Embodiment 1

[0057]Embodiment 1, the preparation of inoculum carrier matrix

[0058] 1. Processing of raw materials: drying the tapioca starch residue in the sun, the moisture content is 8.4%, pulverizing the dried tapioca starch residue with a pulverizer, passing through a sieve with an aperture of 0.85 mm, and collecting the sieved tapioca starch residue;

[0059] The particle size of the sieved tapioca starch residue is less than 0.85mm, and the moisture content is 8.4%;

[0060] 2. Nutrient supplementation: add corn flour (also called corn flour) to the above-mentioned sieved product by 8% of the weight of the tapioca starch residue after sieving, and mix to obtain a mixed product;

[0061] 3. Drying: the moisture mass content of the above mixed product is dried to 8%, and the dried product is sterilized by steam at 110° C. for 60 minutes to obtain a bacterial agent carrier matrix.

Embodiment 2

[0062] Embodiment 2, the preparation of inoculum carrier matrix

[0063] 1. Raw material treatment: drying the cassava alcohol residue in the sun, the moisture content is controlled at 9%, pulverizing the dried cassava alcohol residue with a pulverizer, passing through a sieve with an aperture of 0.85 mm, and collecting the sieved cassava alcohol residue;

[0064] The particle size of the sieved cassava alcohol residue is less than 0.85mm, and the moisture content is 9%;

[0065] 2. Nutrient supplementation: adding corn flour and 2% soybean meal by weight of the cassava alcohol residue to the cassava alcohol residue after the sieving, and mixing to obtain a mixed product;

[0066] 3. Drying: the moisture mass content of the above mixed product is dried to 9%, and the dried product is sterilized by steam at 110° C. for 60 minutes to obtain a bacterial agent carrier matrix.

Embodiment 3

[0067] Embodiment 3, the preparation of inoculum carrier matrix

[0068] 1. Raw material treatment: The cassava starch residue and the cassava alcohol residue are dried in the sun respectively, and the moisture content is controlled at 9%. Sieved tapioca starch residue and sieved tapioca starch residue;

[0069] The particle size of the sieved cassava starch residue and the sieved cassava alcohol residue are both less than 0.85mm, and the moisture content is 9%;

[0070] 2. Nutrient supplementation: mix the sifted tapioca slag and the sifted tapioca slag in a mass ratio of 1:1 to obtain a mixed tapioca slag, add corn flour according to 10% of the weight of the mixed cassava slag, and mix to obtain a mixed product ;

[0071] 3. Drying: the moisture mass content of the above mixed product is dried to 9%, and the dried product is sterilized by steam at 120° C. for 40 minutes to obtain a bacterial agent carrier matrix.

Abstract

The invention discloses a microbial inoculum carrier matrix prepared from cassava residues and a preparation method and application thereof. The invention provides a microbial inoculum carrier matrix. The invention provides application of cassava residues in preparation of a microbial inoculum carrier or microbial inoculums. The cassava residues are cassava starch residues and / or cassava alcohol residues. The microbial inoculum carrier matrix provided by the invention consists of cassava residues and a nutrition material, wherein the nutrition material is made from either corn flour or soybean residues. Proved by experiments, a novel microbial inoculum carrier matrix is prepared from the cassava residues by using the method and has the advantages of sufficient raw materials, low price, simple preparation process, good bacterium carrying effect, environment friendliness and energy saving in raw materials and production processes, convenience in product use, free pollution and the like.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a method for preparing a bacterial agent carrier matrix by utilizing cassava residues. Background technique [0002] Agricultural microbial preparations mainly include pure live bacteria preparations and preparations with organic or inorganic materials as carriers. Among them, the application amount per unit area of ​​pure live bacteria preparation is relatively small in actual agricultural production due to the problem of production cost, and the content of organic matter in most soils cannot meet the needs of mass reproduction of target microorganisms, so the actual application effect is often inconsistent with the test results. big difference. At present, the commonly used solid inoculum carrier in the world is peat, but there are inevitably some defects. Since peat is an organic material with unclear specific components, the quality of peat varies greatly between different orig...
