Efficacy and application of fulvic acid on vegetables and fruit trees

The application of fulvic acid in vegetables: it is mainly to prevent the continuous pollution of vegetable soil and the infection of bacteria; it can effectively destroy the reproduction of soil bacteria; it can enhance the structure of soil aggregates, effectively promote more roots and new roots of crops, promote the development of root systems, and improve the Plant disease resistance, stimulate vegetable growth, enhance crop photosynthesis, make vegetables grow vigorously, increase yield per unit area, and increase vegetable farmers’ income. The application of fulvic acid in fruit trees: it can promote the development of the root system of fruit trees, improve the utilization rate of fertilizers, increase the rate of fruit set, enhance the color of fresh fruit, improve the quality of fruit, withstand storage after harvest, prevent root rot, and prevent diseased trees and branches of fruit trees. Has a good conditioning effect. There is a peach tree in the orchard planted by horticulturalist Gao Yingzhou of Gongyi City Horticultural Field. All the leaves are dry and dead. There is a persimmon tree with dead leaves. It is known by fruit farmers as having the magical effect of bringing back the dead. Fulvic acid is also widely used in cotton, corn, wheat, melon and fruit crops, and its effect is also more obvious than that of inorganic fertilizers. To sum up, fulvic acid has special effects such as drought resistance and moisture retention, loosening soil, increasing ground temperature, improving soil pH, and stimulating crop growth. It has attracted the attention of the agricultural sector and relevant agricultural system experts. It is listed as a green fertilizer source of fertilizer organic matter, and is welcomed by the majority of farmers.

Properties of Fulvic Acid and Basic Functions of Controlling Cotton Fusarium Wilt

Fulvic acid is a macromolecular organic compound with a small molecular weight of humic acid. It contains a variety of active functional groups, is soluble in water, acid, alkali, ethanol and acetone, is easily absorbed by plants, and has strong biological activity. It has been widely used in production. It can not only provide sufficient nutrients for cotton, but also adjust the physiological function of cotton, so that cotton can enhance its resistance to stress and effectively inhibit the occurrence of cotton fusarium wilt.

1. Fulvic acid can improve the soil. Humic acid is a colloidal organic substance. It can increase the granular structure of the soil, make the soil loose, and absorb a large amount of water. Water storage, moisture conservation, drought prevention, and good soil water, gas and heat conditions, suitable for seed germination and seedling growth. Humic acid can improve saline-alkali soil, especially fulvic acid contains more active groups, and the salt base The exchange capacity is large, which can adsorb and retain a large number of harmful cations from the soluble salt of the soil, reduce the concentration of salt in the soil, and reduce the damage of salt to seeds and seedlings. The application of fulvic acid compound fertilizer can make the emergence of saline-alkali soil. The rate and seedling rate are greatly improved, and the growth is good.

2. Fulvic acid has a stimulating effect on the growth and development of cotton. In the process of crop growth, any physiological metabolism is inseparable from the activity of enzymes. Water-soluble humic acid molecules are inhaled into the body by the roots or leaves of crops, which can regulate plants. Physiological effect, increase the activity of crop root terminal oxidase and saccharification enzyme in vivo, increase the respiration intensity of crop roots and leaves, and promote the absorption of nutrients by crops. Fulvic acid is a regulator of cotton growth. It can promote early rooting and germination of cottonseed, improve emergence rate.

Especially under low temperature conditions, the root system is elongated, resulting in a large contact area of ​​the developed root system and enhanced absorptive capacity; it can make the aerial part of the cotton grow and develop, and the cotton plant is tall, the stem is thick and dry. Substance accumulation increases; it can promote cotton leaves to increase respiration intensity, enhance photosynthesis, show that leaves are lush and green, and increase chlorophyll content. 3. Fulvic acid has a synergistic effect on chemical fertilizers, and the effective utilization rate of macro elements such as nitrogen, phosphorus and potassium is low. , so that the fulvic acid in the soil can play the role of nitrogen fixation and phosphorus release and release potassium, especially the synergistic effect of potassium fertilizer is particularly obvious. One of the pathogenic factors of cotton wilt is the lack of potassium fertilizer, and fulvic acid can reduce soil It can absorb and fix potassium, promote the release of insoluble potassium, improve the utilization rate of potassium fertilizer, and increase the amount of available potassium. Fulvic acid can chelate the insoluble trace elements in cotton fields, resulting in good solubility and easy to be used by crops. The absorbed fulvic acid trace element chelate is beneficial to the absorption of cotton roots and improves the disease resistance of cotton.
