Problems solved by technology

Soil acidification has the following effects on crop production: first, it destroys the soil structure, causes compaction, reduces soil permeability and microbial activity, and makes the soil poor; second, it leads to an increase in the content of aluminum ions in the soil, causing crops to The yield is reduced, the quality is reduced, and even lead to death due to aluminum poisoning; the third is to increase the activity of heavy metal ions in the soil, making it easier to be absorbed by crops, aggravating the harm of heavy metals, and then endangering human health
At present, the soil conditioners traditionally used to improve acidic soil are mainly lime and alkaline industrial waste. Although these substances can reduce soil acidity, excessive or uneven application will cause local calcification, damage soil microorganisms, and affect soil structure. And it cannot meet the needs of crops for medium and trace element fertilizers at the same time
In addition, some people use alkali

Abstract

The present invention discloses an acid soil polytropic conditioning improvement method. The method comprises the steps of: (1) performing plough of soil by employing a hydraumatic overturning ploughmachine, and performing natural ventilation for 3-5 days; (2) uniformly scattering decomposed manures on the ploughed soil, performing sun exposure for 2-3 days, and employing the hydraumatic overturning plough machine again to perform plough of soil; and (3) uniformly spraying a dilute soil conditioner on the soil ploughed again, and finally employing the hydraumatic overturning plough machine for plough, wherein the soil conditioner raw materials comprise ore, microbial flora, polyacrylamide, phenolic resin, polymethyl methacrylate, shuck powder, polyvinyl alcohol, polyvinyl acetate, ammonium sulfate, rice husk carbon, flue gas desulfurization gypsum, Chinese medicine residues, bagasse and maize straws; a mode for dual regulation through combination of biology and chemistry is employed to perform soil improvement to achieve various effects of PH value regulation of the obstacle soils, micro-ecology regulation, granular structure regulation, solidified nutrient element activity regulation and resorption passivation soil harmful metal elements.

Description

technical field [0001] The invention relates to the field of soil improvement, in particular to a method for conditioning and improving acidic soil with multiple effects. Background technique [0002] Acidic soil is soil with a pH less than 7. In recent years, with the unreasonable large-scale application of inorganic chemical fertilizers, the area of ​​acidified soil has increased year by year, and the degree of soil acidification has accelerated significantly. At the same time, due to the influence of continuous planting mode, climate and other factors, the area of ​​acidic soil in my country has reached 200 million hectares. . Soil acidification has the following effects on crop production: first, it destroys the soil structure, causes compaction, reduces soil permeability and microbial activity, and makes the soil poor; second, it leads to an increase in the content of aluminum ions in the soil, causing crops to The yield is reduced, the quality is reduced, and even lea...
