Problems solved by technology

[0002] In recent years, with the rapid growth of my country's population, the area of ​​arable land has been decreasing day by day, excessive reclamation and unreasonable human use have accelerated the process of land degradation, resulting in partial or complete loss of land productivity, which has greatly affected the sustainability of agriculture and forestry. develop
In order to solve this situation, microbial fertilizers for improving and repairing soil have appeared on the market one after another, but the existing microbial fertilizers for improving and repairing soil are improving land structure, enhancing soil water retention and aeration, and improving soil Fertility is less effective

Embodiment 1

[0017] A microbial fertilizer for soil improvement and repair, which is prepared from the following raw materials in parts by weight: 65-75 parts of biochar, 10-14 parts of potassium chloride, 4-6 parts of polypropylene peptide amine, and 6-6 parts of compound microbial bacterial agent 10 parts, lignin iron 0.5-1.5 parts, attapulgite 3-5 parts. Wherein, the biochar is straw or sawdust; the composite microbial agent includes actinomycetes, nitrogen-fixing bacteria, phosphorus-solubilizing bacteria and potassium-solubilizing bacteria, and the effective number of viable bacteria is >200 million / g; the actinomycetes, nitrogen-fixing bacteria The weight ratio of bacteria, phosphorus solubilizing bacteria and potassium solubilizing bacteria is (1.4-1.8): (0.6-0.8): (0.9-1.1): (1.2-1.4).

[0018] The preparation method of the microbial fertilizer for above-mentioned soil improvement and restoration, the specific preparation steps are as follows:

[0019] (1) Grinding the biochar in ...

Embodiment 2

[0023] A microbial fertilizer for soil improvement and restoration, prepared from the following raw materials in parts by weight: 70 parts of biochar, 12 parts of potassium chloride, 5 parts of polypropylene peptide amine, 8 parts of compound microbial bacterial agent, and 1 part of lignin iron , 4 parts of attapulgite. Wherein, the biochar is straw or sawdust; the composite microbial agent includes actinomycetes, nitrogen-fixing bacteria, phosphorus-solubilizing bacteria and potassium-solubilizing bacteria, and the effective number of viable bacteria is >200 million / g; the actinomycetes, nitrogen-fixing bacteria The weight ratio of bacteria, phosphorus solubilizing bacteria and potassium solubilizing bacteria is 1.6:0.7:1:1.1.

[0024] The preparation method of the microbial fertilizer for above-mentioned soil improvement and restoration, the specific preparation steps are as follows:

[0025] (1) Grinding the biochar in the above parts by weight to 250 mesh;

[0026] (2) M...

Abstract

The invention provides microbial fertilizer for soil improvement and remediation, which is prepared from the following raw materials in parts by weight: 65 to 75 parts of charcoal, 10 to 14 parts of potassium chloride, 4 to 6 parts of polypropylene peptide amine, 6 to 10 parts of compound microbial agent, 0.5 to 1.5 parts of lignin iron, and 3 to 5 parts of attapulgite. According to the microbialfertilizer for soil improvement and remediation, which is provided by the invention, the charcoal is used as the main raw material and is matched with a certain amounts of potassium chloride, polypropylene peptide amine and compound microbial agent, so that rich organic matter and elements of nitrogen, phosphorus and potassium can be provided for soil, soil hardening and aggregating phenomena areeffectively improved, and air permeability and the water-retaining property of the soil are enhanced; by the lignin iron and the attapulgite, an iron shortage phenomenon of the soil is improved and deleteriousness of the soil is reduced, so that comprehensive performance of the soil is greatly improved, fertility of the soil is improved, and yield of crops is reinforced.

Description

technical field [0001] The invention relates to the technical field of microbial fertilizers, in particular to a microbial fertilizer for soil improvement and restoration and a preparation method thereof. Background technique [0002] In recent years, with the rapid growth of my country's population, the area of ​​cultivated land has been decreasing day by day. Over-reclamation and irrational human use have accelerated the process of land degradation, resulting in partial or complete loss of land productivity, which has greatly affected the sustainability of agriculture and forestry. develop. In order to solve this situation, microbial fertilizers for improving and repairing soil have appeared on the market one after another, but the existing microbial fertilizers for improving and repairing soil are improving land structure, enhancing soil water retention and aeration, and improving soil Fertility is less effective. Contents of the invention [0003] The purpose of the p...
