Lignosulfonate Lignin mainly used in coal water slurry, concrete, refractory materials

Lignin is a natural organic compound that is one of the main components of plant cell walls. It has high stability and resistance to biodegradation, so it has a wide range of applications in agriculture.

Lignin can be used as a natural preservative. In agricultural production, wood, bamboo, cotton, etc., need to be treated with anti-corrosion to extend their service life. Traditional preservatives often contain harmful chemicals, which are harmful to the environment and human health. As a natural preservative, lignin not only has good anti-corrosion effect, but also is harmless to the environment and human health.

Lignin can also be used as a biomass energy source. Biomass energy is a kind of renewable energy, which can replace traditional fossil energy and reduce environmental pollution. Lignin is an important part of biomass energy, which can be converted into biodiesel, bioethanol and other fuels through biomass energy technology, and used in agricultural machinery, power generation and other aspects.

Lignin can also be used as a soil amendment. Soil is the basis of agricultural production, and the quality of soil directly affects the yield and quality of crops. Lignin can be decomposed by microorganisms to release organic acids, nitrogen, phosphorus and other nutrients, promote the growth and reproduction of soil microorganisms, improve soil structure and fertility, and improve crop yield and quality.

Lignin can also be used as a biological pesticide. Traditional chemical pesticides often cause certain harm to the environment and human health, while biopesticides are a more environmentally friendly and safe pesticide. Lignin can be decomposed by microorganisms to produce some substances with bactericidal, insecticidal and acaricidal effects, which are used to prevent and control crop diseases and pests to achieve the purpose of green prevention and control.

Lignin can also be used as a food additive. Lignin can be extracted by chemical or biological methods with some antioxidant, antibacterial, anti-inflammatory and other effects of substances, used in food processing, can extend the shelf life of food, improve the quality of food and nutritional value.

Lignin has a wide range of applications in agriculture, can be used as preservatives, biomass energy, soil amendments, biological pesticides and food additives. With people's attention to environmental protection and health, the application prospect of lignin will be more and more broad.
