The pear tree winter tube should grasp the following points: Qingyuan and Tubai will promptly clean up the fallen leaves, weeds, diseased fruits and diseased branches in the orchard and focus on incineration or deep burial to eliminate the spread of harmful bacteria. A 1:5 lime aqueous solution was sprayed on the trunk. Deep-turning the root plate deep-turning the root plate can loosen the soil and enhance the soil permeability. At the same time, it can freeze insect pests and eggs, or allow birds to eat the eggs and reduce the pests in the coming year. Plastic pruning The pruning of pear trees should be based on factors such as tree species characteristics, tree age and growth, pruning response, natural conditions, and cultivation and management levels. The saplings should be dominated by plasticity. According to the tree species and planting density, the tree shape should be determined to promote its early results and early high yield. For trees entering the fruit period, trees should be lightly transferred and sparsely cultivated, so as to avoid the formation of baldness at the base of the main branch due to lack of light in the interior, and at the same time, the rejuvenation result should be constantly updated to enhance its growth and maintain good results. ability. It is also necessary to pay attention to the coordination of the relationship between the large, medium, and small fruiting branches, so that the tree shrubs can be distributed evenly in order to increase yield and improve quality. The aging trees should be updated and rejuvenated in time, and new canopies should be re-cultivated. New branches should be kept as much as possible, and they should be cultivated into fruiting branches as soon as possible.
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.
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.

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