Have you heard of biostimulants? In recent years, the term has been a hot word in the agricultural market. Biostimulants have appeared in various products because people think that any substance that helps plant growth is said to be a creature. Stimulant, is this really true? So what is a biostimulant? What types? The following small series will give you a detailed introduction to biostimulants!
What is a biostimulant?
At present, the domestic understanding of biostimulants is that it is neither a pesticide nor a traditional fertilizer. However, the target of biostimulating hormone is the crop itself, which can improve the physiological and biochemical state of the plant, improve the pesticide effect and fertilizer utilization rate, improve the level of crops resisting adversity, and improve the final yield of crops and the quality of agricultural products.
The following points can help you better understand what a biostimulant is:
1. The biostimulant is naturally derived from nature and is rich in certain active substances. It can be directly applied to plants without artificial chemical synthesis. Such as the seaweed extract we are familiar with, humic acid and amino acids.
2. Unlike plant protection products, it is also different from fertilizers, which do not cause any harmful effects on humans, animals and the environment.
3. The biostimulant is a category, and the substances vary greatly from each other.
4. Biostimulating hormone does not directly act on plants, but stimulates plants to absorb and defend themselves through indirect transformation, and stimulates the development of beneficial organisms in the soil.
Types of biostimulants and their effects
Biostimulators are mainly classified into these categories, including humic acid, complex organic substances, beneficial chemical elements, inorganic salts, seaweed extracts, chitin and chitosan derivatives, anti-transpiration agents, and free amino acids.
1. Humic acid
Humic acid is a kind of natural organic polymer which is decomposed and synthesized by animals and plant residues under the action of microorganisms and geochemistry. It is widely found in soil, lakes, rivers and oceans. Including humic acid, fulvic acid and humin.
main role
Promote seed germination, root development, promote fertilizer absorption and assimilation, improve fertilizer utilization, etc., and have a significant effect on improving crop root cycle ecology, especially to improve crop drought resistance, cold resistance, and root growth.
2, amino acids
It is a general term for a class of organic compounds containing amino and carboxyl groups. It is the basic building block of biologically functional macromolecular proteins and is the basic substance that constitutes the protein required for animal and plant nutrition. It is mainly derived from industrialized hydrolysis by-products of animals, plants and microorganisms, crop residues, animal collagen and epithelial tissues.
main role
Enhances the activity of certain enzyme systems in plants and regulates certain plant growth regulators and biochemical processes in plants. They can induce plant defense responses and increase the ability of plants to tolerate a variety of abiotic stresses.
3. Seaweed extract
Seaweed is an important source of organic matter and fertilizer nutrients. They also contain a variety of inorganic and organic active compounds, including unusual and complex polysaccharides that contribute to plant growth such as kelp, fucoidan, alginates, and phytohormones. It is mainly derived from brown microalgae, red microalgae and green microalgae in the ocean.
main role
Participate in various metabolic pathways of plants such as nitrogen metabolism and antioxidant capacity. They enhance plant tolerance to abiotic stresses such as salinity, drought and extreme temperatures.
4, inorganic salts
These ionic compounds are composed of negatively charged anions and positively charged cations. It mainly includes phosphites, phosphonates, hydrogencarbonates, silicates, sulfates and nitrates.
main role
For example, phosphorus can directly act on plant metabolism, plant defense response and stomatal function. Silicon also affects many aspects of plants, increases plant resistance to fungi, corrects plant nutrient imbalances, mitigates metal toxicity, and enhances tolerance to abiotic stresses.
5, microorganisms
These include bacteria (Bacillus, Azotobacter), yeast, filamentous fungi, and microalgae. They are isolated from soil, plants, water, compost, manure, applied to the soil, and through their own metabolic activities to increase crop yield.
main role
Through nitrogen fixation and solubilization, plants can increase the absorption of micronutrients and macronutrients, and can also produce hormones such as auxin, cytokinin and the like by modifying the hormonal state of plants. It also enhances the ability of plants to withstand abiotic stresses and produces volatile organic compounds.
6, chitin and chitosan derivatives
It mainly includes chitin, chitosan and chitooligosaccharide, which is an animal polymer cellulose extracted from crab and shrimp shell by genetic engineering. Among them, chitosan oligosaccharides have lower molecular weight, good water solubility, and are more easily absorbed by plants.
main role
It can change the soil flora, promote the growth of beneficial microorganisms, and induce the disease resistance of plants, and immunize various fungi, bacteria and viruses. Regulate plant growth and improve crop quality.
7, anti-transpiration agent
It mainly includes minerals (kaolin, silicate), synthetic compounds (menthol oil, rosin diene, naphthalene), synthetic aggregates (polyacrylamide) and natural polymers (chitosan).
main role
The leaf transpiration is greatly reduced, the leaf transpiration and water loss are reduced, and the water balance in the ground and underground is temporarily maintained in the process of root damage recovery until the root system recovers the absorption capacity.
Use of biostimulants
1, pay attention to the use of time
Biostimulating hormones are not broad-spectrum, but are targeted and preventive. They are generally only suitable for biostimulating hormones. It is not necessary for all plants to be used under all conditions.
2, pay attention to use
Although biostimulators have certain magical effects, they are by no means omnipotent. They cannot completely replace fertilizers and pesticides. Not all crops are necessary under any environmental conditions. Scientific fertilization is still the premise and foundation.
3. Pay attention to field management
In addition to the use of bio-stimulant treatment, attention should also be paid to field management. Good management is the guarantee of high quality and high yield of crops. Don't forget the main body, so as not to put the cart before the horse.
The above is a complete introduction to the biostimulant, and the use and precautions for this agent are also outlined above. If you have any questions about it, please leave a message! If you have more knowledge about biostimulants, please share them!
