Yes. In winter wheat cultivation, nitrogen fertilizer is generally divided into two applications, the first is the bottom fertilizer before sowing of wheat, and the second is the topdressing in spring. Traditional wheat cultivation, some one-time bottom application, no longer top dressing; some bottom fertilizer accounted for 60% to 70%, top dressing accounted for 30% to 40%, the top dressing time is generally from the greening period to the starting period; and some before the winter Add a fertilizer supplement when watering in winter. The above fertilization ratio and time allow nitrogen fertilizer to be re-applied in the early stage of wheat growth. In high-yielding fields, it will cause the early stage of wheat to grow too large and increase ineffective tillers. This will promote the growth of wheat before winter. The risk of lodging is increased in the early stage, and early senescence is easy in the later stage, which affects the yield and quality, and the utilization efficiency of nitrogen fertilizer is low.

Therefore, high-yield wheat fields should adopt nitrogen fertilizer backward shift technology, which reduces the bottom fertilizer ratio of nitrogen fertilizer to 50%, and increases the topdressing ratio to 50%. The bottom fertilizer ratio of high-fertility wheat fields is 30% to 50%, and the topdressing ratio is 50. % ～ 70%; At the same time, the spring fertilization time is moved to the jointing stage. Using this technology can effectively control the excessive proliferation of ineffective tillers and shape a robust plant type of flag leaves and inverted two leaves; establish a reasonable population structure after flowering that accumulates more photosynthetic products and allocates a larger proportion to the grains; improve late growth The vitality of the root system is conducive to delaying senescence and increasing grain weight; it is conducive to increasing biological yield and economic coefficient, and can ultimately significantly increase grain yield, which can increase yield by 10% to 15% compared to traditional fertilization; it can increase wheat grain protein and wet gluten content and extend Dough formation time and dough stabilization time, significantly improve the nutritional quality and processing quality of high-quality strong gluten wheat; reduce the loss of nitrogen fertilizer, and increase the nitrogen fertilizer utilization rate by more than 10%.

API

what is API?

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.
