Preparation method of selenium-rich biogenic nanometer antibacterial growth regulator

Abstract

The invention discloses a preparation method of a selenium-rich biogenic nanometer antibacterial growth regulator. The regulator prepared by the method disclosed by the invention is used for soaking mung bean seeds in comparison to a compound agent consisting of oligochitosan, sodium selenite and agricultural streptomycin under the same concentration condition. Comparison of the test results shows that the germination rate of mung bean sprouts treated with nanometer preparation of the same concentration is increased, the germination potential is increased by 20.8 percent, the water content is increased by 14.1 percent, the selenium content is increased by 83.6 percent, and the acting effect of a low-concentration nanometer preparation is superior to a high-concentration agent. Meanwhile, the particle diameters of nanoparticles of the regulator prepared by the method are less than 500 nanometers and are smaller than that of the agent, the nanoparticles are dispersed uniformly, a phase is pure, and impurities do not exist. Thus, by using the prepared agent prepared by the method, the functions of the agent (oligochitosan, sodium selenite and agricultural streptomycin) are kept, the acting effect is enhanced, the using amount is reduced, so that the prepared agent is very high in application value and very wide in market prospect.

Description

Technical field [0001] The invention relates to a preparation method of a growth regulator, in particular to a preparation method of a selenium-rich biological source nano antibacterial growth regulator. Background technique [0002] Nano biological preparations are the use of nanotechnology to treat biologically active substances of biological origin, change their particle size, and then improve the physical and chemical properties of the substances to increase their absorption and transformation efficiency, increase bioavailability, and improve crop quality to a certain extent , The role of increasing output. [0003] Chito-oligosaccharide (CS), a linear or branched chitosan hydrolyzed oligomer formed by 2-12 monosaccharides connected by glycosidic bonds, is the only basic amino oligosaccharide that exists in large quantities in natural sugars , As a biologically derived oligosaccharide, compared with chitin and chitosan, it has more unique functional properties: water solubilit...
