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 the fertilizer is composed of polyacrylamide, xanthan gum, sodium carboxymethyl cellulose, hydroxyethyl methyl cellulose, 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 includes: weighing each substance according to the above content, mixing, adding a solvent, and preparing an adjuvant solution with a mass concentration of 5.0%. Use the pump to pressurize through the nozzle arranged at the front end of the wrapped drum, firstly spray a layer of auxiliary solution on the surface of the organic fertilizer particles evenly, then add the required amount of bacteria powder into the drum, and then spray the organic fertilizer particles with the bacteria powder on it. A layer of auxiliary solution is evenly sprayed on the surface, and the obtained product goes out of the wrapping drum to be the finished ...

Embodiment 2

[0072] The composition for adding bacteria to the fertilizer is composed of polyacrylamide, xanthan gum, sodium carboxymethyl cellulose, hydroxyethyl methyl cellulose, protein powder, 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 viable bacteria in the microbial fertilizer includes: weighing each substance according to the above content, mixing, adding a solvent, and preparing an adjuvant solution with a mass concentration of 3.0%. Use the pump to pressurize through the nozzle arranged at the front end of the wrapped drum, firstly spray a layer of auxiliary solution on the surface of the organic fertilizer particles evenly, then add the required amount of bacteria powder into the drum, and then spray the organic fertilizer particles with the bacteria powder on it.

Abstract

The invention relates to a composition for adding bacteria to fertilizers and a method for increasing the number of viable bacteria in microbial fertilizers. The composition comprises: polyacrylamide, xanthan gum and sodium carboxymethylcellulose. As a result, each component cooperates and cooperates with each other, which can effectively increase the number of viable bacteria and the retention rate of viable bacteria of the microbial fertilizer. When the composition of the present application is added to the microbial fertilizer, after a storage period of 3 months, the number of effective viable bacteria can be greater than or equal to 3 billion / g, and the retention rate of viable bacteria 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 a fertilizer and a method for increasing the number of viable bacteria in a microbial fertilizer. Background technique [0002] Beneficial microorganisms in fertilizers have significant effects on improving fertilizer utilization, repairing and conditioning soil, promoting crop growth, alleviating crop diseases, increasing crop yield, and improving crop quality. It will colonize 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 crops during the growth and reproduction process. The metabolites can stimulate crop growth and enhance the disease resistance and stress resistance of crops. The application of fertil...
