Abstract

The invention relates to a soybean water lactic acid bacteria soil restoration agent and a preparation method thereof. In the present invention, it is made by fermenting the fermented liquid of Carex, mugwort, Artemisia pilosa, red amaranth, bracken and soybean water lactic acid bacteria, which can improve the ability of the restoration agent to enrich heavy metals, and at the same time improve the ability to degrade pollutants. Increase the content of soil microorganisms, while repairing the soil, also increase the self-purification ability of the soil; the main raw material of the soil repair agent prepared by the present invention is the fermented liquid of lactic acid bacteria in soybean water, and the fermented liquid of lactic acid bacteria in soybean water utilizes the remaining soybean water in the production of soybean products as The main raw material is fermented, which can not only effectively utilize soybean water and save the cost of processing soybean water, but also reduce the cost of soil remediation agent, which is beneficial to the remediation of soil pollution and is easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of soil remediation, and in particular relates to a soil remediation agent for lactic acid bacteria of soybean water and a preparation method thereof. Background technique [0002] my country has a large population, and the per capita arable land area is relatively small. The growth and development of crops will consume a large amount of nutrients in the soil, and with the harvesting of crop fruits, etc., the nutrient content in the soil available for crops to absorb and utilize becomes less and less, soil fertility and productivity decrease. In order to ensure the yield of crops, the input of nitrogen, phosphorus and potassium chemical fertilizers has been increasing continuously, and has the effect of increasing production within a certain period of time. However, with the increase of the service life of chemical fertilizers, the soil shows compaction, porosity decreases, organic matter content decreases, ...
