Humic acid is a complex natural macromolecular aromatic weak acid polymer, which belongs to the biological residue, accumulated through a series of processes of microbial decomposition and transformation and geochemistry; mainly from weathered coal, peat, lignite and biological fermentation. Usually contains fulvic acid, brown humic acid, black humic acid (HU-micAcid referred to as HA), the main elements: C, O, N, H, S. Its active group contains: carboxyl, hydroxyl, alcoholic hydroxyl, enol, sulfonate, amino, sulfhydryl, carbonyl, methoxy and other genes, with ion exchange, complexation, chelation, flocculation, dispersion, bonding And many other features.
I. Improved soil
Humic acid is a porous substance that can improve the structure of soil aggregates, regulate soil water, fertilizer, gas and heat, increase soil exchange capacity, regulate soil pH, and achieve acid-base balance. Its adsorption and complexation reactions can reduce harmful substances in the soil (including residual pesticides, heavy metals and other toxic substances), improve the natural purification ability of the soil and reduce pollution. At the same time, due to the colloidal properties of humic acid, the microbial population in the soil can be improved, and the growth and reproduction of the beneficial bacteria are suitable.
Second, stimulate the growth of fruit trees,
Humic acid contains a variety of active genes, which can enhance the activity of catalase and polyphenol oxidase in fruit trees, stimulate the physiological metabolism of plants, promote the radiance of saplings, roots, roots are developed, stems and branches are robust and luxuriant. Photosynthesis is strong, accelerating the transfer and absorption of nutrients.
Third, increase fertilizer efficiency
Humic acid contains active groups such as carboxyl groups and phenolic hydroxyl groups, and has strong exchange and adsorption capacity, which can reduce the loss of ammonium nitrogen and increase the utilization rate of nitrogen fertilizer. Degraded nitro-humic acid can increase the distance of phosphorus movement in the soil, inhibit the fixation of water-soluble phosphorus in the soil, and promote the absorption of phosphorus by roots. The functional group of this product can absorb and store potassium ions, so that the potassium fertilizer can be slowly decomposed and the content of quick-acting can be improved. This product can chelate reaction with insoluble metal ions such as calcium, magnesium, copper and zinc to promote the absorption of trace elements by fruit trees. It also promotes the growth of microorganisms.
Fourth, enhance the resistance to stress, improve the quality of the fruit
Humic acid can reduce the opening degree of leaf stomata, reduce leaf water evaporation, adjust water volume, improve the water condition of plants, and ensure the normal growth of fruit trees under drought conditions. Because it is an amphoteric colloid, it has a large surface activity and has an inhibitory effect on fungi, which can enhance the cold resistance of fruit trees and reduce pests and diseases.
Humic acid can form complexes or chelates with trace elements, regulate the ratio of a large number of elements to trace elements, strengthen the synthesis of sugar, starch, protein and various vitamins, and convert polysaccharides into soluble elemental sugars. The synthesis and accumulation of starch and protein increase the fruit and increase the sugar content.
