potassium humate

potassium humate composition and efficiency

potassium humate composition and efficiency need to make clear The main components of potassium humate include trace elements, rare earth elements, plant growth regulators, virus inhibitors and other nutrients, which make nutrients more abundant and more reasonable, thus avoiding various physiological physiology caused by lack of elements. The occurrence of the disease.

The main effects of potassium humate are as follows:
Potassium humate can activate the squash soil, promote the physiological metabolism of various melons, fruits and vegetables and field crops, promote the development of roots and flourish stems and leaves.

otassium humate can be applied, applied, chased, applied or chased by about 20-30 kg, which can save all kinds of fertilizers, and can make fruits and vegetables and various field crops mature for about 10 days in advance, increasing production by 20 %the above.

It can prolong the fresh-keeping period and picking period of fruits and vegetables, prevent falling flowers and fruit drop, increase the sugar content of fruits and improve the quality of fruits.

  1. Potassium humate improves soil aggregate structure, loosens soil, improves soil water retention and fertilizer retention capacity, regulates pH value, reduces heavy metal content in soil, and reduces the damage of salt ions to seeds and seedlings.
  2. Potassium humate fixes nitrogen, dissolves phosphorus, and activates potassium. Especially for the potash fertilizer, the synergy is particularly obvious, which plays a role in increasing roots and strengthening seedlings, resisting heavy mites, resisting diseases and improving crop quality.
  3. Potassium humate enhances the adhesion and rapid absorption capacity of plant roots, especially for physiological diseases caused by the lack of trace elements.

Potassium humate meets the requirements of agricultural production – potassium humate can be adapted to local conditions, meet the needs of soil production under different time and space, zone and natural environment conditions, and meet the current agricultural production status and requirements.

Potassium humate rapidly increases soil fertility – the soil organic matter is less than two or three years old, and more than one hundred years. Industrial development using potassium humate can shorten the time of decomposing organic matter, benefiting it in the current year and even benefiting in the current season.
The combination of organic and inorganic humic acid potassium is good. Potassium humate can be combined with large, medium and micro nutrients and beneficial elements. Once combined, the best state of matching can be achieved. In the case of equal nutrients, potassium humate increased by an average of 10 percentage points or more, equivalent to a net increase of 30% to 40%.

Potassium humate can repair heavy metal pollution in soil – potassium humate can not only reduce the content of heavy metal pollutants in the soil, but also improve the “self-repairing” function of the soil, which is an excellent choice for soil remediation.

Potassium humate benefites to quality of agricultural products

Potassium humate benefites to quality of agricultural products

Potassium humate improves the quality of agricultural productspromotes the activity of sugar invertase, starch phosphorylase and some enzymes involved in protein and fat synthesis, and increases the synthesis and accumulation of sugar, starch, protein, fat, nucleic acid, vitamins, etc., and promotes transferase.

Regulate enzymatic reactions and enhance plant life activities


Enzymes are biocatalysts for plant life activities, and the size of the enzyme is expressed by the activity of the enzyme. Potassium humate can stimulate the activity of polysaccharide enzyme, so that the cell wall of the young cell wall is hydrolyzed, the cell wall is softened, and the cells are easy to elongate and divide, and grow longitudinally and laterally, thus having a significant effect on promoting the growth of young tissue cells.

The role of the growth point is particularly significant. Potassium humate contains a large amount of carboxyl groups, which can inhibit the activity of auxin oxidase, reduce the damage of auxin and increase the content, which is beneficial to the growth of roots and stems, making the roots of crops fast, secondary roots, roots increased, and roots are elongated. The crops absorb water and increase nutrient capacity; increase cell membrane permeability and promote nutrient absorption.

Potassium humate promotes the activity of sugar invertase, starch phosphorylase and some enzymes involved in protein and fat synthesis, and increases the synthesis and accumulation of sugar, starch, protein, fat, nucleic acid, vitamins, etc., and promotes transferase.

The activity of accelerating the metabolism of various metabolites from stems or roots to fruits and grains has a direct effect on improving and improving the yield and quality of crops; it can also stimulate the activity of polysaccharide enzymes and convert polysaccharides into soluble monosaccharides, thereby improving The sweetness of the fruit;

Increase the ratio of total sugar to nicotine and potassium to chlorine in tobacco leaves, improve the quality of tobacco leaves; increase the total sugar content and vitamin C content in fruits such as watermelon and cantaloupe.

Improve chlorophyll content and promote photosynthesis

Potassium humate can promote the absorption and operation of trace elements in plants, so that the content of chlorophyll in leaves is significantly increased, and the activity of proteolytic enzymes can be inhibited, and the decomposition of chlorophyll is slowed down.

Potassium humate can increase the activity of antioxidant enzymes. The antioxidant enzyme system can remove excess reactive oxygen species in cells and reduce the damage of chlorophyll by reactive oxygen species. These are beneficial to maintain and improve chlorophyll content, promote photosynthesis, accelerate sugar accumulation, promote the synthesis of nucleic acids, chlorophyll, vitamins, antibiotics, and improve plant quality and health.

