Example Embodiment
[0007] The embodiments of the present invention are described in detail below.
[0008] The present invention utilizes decomposed chicken manure, zeolite powder and brown coal powder, which have a wide source and low cost, as carriers, and combines Bacillus megaterium, Bacillus subtilis, silicate bacteria and bacteria that have the functions of dissolving phosphorus and potassium that have been popularized and applied. Voluntary nitrogen-fixing bacteria with nitrogen fixation are sprayed on the carrier, granulated by a disc granulator and low-temperature drying method is used to prepare the degraded soil remediation agent. The detailed process is as follows:
[0009] The decomposed and crushed chicken manure, zeolite powder and brown coal powder are mixed in a 2:1:1 ratio and used as a carrier. Bacillus megaterium, Bacillus subtilis, silicate bacteria and autogenous nitrogen-fixing bacteria with a bacterial content of more than 2 billion / g Mix 1:1:1:1 as a solvent. The solvent is ...
