Abstract

The invention discloses a fulvic acid microbial agent and a preparation method thereof. The fulvic acid microbial agent comprises the following raw materials: fulvic acid powder, a mixed microbial agent protective agent and a biological agent, wherein the mixed microbial agent protective agent comprises the following raw materials: bran, molasses, sodium benzoate and carbendazim. The fulvic acid microbial agent disclosed by the invention has the beneficial effects that the mixed microbial agent protective agent is added into the biological agent, so that the number of effective viable bacteriaof a microbial product is increased, and the storage life of the microbial product is prolonged. The mixed microbial agent protective agent adopted in the fulvic acid microbial agent is composed of aprotective agent (molasses and bran) and a bacteriostatic agent (sodium benzoate and carbendazim), so that infectious microbes in the biological agent can be effectively prevented from growing whilethe biological agent is protected. Therefore, the number of effective viable bacteria in the microbial product is improved, and the storage life is prolonged.

Description

technical field [0001] The invention relates to the technical field of microbial bacterial agents, in particular to a fulvic acid microbial bacterial agent and a preparation method thereof. Background technique [0002] Microbial agent refers to the live bacterial preparation made by processing the fermentation broth of the target microorganisms (effective bacteria) by using porous substances as adsorbents (such as peat and vermiculite) after industrial production and expansion. This bacterial agent is used for seed dressing or root dipping, and has the functions of directly or indirectly improving soil, restoring soil fertility, preventing soil-borne diseases, maintaining the balance of rhizosphere microbial flora, and degrading toxic substances. [0003] Preservatives are food additives used to maintain the original quality and nutritional value of food, and it can inhibit the growth and reproduction of microorganisms. All kinds of preservatives have a certain range of ac...
