The efficacy and role of fulvic acid?
The efficacy and role of fulvic acid? Eight functions First, water retention The fulvic acid is a colloidal organic substance, which can loosen the soil, absorb a large amount of water, ventilate and humidify, raise cockroaches, prevent drought, and make the soil have good water, gas and heat conditions, suitable for seed germination and seedling stage. Growing. Second, improve saline land The fulvic acid has a small molecular weight and high activity, and can adsorb harmful cations in the soil, thereby reducing the concentration of salt in the soil, reducing the damage of the salt to the seeds and seedlings, and improving the saline-alkali land. Third, drought and cold resistance 1. The application of fulvic acid to plant leaves can close the stomata of plants and reduce the transpiration of plants. 2. The color of the yellow humic acid is deep, which is good for absorbing solar energy; when the fulvic acid is decomposed by the action of microorganisms, it will release heat, which can raise the ground temperature and thus play a role in resisting cold. Fourth, resistance to pests and diseases Fulvic acid can increase the activity of enzymes in plants and increase the resistance of plant organisms. Five, anti-heavy metal pollution The fulvic acid participates in the ion exchange reaction in the soil, and adsorbs and fixes the heavy metal ions in the soil to prevent them from entering the biological cycle. Sixth, improve fertilizer efficiency 1. Nitrogen fixation: Nitrogen is applied to the soil and is easily volatilized into the atmosphere or lost to the river with water and soil. The fulvic acid can adsorb nitrogen in the soil, reduce its volatilization and loss, and improve the utilization rate. 2. Solution of phosphorus: Phosphorus is applied to the soil and is easily fixed by the soil. Fulvic acid can liberate phosphorus from the soil by chelation with phosphorus, which is used for plant absorption and improves phosphorus utilization. 3. Activated potassium: Most of the potassium elements applied to the soil exist in the form of potassium salts and cannot be directly absorbed by the crops. The fulvic acid can convert the poorly soluble potassium into soluble potassium through the ion exchange function, increase the effective potassium in the soil, and improve the utilization of potassium. 4, micro-fertilizer: fulvic acid can chelate reaction with poorly soluble trace elements, and produce humic acid trace element chelate which is well absorbed by crops, which is beneficial to root and leaf surface absorption of trace elements. Seven, promote the growth and development of crops 1, fulvic acid can stimulate root growth, and ultimately the ability of crops to absorb water and nutrients is greatly enhanced 2. The stimulating effect of fulvic acid can make the above-ground vegetative growth of the plant vigorous. Expressed in plant height, stem diameter, leaf thickness, etc. 3. The fulvic acid has a good effect on tilling and reducing the openness rate, which can increase the grain weight and increase the grain yield. Eight, adjust the soil pH There are many fulvic acid functional groups, which can be combined with acid and combined with alkali to adjust the pH of the soil according to crop needs. Four major roles Improve soil Improve soil aggregate structure. The fulvic acid belongs to the humus substance, which can affect the nature of the soil, and promote the formation of a more stable agglomerate structure in the soil, so that the aggregate content of ≥0.25mm in the soil can be increased by 10-20%, and the organic matter content can be increased by 10%, so that the soil can maintain moisture. Increase ventilation, which is conducive to the growth of crops. Enhance the water retention of the soil. Fulvic acid 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. The fulvic acid inhibits the transpiration of the crop, so that the soil water consumption rate is slowed down and the soil water content is correspondingly increased. Enhance the fertility of the soil. The fulvic acid itself is an organic acid, which increases the dissolution of the mineral part of the soil, provides soil nutrients, and increases the effectiveness of nutrients through complexation. As an organic colloid, fulvic acid 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. Promote the absorption of micro-fertilizer and solve the deficiency syndrome The trace elements in the chelating agent of fulvic acid form a humic acid chelate which is highly mobile and easily absorbed by the crop, and is transmitted to the defective part of the crop to effectively solve the deficiency syndrome. The humic acid can be chelated with trace elements such as iron and zinc to form a trace element chelate of fulvic acid which is soluble and easily absorbed by plants, which effectively solves the yellowing of the leaves caused by iron deficiency. Improve crop quality The fulvic acid has the function of surfactant, can reduce the surface tension of water, and emulsify and disperse the pesticide; it can produce different degrees of hydrogen bond association or ion exchange reaction with many pesticides; make the fruit coloring and maturing in advance, similar Ethylene ripening effect, etc. Strong disease resistance 1. The fulvic acid directly increases the organic matter content of the soil, provides an excellent environment for the beneficial microorganisms, and the beneficial population gradually develops the dominant population, inhibits the growth of harmful bacteria, and the plant itself grows robust due to the excellent soil conditions, and resists disease. The ability to strengthen, thus greatly reducing the disease, especially the occurrence of soil-borne diseases. 2, fulvic acid has obvious inhibitory effect on fungi, and can prevent many diseases caused by fungi. 3. The fulvic acid contains a phenolic type such as a carboxyl group or a hydroxyl group and a benzene carboxylic acid structure, which is the same as the active ingredients of some phenoxycarboxylic acids and phenolic pesticides, and has a certain antibacterial and antiviral action. Fulvic acid is the best component of soil humus, which can not only reduce crop burden, increase soil fertility, enrich the matrix of soil bacteria, but also increase crop yield and quality, thereby helping farmers to increase production, upgrade and raise land. Long-term goal. This article URL: The efficacy and role of fulvic acid?
