Alginate oligosaccharide is made from natural seaweed and is a natural bioactive substance. In recent years, its application in the agricultural field has gradually attracted attention. Its unique biological activity and promotion of plant growth enable it to show significant effects in increasing crop yield, improving quality and stress resistance.
Agricultural application technology
Alginate oligosaccharide from Wellyou Tech uses deep-sea algae physical wall breaking and genetically engineered bacterial directional lysis technology to directionally degrade the fucoidan in the brown algae cell wall. It is composed of β-D mannuronic acid (ManA) and α-L guluronic acid. Acid (GulA) is connected through 1-4 glycosidic bonds. It has small molecular weight and high purity. AOS is a new generation of seaweed oligosaccharide with more comprehensive nutrients. It can quickly meet the needs of various nutrients for crop growth and can promote plant growth and increase yields. , improve plant stress resistance and anti-virus ability, etc.
Technical advantages of alginate oligosaccharide
1. Low-temperature directed shearing enzymatic hydrolysis
According to the required nutrients, biological enzyme directional shearing technology is used to retain the active ingredients of seaweed while cutting large molecules into small molecules, retaining L-amino acids that can be absorbed by plants to the greatest extent. The high oligosaccharide content ensures nutrition. The diversity and activity of ingredients are more conducive to direct absorption and utilization by crops, significantly improving crop quality.
2. Separation, purification and concentration technology
Using separation and purification technology. It is possible to carry out layer-by-layer screening and step-by-step purification for different nutrient. And it can quickly screen specific target ingredients, remove impurities, separate and purify higher active substances.The product has higher active ingredient content, good water solubility and dispersion properties. At the same time, it makes AOS with stable chemical properties and high safety.
Product positioning of AOS
1. Growth promoter
As signaling molecules, AOS participates in the regulation of plant growth and development. So they can increase the expression of auxin-related genes and increase the chlorophyll content in leaves, thereby enhancing plant photosynthesis, promoting the accumulation of photosynthetic products, and promoting plant growth. It is reflected in the increase in growth indicators such as plant height, leaf area, and root length.
2. Plant protection agent
AOS is an environmental signaling molecule that activates plants’ basic defense and immune systems. It can induce plants to synthesize abscisic acid (ABA) and jasmonic acid (JA). Thereby significantly improving the plant’s drought resistance, cold resistance, high temperature resistance, salt damage resistance, and waterlogging resistance. Salicylic acid (SA) and jasmonic acid (JA) activate the immune system and can fight bacteria and viruses.
3. Soil conditioner
Alginate oligosaccharide can not only promote the growth of beneficial microorganisms in the soil, stimulate the microorganisms to secrete soil amendments, significantly increase the number of bacteria and fungi in the soil, and increase the proportion of beneficial bacteria. But also can increase the activity of FAD enzyme and urease in the soil, promote the growth of microorganisms, and increase the diversity of soil microbial communities.
4. Quality enhancer
Alginate oligosaccharide can bind exogenous Ca2+, increase the activity of nitrate reductase (NR), glutamine synthetase (GS), glutamate dehydrogenase (GDH) and other related metabolic enzymes in plant leaf cells, and accelerate carbon and nitrogen metabolism. It also can promote the synthesis and accumulation of protein, thereby increasing the nutritional value of the fruit and improving the flavor of the product.
