The quality of strains is the key to the high yield of Pleurotus ostreatus. The high-quality Pleurotus ostreatus secondary and tertiary strains should have the following characteristics: The mycelium is dense, white, and grows thick and uniform. It is villous and has wall-climbing. A small amount of coral-like mushroom buds appear on the surface of the medium. The bacterial age is suitable for 20 to 25 days. The mycelia of the strain section is obvious and there is a clear mushroom fragrance. If there are a large number of fruit body primordium on the surface of the culture medium, it indicates that the strain is mature and should be used as soon as possible.

Before introduction, it is necessary to clarify the temperature type of bacteria, and then determine the temperature type of the bacteria according to their own conditions and the temperature of the mushroom. During August-September, Pleurotus ostreatus is cultivated because the temperature is high, and the high temperature above 30°C sometimes appears during the fruiting period, and the temperature gradually decreases after entering the month of October. In order to ensure the normal mushrooming during high and low temperatures, the selected mushroom is used. The species should be able to both withstand high temperature and can take into account the excellent strains of low temperature mushroom. From mid-August to mid-September, Pleurotus ostreatus is cultivated, and Jiangdu 109 and Huafeng No. 1 are selected; from the late September to mid-October, Pleurotus ostreatus is cultivated, and in the year 9703 and P50 are selected; from the late October to the end of November, cultivated Pleurotus ostreatus is selected. Ping Wang, 8801. If the type of strain used is inappropriate, it is not suitable for cultivation in the autumn. Be careful when introducing the strain. In addition, strains should be selected based on local natural resources. The main raw materials for the cultivation of Pleurotus ostreatus are cottonseed hulls and corn hearts. The ability of different varieties to decompose culturing materials is different, and bacteria species that are suitable for cultivating materials should be selected.

Hemodialysis Catheters are used to:

  • Give long-term medicine treatment for pain, infection, or cancer, or to supply nutrition. A Hemodialysis Catheter can be left in place far longer than an intravenous catheter (IV), which gives medicines into a vein near the skin surface.
  • Give medicines that affect the heart, especially if a quick response to the medicine is wanted.
  • Give large amounts of blood or fluid quickly.
  • Take frequent blood samples without having to "stick" someone with a  needle.
