Wheat heading to filling stage. An acre of wheat consumes about 10,000 kilograms of water on average, and consumes 300,000 kilograms in 30 days. Three hundred million kilograms of wheat consumes 30 trillion kilograms or 15 billion tons of water. Many people believe that the water in the wheat field is mainly due to the transpiration of sunshine. In fact, more than 90% of the water is steamed through the leaves. Agricultural chemists in various countries have tried to find a chemical to reduce the transpiration of the foliage.

However, some of the found agents are expensive, have a short duration of action, and some have disadvantages such as pollution and poor photosynthesis, so they are not practical.
It is the Chinese scientists who first discovered that the natural fulvic acid has anti-transpiration effect and made a report at the world conference held in Australia, which has attracted the attention of all countries in the world. fulvic acid is different from the above-mentioned chemical reagents, and the price is low. The action time can reach ten to fifteen days, and it is pollution-free and does not hinder normal photosynthesis. fulvic acid reduces transpiration by 10-15% in ten to fifteen days. Don’t underestimate this number. It says that 100 million mu of wheat will be transpiration of 15 billion tons of water a month, and a 10% reduction is 1.5 billion tons. This is of great significance for wheat to fight drought and harvest.

What is the reason that fulvic acid can reduce water transpiration?
We observed using a high-resolution electron microscope that the water is transpiration from the small pores of the leaf surface. The fulvic acid can reduce the opening of the pores of the leaves, reduce the transpiration of water, and mobilize the absorption of potassium ions by plants. Promote metabolism, promote respiratory intensity, photosynthesis intensity, promote plant enzyme activity, improve crop drought resistance, and thus improve water-saving capacity, and plants’ ability to resist drought, cold, and pests and diseases will increase. When wheat is grouted, it is most afraid of dry hot air. It can be seen that the transpiration of 10,000 jin of water in the first part of the article is normal. When the dry hot air comes, the temperature is high, the air is very dry, and there is wind. The transpiration will be greatly enhanced. The water absorbed by the roots is far from being supplied. In severe cases, the wheat will die and die, not to mention the reduction in production. If you pay attention to the weather forecast, spraying the fulvic acid one to two days before the onset of dry hot air can effectively resist heat and drought. Similarly, spraying fulvic acid one to two days before the cold current can greatly reduce the impact of cold current on crops.

In all the living things in this carbon planet, carbon is the basic element, and the organic matter formed by carbon as the framework is the basic material of life.

 At present, China’s cultivated land faces severe challenges, with poor depletion (slab formation, desertification, salinization), and low- and medium-yield fields accounting for 74%, resulting in widespread weak roots, sub-health, and frequent diseases.

Due to the indifference to carbon and the fact that farmers do not care about arable land, do not cultivate fertility, and rely on chemical fertilizers and pesticides, the “chemical farming” model has been popularized in China’s hundreds of millions of acres of cultivated land. We have carried out carbon plundering of cultivated soil for 30 years. .

 Plant carbon nutrients come not only from the “channel” of carbon dioxide photosynthetic transformation by chlorophyll, but also from another pathway that roots absorb from the soil. Leaf absorption and transformation is the main force of carbon accumulation, and soil carbon nutrient can produce serial promotion and energy transfer to soil fertility (ie, physical fertility, chemical fertility, and biological fertility), which promotes secondary processing of soil to fertilizer, thus directly affecting Photosynthetic conversion efficiency of the leaf suction channel.

Soil organic matter is a natural “carbon pool”, but the carbon in organic matter cannot be directly absorbed by plants. Only by biochemical action, the small molecule water-soluble organic carbon is gradually decomposed, which is the true plant carbon nutrient. The carbon nutrient content of the fertilizer determines the organic fertilizer efficiency of the fertilizer. Carbon nutrients are the basic substances for the three fertility of NPK. Soil-poor organic carbon microbes lose energy and cannot reproduce, which is the root cause of soil compaction and the main reason for low fertilizer utilization. Agriculture needs to reach a new level, food must be safe, and the biggest room for improvement is carbon supplementation.

