Problems solved by technology

[0003] Most of the existing market fertilizer adding bacteria technology only uses molasses liquid, or directly mixes the bacteria powder into the fertilizer to add the bacteria agent. The effective number of viable bacteria in the fertilizer is generally about 2-1 billion / g, and there are the following disadvantages: The retention rate is low, the initial viable bacteria retention rate is less than 30%; and during the storage process, the viable bacteria retention rate drops sharply again; a large number of microbial deaths lead to high costs

Embodiment 1

[0067] The composition for adding bacteria to fertilizer is composed of polyacrylamide, xanthan gum, sodium carboxymethyl cellulose, hydroxyethyl methyl cellulose, and potassium fulvic acid, and the mass ratio of each substance is 60%: 10% :29% :0.5% :0.5%.

[0068] The method for increasing the number of viable bacteria in the microbial fertilizer comprises: weighing each substance according to the above content, mixing, adding a solvent, and preparing an additive solution with a mass concentration of 5.0%. Use the pump to pressurize through the nozzle arranged at the front end of the wrapping drum, first spray a layer of additive solution evenly on the surface of the organic fertilizer particles, then add the required amount of bacteria powder into the drum, and then spray the organic fertilizer particles with the bacteria powder The surface is evenly sprayed with a layer of additive solution, and the resulting product is sent to the follow-up section as a finished product a...

Embodiment 2

[0072] The composition for adding bacteria to fertilizer is composed of polyacrylamide, xanthan gum, sodium carboxymethylcellulose, hydroxyethylmethylcellulose, protein powder, and trehalose, and the mass ratio of each substance is 45.0%: 18.0% : 15.0% : 20.5% : 1.0% : 0.5%.

[0073] The method for increasing the number of living bacteria in the microbial fertilizer comprises: weighing each substance according to the above-mentioned content, mixing, adding a solvent, and preparing an additive solution with a mass concentration of 3.0%.

Abstract

The invention relates to a composition for additional bacteria of a fertilizer and a method for increasing the viable count in a microbial fertilizer. The composition comprises polyacrylamide, xanthan gum and sodium carboxymethyl cellulose. Therefore, all the components cooperate with one another, and the viable count and the viable count retention rate of a microbial fertilizer can be effectively increased. If the composition is added into a microbial fertilizer, after a 3-month storage period, the effective viable count can be greater than or equal to 3 billion / g, and the viable count retention rate can be greater than or equal to 65%.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a composition for adding bacteria to fertilizers and a method for increasing the number of viable bacteria in microbial fertilizers. Background technique [0002] Beneficial microorganisms in fertilizers have significant effects on improving fertilizer utilization efficiency, repairing and conditioning soil, promoting crop growth, reducing crop diseases, increasing crop yield, and improving crop quality. It will colonize in the soil to form a dominant population, inhibit the growth and reproduction of other harmful microorganisms, and even have an antagonistic effect on some pathogenic microorganisms to reduce the chance of them infecting the rhizosphere of crops; it will produce beneficial to crops during the growth and reproduction process Metabolites can stimulate crop growth and enhance crop resistance to disease and stress. The application of fertilizers con...
