In the summer, the cultivation of Pleurotus ostreatus in bag materials may cause the death of a large number of small mushrooms after fruiting. The main reasons are the following four points. Preventive measures should be taken early.
If the temperature is too high after the primordium of Pleurotus ostreatus is formed, if the temperature is high (above 30°C), the cap will gradually wither and cause a large number of deaths. During the mushrooming period, the temperature is too high and the well water can be used to cool the mushroom room. Outdoor mushrooming, mushroom shed should be covered with thick straw or straw shade, and enhance ventilation.
If the water lacks the young buds of Pleurotus ostreatus, if the relative humidity of the air in the mushroom room or shed is lower than 80%, the body of the mushroom will wither and die due to lack of water. After spraying, water should be sprayed 4 to 5 times a day. When water is sprayed, it should be less, even and fine, and the relative humidity should be kept at about 90%.
Overspray water during the expansion of mushroom fruiting body, such as water spray is too easy to edema, yellow ulceration, but also susceptible to bacteria and death. Therefore, when spraying the water to the mushroom house (shed), the water should be sprayed on the ground and the surrounding walls, and it should not be directly sprayed onto the fruiting bodies of the young mushroom. At the same time, it is necessary to correctly grasp the amount of water spray and do not spray too much.
When the concentration of carbon dioxide in a poorly ventilated mushroom room or shed exceeds 0.5%, it is easy to form a small, large-sized mushroom with a large fist or handle. In order to ensure fresh air in the mushroom room, it is necessary to pay special attention to it at high temperatures.
Sterile Vials are produced by aluminum caps, non-latex butyl stoppers and SCHOTT Neutral Type I glass vials. They are approved by cGMP and FDA with internally sterile.The production process is carried out under strict Class 100 workshop. Finished vials can meet the FDA`s authorised 14-day sterility test. Sterile vials are primarily used for mixing different medications or solutions for injection or research applications like HCG, heparin, lidocaine, diabetic medications and morphine for intravenous or syringe injections. Some drugs may need to be diluted or mixed with sterile water or other drugs. Sterile vials are also used for nuclear medicine, PET-CT, Liquid collection.