Humic acid is an “ecological factor” in nature. It is the “grand baby” of the soil, the “white blood cell” of the water body, the “safeguard” for purifying the environment, and the “buffer” of the carbon cycle. Over the past 18 years, the Association has been committed to the development of green and low-carbon, and has always made a positive contribution to climate change mitigation.

Potassium humate contains a variety of functional groups, and the activated potassium humate becomes a highly effective biologically active substance, which has a stimulating effect on crop growth and physiological metabolism in the body. This characteristic is not available in general fertilizers, and activated potassium humate.

Efficient bioactive substances are soaked, soaked, rooted, sprayed, watered, and made into a base at a certain concentration, which has obvious stimulating effects on various crops. The comprehensive performance is in the promotion of root development, and has a good influence on crop yield and quality factors.

The role of potassium humate in crop development.

(1) Early germination, high emergence rate
The application of potassium humate can accelerate seed germination and increase the emergence rate, especially in early spring and low temperature (generally germination 1 to 3 days earlier, and the emergence rate is increased by 10 to 30%).
(2) The root system is developed and the absorption is strong
Potassium humate has a special promoting effect on the root development of crops. Many agricultural scientists call humic acid potassium as the “root fertilizer”. The effect on roots is mainly to stimulate the division and growth of root meristem cells and make seedlings. The hair roots are fast, the secondary roots are increased, the roots are increased, and the roots are elongated, which ultimately leads to a greatly enhanced ability of the crop to absorb water and nutrients.
(3) Effects on the growth of above-ground vegetative bodies
On the basis of sufficient nutrient supply, the stimulation of potassium humate can make the above-ground vegetative growth of the plant strong, which is manifested in plant height, stem diameter, number of leaves and accumulation of dry matter.
(4) Impact on production and composition factors
Potassium humate has different yield and composition factors for different crops. It has an effect on increasing the yield of grain crops, spikes, grains and 1000-grain weight. In the early stage, it has good effects on tillering and reducing the emptying rate.

Potassium humate enhances drought, cold and disease resistance of crops.

(1) Improve crop drought resistance
The application of potassium humate can reduce the stomatal opening of plant leaves.
The water condition in the plant is improved, the water content of the leaves is increased, and the foundation is laid for the ear and the seed. The application of potassium humate can also increase the content of chlorophyll and the normal progress of photosynthesis, for the accumulation of matter and 1000-grain weight. The improvement is very important.

(2) Enhance the cold resistance of crops
The application of potassium humate has obvious effects on early spring breeding in the south and cold resistance in northern wheat. In the south of China, early rice cultivation, often encounters low temperature and rainy weather, often occurs in dead seedlings and rotten seedlings. After application of potassium humate, the ground temperature is improved and the quality of seedlings is generally improved. Winter wheat in most parts of northern China, due to frequent “cold spring”, wheat seedlings are generally affected by winter, the application of potassium humate, effectively improve the cold resistance of wheat, and reduce the freezing damage to varying degrees.

(3) Control of plant diseases and insect pests and immunity
Potassium humate can effectively control underground pests and diseases and plant diseases and pathogens. Potassium humate has obvious effects on the control of fruit tree rot, leaflet, yellow leaf disease, downy mildew of cucumber, anthracnose of pepper, virus disease, etc., and potassium humate is applied without any pesticide. Cucumber did not have any major pests and diseases from beginning to end.

Humic acid is a kind of macromolecular compound with relatively complex composition. According to its solubility in different solvents, it is divided into three components, namely fulvic acid, brown humic acid and black humic acid. Humic acid is widely found in lignite, weathered coal and peat in the natural world, with a content of 30% to 70%. In the 1970s, China had set off a wave of research and application of humic substances, mainly to solve the agricultural production of fertilizer at that time. shortage.

