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.
It is stable, safe, non-toxic, non-stimulant and easily deliquesce.
Analysis Of Chitosan Oligosaccharide
For large molecular weight chitin, it is insoluble in water, acid and alkali, which directly limits its practical application in many fields. Therefore, IT IS NECESSARY TO USE SOIL APPLICATION method, through the role of soil microorganisms to break CHItin into smaller molecules to be absorbed by crops.

In this way, the advantages of functions and application methods of oligosaccharides with relatively small molecular weights, which can be leaf sprayed, soil applied, coated, and washed, are very obvious, and the agricultural applications of these products are bound to be promising.
Benefits of Agricultural Chitosan
The main performance of chitosan oligosaccharides in agriculture
1. Promote the growth of plants. It mainly includes promoting seed germination, promoting root growth, promoting stem, leaf and fruit growth, accelerating plant growth and development, improving quality, and increasing production and income.
a. to promote seed germination
Oligochitosan can promote the seed germination of crops. After the ryegrass seeds were treated with oligochitosan, the germination index and vigor index increased by 32.64% and 60.47% respectively compared with the control. Its promoting effect is related to promoting the activity of α-amylase in seed endosperm.
b. Promote root growth
After using chitosan oligosaccharides, the roots of the plants are developed, and the hair roots and fibrous roots increase. This is not only beneficial to the growth of the aboveground parts of plants, but also can improve crop tolerance and tolerance to some short-term adverse environmental factors such as drought, low temperature, and early frost, and can also enhance resistance to soil-borne diseases including nematodes.
c. Promote the growth of stems, leaves and fruits
After the use of chitosan oligosaccharides, the photosynthesis of plants can be enhanced, and the photosynthetic rate and efficiency can be improved. Such as chitosan oligosaccharide solution treatment increased the content of chlorophyll and soluble protein in ryegrass seedlings. Therefore, the plants generally show that the stem nodes are thick, the leaves are hypertrophy, the color is bright, the growth is vigorous, and the plants are strong. After using chitosan oligosaccharides, the fruit setting rate of solanaceous vegetables and fruit trees generally increases, and the single fruit increases in weight.
d. Accelerate plant growth and development, improve quality, increase production and income
Oligochitosan treatment can accelerate the process of plant growth and development, and promote early flowering and maturity of crops. Chitooligosaccharides were used to treat cucumber plants. When the cucumber seedlings grew to 3 to 4 true leaves, they were sprayed on the leaves, sprayed once every other week, and repeated three times. The growth of the treated plants was significantly better than that of the blank control, the fruit harvest period could be 3-5 days earlier than that of the blank control, and the yield was also significantly higher than that of the control. Rapeseed yield increased by 4.33%-9.67% after chitooligosaccharide treatment.
2. Disease prevention and disease resistance.
3. Insecticidal effect. Can be used as insecticide and pesticide carrier.
Transfer bacteria or plant chitinase to plants such as tobacco, tomato, lettuce, soybean, potato and sugar beet to obtain transgenic plants that can express chitinase activity. Compared with wild-type plants, transgenic plants are not only resistant to fungi, but also have certain resistance to insects and nematodes. However, the insecticidal activity of chitosan oligosaccharides is not as good as that of chemical pesticides, so it is not suitable to be used directly as conventional insecticides, and can be used as a partial substitute for insecticides or as a synergist of insecticides.
4. Improve the soil.
Using chitosan oligosaccharide as a soil improver is beneficial to the germination, emergence, rooting and growth of plant seeds. Oligochitosan can also promote the growth of actinomycetes in the soil, which is beneficial to absorb nitrogen in the air and convert it into nitrogen available to plants, increasing nutrients. Utilizing the antibacterial ability of chitosan and the function of improving soil, chitosan can be combined with soluble protein (such as collagen) to synthesize liquid soil conditioner. This soil conditioner has proper stability and degradability, and after degradation, it becomes a high-quality organic fertilizer that can be absorbed by crops. And this improver can inhibit the growth and reproduction of pathogenic bacteria in the soil, and can effectively improve the particle structure of the soil at the same time, so it is an ideal liquid soil improver.
