Preparation method of novel photosynthesis accelerant combined nitrogen-magnesium foliar fertilizer

Abstract

The invention discloses a preparation method of novel photosynthesis accelerant combined nitrogen-magnesium foliar fertilizer. The preparation method comprises the following steps: carrying out amplification culture on photosynthetic bacteria to obtain amplification culture bacterium liquid; then carrying out cell crushing on the amplification culture bacterium liquid; carrying out secondary impurity removal to obtain supernatant; taking the extracted supernatant as a solvent and adding a nutrient element main body; after mixing, stirring and dissolving, adding mixed oil and a surfactant; emulsifying in a high-pressure homogenization machine to obtain emulsion. According to the preparation method disclosed by the invention, culture liquid containing photosynthetic bacterium intracellular fluid is used as a diluting agent of the foliar fertilizer, and the photosynthetic bacteria are bacteria with a function of producing aminolevulinic acid; the culture liquid containing the photosynthetic bacterium intracellular fluid has the effect of simulating an environment in a photosynthetic bacterium cell, and an active substance aminolevulinic acid is easy to form; the preservation effect and the acting effect are improved.

Description

technical field [0001] The invention relates to the technical field of modern agricultural fertilizers, in particular to a preparation method of a novel photosynthesis accelerator combined with nitrogen and magnesium foliar fertilizer. Background technique [0002] Photosynthetic bacteria are the oldest prokaryotic microorganisms on earth and play an important role in the material cycle and transformation of carbon in nature. Photosynthetic bacteria contain 65% protein and other important life active substances such as coenzyme Q, B vitamins, folic acid and biotin, etc., and are widely used in the production of single-cell protein, aquaculture, agriculture and animal husbandry, food coloring, energy development, Health care, medicine and other fields have broad prospects. [0003] Aminolevulinic acid, an analogue of porphyrin, (ferrous)heme, and vitamin B12. In recent years, studies have found that ALA, as a pollution-free green herbicide and photodynamic agent, can be use...

AI Technical Summary

Problems solved by technology

[0004] Photosynthetic bacteria are the most common, lowest cost, and easiest to achieve large-scale production of aminolevulinic acid-producing bacteria. Therefore, photosynthetic bacteria are often used to produce aminolevulinic acid. Huge beneficial effect, often used as an additive of foliar fertilizer, but as an organic active substance, the sustainable effect of aminolevulinic acid in the natural environment is not very good, it is affected by temperature, pH and light intensity, etc.