The biological activity and special structural properties of humic acid play a peculiar role in plant growth. The organic acid substance provided by humic acid in natural coal is called MFA, and the humic acid substance produced by our first biochemical method is called BF (Biotechnolosy Fulvic scicl). This environmentally friendly green technology provides a greater platform for the application and development of humic acid products. At present, humic acid have been used in agriculture, forestry, medical and health, environmental protection, pesticides, fertilizers and other industries. In particular, people’s awareness of environmental protection, the prevalence of green health food, then solve this problem and provide these edible substances, humic acid will play an important and unique role, thus, humic acid will have a broader market space, It will also promote the faster development of this product and industry.

Principle of biological activity of humic acid

The main elemental composition of humic acid is carbon, hydrogen, oxygen, nitrogen, sulfur, and is a polycondensate of a polyvalent phenolic aromatic compound and a nitrogen compound. The molecular weight distribution is wide, the molecular weight of small molecules is tens of thousands, and the molecular weight of macromolecules is tens of thousands to millions.

The structure is also quite complicated, and contains various functional groups such as phenolic hydroxyl group, hydroxyl group, alcoholic hydroxyl group, hydrazine hydroxyl group, enol group, sulfonic acid group, amine group, free sulfhydryl group, sulfhydryl group, decyloxy group, methoxy group and the like. . Each composition is entangled by chemical and physical interactions such as bonding, hydrogen bonding, and adsorption. Due to the presence of these reactive groups, the acidity, hydrophilicity, ion exchangeability, complexation and high adsorption capacity, buffering and catalytic ability of humic acid are determined. The addition of humic acid to the feed can effectively adsorb various toxic and harmful substances produced by the feed, and can also absorb toxic substances produced by digestion and metabolism during digestion and metabolism. Such as: amines, hydrogen sulfide and other substances, maintaining the normal microflora of the intestines.

Humic acid is added to the feed and can also act as a drug, which has a significant therapeutic effect on intestinal ulcers and gastritis. Because humic acid contains small molecules of fulvic acid, it can adhere to the surface of the ulcer, which can quickly stop bleeding and facilitate rapid healing of the tissue. Humic acid has an immune-enhancing effect on animals, and promotes antigenic substance uptake, cellular immunity and humoral immunity in the immune process. Humic acid contains sulfhydryl groups to participate in the body’s redox reaction, maintain strong metabolism, and promote cell proliferation.

Humic acid can also act on the autonomic nervous system, inhibiting the excitation of the sympathetic nerves, making the animals quiet and reducing consumption. Because humic acid is an organic acid, it can regulate the pH value of digestive tract, promote the secretion of digestive enzymes in young animals, activate the activity of various enzymes in the body, change the permeability of cell membrane, improve the absorption of feed nutrients, and improve the feed. Utilization, promote growth and development. For biochemical fulvic acid, it not only contains humic acid, but also contains a certain amount of nucleic acid, amino acid, VB, VC, inositol, polysaccharide, in addition to having strong biological activity, it is also an important nutrient for animals.

In summary, according to clinical evidence, humic acid has hemostasis, anti-inflammatory, analgesic, astringent, adsorption, anti-allergic, secretory secretion, regulation of gastrointestinal function, improve immunity and enhance animal disease resistance. At present, some feed manufacturers, in order to cater to the consumer psychology of the farmers, improve the growth of animals, the pursuit of feed effects, the addition of a large number of antibiotics in the feed, due to the residues of antibiotics, directly affect people’s health. As a green product, humic acid can be added to the feed to replace antibiotics. Scientific research in recent years has shown that humic acid, as a new type of feed additive, has a peculiar effect and plays a very important role in aquaculture, and will certainly promote the development of the feed industry.

Prospects for the development of humic acid

Humic acid is used in aquaculture. It is still rare in domestic reports. As a natural active substance, it can be used as a disease prevention agent within a certain range. The development of humic acid has broad market prospects. Problems in the humic acid industry: If the scale of production is small, the technology is relatively backward, the quality is unstable, the technical strength of each enterprise is weak, and the development and application research are not enough, thus restricting the development of this industry. The peculiar effect of humic acid is not well understood, and further research is needed, as well as increasing the application space and application value of humic acid.

