1 .Potassium humate agricultural function is to improve the soil structure.

Potassium humate is a humic substance that affects the properties of the soil and promotes the formation of a more stable agglomerate structure in the soil, which increases the content of aggregates ≥ 0.25 mm in the soil by 10-20%, and increases the organic matter content by 10%. Increase ventilation, which is conducive to the growth of crops.

Enhance the water retention of the soil.

Potassium humate is a hydrophilic colloid with strong water absorption capacity. The maximum water absorption can exceed 500%. The weight of water absorbed from saturated atmosphere can be more than doubled, which is much larger than that of ordinary mineral colloid. Potassium humate inhibits crop transpiration, slows the rate of soil water consumption, and increases soil water content.

Enhance the fertility of the soil.

Potassium humate itself is an organic acid that increases the dissolution of mineral parts of the soil, provides soil nutrients, and increases the effectiveness of nutrients through complexation. As an organic colloid, potassium humate has positive and negative charges, which can adsorb anion and cation, so that these nutrients can be stored in the soil, not lost with water, and improve the utilization rate of fertilizer, which is especially important in sandy land.

Adjust the pH of the soil solution. Potassium humate and potassium humate convert each other to form a buffer system that acts to regulate the pH of the soil solution.

Reduce soil salinity.

The colloidal structure formed by complexation of potassium humate and chelation of metal cations in the soil and its porosity (larger specific surface) can adsorb ions or molecules in the soil solution and reduce the concentration of salt in the soil solution.

Biological action Potassium humate contains a variety of oxygen-containing functional groups, which determine its physiological activity, thereby regulating the life activities, promoting the growth and reproduction of beneficial bacteria, and inhibiting the number of harmful microorganisms; the carboxyl group and phenolic hydroxyl group in potassium humate have certain Inhibit the role of the virus.

2.Improve fertilizer utilization

Potassium humate contains carboxyl, phenolic hydroxyl and other functional groups, has strong complexation, chelation and surface adsorption capacity, can reduce the loss of ammonium nitrogen; increase the movement distance of phosphorus in the soil, inhibit the fixation of water-soluble phosphorus in the soil, so that Ineffective phosphorus is converted into effective phosphorus, which promotes the absorption of phosphorus by roots; potassium humate can absorb and store potassium ions, and the effective potassium content is especially effective for potassium fertilizer. Experiments show that potassium humate can increase the utilization rate of nitrogen, phosphorus and potassium nutrients in fertilizers by more than 20%.Slow release

3.Synergistic pesticides

Potassium humate has the function of surfactant, which can reduce the surface tension of water and emulsify and disperse pesticides. Potassium humate as a colloidal substance with large viscosity and surface area may have strong physical absorption effect on pesticides. Potassium humate itself has antibacterial and anti-disease effects, and the compounding with fungicides is equivalent to the compounding of two pesticides.

4.Stimulating effects on plant growth

Potassium humate is similar to plant endogenous hormones, and can promote seed germination, root growth, and fruit coloration. Specific manifestations: promote root growth and activity, similar to auxin effect; promote seed germination, emergence of seedlings and seedling growth, similar to the effect of gibberellin; make leaves enlarge, thicken, green, delayed senescence of lower leaves, similar The role of cytokinin; the reduction of stomatal, transpiration, similar to the role of abscisic acid; the fruit coloring, maturation, similar to ethylene ripening; promote cell division and cell elongation, differentiation, etc., similar to two The role of the above plant hormones.

5.Potassium humate agricultural function-Improve the quality of agricultural products

Potassium humate enhances the synthesis of sugar, starch, protein, fat and various vitamins. It can stimulate the activity of polysaccharide enzyme, convert polysaccharide into soluble monosaccharide, thereby improve fruit sweetness; increase the ratio of total sugar to nicotine and potassium to chlorine in tobacco leaves, improve the quality of tobacco leaves; increase the total content of watermelon, cantaloupe and other fruits Sugar content and vitamin C content.Enhance crop stress resistance

6.Potassium humate agricultural function -Plant stress resistance index

the content of ABA (abscisic acid: a plant hormone that inhibits growth) in plants. The ABA content of plants will increase under any adverse conditions. Abscisic acid is the “first messenger” that initiates the expression of stress-resistant genes in plants, and effectively activates the anti-reverse immune system in plants. Physiological mechanism of potassium humate to increase plant stress resistance (common): Potassium humate can increase the content of ABA in plan

Potassium Humate: As a plant growth regulator, it is the best component of soil humus, which not only reduces crop burden, increases soil fertility, enriches the matrix of soil bacteria, but also improves crop yield and quality. Agriculture achieves the long-term development goal of increasing production, upgrading and raising land. So as to solve the problem of the quality of crops, so it is a must for agriculture!
