Why we choose chitosan oligosaccharide for our organic farming？

In the application of agricultural production, chitosan oligosaccharides not only make crops grow better and robust, but also has obvious effects in stress resistance and pest resistance.

Numerous studies have shown that chitosan oligosaccharides can induce broad-spectrum resistance, enhance the plant’s own defense ability, inhibit the growth of a variety of plant pathogenic microorganisms, and it is non-toxic and can be microbial degradation, and will not pollute the environment. This makes it an important role in agricultural production as a new type of green production. 
























1. Inducing the production of plant resistance proteins


Chitosan oligosaccharides and their derivatives can induce plants to produce resistance proteins against pathogens. Many studies have shown that chitooligosaccharides induce plants to produce chitinase, chitosanase and l-3-glucanase. Chitinase, chitosanase and 1,3-glucanase induced by chitosan oligosaccharides also have synergistic effects with each other, so that the antibacterial effect is more obvious.

2. Induced lignin formation

Lignin is a major component of the secondary cell wall of plant vascular tissue and is itself resistant to microbial degradation. A large number of studies have confirmed that chitosan oligosaccharides and their derivatives can induce plants to lignify around their infected sites, forming a physical barrier, preventing or delaying the growth of pathogenic bacteria and spreading to surrounding normal tissues, enhancing plant disease resistance force.

3. Changing the phenolic metabolism of plants

When people study natural antibodies, it is noted that phenols (tannin, chlorogenic acid, etc.) accumulate in large amounts at the point of infection of plants. Phenols are bactericidal substances and precursors of lignin formation. Therefore, the increase of phenols in plants can not only prevent disease, but also promote the lignification of pathogens, thus enhancing the disease resistance of plants.


The role of chitosan oligosaccharides in agriculture

Chitosan oligosaccharides have wide adaptability to plants, good affinity, no toxicity, no side effects, no harm to humans and animals, biodegradability, no soiling in the soil, slow degradation to small molecular carbohydrates, no pollution to the environment, an excellent pure natural ecological preparation.

1. Promote growth of roots

It promotes the early germination of plant seeds. The number of root hairs, fibrous roots and secondary roots is greatly increased, and the rhizosphere is developed, which will enhance the ability of plants to absorb and absorb water, enhance drought resistance, lodging resistance and enhance immunity.

2. Make the stems stronger

Studies have found that chitosan oligosaccharides have the function of regulating plant development, and are a natural plant growth regulator. They can root and promote stems, shorten stems, and grow vigorously, which is conducive to nutrients to maximize the supply of fruits.

3. Anti-Pathogens

Chitosan oligosaccharide acts as a seed coating to protect the normal development of the seed. Used for seed storage to reduce seed handling procedures. Studies have shown that chitosan oligosaccharides and their degradation products have a strong bactericidal effect on soil and seeds, and can strongly inhibit harmful fungi, hyphae such as downy mildew and cystice.

4. Soil conditioner

Using chitosan oligosaccharide as an additive, soil beneficial bacteria such as actinomycetes can be increased by 1,000 times, harmful bacteria such as Fusarium and nematodes can be significantly reduced, soil fertility can be enhanced, soil can be fundamentally improved, root knot can be cured, and soil can be improved. Higher organic content makes it easy to continuous cropping.

5. Improve Crops’ Immunity

Chitosan oligosaccharides are known as “plant vaccines.” The chitosan oligosaccharide preparation can enhance the antibacterial and antiviral ability of plants, change the growth mechanism of plants, and enhance the immune function of the regulatory system, thereby ensuring the normal growth and development of plants.

Chitosan oligosaccharides can not only help plants resist disease, but also decompose animal and plant residues and trace metal elements in the soil, thereby transforming them into plant nutrients, enhancing plant immunity and promoting plant health. It is the development direction of green agricultural production in the future.

Best Guide of Common Plant Disease in Garden

图片
For home gardeners, nothing is more frustrating than seeing their work destroyed by pests and diseases. The disease occurs when environmental conditions are suitable for the growth of pathogens on susceptible hosts. Some pathogens attack a variety of plants, while others attack only specific plants. In addition, some pathogens can attack all parts of the plant, while others attack only selected tissues. Many types of organisms cause plant infections , but the top five types of plant pathogens are fungi, water molds, bacteria, viruses, and nematodes. Adverse environmental conditions may also lead to non-infectious diseases of plants, called diseases. Adverse conditions include inappropriate soil pH, nutrient deficiency and toxicity, soil compaction, excessive water content, and herbicide destruction. Plants weakened by adverse conditions may be more vulnerable to pathogens. The following is a brief introduction of several common plant diseases, symptoms and solutions, I hop...

Best Guide- Details to Trimming Cannabis

图片
Trimming is among the most reliable means to adjust and guide the growth of a cannabis plant. If you're seeking to limit the dimension of your plant, promote side branching, delay the onset of flowering, or increase yield, trimming checks all packages. It may feel counterproductive to trim parts of your plant as it expands. However, by pruning ineffective development, you can reroute the plant's energy as well as sources into establishing high-quality flowers. While trimming is sensibly straightforward, it's likewise an ability that comes to be polished and less complicated with the method. These pruning pointers and also tricks should assist in demystifying the procedure. Why do you trim marijuana? Pruning refers to the process whereby tiny, certain sections of the plant are cut to motivate healthy growth. At its most basic level, trimming eliminates development that is harmed, ineffective, or blocking sunshine from reaching budding flowers. Pruning describes the procedure...