Sodium humate is black and bright, with a bright luster of amorphous particles. It is non-toxic, odorless, non-corrosive and extremely watery. Mainly used for convergence, hemostasis, and diarrhea. For vomiting blood, blood in the stool, diarrhea, vomiting, abdominal pain, diarrhea in children, spleen diarrhea, long time.

Sodium humate is chemically refined from high-quality low-calcium and low-magnesium weathered coal containing natural humic acid. It is a multifunctional polymer compound containing hydroxyl, sulfhydryl, carboxyl and other reactive groups. The internal surface area has strong adsorption, exchange, complexation, and chelation ability.

Sodium humate has been applied and recognized in many fields of the national economy by the Chinese Academy of Sciences, the Ministry of Chemical Industry, the Ministry of Coal, the Ministry of Petroleum, the Ministry of Railways and related research and production departments of various provinces and cities. Especially as ceramic additive, debonding agent, drilling mud conditioner, industrial water stabilizer, cement water reducing agent, boiler descaling agent, ore flotation agent, waste gas treatment agent, water coal slurry admixture, briquette bonding Agents, battery cathode plate expanders, etc., show a strong vitality, achieved significant economic effects, and the prospects are very broad.

Secondly, sodium humate as a compound fertilizer additive in agriculture can change the soil structure and play a role in disease prevention, disease resistance, yield increase and income increase. Sodium humate has been used as a feed additive in poultry farming and as a synergist in aquaculture, and has achieved significant economic benefits.

Fulvic acid is the smallest and most active component of humic acid. It is the essence of the active ingredients of humic acid. In the practical application of agricultural production, the stability of fulvic acid is the best.

Fulvic acid is the best core component of soil humus. Is that the molecular weight generated by decomposition and decomposition of organic matter is small, Fully water soluble organic aromatics,
Is the best humic acid in the soil,It is the core material that forms the structure of soil aggregates.

Advantages of fulvic acid


The fulvic acid contains functional groups such as carboxyl group and phenolic hydroxyl group, which has strong complexation, chelation and surface adsorption ability, can reduce the loss of ammonium nitrogen, increase the moving distance of phosphorus in the soil, and inhibit the fixation of water-soluble phosphorus in the soil. Ineffective phosphorus is converted into effective phosphorus, which promotes the absorption of phosphorus by roots; fulvic acid can absorb and store potassium ions, and the effective potassium content is especially effective for potassium fertilizer.

The fulvic acid can increase the utilization rate of nitrogen, phosphorus and potassium nutrients in the fertilizer by more than 20%.

The synergistic effect of fulvic acid on nitrogen fertilizer The active groups of fulvic acid (including carboxyl groups, hydroxyl groups and certain groups containing P, O, N, S) are generally electron donors, which are easily associated with many electron acceptors. (Multivalent metal ions, organic groups or ions) constitute a coordination compound called a complex or a chelate. For example, fulvic acid-urea, etc., is actually a complex (chelating) substance, which can reduce the loss of ammonium nitrogen and increase the utilization rate of nitrogen fertilizer. Oxidatively degraded nitroxanthohumic acid can inhibit urease activity and reduce urea volatilization.

Adding fulvic acid to ammonium bicarbonate can reduce the nitrogen volatilization rate of ammonium bicarbonate from 13.1% to 2.04% in 6 days. In the farmland test, the effect of ammonium bicarbonate was maintained for more than 20 days, and the ammonium fulvic acid could reach more than 60 days. The addition of fulvic acid, especially nitroxanthate, to urea can form a urea complex, which slows the decomposition of urea, prolongs the fertilizer efficiency, reduces the loss, and increases the utilization rate of urea by 30% and the aftereffect by more than 15%. As a result of measuring the nitrogen use efficiency, the utilization rate of fulvic acid was increased from 30.1% to 34.1%, and the nitrogen uptake was increased by 10%.

