The scientific name of chitosan oligosaccharide is B-1,4-oligosaccharide glucosamine,It is an oligosaccharide product obtained by degrading chitosan,by special biological enzyme technolo-gy. Molecular weight s3000Da, good water solubility, great function and low molecular weight product with high biological activity.

It has a higher solubility that chitosan does not have, and is completely soluble in water.It has many unique functions such as being easily absorbed and utilized by living organisms,Its effect is 14 times that of chitosan.Chitosan oligosaccharide is the only positively charged cationic basic amino oligosaccharide in nature and is the animal cellulose.


1.lmprove soil environment
Chitosan oligosaccharide can be used as an inducing fungicide to change soil flora and promote the growth of beneficial microorganisms. Chitosan oligosaccharide can also induce plant disease resistance, and have immune and klling effects on a variety of fungi, badteria and viruses. The mass reproduction of microorganisms can promote the fomation of soil aggregate structure, improve the physical and chemical properties of the soil, enhanoe the pemeability and the ability to retain water and ferilizer; thus providing a good soil micro-ecological environment for the root system, so that various nutrients in the soil are effec-fively activated.,can improve nutrient uilization and reduce the amount of chemical ferlilizers.
2.Induce plant disease resistance and stress resistance
Chitosan oligosaccharide, as a crop resistance agent, can effetively induce plant disease resistance,enhance the plant's defense abiliy against diseases, resist cold, high temperatuire, drought and waterlog-ging, salinity, fertilizer damage, air damage, resistance to Nutitional imbalance. Induced lignin formation Lignin is the main component of the secondary cell wall of plant vascular tissue, which itself is resistant to microbial degradation. Chitosan oligosaccharide can induce lignification around the infected point of plants, forming a physical barrier, thereby preventing or delaying the growth and difusion of pathogens to surrounding nomal tissues, and enhancing the disease resistanoe of plants.
3. Can be used as seed coating agent, seed dressing agent
Plant growth regulators and antibacterial agents can induce plants to produce PR proteins (a type of protein produced by plants stimulated and stressed by pathogens or other factors) and phytochemicals, using amino oligosaccharides as the basic components to distribute chemical fertilizers, Development of new seed coating agents with trace elements.
4.Plant functional fertilizer
Chitosan oligosaccharide combines with cell membrane receptors, transmits electrical signals, activates various immune pathways, thickens the cell wall, increases various resistant substanoes and active ingre- dients in the cells, and stimulates crops to improve resistance and promote growth. effect Chitosan oligo-saccharides are used in combination with acquired nutrients to achieve the best results.
