Remediation agent for reducing disintegration of soil

Abstract

The invention discloses a remediation agent for reducing disintegration of soil. The remediation agent is made from the following raw materials, by weight part, 40-42 of fresh reed stalks, 1.3-1.4 of sodium benzoate, 14-15 of vinasse, 8-9 of pig bone meal, 19-21 of tea bran, 6-7 of dried powdery orange peels, 4-5 of ammonium dihydrogen phosphate, 2.3-2.5 of boric acid, 55-58 of polluted pig dung and urine, 15-17 of a black liquor from papermaking, 3.4-3.6 of a nitric acid solution with the concentration being 10%, 13-14 of a thick alum liquid and a proper amount of water. The remediation agent is available in raw materials and causes no bad effect on the environment. Through utilization of plant biochar and through addition of multiple organic raw materials, the structural coupling and strength among soil particles is greatly improved. The hardness and shearing strength of the soil is increased, the water retention capacity of the soil is improved, and the still water disintegration speed of soil is decreased. The remediation agent can be widely applied to agricultural and forestal planting, building operations, and so on, and the use value of the soil is increased.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a restoration agent for reducing soil disintegration. Background technique [0002] Soil improvement is aimed at the poor texture and structure of the soil, and corresponding measures are taken to improve soil properties and soil fertility. Soil improvement and restoration agent is an important application of soil improvement. However, the soil remediation and improvement agents currently on the market have many defects: one is that the raw materials used contain artificially synthesized polymer compounds, which are not easy to decompose in the soil and remain for a long time, which has potential safety hazards; Soils, such as acidic and alkaline soils, have no effective targets for heavy metal pollution and nutrient deficiencies, resulting in low efficiency of improvement and restoration, or even counterproductive effects; third, the long cycle and high cost of soil imp...

However, the soil remediation and improvement agents currently on the market have many defects: one is that the raw materials used contain artificially synthesized polymer compounds, which are not easy to decompose in the soil and remain for a long time, which has potential safety hazards; Soils, such as acidic and alkaline soils, have no effective targets for heavy metal pollution and lack of nutrients, resulting in low efficiency of improvement and restoration, or even counterproductive effects; third, the cycle of soil improvement is long and the cost is high, so it cannot be applied on a large scale

[0003] Soil disintegration refers to the characteristics of soil disintegration and disintegration because the structural connection and strength between soil particles are weakened or lost by the impact of water immersion when the soil is placed in still water. The soil with strong disintegration is fragile and not suitable for construction. Construction and agricultural and forestry production, the soil use value is low

[0004] As a renewable biological resource with a wide range of sources and low cost, pig manure has great potential as a raw material for soil improvement and restoration because it is rich in organic matter and nutrients such as nitrogen, phosphorus, and potassium. The feed contains a large amount of additives during the process, resulting in excessive heavy metals and indirectly polluting the excrement
