Embodiment 1

[0037] A tobacco soil remediation agent, comprising 15 parts of biomass charcoal, 25 parts of sodium humate, 15 parts of trimercaptotriazine trisodium salt, 20 parts of general calcium, 15 parts of zinc sulfate, 20 parts of urea, and 15 parts of potassium dihydrogen phosphate , 5 parts of sodium silicate, 15 parts of proline.

[0038] Preparation method, concrete steps are as follows:

[0039] 1) Grind tobacco waste (such as tobacco stems, tobacco waste, unsuitable tobacco leaves, etc.) The final material is added to the pyrolysis reactor, and the carbonization reaction is carried out at 550°C for 10 minutes under anaerobic conditions to obtain biochar with a loose structure;

[0040] 2) Sodium humate, urea, and trimercaptotriazine trisodium salt are dissolved in water at room temperature and mixed evenly. The total amount of sodium humate, urea, and trimercaptotriazine trisodium salt to water is 1:4, to obtain a mixed solution;

[0041] 3) Pulverize common calcium, zinc su...

Abstract

The invention particularly relates to a remediation agent for tobacco soil. The remediation agent is prepared from biomass charcoal, sodium humate, trioctylthio-triazine trisodium salt, superphosphate, zinc sulfate, urea, monopotassium phosphate, sodium silicate and proline. According to the remediation agent for the tobacco soil, provided by the invention, treatment of improving heavy metals in the tobacco soil is realized by immobilized passivation of the heavy metals in the tobacco soil; a tobacco soil environment is remediated by remediating soil and improving soil fertility, and other chemical contamination to the soil caused by the remediation agent for the tobacco soil is effectively avoided.

Description

technical field [0001] The invention belongs to the field of soil improvement, and in particular relates to a tobacco soil restoration agent. Background technique [0002] With the acceleration of industrialization and urbanization in my country, soil heavy metals have become one of the largest and most harmful sources of environmental pollution. It is estimated that nearly 20 million hectares of arable land in China (accounting for about one-fifth of the total arable land area) are polluted by heavy metals, resulting in an annual economic loss of more than 20 billion yuan. Heavy metals enter the soil environment through different channels. Most of the heavy metals in the soil remain in the soil in various forms through complex physical and chemical reactions. At the same time, heavy metals accumulate in the edible parts of crops and enter the food chain cycle, thus posing a threat to human health. . In addition, because the vast majority of heavy metals do not undergo mic...