The effect of fulvic acid combined with nitrogen on plant growth and development is very obvious. When nitrogen and fulvic acid are sufficient, plants can synthesize more protein, promote cell division and growth, so the plant leaf area grows faster, and more leaf area can be used for photosynthesis. It has obvious effects on promoting plant growth and health. Often, after application, the leaf color turns green quickly and the amount of growth increases.

The synergistic effect of fulvic acid on phosphate fertilizer: Degraded fulvic acid can increase the distance of phosphorus movement in the soil, inhibit the fixation of water-soluble phosphorus in the soil, convert the ineffective phosphorus into effective phosphorus, and promote the absorption of phosphorus by roots. Use fulvic acid to protect water-soluble phosphate fertilizer or phosphorus-based compound fertilizer to reduce phosphorus fixation; promote phosphorus absorption and increase phosphorus fertilizer utilization rate.

The fertilizer efficiency test showed that adding 10-20% of fulvic acid to calcium, heavy calcium or ammonium phosphate could increase the fertilizer efficiency by 10-20% and the phosphorus uptake by 28~39%. The radioactive phosphorus tracer test measures the utilization rate of phosphate fertilizer. After adding fulvic acid, the utilization rate of phosphate fertilizer increased from 15.4% to 19.3%, that is, the utilization rate of phosphate fertilizer increased by a quarter.
The fulvic acid and phosphate fertilizer participate in photosynthesis, respiration, energy storage and transmission, cell division, cell enlargement and other processes in plants.

Synergistic effect on potassium fertilizer: The acidic functional group of fulvic acid can absorb and store potassium ions, and reduce the amount of potassium lost with water in sandy soil and leached soil. The fulvic acid prevents the fixation of potassium in sticky soils and increases the amount of exchangeable potassium.

fulvic acid has a dissolution effect on the potassium-containing minerals, slowly increasing the release of potassium and increasing the content of available potassium in the soil. Fulvic acid can also use its biological activity to stimulate and regulate the physiological metabolism of crops, increasing the potassium uptake by more than 30%.

The combination of fulvic acid and potassium promotes photosynthesis, can significantly increase the absorption and utilization of nitrogen by plants, and is quickly converted into protein, and can also promote plant economic water.

Promote the absorption of micro-fertilizer and effectively solve the deficiency syndrome: the trace elements in the chelating agent of fulvic acid form a humic acid chelate compound which is highly mobile and easily absorbed by crops, and is transmitted to the defective part of the crop to effectively solve the deficiency syndrome.

In addition to a large number of elements such as nitrogen, phosphorus and potassium, crop growth and development also requires trace elements such as iron, boron, manganese, zinc, molybdenum and copper. They are components of various enzymes in the crops and promote the normal growth and development of crops. Increasing disease resistance, increasing yield and improving quality all have important implications. Most of the trace elements in the soil are in an ineffective state that plants are difficult to absorb, and the application of trace element fertilizers to the soil is also easily fixed by the soil.

According to the research, decoctantic acid can react with trace elements such as iron and zinc to form a sulphate trace element chelate compound with good solubility and easy to be absorbed by plants, such as fulvic acid-Zn and fulvic acid-Mn. , fulvic acid-Fe, etc., is conducive to the absorption of roots or leaves, and can promote the trace elements from the roots to the upper part of the ground.

The experiment showed that the amount of iron fulvic acid entering the roots from the roots was 32% more than that of ferrous sulfate, and the number of movements in the leaves was twice that of ferrous sulfate, which increased the chlorophyll content by 15 to 45%, effectively solving the problem caused by iron deficiency. Yellowing of the leaves.

Fulvic acid, important for agriculture

As a plant growth regulator, fulvic acid is the best component of soil humus, not only reducing crop burden, increasing soil fertility, enriching the matrix of soil bacteria, but also improving crop yield and quality to help agriculture Achieve long-term development goals of increasing production, upgrading, and raising land. Thereby solving the quality problem of crops. ”
