Abstract

The invention relates to a soybean water lactobacillus soil remediation agent and a preparation method thereof. The soil remediation agent is prepared by fermenting carex tarumensis, artemisia argyi,artemisia sacrorum, amaranthus tricolor, pteridium aquilinum, and fermentation broth of soybean water lactobacillus. The heavy metal enriching performance and pollutant degrading performance of the soil remediation agent are enhanced. At the same time, the microbe content of soil is increased, the soil is remedied, and the self-cleaning performance of the soil is improved. The main raw material ofthe soil remediation agent is soybean water lactobacillus, which is prepared from soybean water that is the residue of soybean products. The soybean water is effectively utilized, the cost for processing soybean water and the cost of the soil remediation agent are reduced, and the soil remediation agent can be used to remedy soil and is convenient to popularize.

Description

Technical field [0001] The invention belongs to the technical field of soil remediation, and specifically relates to a soybean water lactic acid bacteria soil remediation agent and a preparation method thereof. Background technique [0002] Our country has a large population and a small area of ​​arable land per capita. The growth and development of crops will consume a large amount of nutrients in the soil, and with the harvest of crop fruits, the content of nutrients in the soil that can be absorbed and utilized by the crops decreases, soil fertility decreases, and productivity decreases. In order to ensure the yield of crops, the input of nitrogen, phosphorus and potassium fertilizers has been increasing continuously, and it will increase the output within a certain period of time. However, with the increase of the use of fertilizers, the soil shows compaction, reduced porosity, reduced organic matter content, and soil nutrients. Degradation phenomena such as uneven content a...
