Abstract

The invention discloses a low-temperature silicic acid soil conditioner and a preparation method thereof. The method comprises steps of taking raw materials, uniformly mixing the raw materials and grinding into powder to obtain pulvis. The raw materials comprise (by weight): silicate mineral substance powder with 95% and above of silica; and a powder mixture of high-purity silica sand, silica, plagioclase, zeolite, silicate tremolitum, alkali metal and potassium phosphate. The invention provides a soil conditioner for preventing plants from absorbing heavy metal and removing heavy metal and apreparation method thereof. Through the soil conditioner prepared by the method, plants can be prevented from absorbing heavy metal and total heavy metal in soil can be removed, and unnecessary wasteof silicon mineral matter and water glass produced in various regions can be reduced. Humic substances are mixed for use, and various resources are effectively used. Thus, regional environment pollution is reduced, and high-quality products are produced and supplied at low cost for farmers in regions where fertilizers and the soil conditioner are required.

Description

technical field [0001] The invention relates to the technical field of soil improvement preparations, in particular to a low-temperature silicic acid soil improvement agent for preventing plants from inhaling heavy metals and removing heavy metals and a preparation method thereof. Background technique [0002] Heavy metal pollution of the soil refers to human activities, the content of trace metal elements in the soil exceeds the background value, and the excessive content caused by excessive deposition is collectively referred to as soil heavy metal pollution. Heavy metals refer to metals with a specific gravity equal to or greater than 5.0, such as Fe, Mn, Zn, Cd, Hg, Ni, Co, etc.; As is a metalloid, but due to its chemical properties and environmental behavior are similar to heavy metals, Therefore, when discussing heavy metals, arsenic is often included, and some directly include it in the scope of heavy metals. Due to the high content of iron and manganese in soil, it ...
