Problems solved by technology

[0003] Currently, peat, vermiculite, perlite or synthetic raw materials are commonly used as solid carriers for microbial agents. However, due to the uncertainty of the specific composition of peat, the quality of peat produced from different origins and textures is quite different. some uncertain factors
Peat is a non-renewable resource, and a large amount of mining will also have a negative impact on the ecological environment; vermiculite, perlite or artificial synthetic materials also have disadvantages such as the production process requires a large amount of energy or the cost is too high

Abstract

The invention discloses a microbial agent carrier which is characterized by comprising the following raw materials in percentage by mass: 40%-55% of manioc waste, 35%-50% of rice bran, 7%-15% of soybean meal and 0.5%-2% of trehalose. The cassava residues are derived from cassava starch residues or cassava alcohol residues, and the water content of the cassava residues is 1t after the cassava residues are treated; 10% but not 0, the particle size lt; the thickness is 1.0 mm; the grain size of the rice bran is 01-0.5 mm, and the water content is 1t; 10% and not zero; the particle size of the soybean meal powder is 01-0.5 mm, and the water content is 1t; 10% and not zero; the microbial agent carrier substrate has the advantages that agricultural wastes are used as main raw materials, waste is turned into wealth, the raw materials are sufficient, cheap and easy to obtain, the preparation is simple, the raw material production process is environment-friendly, the use is convenient, and the like. The microbial agent carrier substrate has a good bacterium carrying effect, and can fully absorb moisture so as to adsorb bacterial liquid. The microbial agent carrier disclosed by the invention contains various nutritional ingredients required for maintaining microbial activity, so that the preservation of the microbial agent is more facilitated; the survival time of microorganisms in the microbial agent is long, and the bacterial count is basically kept stable within 6 months.

Description

technical field [0001] The invention relates to the technical field of microorganisms, in particular to a method for preparing a microbial agent carrier. Background technique [0002] Guangxi is the largest cassava-producing area in my country, with cassava planting area and output accounting for more than 60% of the country. Cassava residue is the solid waste produced from tapioca starch and cassava finesse, and its main components are carbohydrates, including starch, cellulose, hemicellulose, lignin and a small amount of protein. Cassava residue is one of the agricultural wastes obtained in large quantities during the production of cassava starch. It has a large output and high processing cost. Its large-scale dumping has caused many environmental problems. Cassava wastewater contains high concentrations of organic compounds, and improper disposal may lead to eutrophication of rivers; cassava The slag encroached on the farmland, the poisonous gas produced during the metam...
