Chitosan Oligosaccharide Seed Treatment Combination

Formula: Compound Amino Oligosaccharide Solution : Nutrient Solution Volume Ratio=1 : 2

       Among them, the Compound Amino Oligosaccharide Solution is prepared by 4% Chitosan Acetic Acid Solution with 1% Chitosan Oligosaccharide Solution according to the volume ratio of 1 : 1;

       Among them, the contents of each component in the Nutrient Solution were: Lime Nitrate 70g/L、Potassium Nitrate 45g/L、Magnesium Sulfate 50g/L、Monopotassium Phosphate 35g/L、 Diethylamine Tetraacetic Acid Disodium 6g/L、Ferrous Sulfate 4g/L、Boric Acid 4g/L、Manganese Sulfate 1.5g/L、Bluestone 0.05g/L、Zinc Sulfate 0.1g/L、Key Acid 0.16g/L.

Use-method: The seed treating agent diluted 20 times, evenly spray and stir the seeds, cool 3-6 hours then sow.

Use-case 1: Experiment in Xinjiang area, treating the seed of spring wheat with different methods, seedling growth investigation:

一、The Composition of the Chitosan Oligosaccharide Growth Regulator

Formula: Chitosan Oligosaccharide: 50g, Content 90%、DAC>90%, Molecular Weight<3000Da;

         Tea saponin powder: 15g, Content >98%;

         Trace element mixture: 5g, each gram of trace element mixture contains Manganese Sulfate 0.15g, Zinc Sulfate 0.15g, Magnesium Sulfate 0.15g, Bluestone 0.05g, Boric Acid 0.15g, Ammonium Molybdate 0.15g, re-add L-alanine 0.2g, L-methionine 0.2g, L-threonine 0.2g, L-aspartate 0.2g, L-tyrosine 0.2g, L-tryptophan 0.2g;

        After all dissolved, constant volume to 1000ml.

Use-method: The formula composition diluted 500~1000 times, sprayed on the surface of the plant, after the first application, re-application 15-20 days per interval, after three times the best effect can be achieved.

Use-case 1:

   The growth regulator of this formula and some commercially available growth regulator were sprayed on the leaf of tobacco、pepper、tomato, etc, the preventive effect of viral disease:
