Fulvic acid is a kind of small molecule formed by a series of decomposition and transformation of plant and animal remains. It can dissolve in alkali and dissolve in acid and water.The company's yellow rot is the extract from straw.
Fulvic acid is a colloid organic matter, it can make the soil loose, adsorption of water, air humidifying, keep moisture, drought control, make the soil has good water, gas and heat conditions, suitable for seed germination and seedling growth.
Ⅱ Improved saline-alkali land
Fulvic acid with small molecular weight, high activity, which can adsorb harmful cations in the soil, thereby reducing the concentration of salt in the soil, reduce the harm to the seeds and seedlings because of salt, Improve saline alkali soil.
Ⅲ Drought resistant, cold resistant
1, Spraying fulvic acid into the leaves of plants, it can close the stomata of plants, reduce plant water transpiration.
2, Fulvic acid with deep color,it is conducive to absorb solar energy; fulvic acid is decomposed by microorganism to release heat, it can rise the earth temperature, thus playing a role in cold resistance.
Ⅳ Pest control
Fulvic acid can increase the activity of enzymes in plants and increase the resistance of plants.
Ⅴ Prevent heavy metal pollution
Fulvic acid is involved in the ion exchange reaction in the soil, and it can adsorb the heavy metal ions in the soil to prevent them from entering the biological cycle.
Ⅵ improve the fertilizer efficiency
1. Nitrogen fixation: nitrogen is applied to the soil, which can easily evaporate into the atmosphere or With soil erosion into rivers.Fulvic acid can absorb nitrogen in soil, reduce its volatilization and loss, and improve utilization rate.
2. Phosphorus removal: phosphorus is applied to soil and is easily fixed by soil.Fulvic acid can liberate phosphorus from soil by chelating with phosphorus elements, which can be used for the absorption of plants and improve the utilization rate of phosphorus.
3. Activated potassium: potassium in the soil is mostly in the form of potassium, and cannot be absorbed directly by the crops.Fulvic acid can convert insoluble potassium into soluble potassium through the ion exchange function, increase the available potassium in soil, and increase the utilization rate of potassium.
4, Tiny fertilizer: Fulvic acid can react with insoluble trace elements to produce humic acid chelate elements with good solubility and can be absorbed by crops, so as to absorb trace elements in roots and leaves.
Ⅶ promoting crop growth and development
1 Fulvic acid stimulates root growth and eventually increases the ability of crops to absorb water and nutrients.
2, Fulvic acid stimulated the growth of vegetative parts in the upper part of the plant.The performance is high plant, stem thick, leaf thickness and so on;
3, Fulvic acid has a good effect on tillering, reduce sterile grain rate, it can increase grain weight, increase grain capacity.
Ⅷ Adjust soil pHFulvic acid has many functional groups, which can be combined with acid and alkali, and can adjust the pH of soil according to crop requirement.
