Method for cultivating oyster mushroom

Pleurotus ostreatus wood rot fungi, adaptability, and therefore easy to grow successfully. Generally used raw materials cultivation. In order to make full use of land and space, to develop in a three-dimensional manner, increase the efficiency of the use of solar greenhouses to increase its efficiency, reduce the contamination of germs, increase production and quality, and promote the cultivation of clinker suitable for annual production.

The method of cultivating using clinker is to weigh the culture materials according to the proportion, the water content is controlled at about 65%, and the bags can be bagged evenly. Use high-density low-pressure polyethylene plastic bags, specifications 20 cm 45 cm. Immediately after bagging, stoves were sterilized by atmospheric pressure and kept at 100°C for 10 to 15 hours. When the bag was cooled below 25°C, inoculation was performed. All disinfection work should be done. Keep bacteria at about 20°C after inoculation. Germs need to be protected from light, dry, and pay attention to ventilating and ventilating the chamber. After 20 to 30 days, the mycelium can be covered with culture materials, and the bag can be loosened to allow oxygen to penetrate into the bag to accelerate the physiological maturity of the hyphae, and then transfer into a sterile mushroom house for mushroom management.

The advantage of clinker cultivation is that it is conducive to eating mycelium, easy to control the infection of bacteria, and the bioconversion rate is improved.

Clinical PW A detection
Port wine stains ( PWS ) is always a birthmark . It is caused by a vascular anomaly. PA imaging could provide real-time information about the thickness of the skin and diameter. depth, distribution of blood vessel , which provide significant help with clinical diagnosis and treatment.

PAI VS. OCT
Image depth : PA 2 mm
OCT 0.4 mm
Functional identification : With optical fingerprint characteristics ,P A could specificity imaging blood vessels , eliminates the interference of hair follicle, sebaceous glands.


The clinical testing has been carried out in 301 and guangzhou military general hospital , testing and statistic all kinds of PWS lesions in patients with vasculal parameters , in order to establish the classification and quantitative treatment of PWS.
