Agricultural Grade Chitosan Oligosaccharide, Chitosan Oligosaccharide Powder, Oligochitosan Powder
chitosan oligosaccharide also named chitooligosaccharides COS, oligochitosan.
Chitosan oligosaccharides are oligosaccharides with a degree of polymerization of less than 20, which is made of marine biological resources like shrimp, crab shells by the degradation of biological enzymes. It is "positively charged natural oligosaccharides" in nature. Chitosan oligosaccharides also is known as amino-oligosaccharin in agriculture.
Chitosan oligosaccharides effects:
1. Promote plant growth and development, improve crop quality
Chitosan oligosaccharides can accelerate the growth and development of plants and improve crop yields. Spray chitosan oligosaccharides solution at the seedling stage and flowering stage of corn, spraying once every week, the yield of treated plants is significantly higher, and the yield is increased by 8.42%.
Chitosan oligosaccharides can also promote the production of secondary metabolites of plants such as salvia miltiorrhiza, oregano, and artemisia annua, and increase the production of tanshinone, polyphenols. Spraying the chitosan oligosaccharides solution during apple flowering stage, the content of vitamin C was Increased by 10.5%.
2. Promote the growth of plant growth organs and reproductive organs
Chitosan oligosaccharides can promote the growth of plant roots, stems, leaves, and fruits, and improve the yield and quality of crops.
3. Resist various crop diseases
Chitosan oligosaccharides have a certain control effect on tobacco plant mosaic disease, tomato bacterial wilt, cotton wilt, watermelon wilt and other plant diseases, and have broad-spectrum antibacterial properties. The treatment of tobacco plants infected with tobacco mosaic disease with chitooligosaccharides showed that the control effect was 87.5%
4. Has the effects of cold resistance and drought resistance
Chitosan oligosaccharides can improve the stress resistance of crops, stabilize the cell membrane structure of crops in cold, drought, high salt and other adversities, effectively regulate stomatal development, increase crop water and water retention capacity, promote photosynthesis, improve the activation performance of various enzymes and carbon water The metabolism of the compound induces crops to increase stress resistance.
5. Promote seed germination and seedling growth
Chitosan oligosaccharides can promote the germination of crop seeds. The treatment of cucumber seeds with chitooligosaccharides increased the germination rate and germination index by 15%
