Chitosan oligosaccharide is an oligosaccharide product with a degree of polymerization between 2 and 20 obtained by degrading chitosan by a special biological enzyme technology, with a molecular weight of <3000Da. It is a low molecular weight product with good water solubility, great functional effects and high biological activity.
It is fully soluble in water, easy to absorb and utilized by organisms.It is stable, safe, non-toxic, non-stimulant and easily deliquesce.
Benefits of Agricultural Chitosan
Chitosan-oligosaccharides alter soil flora and promote the growth of beneficial microorganisms. Chitosan-oligosaccharides can also induce disease resistance in plants, creating immunity and killing a variety of fungi, bacteria and viruses. It has good control effect on rice blast, rice blast, tomato late blight and other diseases, and can be developed as biopesticide, growth regulator and fertilizer.
1. Activated rhizosphere state, Chitooligosaccharide can activate the rhizosphere state, dissolve nutrient molecules, and quickly form a soil solution, so that nitrogen, phosphorus, potassium and other nutrients can be effectively absorbed by plants.
2. Strong sterilization ability, Chitosan oligosaccharide can replace seed coating agent, which can protect the normal development of seeds.
3. Improve fertilizer efficiency, Chitooligosaccharide has the characteristics of viscous solution and easy film formation.
4. Boost immunity, Chitosan oligosaccharide is known as "plant vaccine", which shows its effect on crops. Chitosan oligosaccharide preparation can enhance the antiviral ability of plants, change the plant growth mechanism, and enhance the immune function of the regulatory system, thereby ensuring the normal growth and development of plants.
Frequently Asked Questions(FAQ):
What's the difference between Chitin, Chitosan, Chitosan Oligosanccharide?
Chitosan oligosaccharide, also known as Chitosan oligosaccharide, oligosaccharide, Chitosan oligosaccharide, amino-oligosaccharide, etc., is an oligosaccharide product with polymerization degree between 2 and 20 obtained by degrading chitin or chitosan. It is an upgraded product of chitin and chitosan products. Chitosan oligosaccharide is the only positive charge cationic basic amino oligosaccharide in nature, which is animal cellulose. It has the characteristics of low molecular weight, good water solubility, large function and easy to be absorbed.
