Microbial sustained-release sphere for soil repairing

Abstract

The invention discloses a microbial sustained-release sphere for soil repairing, and belongs to the technical field of soil repairing. The microbial sustained-release sphere comprises a sustained-release sphere, wherein the sustained-release sphere comprises an inner water-soluble membrane, and the inside of the inner water-soluble membrane coats a plurality of microbial carrier spheres and microbial degradable plastic film spheres, which are distributed alternately; soil repairing microbial flora is adhered to the microbial carrier spheres; the microbial degradable plastic film spheres are filled with hydrogen peroxide; a plurality of straw fiber ropes which are uniformly distributed are fixedly connected on the inner wall of the inner water-soluble membrane, and are in a puffed shape; after being dosed into soil, the sustained-release spheres can be gradually degraded under the moisture effect along with time passing for constantly repairing the soil, the number of microbes can be constantly ensured, multiple dosage is not required, labor and materials can be saved, and the using method is diversified since the microbial sustained-release spheres can be dosed into soil optionallyin a turbid liquid manner.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a microbial slow-release ball for soil remediation. Background technique [0002] Soil microbial remediation technology is a remediation technology that uses indigenous microorganisms or artificially domesticated microorganisms with specific functions to reduce the activity of harmful pollutants in the soil or degrade them into harmless substances through their own metabolism under suitable environmental conditions. [0003] The Chinese invention patent with the publication number CN100417459C discloses a solid composite microbial microsphere for soil remediation and a preparation method thereof. In the method, calcium alginate is used as an embedding material, and solid calcium carbonate is used as a solid porogen. Degradable fungi, bacterial strains and nutrients, and a method for preparing solid composite microbial microspheres. It has the advantages of high mass tra...

Problems solved by technology

[0004] However, in the actual soil remediation process, there may be rainfall and other situations, which will directly affect the effect of soil remediation, resulting in the loss or dilution of microorganisms, which makes it difficult to achieve the expected remediation effect, and generally requires multiple injections to be effective. Only by ensuring the number of microorganisms can the effect of restoration be guaranteed. The above three published Chinese invention patents have not proposed a better solution, and when treating the soil where crops need to be planted, operations such as fertilization are required after microbial treatment.
