly improved in a short time.

Description

technical field [0001] The invention relates to the technical field of soil remediation, and more specifically, relates to a gap-making compacted soil treatment method. Background technique [0002] Soil compaction refers to the phenomenon that the surface layer of the soil is poor in structure due to the lack of organic matter, and the structure is destroyed and the soil material is dispersed under the action of external factors such as irrigation or rainfall, and the soil surface is hardened by the cohesive force after drying. [0003] As countries around the world pay more and more attention to the sustainable development of agriculture, higher requirements are put forward for the sustainability of soil production capacity. Especially in my country with a large population, little arable land, and the severe situation of food security, how to ensure the sustainable development of soil is particularly important. Soil compaction is one of the important manifestations of soi...

Drought may limit plant growth and yield formation

[0004] At present, to solve the problem of soil compaction, the commonly used method is deep plowing, which means that when planting seeds, it is necessary to dig deep, plow the land, turn up the deep soil in the field, and cover the shallow soil, so that the seeds can be planted. Lying deep in the soil, there are more nutrients, but the effect of deep plowing is short-lived and the cost of energy and time is high. Although deep plowing slows down soil compaction, it also destroys the surface cover developed by no-tillage management for many years, and also increases soil quality. The risk of erosion and topsoil compaction, the newly emerging methods of soil amendments and soil crushing all have certain defects. It is too passive and needs to be applied multiple times for a long period of time
