All the current jujube heads except the backbone branches and large fruiting branches were topped to control their growth, promote secondary branches, and increase the number of jujube stocks. The degree of topping can be determined according to the direction of the branches, 5-6 secondary branches can be left in the large space, and 3 to 4 secondary branches can be left in the small space to increase the number of branches of the inner bore. Results condition. At the same time, it can also wipe out the useless buds germinating on the trunk and backbone branches. If there is no use value for new shoots sprouting from jujube stocks or long branches germinating from the base of jujube heads, and other cross branches, dense branches, etc., they must be emptied when the branches have not been lignified to reduce nutrient consumption, improve light conditions, and promote Sit fruit.

what is API?
High-purity plant monomer refers to one or more single chemical components with specific biological activity or pharmacological effects extracted from plants, and its purity is usually high, meaning that the content of the component in the extract reaches a certain percentage, and the content of other impurities or irrelevant components is low.
These plant monomers are usually secondary metabolites of plants, such as flavonoids (flavonoids), alkaloids (alkaloids), terpenoids (terpenoids), phenolics (phenolics), etc., which play a variety of physiological functions in plants such as defense, signal transduction, and antioxidant. Due to their pharmacological activity, high-purity plant monomers are often used in pharmaceuticals, health products, cosmetics and other biotechnology products.
For example, Naringenin is a high-purity plant monomer extracted from citrus plants with antioxidant and anti-inflammatory activities; Corosolic acid is a high-purity active monomer extracted from loquat leaves, which is considered to be effective in treating type 2 diabetes and obesity.
Extraction and preparation of high-purity plant monomers usually require a complex separation and purification process, including extraction, column chromatography, crystallization, recrystallization and other steps to ensure the purity and activity of the final product. These processes may be required by specialized biotechnology companies.
