Microbial manure of containing rare earth elements

Abstract

This invention discloses a microbial fertilizer containing rare earth elements. The microbial fertilizer is composed of active major strains, chitosan-type carrier, modified protective agent, neutralizer and rare earth element promoter. The major strains include Azotobacter, P / K-leaching bacteria (or silicate bacteria), and cellulose decomposing fungi. The chitosan-type carrier is suitable for both liquid and solid / freeze-dried microbial fertilizers, and can increase the survival rate of the major strains. The rare earth element promoter is chloride or nitrate of rare earth elements, and can increase the survival rate and fertilizing effect. Chitosan can rapidly degrade in natural soil conditions, thus bringing no pollution to soil.

Description

technical field

[0001] The present invention relates to a microbial fertilizer that uses microorganisms to produce fertilizer from the soil environment, in particular to a microbial fertilizer that uses nitrogen-fixing bacteria, potassium-dissolving bacteria, phosphorus-dissolving (dissolving) bacteria, and cellulolytic bacteria to produce fertilizer effects from the soil environment . Background technique

[0002] The chemical fertilizer itself has certain defects and the unreasonable use of chemical fertilizers has polluted the environment and wasted chemical fertilizers, so "green fertilizers" - microbial fertilizers - came into being. Although microbial fertilizers are referred to as bacterial fertilizers, although they cannot completely replace chemical fertilizers, they can greatly save chemical fertilizers and improve soil structure. Microbial fertilizers refer to a class of preparations containing live microorganisms that produce specific fertilizing effects. At pr...
