Liquid biological potassium fertilizer protecting agent

Abstract

The invention belongs to a fertilizer protecting agent, in particular to a liquid biological potassium fertilizer protecting agent, which is formed by a preparation A and a preparation B, wherein the weight of the preparation A is equal to the weight of the preparation B; the preparation A is formed by the following components in parts by unit weight: 5-10 parts of zinc sulfate, 1-5 parts of boric acid, 1-5 parts of manganese sulfate and 80-90 parts of water; and the preparation B is formed by the following components in parts by unit weight: 1-5 parts of sodium carboxymethylcellulose, 1-10 parts of sodium molybdate and 85-95 percent of water. The liquid biological potassium fertilizer protecting agent solves the problems that liquid biological potassium fertilizers easily become black and smelly after the liquid biological potassium fertilizers are filled and contaminated by bacteria in the prior art. The liquid biological potassium fertilizer protecting agent has the advantages that the problem that the liquid biological potassium fertilizers are easily contaminated by bacteria and deteriorated after the biological potassium fertilizers are filled can be effectively solved, the protecting agent has no harm to crops and human bodies, the influences on the growth of the crops and the application of the potassium fertilizers are small and the like.

Description

technical field [0001] The invention belongs to a fertilizer protective agent, in particular to a liquid biological potash fertilizer protective agent. Background technique [0002] Microbial fertilizer is a new type of fertilizer. It is a biological product containing specific active microorganisms. There are two types of dosage forms: liquid and solid. Biological potassium fertilizer is a microbial fertilizer in liquid dosage form. The active microorganisms contained are generally Bacillus colioids. The production process is as follows: Preservation of strains in test tubes on inclined planes→Seeds in Kjeldahl bottles→seed tanks→fermentation tanks→fermentation products→liquid canning→finished products. In the first half of the process, that is, the slant bacteria are always operated aseptically until filling, but due to the limitation of space and equipment during filling, most production enterprises cannot perform strict aseptic operation at present. During the filling p...

AI Technical Summary

Problems solved by technology

In the first half of the process, that is, the slant bacteria are always operated aseptically until filling, but due to the limitation of space and equipment during filling, most of the production enterprises currently cannot achieve strict aseptic operation

During the filling process of biopotassium fertilizer, microorganisms in the air can easily enter the bottle body. Since the fermentation liquid of biopotassium fertilizer contains rich nutrients, miscellaneous bacteria are easy to breed. During the shelf life of the product, a small amount of products will turn black The phenomenon of deodorization seriously affects the production and sales of biological fertilizers

In order to stabilize product quality, it is necessary to study the production process of new biological potash fertilizers. One of the effective methods is to add protective agents before packaging liquid biological potassium fertilizers. At present, the more effective protective agents are single chemical protective agents, such as sodium benzoate, sodium nitrite, etc. , these substances all have certain toxicity and are unsafe to crops and the environment
