As for the nitrogen fertilizer, the ammonium fertilizer should be used for rice, and the effect is better with ammonium chloride and urea. It is also effective to apply ammonium nitride fertilizer (such as ammonium bicarbonate, ammonium sulfate, ammonium chloride, urea) or nitrate nitrogen fertilizer (such as ammonium nitrate) to cereal crops such as corn and wheat. Potato and sweet potato should also use ammonium nitrogen fertilizer. Ammonium nitrate can improve the quality of tobacco. The ammonium nitrogen helps the combustion of tobacco, while the chlorine-containing fertilizer (such as ammonium chloride) reduces the flammability of tobacco and should be avoided. For acidic soils, chemically alkaline or physiologically alkaline nitrogen fertilizers should be used. In saline-alkaline soil areas, it is not advisable to purchase ammonium chloride containing more chloride ions. In alkaline soil, ammonium nitride is easy to be absorbed and utilized by crops, but care should be taken to prevent decomposition and volatilization.

About phosphate fertilizer, legume crops (soybeans, peanuts), sugar crops (beets, sugar cane), fiber crops (cotton), potato crops (potato, sweet potato), and melons and fruit trees are in high demand. Better fertilizer efficiency. In plots with a large amount of phosphate fertilizer, it is not necessary to apply it year after year to avoid waste.

Regarding potash, tobacco, potato, sweet potato, sugar beet, watermelon, fruit tree, etc. require a large amount of potassium, but these potassium crops are bogey of chlorine, and it is not suitable to apply potassium chloride. Potassium chloride is also not suitable for long-term application on saline-alkali soil. It can be used as base fertilizer and top dressing on non-chlorinated crops, but it is not suitable for seed fertilizer. Potassium sulphate is suitable for various soils and crops, and can be used as base fertilizer, seed fertilizer, top dressing and top dressing.

Regarding sulfur and sodium fertilizers, potatoes, soybeans, peanuts, and rapeseed are also sulfur-loving crops, and the effect of using ordinary calcium is better than that of "heavy calcium." Because "heavy calcium" does not contain calcium sulfate. Beets are good sodium crops, and sodium nitrate is a good fertilizer for sugar beets. Ammonium chloride avoids chlorine crops, but it is suitable for cotton, hemp and other crops, because chlorine can increase the toughness and tension of the fiber.

Natural Extracts

What is Natural Extracts?

Natural extracts are biologically active compounds or mixtures extracted from various plants and animals or microorganisms in nature. These extracts contain a wealth of chemicals, Such as alkaloids, flavonoids, saponins, polysaccharides, volatile oils, collagen, proteins, peptides, enzymes, antibodies, antibiotics, amino acids, nucleic acids, enzymes, monosaccharides, oligosaccharides, polysaccharides, glycoproteins, resins, colloids, lignin, vitamins, fats, oils, waxes, alkaloids, volatile oils, flavonoids, glycosides, phenylpropanoids, organic acids, phenols, quinones, steroids And antibiotics, etc.
Natural extracts have received attention in several fields due to their wide range of sources and potential multiple uses. They can be used in the pharmaceutical industry as ingredients in medicines or health supplements; In the cosmetic industry, as a functional or active ingredient to improve skin health; In the food industry, as an additive or flavoring agent to increase the nutritional value and taste of food; In addition, they have different applications in the fields of agriculture, environmental protection and scientific research.
Extraction methods include solvent extraction method, ultrasonic extraction method, microwave extraction method, enzyme extraction method, supercritical fluid extraction method and microwave assisted extraction method, etc. The choice of which method usually depends on the nature of the substance to be extracted and the target requirements of the final product. With the development of technology, the extraction process is continuously optimized to improve extraction efficiency, reduce environmental impact and maintain the biological activity of the extract.
