How to fertilize high-yield winter wheat

According to the cultivation characteristics of winter wheat, the characteristics of required fertilizer and the actual situation of agricultural production, three links should be grasped in scientific fertilization: The first is to apply basic fertilizer. The farmer said that “Meat is rich in the fetus”, and there is an appropriate amount of nitrogen nutrition and phosphorus and potassium fertilizers at the seedling stage to make the wheat seedlings grow as early as possible. There is a certain number of healthy tillers before the winter, and they grow into panicles, increase grain, and gain weight after the spring. basis. The general set wheat yield indicator is 500 kg/mu, 15 kg of urea, 25 kg of ammonium phosphate and 15 kg of potassium chloride per mu. If compound fertilizer is applied, it is calculated according to the amount of N, P, and K contained in the fertilizer. Followed by skillful dressing. Dressing is beneficial to increase glutinous rice and increase propagation. After spring wheat seedlings turn green, they can use 10 kg of urea per mu, and apply irrigation to water in conditions where there is a weak wheat field, and water and water should be provided when conditions are met. For strong wheat seedlings, fertilizer and water management should be controlled during the jointing period to prevent lodging. Finally, foliar fertilization is carried out in the later stages of wheat growth.

Key Intermediates

Intermediate – Intermediate: A material produced during a drug substance processing step that must undergo further molecular modification or refinement to become a drug substance. Intermediates may or may not be isolated. Intermediates are the key products of the previous process of making APIs, which are different in structure from APIs.

for example:

Amoxicillin capsules are called preparations, amoxicillin is called API, and 6-APA is called intermediate.

Ceftriaxone sodium powder is called preparation, sterile ceftriaxone sodium is called API, and 7-ACA is called intermediate.

Our company specializes in providing key intermediates for various APIs

Intermediate is a very important type of fine chemical products. Its essence is a type of "semi-finished product", which is an intermediate product in the production of certain products. For example, if a product is to be produced, it can be produced from intermediates, saving costs and reducing It is widely used in the synthesis of medicines, pesticides, coatings, dyes and spices. In the field of medicine, intermediates are an important link in the industrial chain of the pharmaceutical industry. They are used for some chemical raw materials or chemical products in the process of drug synthesis. In a word, they are used to produce APIs.
