Chitosan (Chito-oligosaccharides)
Chitosan is chitosan deacetylated and further broken after the generation of a more useful, and has a good role in new compounds, also known as chitooligosaccharides, amino-oligosaccharides, OS Sterling, etc. It plays an important role in the pharmaceutical, chemical, and pesticide industries.
The application in agriculture has the following aspects:
First, suitable for spraying all the green plants, and has:
1. Form a protective film on the surface of the plant to prevent germ infestation. The occurrence of effective crop diseases reduces the amount of medication and the number of medications. According to statistics, chitosan has a direct bactericidal effect on the diseases of crops, and has a certain killing effect on cotton with the wilt disease, bacterial wilt, virus disease, spot blight, scab, and phytophthora fungal diseases.
2. Absorb all the antibodies from the crop leaves and the disease-resistant “vaccines†of the plants to make the crops immune to all kinds of diseases, especially spraying or perfusing them at the seedling stage of the crops to protect the healthy growth and promotion of the seedlings. Root development and early flower bud differentiation play an irreplaceable role in cultivating strong seedlings.
3. It is an ultra-efficient plant nutrient itself.
4. The effect of flower protection and fruit protection is also very significant. Chitosan is directly involved in the synthesis and operation of photosynthetic products, so that flower development is normal and fruit deformity is reduced.
5. Degradation of pesticide residues, an effective drug residue remover, is the first choice for the production of pollution-free green agricultural products.
6. The most effective plant drug remedy. It is used to relieve the damage caused by the misuse of pesticides and improve the quality of agricultural products.
7. Relieve the phenomena of abnormal growth such as flowering and pressure in the process of crop growth.
8. Increase the fruit harvest period to increase the yield per unit area of ​​the crop.
Second, to improve the physical structure of the soil, make the soil loose and water, form a good granular structure, reduce the number of irrigation, thus promoting the development of the root system, forming a strong root system. Strongly decomposes and degrades harmful chemical substances in the soil and releases harmful chemical residues accumulated in the soil. Adjust the pH of the soil (ie, pH) to be very suitable for crop growth. Therefore, the effect of chitosan on saline-alkali soil is more significant. (especially applied to cotton in saline area)
Third, the application of flowers: reduce the incidence of flowers, promote root growth, so that the leaf color to green, especially in the extension of the flowering period, and make flowers beautiful, improve the ornamental effect of the flower is unique. In the production of high-grade flowers, it can be used as a special flowering period extender and pedicel hardener.
Fourth, in the application of non-academic cultivation, to enter the water circulation system of the non-cultivated cultivation with a certain dilution concentration, to eliminate the damage of the residual salt ions in the nutrient to the root skin and to restore the vitality and vitality of the root system.
5. In the treatment of saline-alkali land, chitosan can be used as a special anti-salt agent.
Six, in the treatment of environmental pollution, chitosan is an efficient impurity flocculant.
VII. Carapace can be mixed with most pesticides, but not as easily as chitin.
