Winter species of mushrooms, young buds poor adaptability to the outside world, if the management of out of control, will take place died of mushroom buds. Measures to prevent the death of young buds:
Control the temperature to prevent freezing. In the fall, mushrooms were introduced into the winter and they encountered cold currents. When the temperature drops below 5°C and continues for several days, the young buds will freeze to death, showing a soft bud. After the occurrence of young buds in winter, we must pay attention to the weather forecast to prevent freezing of young buds. In the event of weather below 5°C, we must use fire paths to warm them up.
Control the temperature to prevent it from drying out. In winter, the climate is dry. Generally, the relative humidity of the air is about 40%. Under such environmental conditions, young buds can easily die. To prevent the young buds from dying, sprinkle the water on the ground inside the mushroom shed or pass water vapor into the mushroom shed to increase the relative humidity of the air.
Control ventilation to prevent mushroom death. Young bud period can not let the wind directly blow young buds, so as to avoid the mushroom body surface water evaporates too fast, causing the mushroom body to lose water for too long, too much and die. Covering the sheds during the growth period of the young buds, it is necessary to ventilate them in a windless weather, remove the membranes for ventilation for a short period of time, and timely moisturize the membranes.
Control air damage and prevent poisoning. Warming in the winter shed, the burning gas can easily cause young carbon dioxide, sulfur dioxide and carbon monoxide poisoning and die. When the mushroom shed is warmed up, it is necessary to adopt a fire passage through the chimney to discharge the waste tobacco out of the mushroom shed; the shed must be ventilated regularly to discharge harmful gases.
Temperature scales are controlled to prevent roasting. If the temperature is too high during flowering, the entire batch of young mushrooms will often be roasted. The highest temperature for the growth of mushroom buds is 20°C. The temperature should not rise too high during flowering and the time should be short. At the same time strengthen ventilation and humidity.
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.
