Soil improvement method for tillage-free three-dimensional material embedding

Abstract

The invention discloses a soil improvement method for tillage-free three-dimensional material embedding. The method includes the following steps that under the condition that a soil tillage layer is not turned over, high-pressure airflow is injected to soil needing to be modified to perform spray explosion so that the soil can be deep loosened and a soil water partition layer can be broken; while the high-pressure airflow is injected, soil modifying materials can be conveyed into the soil within the spray explosion range; while the degraded soil problems about soil erosion, desertification, gleying and like are solved, deep placement is performed on the soil by injecting the high-pressure airflow for jetting and spray explosion under the condition the soil is not turned over, soil porosity is increased, the air injection amount is increased, the volume weight of degraded soil is lowered, the soil can be loose and breathable, rainwater penetration speed and rainwater penetration amount are enhanced, the water-holding capacity of the soil is improved, soil moisture preservation is facilitated, erosion is reduced, more rainwater can be absorbed, generation of a runoff can be delayed, the strength of the runoff is weakened, scouring of the surface runoff on the soil is relieved, and water and soil loss is reduced.

Description

technical field [0001] The invention relates to the field of modern agricultural soil improvement, in particular to a soil improvement method for no-tillage three-dimensionally implanted materials. Background technique [0002] Soil is the loose surface layer on the earth's land surface that can produce plant harvests. It is a part of the natural environment in which human society lives and is an important source of energy and certain nutrients for animals and humans to maintain their life activities. With the intensification of the contradiction between population-resource-environment, the degradation of the quality of soil and land resources that human beings rely on for survival and development is becoming more and more serious. As far as my country is concerned, soil degradation is serious. The total area of ​​soil degradation caused by soil erosion, desertification, salinization, gleization, acidification, soil fertility decline and soil pollution accounts for 40% of th...
