Agricultural Chitosan uses crab shells and shrimp skins as the basic raw materials, and is extracted to prepare chitosan, which is then degraded by biological enzyme technology. The degree of polymerization is between 2-20, and it is combined with β-1 and 4, with small molecular weight, good water solubility, high activity, and can be quickly absorbed by plants, and has a very unique biological function.
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, and its effect is 14 times that of chitosan.
It is stable, safe, non-toxic, non-stimulant and easily deliquesce.
Benefits of Agricultural Chitosan
The main performance of chitosan oligosaccharide in agriculture
1. Improve crop disease resistance
Treating plants with chitin and its derivatives before the plants are infected can produce a sensitizing effect, and the treated plants can show a higher preventive effect than normal plants when they are infected by diseases and insect pests again. It can be toxic to certain fungi, bacteria, viruses and pests, and induce plants to activate their defense systems.
2. Activation of the plant's own innate immune system
Chitosan oligosaccharide can bind to receptors on plant cells, stimulate the production of resistance signal molecules, and through signal transduction, stimulate the expression of resistance genes and produce resistance substances, so as to achieve the purpose of disease control.
3. Improve crop stress resistance
In the process of agricultural production, drastic changes in the external environment will cause huge irreversible damage to plants. When the weather is abnormal, the citrus and grapes in the south will also suffer from freezing damage or chilling damage, resulting in weak seedlings, wilting leaves, falling flowers and fruits, and deformed fruits. quality. Chitooligosaccharide can increase the content of cold-resistant substances such as soluble protein and soluble sugar, reduce the level of membrane lipid peroxidation and the increase of membrane permeability, maintain a high photosynthetic intensity of crops, and effectively resist the damage of low temperature to crops.
4. Improve rhizosphere microbial population and inhibit nematodes
Many organisms in the soil (such as plants, bacteria, fungi, etc.) can produce chitinase, which breaks down the chitin tissue in fungi and insects and destroys its structure. Adding chitosan to the soil promotes the reproduction and activity of microorganisms, these microorganisms produce more chitinase, antibiotics and toxins, or directly compete with harmful organisms for nutrition, or directly parasitize, or activate plant defense systems, etc. In this way, the control level of pests with chitin composition structure is increased.
5. Stimulates rooting of crops
After the chitosan oligosaccharide is absorbed by the plant, it induces the plant to produce auxins such as indole acetic acid and gibberellin, which stimulates the root development of the plant. Seed dressing with sugar-sugar water can stimulate early germination of crops. In the seedling stage of crops, there are many and long capillary roots. In the middle and late stages, potatoes have a strong absorbing root system, which can make better use of fertilizer and water, and become the basis for crops to resist drought and increase yield.
6. Increase crop yield and improve the quality of agricultural products
Because chitosan oligosaccharide stimulates the root system, promotes early growth, and improves the photosynthetic efficiency of leaves, especially under the condition of insufficient light in the greenhouse, the yield of plants is significantly increased.
After spraying chitosan oligosaccharide solution 3 times in the growing season, the quality of citrus has been greatly improved, which is mainly reflected in the increase of vitamin C content by 20%, the increase of soluble total sugar by 13%, the increase of soluble solid content by 6%, and the increase of solid-acid ratio. 52%, and citrus titratable acid content decreased by 21%. Similar results were obtained on grapes, watermelon, and tomatoes.
