Fulvic acid is the component with the smallest molecular weight and the largest activity in humic acid. It is a gray black powder dissolved in water. As a plant growth regulator, fulvic acid can promote plant growth, play an important role in combating drought, improve plant stress resistance, increase yield and improve quality. The main application objects are wheat, corn, sweet potato, millet, rice, cotton, peanut, rape, tobacco, sericulture, melons and fruits, vegetables, etc. In the practical application of agricultural production, fulvic acid has the most stable and best effect.
Fulvic acid has two effects on agriculture, direct and indirect.
Direct effect: Promote plant growth and increase crop yield.
Indirect action: Divided into physical action, chemical action and biological action.
Physical action: ① Improve soil structure. ② Prevent soil cracking and erosion. ③ Increase soil water holding capacity and improve cold resistance. ④ Darken the soil color, which is conducive to solar energy absorption.
Chemical action: ① Adjust soil pH value. ② Increase soil buffer capacity. ③ Improve and optimize the absorption of nutrients and water by plants. ④ It is rich in organic matter and minerals necessary for plant growth. ⑤ Improve the solubility of organic fertilizer and reduce the loss of fertilizer. ⑥ So that all kinds of nutrient elements can be easily absorbed by plants.
It can strengthen the absorption of nitrogen by plants, reduce the fixation of phosphorus, store nitrogen, phosphorus, potassium and other elements deep into the soil in the protective box in the soil, accelerate the process of nutrient elements entering the plant body and improve the application effect of inorganic fertilizer. Therefore, fulvic acid is the “reserve” of plant nutrients and physiologically active substances.
Biological action: ① Stimulate the growth and reproduction of beneficial microorganisms in soil. ② Improve the natural disease and insect resistance of plants. After using biological fulvic acid liquid, soil fertility was significantly improved, and plant growth recovered well.
In order to achieve green agriculture, bio fulvic acid is an easily soluble, water-soluble, dark black liquid, which is highly soluble in water. It has strong activity and is beneficial to the growth and absorption of crops. It combines the nutrients needed by crops, joins biological organic matter and various minerals, has the function of drought and cold resistance, repair damaged plant tissues, and improve the autoantibodies of crops. The use of biological fulvic acid liquid can improve the quality and yield of crops.
Efficacy of fulvic acid liquid:
Fulvic acid liquid can promote cell growth, activate plant ducts, rejuvenate weak seedlings, elongate taproots, increase fibrous roots, developed roots, deep roots and luxuriant leaves, and improve the ability of lodging resistance, drought resistance and cold resistance.
Fulvic acid liquid can repair cells, stimulate vertical and horizontal growth of plants, promote flower bud differentiation, strengthen plants, supplement nutrients, strengthen seedlings and leaves, reduce element deficiency, improve immunity, repair damaged tissues and quickly restore growth.
Fulvic acid liquid can improve the synthesis of sugar, vitamins and proteins, increase hormonal power, balance the proportion of male and female flowers, promote the vertical and horizontal growth of fruit, improve the toughness of fruit stalk, reduce fruit falling and cracking, and reduce abnormal fruit. The fruit has beautiful appearance, uniform color, crisp and sweet juice, improve quality and restore natural flavor.
Fulvic acid liquid can effectively alleviate the harm of medicine and fertilizer, activate the cell cycle growth system, improve soil acidification and hardening, enhance soil permeability, moisturize and lock fertilizer, cultivate soil fertility, delay the premature aging of crops, improve the growth environment and reduce the harm of crop continuous cropping.