Enhance breathing

Because the potassium humate molecule is small, it is easy to enter plant cells. As a donor of polyphenols or a receptor for hydrogen, it directly affects the redox process of plants, promotes the synthesis of adenosine triphosphate (ATP), and acts as a respiratory catalyst. Effect;

potassium humate can also enhance the activity of respiratory enzymes, especially the activity of terminal oxidase, thereby enhancing respiration. Respiratory effects are strong, thereby promoting root absorption and material synthesis.

4.Promote the absorption and transportation of mineral elements

Many trace mineral elements such as Fe, Cu, Zn, Mn, B, Mo, etc. are components of enzymes or coenzymes involved in plant metabolic activities, or have important effects on the activity of various enzymes and plant stress resistance, and some are cellular structural substances. The composition.

The active groups of potassium humate (including carboxyl groups, hydroxyl groups, and certain groups containing P, O, N, and S) are generally electron donors, and are easily associated with many electron acceptors (multivalent metal ions, organic groups). Or ionic) constitutes a coordination compound, referred to as a complex or chelate. For example, potassium humate-Zn, potassium humate-Mn, potassium humate-Fe, etc., are mostly complex (chelating) substances.

In addition, potassium humate also has ion exchange properties, and active hydrogen ions (H+) on carboxyl and phenolic hydroxyl groups are easily replaced by monovalent cations (K+, Na+, Li+, NH4+) and some divalent metal ions (Ca2+, Mg2+, Fe2+, etc. Replacement to form humic acid potassium salts and the like. This effect of potassium humate increases the absorption of many trace elements by crops.

Potassium humate enhances crop stress resistance

Potassium humate enhances crop stress resistance,Plant stress resistance index (one): 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.

The standard oxidation-reduction potential (E0) of potassium humate is about 0.7 V, which is equivalent to the electrode potential of the semiquinone radical. Therefore, it is considered that the redox property of potassium humate is caused by the mutual conversion of -semiquinone-phenol. In fact, the carbonyl, alcoholic hydroxyl, amino, nitro, and even fatty carbon structural sites in potassium humate may participate in the redox reaction.

This property of potassium humate not only regulates the redox concentration ratio of soil minerals (αOx/αRrd), stimulates microbial activity, regulates the physiological activity of plants, but also changes in geochemistry, heavy metals and organic poisons (oil, polycyclic The migration and toxicity of aromatic hydrocarbons, phenols, dyes, pesticides, etc. also have an effect.

Experiments show that the presence of potassium humate can keep the effective oxidation-reduction potential (Eh) of the soil environment in the optimal range (0.2~0.7V), which is conducive to crop growth and development.
Potassium humate can activate synthetases (aldolase, invertase, etc.) in plants, regulate oxidase activity, and protect auxin, which is the basic reason for improving plant stress resistance.

  1. Drought resistance mechanism
    Studies have shown that potassium humate plays an important role in improving the cell membrane permeability and protecting cell membranes.
    (1) Potassium humate increases the abscisic acid content in plants, and abscisic acid as a growth inhibitor can reduce the stomatal opening, reduce water transpiration, promote the accumulation of osmotic substances such as proline, and keep plants more water. At the same time, it promotes root development, enhances its vitality, and enables crops to absorb more water and nutrients under drought conditions; both have open source and throttling complement each other.
    (2) Improve the activity of SOD (superoxide dismutase) and CAT (catalase) to scavenge free radicals, reduce the damage of membrane lipids, delay the senescence of plants, and make the life activities of crops less affected by drought. It can be carried out more normally.

2.Cold resistance mechanism
Potassium humate can increase the content of abscisic acid in plants, and abscisic acid can increase the content of proline. Proline, as an important osmotic regulator, can stabilize the structure of biological macromolecules, so that the freezing point can be frozen and protect the plants. Cold resistance.

3.Disease resistance mechanism
Study on the mechanism of antibacterial and anti-disease of potassium humate: Potassium humate contains a variety of benzene carboxylic acids, which can produce limited immunity to certain diseases of plants: Zhang Dehe and others have been from the sulfurized coal humate potassium in Turpan, Xinjiang. 17 low molecular weight polyphenylene acids and phenolic acids were isolated and identified, and these compounds are likely to be disease-inducing agents with different induction effects.
(1) Potassium humate directly increases the soil organic matter content, provides an excellent environment for beneficial microorganisms, and the beneficial population gradually develops a dominant population, inhibits the growth of harmful bacteria, and the plant itself grows robust due to excellent soil conditions. The ability to strengthen the disease, thus greatly reducing the disease, especially the occurrence of soil-borne diseases.
(2) Potassium humate makes the number of aerobic bacteria, actinomycetes and fiber-decomposing bacteria in the soil increase more, the number of fungi is significantly reduced, the ratio of bacteria to fungi is obviously increased, and many fungi can be prevented. Disease.
(3) Potassium humate contains a phenolic type such as a carboxyl group or a phenolic hydroxyl group and a benzene carboxylic acid structure, which is the same as the active components of some phenoxycarboxylic acids and phenolic pesticides, and has a certain antibacterial and antiviral action.
