Functions of biostimulant fulvic acid
Fulvic acid: It is the water-soluble part with the smallest molecular weight and the highest content of active groups in humic acid. Its functional groups interact with each other, reflecting a variety of specific physical and chemical properties. After entering the plant body, it can play a variety of physiological functions, acting on the metabolism of the plant body by inhibiting or activating enzymes, reflecting a significant stimulating effect, and exerting a therapeutic effect through the secretion, regulation and improvement of endogenous hormones and immune function.
Functional characteristics
Fulvic acid has the general characteristics of humic acid:
1) It has a small molecular weight and is easily absorbed and utilized by organisms;
2) It has a large content of functional groups, which is more physiologically active than general humic acid and has a stronger complexing ability for metal ions;
3) It can be directly soluble in water, and its aqueous solution is acidic.
Fulvic acid is a broad-spectrum plant growth regulator, also known as a biostimulant. It has the functions of promoting plant growth, especially properly controlling the opening of crop leaf stomata, reducing transpiration, and playing an important role in drought resistance. It can improve stress resistance, increase production and improve quality.
Functions and effects
★ Stimulate crop activity: unknown growth-promoting factors with high biological activity can enhance the oxidase activity and other metabolic activities of crop cells. Although fulvic acid does not contain hormone substances, it shows similar effects to chemically synthesized auxins, cytokinins, abscisic acid and other plant hormones during use, and has a certain regulatory effect on plant growth and development;
★ Enhance crop stress resistance: fulvic acid has the function of cold and drought resistance;
★ Slow-release fertilizer: improve the use of fertilizers and pesticides, and improve the soil aggregate structure;
★ Chelate trace nutrients: strong chelating ability, improve the absorption and operation of plant trace elements, so that they can be better used by plants;
★ Enhance disease resistance: fulvic acid is used as a pesticide synergist to improve the prevention and control effect, but it cannot replace pesticides;
★ Anti-flocculation, buffering, good solubility: strong interaction with metal ions. Its anti-flocculation ability is significantly higher than that of humic acid and similar products. It is soluble in any acidic or alkaline water with a pH range of 1 to 14. It will flocculate without precipitation in high-calcium and magnesium hard water saturated brine, and it has good stability and strong electrolyte resistance.
