Application method and notice of Fulvic acid fertilizer
1. The role of fulvic acid
Fulvic acid is often used in agriculture. Fulvic acid's "five functions" in agriculture (improving soil, increasing fertilizer efficiency, stimulating growth, enhancing stress resistance and improving quality) have been guiding the application and progress of humic acid in agriculture. Fulvic acid is a humic acid product with a wide range of applications and high economic benefits. So far, it still has a large market and competitive advantage in plant growth agents, anti-stress agents, fluid fertilizers, pharmaceutical preparations, and cosmetics. Fulvic acid's "four-agent functions" in agriculture (drought-resistant agents, growth regulators, pesticide slow-release synergists and chemical element complexing agents) are classic and unique as a drought-resistant agent.
2. Development prospects of fulvic acid
(1). The whole process and quality control technology system of China's green food have reached the food quality and safety standards of developed countries such as the European Union, the United States, and Japan, and has been in line with international standards. However, the fundamental problem of how to produce green and safe food lies in how to overcome and Preventing soil pollution From the perspective of fertilization, we must adhere to the combination of organic and inorganic fertilizers. The use of humic acid fertilizers is the only option. The combination of humic acid and chemical fertilizers can achieve an integrated effect of 1+1>2.
(2). A large number of studies have shown that humic acid is a good friend of inorganic fertilizers, a slow-release agent and stabilizer of nitrogen fertilizers, a synergist of phosphate fertilizers, a protective agent of potash fertilizers, a regulator and chelating agent of middle and trace elements. Acid has a significant synergistic effect on chemical fertilizers, and it is currently the Mount Everest among chemical fertilizers in the world.
(3). The future development direction of humic acid fertilizers is: intelligent, specialized, compound, long-acting, granulated and regionalized fertilizer for fools. It can be seen that the development and application of humic acid fertilizers have broad prospects. Only the use of humic acid fertilizers can realize the greening of agricultural fertilizers and promote and promote the production and development of green agricultural products.
3. When is fulvic acid used?
(1). If the soil is acidified or in saline-alkali land, fulvic acid can be used to adjust the acid-base to create a good growth environment for crop roots.
(2). After excessive chemical fertilizer, the soil will be salinized, compacted, and lack of organic matter. fulvic acid can be used to reduce soil conductivity and reduce free salt in the soil.
(3). The effect is not ideal after using biological inoculants. Biological bacteria can be combined with fulvic acid. fulvic acid can provide carbon source for biological bacteria, increase the reproduction speed and number of beneficial bacteria, and make biological inoculants more effective.
(4). The ground temperature is low, especially in winter, because potassium nitrate will reduce the water temperature after being dissolved in water. Adding fulvic acid to the fertilizer can alleviate the adverse effects of low temperature on the root system. In addition, the color of the ground surface is darker after fulvic acid is applied, which makes it easier to absorb sunlight, which is beneficial to increase the ground temperature.
(5). Before the dry season and rainy season, the use of fulvic acid will reduce the field losses after drought and flood to a certain extent.
(6). If the roots are underdeveloped and premature senescence caused by any of the above reasons, fulvic acid acid should be used. fulvic acid can promote the growth of crop capillary roots.
(7). All crops that need to pursue color and surface smoothness must use fulvic acid, because it can promote the synthesis of wax, cutin and lignin on the surface of the crop.
(8). For crops that need swelling,fulvic acid must be used. fulvic acid can increase the number of cells in the swollen part and increase the cell volume.
(9). For crops that grow weak and need rapid recovery, fulvic acid must be used.
4. How to use fulvic acid?
(1). Soaking the seeds in a ratio of 1:40 with fulvic acid and water for 2 minutes can increase the germination rate of the seeds and make the seeds germinate.
(2). Soak the seedlings in a ratio of 1:40 with fulvic acid and water for 2 minutes and then plant them to promote the growth of the roots of the seedlings and promote the development of the seedlings
(3). In the later period of management, the fulvic acid and water should be flushed at the water outlet at the ratio of 1:400. Fulvic acid is very soluble in water.
The above several cases of using humic acid are not wrong, but many people do not feel good after using it. Why? Here are a few common misunderstandings for everyone.
1. Humic acid should not be used as many times as possible at a time, but a small amount for multiple times. Use 5 kg at a time, not as good as 1 kg at a time, 4 times in a row.
2. Don't just use flushing, the combination of flushing and spraying will make the synergy effect more obvious.
3. Not every crop has visible effects on fulvic acid. When using, you must know the enthusiasm of crop response in advance:
(1) Humic acid has the most obvious effect on root crops, so radish, potatoes, sweet potatoes, etc. should be used in promotion experiments.
(2) Melons with large leaves, wheat, rice, etc.
(3) The crops with insignificant effects include oilseed crops such as rape and castor. Although the actual effects are there, such as the speed of root development, root-shoot ratio, etc., the data can only be detected by scientific methods, which is difficult to identify with the naked eye.
4.The soil itself contains a lot of humus. Under very good conditions, the effect of applying fulvic acid is not obvious. Therefore,fulvic acid can be used to "send charcoal in the snow" instead of "icing on the cake." Using 1 kg for the problematic soil is better than using 5 kg for normal soil.
