Application of Chitin in Agricultural Development

The research and development and application of chitin have achieved considerable success. Because of its wide range of functions and applications, it is hailed as "the last gift God gave to mankind" and "the savior of the earth's environmental pollution."

In nature, when insects stay on plants, chitin on the insect's feet stimulates plants to secrete chitosan-degrading enzymes. Plants decompose and absorb this chitosan, which not only activates cells, but also grows stems and leaves. And it can make the flowers more beautiful and the fruit more fruitful. A few decades ago, aphids, bees, etc. were common table dishes, and humans naturally ingested chitin.

Now, with the development of human industry, the pollution of the global environment and the changes in the agricultural ecological structure have caused a large number of insects to be reduced, so the chances of being able to eat chitin are becoming less and less. It can be said that modernity is "the era of lack of chitin", and thus the importance of chitin. But now, scientists have done a lot of research and development work on chitin, especially in agriculture, and have begun to use a wide range of applications.

Now people have begun to advocate natural beauty, green food, environmentally friendly functional products, and ecological agriculture. To this end, scientists have done their best in this regard, and have successfully developed an emerging high-tech product - chitin. The research and development and application of chitin have achieved considerable success. Because of its wide range of functions and applications, it is hailed as "the last gift God gave to mankind" and "the savior of the earth's environmental pollution."

Studies have confirmed that chitin, as a plant function regulator, can regulate the closure and opening of plant genes, and induce plants to secrete resistant enzymes. This not only promotes the activation of plant cells, stimulates plant growth, but also increases the self-defense ability against pests and diseases. In particular, chitosan oligosaccharides having a higher degree of polymerization have a function of inhibiting the growth and reproduction of pathogenic bacteria, and thus it is also called a novel plant resistance inducer.

Chitin is prepared as a water-soluble preparation using modern biotechnology. Using it to soak seeds or foliar sprays, it induces the initiation of plant resistance-related protein genes, allowing plants to produce resistance-related proteins.

The chitin preparation can cause the plant to produce a systemic resistant body, ie, a part that produces resistance, which can induce resistance to the entire plant. Chitin is a nutrient for soil beneficial bacteria such as actinomycetes, which promotes the reproduction of actinomycetes and induces actinomycetes to produce chitinase, thereby inhibiting harmful bacteria in the soil: at the same time, it improves soil ecology due to the proliferation of actinomycetes. Environmental and plant quality to achieve the purpose of increasing production.

Chitin is a film-forming substance, which is coated with seeds or sprayed on the foliage of plants to have the function of venting and retaining water, which can promote the photosynthesis of plants and the absorption of normal nutrients. Spraying in the early stage of plant harvest can greatly increase plant resistance and prolong the shelf life of seeds, vegetables and fruits.

In agriculture, the use of chitin as a raw material, using modern biotechnology to decompose, extracting and adding a variety of trace elements (required for plant growth), has been praised as a good result in agriculture. "Plant vaccine." The application of chitin in agricultural production not only has a stable and significant income-increasing effect, but also has good growth, robust plants, enhanced photosynthesis, and also has obvious effects in stress resistance and pest resistance. In addition, the improvement of crop quality has a greater significance for improving the nutritional value and economic value of food. The main functions are as follows:

1. 1. It has strong practicability. Chitin has wide adaptability to plants, good affinity, no toxicity and no side effects, and is harmless to humans and animals. It is an excellent pure natural ecological preparation.
2. 2. The root system is developed, which can promote the early germination of plant seeds, the root system is developed, and the number of root hairs, roots and secondary roots is greatly increased. With the root of the plant, the rhizosphere is developed, which will enhance the ability of plants to absorb water and absorb water, enhance the ability of plants to resist drought and lodging, and enhance immunity to achieve more robust results.
3. 3. Activate rhizosphere state, chitin can fully activate the rhizosphere state, enzymatically resolve nutrient molecules, and rapidly form soil solution, so that nitrogen, phosphorus, potassium and other nutrients can be fully and effectively absorbed by plants.
4. 4, thick and thick, the study found that chitin has the function of regulating plant development, so that the stem is shortened, thick and strong, and is conducive to the maximum supply of nutrients, in which trace elements are easily absorbed by the fruit under the stimulation of chitin. , thereby stimulating the formation of proteins and amino acids, and fundamentally improving quality.
5. 5, strong bactericidal ability, chitin can replace seed coating agent, protect the normal development of seeds, use seed storage, reduce seed treatment procedures, and economical. Studies have shown that chitin and its degradation products have a strong bactericidal effect on soil and seeds, and can strongly inhibit harmful fungal hyphae such as downy mildew and cystice.
6. 6. Improve soil and use chitin as an additive to increase soil beneficial bacteria such as actinomycetes by 1000 times, harmful bacteria such as Fusarium and nematodes, and enhance soil fertility, fundamentally improve soil and cure knots. . Improve soil organic matter content and facilitate continuous cropping.
7. 7, improve crop quality, increase yield, chitin can increase crop chlorophyll content and nitrate reductase, in addition to increased sugar content, mouthfeel. At the same time, the reduction of pesticide residues (below international standards) can be exported through the green channel.
8. 8. Improve fertilizer efficiency, chitin has strong film-forming function, can delay the release of fertilizer elements, reduce the loss of nutrients and greatly improve fertilizer efficiency, thus fundamentally solving the waste of fertilizer, saving money, protecting the environment and benefiting human health.
9. 9. Enhance immunity. Chitin is known as “plant vaccine” in Korea and Japan. It can be seen that it plays a role in crops. Chitin preparation can enhance the antibacterial and antiviral ability of plants. Change the mechanism of plant growth, enhance the regulation system immunity, thus ensuring the normal growth and development of plants.

With the continuous development and utilization of chitin in the agricultural field, products synthesized from chitin and other corresponding raw materials are also being continuously introduced. For example: chitin slow release fertilizer, chitin fertilizer, chitin water retention fertilizer, chitin intelligent fertilizer.

Therefore, chitin plays an invaluable role in agricultural production, and it also provides an effective method for reducing pollution and developing green ecological agriculture. In addition, chitin and its decomposition products have good adsorption properties, can effectively concentrate heavy metals and their difficult to decompose substances, and can effectively degrade pesticides and other organic substances. From this point of view, chitin is an excellent promising scavenger.
