Abstract

The invention relates to an ecological reagent for solving excessive heavy metal and a preparation method thereof. The reagent is prepared from humic acid, saccharomycetes, bacillus subtilis, bacillus licheniformis, carbon nanotubes, nano-zinc, nano-iron, ammonium metaphosphate, disodium EDTA (Ethylene Diamine Tetraacetic Acid), water and the like. The reagent is green and environment-friendly, and can be directly irrigated or sprayed on crops or soil during use, so that the content of heavy metals in products such as medicinal materials and vegetables can be reduced, the heavy metals are prevented from exceeding the standard, the growth of the medicinal materials and the vegetables can be promoted, the quality of the medicinal materials can be improved, and meanwhile, diseases and insect pests can be reduced. The preparation process of the reagent is simple, the whole preparation process is green and environment-friendly, and no three wastes are discharged.

Description

technical field [0001] The invention relates to an ecological reagent for solving the problem of excessive heavy metals and a preparation method thereof. It can be used in fields such as planting of vegetables and medicinal materials and soil improvement. Background technique [0002] In recent years, with the development of industry and the extensive use of agricultural inputs, the world is facing more and more serious soil environmental safety issues, among which heavy metal pollution has received the most attention. After planting crops in soil with high heavy metal content, the crops will absorb a large amount of heavy metals, causing the heavy metal content of crop products to exceed the standard, which will cause great harm to the human body after human consumption. There are three main ways to control soil heavy metal pollution. One is to change the existing state of heavy metals in the soil so that it changes from an active state to a stable state; the other is to r...
