As a plant growth hormone, potassium fulvic acid is a very important issue in plant physiology. It is mainly manifested in:
① The breath of plants.
In plants, potassium yellow humate was originally a supplementary source of polyphenols. The quinone group contained in potassium yellow humate is an activator of oxygen, which enables plants to breathe vigorously, divide plant cells, accelerate the differentiation of plant growth points, and develop plant roots.
② Activation of enzymes.
Potassium fulvic acid plays a particularly important role in enzyme activity and metabolism. The results show that potassium yellow humate has a great influence on the activities of aldolase and invertase, can accelerate the synthesis of enzymes, accelerate the accumulation of soluble carbon water compounds in plants, and increase osmotic pressure and drought resistance.
③The reproduction and activity ability of microorganisms.
Under certain conditions, a small amount of yellow humic acid has a strong stimulating effect on crops and microorganisms. It can greatly increase the activity of fungi, bacteria and nitrogen-fixing bacteria.
④ Absorption of nutrients by plants.
Potassium fulvic acid and its derivatives can enhance the permeability of plant cell membranes and protoplasm, allowing nutrients to enter the plant body faster and get faster absorption.
1. The ratio of mineral fulvic acid to fertilizer: adding 416 kg of powder or 15 kg of liquid to urea of mineral fulvic acid can double the result with half the effort. Add 6-10 kg per ton of compound fertilizer or diammonium. Add 6060 kg of humic acid fertilizer and 6060 kg of fertilizer containing humic acid.
2. Usage and dosage: In the field, the amount of vegetables per mu is 500-800 grams, the amount of fruit trees is 2 to 3 kilograms per mu, and the amount of cotton is 1 to 1.5 kilograms per mu. The sensitivity of different crops to fulvic acid varies with different dosages. Products from different manufacturers The quality is different and the dosage is different,
