Humic acid fertilizer refers to the use of peat soil, coal slime and weathered seam coal to produce products with a lot of humic acid and nitrogen, phosphorus, potassium and some nutrients required for the growth and development of crops. , The effect in agriculture is mainly to stimulate the growth and development of crops, improve the soil layer, enhance nutrients, and enhance the theme of soil microorganisms, etc. So what is the role of humic acid fertilizer? What is the use of humic acid fertilizer?

The efficacy of humic acid fertilizer:

1. It can improve the utilization rate of base fertilizer: base fertilizer is an indispensable chemical fertilizer for plant growth. It is dominated by urea solution and carbon amine. When the urea solution and carbon amine are applied to the field, they will quickly flow out with gas and water. Only 30% of nitrogen nutrients are used for digestion and absorption. The isomerization of acid and basic functional groups such as aromatic nucleus, methyl group and carboxyl group in humic acid can react with nitrogen element to generate very stable new ion groups. Seed complex ions remain in the soil layer for a long time, and slowly dissolve and release nitrogen elements, allowing green plants to gradually digest and absorb.

2. It has the effect of improving the quality and synergy of phosphorus and potassium fertilizers: After the strong phosphorus and potassium fertilizers are applied to the soil layer, the phosphorus element will be fixed by the metal ions in the soil layer, so that the strong phosphorus can be converted into delayed-acting phosphorus or invalid phosphorus. The aromatic nucleus, methyl group, carboxyl group and other acid-base functional groups in humic acid can react with phosphorus element, making it soluble phosphorus, which improves the specificity of phosphorus element and is very easy to be digested and absorbed by green plants. After investigating the top dressing of humic acid fertilizer, the fertility of phosphorus and potassium fertilizers can be relatively increased by 5-10%.

3. It has the effect of improving the quality and synergy of potassium fertilizer: the functional group isomerization in humic acid can also digest, absorb and store calcium ions, which can not only avoid the outflow of calcium ions in the sand with water, but also avoid the fixation of potassium in the sticky soil layer. If you do not move, it can increase the potassium fertilizer usage rate by 5%.

4. It has the effect of locking water and soil: humic acid interacts with the sodium ions in the soil layer to produce a gel with flocculent sedimentation, which can combine the fine sand of the soil layer and make the particles in the soil layer become The small water conservancy projects and chemical fertilizer depots that lock water and fix soil increase the gap between the soil layers, thereby improving the ability of the soil layer to lock water and fix soil.

How to use humic acid fertilizer:

1. Soaking seeds: Soaking seeds can increase the rate of seed emergence, germinate in advance, and improve the working ability of the hair of the seedlings. Generally, the concentration value of soaking seeds is 0.005-0.05 percent, and the general soaking time is 5-10 hours, rice, cotton wool, etc. Shell seeds are 2 to 4 hours.

2. Root soaking: rice, sweet potato, etc. can be soaked with sodium humate or potassium humate aqueous solution before planting, and the concentration value is 0.01-0.05 percent. After soaking, the hair is fast and the survival rate is high.

3. Spraying: the general concentration value is 0.01-0.05 percent aqueous solution, spray 2-3 times during the flowering period of crops, and the spray volume is 50 liters of solution per 1 mu. The spraying time should be taken at 2-4 o'clock in the afternoon. good.

4. Base fertilizer: solid humic acid fertilizer (such as ammonium humate, etc.), generally 100-150Kg per 6 mu. When humic acid aqueous solution is used as base fertilizer, the concentration value is 0.05-0.1%, and the amount used per 6 mu is 0.05-0.1%. 250-400 liters of solution, can be mixed with farmyard fertilizers, can be applied in furrows or holes.

5. Fertilization: Before the seedling stage and heading stage of crops, use 250 liters of solution with a concentration of 0.01-0.1 percent per 6 mu to irrigate around the roots and stems of crops. Rice fields can be used with water injection or sprinkled on the river surface, which can improve Seedlings, vigorous seedlings, promote hair growth and other effects.
