Structural Formula

1. Stimulate physiological metabolism

Humic acid contains a variety of active functional genes, which can enhance the activity of agricultural catalase and polyphenol oxidase, stimulate physiological metabolism, and promote growth and development. For example, humic acid can promote early germination of seeds and has a high germination rate, especially at low temperatures. Humic acid stimulates the division and growth of extreme meristems in the root system, allowing seedlings to take root quickly. This rooting is more, the root volume increases, and the root system grows. Improve the ability of crops to absorb water and nutrients. As a result, the nutrient supply is sufficient, the crop stems are thick, the leaves are abundant, the photosynthesis is enhanced, the transfer of nutrients to the fruiting body is promoted, and the fruit is pre-colored and aged.

2. Change the characteristics of fertilizers

Humic acid contains functional groups such as carboxyl and phenolic hydroxyl groups, and has strong ion exchange and adsorption capabilities, which can reduce the loss of ammonium nitrogen to ammonium carbonate and improve the utilization rate of nitrogen fertilizers. I will. Oxidatively decomposed nitrite humic acid can inhibit enzyme activity in urine and reduce the volatilization of urea. The decayed humic acid prolongs the distance that phosphorus moves in the soil, inhibits the fixation of water-soluble phosphorus in the soil, converts fast-acting phosphorus into fast-acting phosphorus, and promotes the absorption of phosphorus by the root system. Humic acid forms highly soluble chelates of humic acid trace elements with insoluble chelates of trace elements, which are absorbed by crops, thereby promoting the root and leaf absorption of trace elements.

3. Improve soil structure

Humic acid promotes the formation of soil aggregate structure, regulates the pH value of the soil, regulates the water, fertilizer, gas, heat and other conditions of the soil, improves the soil exchange capacity, achieves acid-base balance, improves the water and fertilizer retention capacity, promotes soil microbial activity, increases the number of aerobic bacteria, actinomycetes, and cellulose-decomposing bacteria, promotes the decomposition and transformation of organic matter, promotes nutrient release, promotes crop growth and helps absorb nutrients.

4. Enhance stress resistance

Humic acid reduces the stomatal opening strength of plant leaves and reduces the transpiration of leaves. This can reduce water consumption, improve the water status of plants, ensure the normal growth and development of crops under drought conditions, and improve drought resistance. Humic acid is mainly an amphoteric colloid with high surface activity, which can inhibit fungi, enhance the cold resistance of crops, be easily absorbed by cell membranes, change the permeability of cell membranes, promote the absorption of inorganic nutrients, and promote decay and decay. It can prevent root rot and reduce pests and diseases.

5. Improve seed quality

Humic acid forms complexes or chelates with trace elements, increases the content of trace elements from roots to leaves or other parts, regulates the ratio of certain elements to trace elements, sugars, starch, proteins, and balances the synthesis of fats and various vitamins. It promotes the activity of enzymes, converts polysaccharides into soluble monosaccharides, increases the synthesis and accumulation of starch, protein and fat substances, and promotes the production of various metabolic primary products from stems, leaves or roots to fruits and seeds, making the fruits plump and thick.

Flush application: Use 10 kg of this product per 660 square meters with water and flush into the ditch, then cover with soil.

Drip irrigation: Mix 10 kg with 600-800 kg of water and drip it with drip irrigation.

Machine application: Apply 10 kg to 660 square meters and apply it to the soil with water.

1. Use it with fertilizers immediately, and do not mix it with alkaline substances.

2. It is normal to have a trace amount of grass medium in the dissolution process because it contains humic acid microorganisms.

3. Drip irrigation, flushing and machine application should be 40-50 cm away from the roots to avoid affecting crop absorption. All plants absorb nutrients and rely on fibrous roots.
