1.Regulate enzymatic reactions and enhance plant life activities.
Enzymes are biological catalysts for plant life activities, and the size of the enzyme's effect is expressed by the activity of the enzyme. Fulvic acid can stimulate the activity of polysaccharidase, hydrolyze the pectin in the young cell wall, soften the cell wall, make the cell easy to elongate and divide, and grow vertically and horizontally. Therefore, it has a significant effect on promoting the growth of young cells in new tissues, and its effect on the root growth point is particularly significant.
Fulvic acid contains a large amount of carboxyl groups that can inhibit the activity of auxin oxidase, reduce the destruction of auxin, and increase the content, which is beneficial to the growth of roots and stems, so that crops can root quickly, have more secondary roots, increase the amount of roots, and elongate the root system, so that the crop can absorb water and nutrients.
Fulvic acid can promote the activity of sugar invertase, starch phosphorylase and some enzymes related to protein and fat synthesis, increase the synthesis and accumulation of sugar, starch, protein, fat, nucleic acid, vitamins and other substances, and promote the activity of transferase, accelerate the movement of various metabolites from stems, leaves or roots to fruits and grains, and have a direct impact on increasing and improving the yield and quality of crops.
2.Increase chlorophyll content and promote photosynthesis
Fulvic acid can promote the absorption and movement of trace elements in plants, significantly increase the chlorophyll content in leaves, and inhibit the activity of protease, slowing down the decomposition of chlorophyll.
Fulvic acid can increase the activity of protective enzymes and reduce the damage of active oxygen to chlorophyll. These are all conducive to maintaining and increasing chlorophyll content, promoting photosynthesis, and increasing the accumulation of photosynthetic products.
