Ginger rhizomes absorb less nitrogen, phosphorus and potassium in the seedling stage, and slowly increase the absorption of phosphorus in the vigorous growth period, and the demand for nitrogen and potassium soars, especially in the early period of the vigorous growth period, which requires the most potassium fertilizer, followed by nitrogen fertilizer; In the middle and late stages of the vigorous growth period, nitrogen fertilizer was absorbed more than potassium fertilizer, and potassium fertilizer was absorbed more than phosphate fertilizer. Autumn is the time when ginger requires the most fertilizer. Therefore, in production, formula fertilization is carried out according to the fertilizer requirement of ginger, and timely application of nitrogen fertilizer will help increase production. The fertilization of ginger is divided into basal fertilizer and topdressing, and the principle of "applying enough basal fertilizer and topdressing in time" should be adopted. The base fertilizer is divided into organic fertilizer, cake fertilizer and chemical fertilizer. The organic fertilizer is combined with soil preparation and spreading before sowing. Generally, 5-8 cubic meters of high-quality decomposed chicken manure is applied per mu, and then plowed; cake fertilizer and chemical fertilizer are applied in furrow, that is, crushed before planting The cake fertilizer and chemical fertilizer are concentrated in the planting ditch, generally 75-100 kg cake fertilizer, 50 kg nitrogen, phosphorus, and potassium compound fertilizer or 25 kg each of urea, superphosphate and potassium sulfate are applied per mu. In addition to applying sufficient base fertilizer, top dressing is generally performed three times. The first top dressing is done when the seedling is about 30 cm high and has 1-2 branches. This top dressing is mainly nitrogen fertilizer, and 20 kg of ammonium sulfate or diammonium phosphate can be applied per mu. Before and after the beginning of autumn, the ginger seedlings are in the three-branched period, which is the transition period for ginger growth and the transition period for nutrient absorption. This top dressing is very important for the formation of ginger yield. Since then, the plant growth has accelerated and a large amount of nutrients have been accumulated. Product organs. Therefore, the demand for fertilizer and water increases. In order to ensure the high yield of ginger, the second top dressing is carried out by removing the ginger grass or removing the ginger shed before and after the beginning of autumn. This top dressing plays an important role in promoting growth and rhizome expansion. The fertilizer is required to be large in quantity, comprehensive in nutrition, and long-lasting fertilizer effect. This top dressing should be combined with long-lasting farm manure and quick-acting chemical fertilizer. Use 70-80 kilograms of crushed cake fertilizer per mu, or 500 kilograms of decomposed high-quality dried manure, plus 25-50 kilograms of compound fertilizer. Open a fertilization ditch on the side of the ginger seedling 15-20 cm from the base of the plant, and spread the fertilizer Put it into the ditch and mix it with soil and fertilizer, then cover the ditch with soil, cultivate the soil, and finally pour water.

Drug Intermediates -Pharmaceutical intermediates: A material that is produced during a process step of the drug substance and must undergo further molecular changes or refining before it becomes a drug substance. The intermediates can be separated or not separated.
Active Pharmaceutical Ingredient (APIS)(or Drug Substance) : Active Pharmaceutical Ingredient (API)(or Drug Substance) : Any substance or mixture of substances intended to be used in the manufacture of pharmaceutical products and, when used in pharmaceutical products, to be an active ingredient in pharmaceutical products. Such substances have pharmacological activity or other direct effects in the diagnosis, treatment, symptom relief, management or prevention of disease, or can affect the function and structure of the body. As can be seen from the definition, the Intermediates APIS is a key product of the previous process of manufacturing the API and has a different structure from the API
Finally, for example, amoxicillin capsules are called preparations, amoxicillin is called APIS, and 6-APA is called Veterinary Intermediates APIS.
Penicillin potassium for injection is called preparation, penicillin potassium is called Veterinary raw materials, and green potassium industrial salt is called intermediate
