Description
Technical Field
The invention relates to an ecotype reagent for solving heavy metal overproof and a preparation method thereof. Can be used in the fields of planting vegetables, medicinal materials and the like, soil improvement and the like.
Background
In recent years, with the development of industry and the use of agricultural input products in large quantities, the world faces more and more serious soil environment safety problems, and the heavy metal pollution is the most concerned. After the crops are planted in the soil with high heavy metal content, the crops can absorb a large amount of heavy metal, so that the heavy metal content of the crop products exceeds the standard, and people can be greatly injured after eating the crops. The method mainly comprises three approaches for treating the heavy metal pollution of the soil, namely changing the existing state of the heavy metal in the soil to convert the heavy metal from an activated state to a stable state; secondly, removing heavy metals from the soil; and thirdly, bioremediation, which is a process of reducing the concentration of heavy metals in soil or changing the form of heavy metals by using the metabolic activity of organisms so as to partially or completely restore the polluted soil environment to the original state. The repair measures mainly include phytoremediation and microbial remediation. Because of its advantages of good effect, low investment, low cost, easy management and operation, no secondary pollution, etc., it is increasingly paid attention to by people and becomes a hotspot for the research of contaminated soil remediation and engineering application. The three methods have advantages and disadvantages, and how to effectively repair the heavy metal contaminated soil becomes a hot point of domestic and foreign research. Patent publication No. CN104550218A discloses a method for adsorbing and transferring heavy metals in soil, mushroom and horsetail are planted on the same soil simultaneously for 2-3 growing seasons or continuously for two years, and 60% -70% of heavy metal element components in the soil can be absorbed. Patent publication No. CN111606769A discloses a soil conditioner for heavy metal pollution treatment of soil, which comprises oyster shell, straw, kitchen garbage, chicken and duck feces, cow dung, urea, potassium silicate, ferric oxide and actinomycetes. Although the preparation method has certain capability of removing heavy metals, the preparation process is not environment-friendly and pollutes the environment. The publication No. CN111659351A discloses a modified biochar for efficiently releasing silicon and adsorbing heavy metals and a preparation method thereof, and the used modified biochar is straw treated by a sodium citrate solution, and is subjected to crushing and pyrolysis treatment for 2-3 hours and cooling to obtain a modified biochar material. Although total metals can also be adsorbed, the process is complicated. The publication No. CN111662726A discloses a composite humic acid soil restoration agent, which is prepared by taking cotton stalks, straw stalks and vegetable branch stalks as raw materials, preparing straw fermented humic acid under a specific process, and adding weathered coal activated humic acid and carbon product residual auxiliary materials. The soil remediation agent can effectively inhibit the biological effectiveness of heavy metals Cu, Zn, Cr and Ni, but the preparation process is complex and time-consuming. Publication No. CN111606767A discloses a soil remediation agent and a preparation method thereof, wherein modified zeolite, organic matters (humic acid, furfural residues, mushroom residues and sugar residues), plant ash, nano-cellulose, a biological agent, trace elements and a granulation auxiliary agent are adopted as raw materials. The preparation method of the invention is complex, and comprises the process of heating the mixture at 550 ℃ for 2h after drying.
