How to use spent Armillaria-infected wood in Polyporus umbellatus cultivation
Polyporus umbellatus is also known as Di Ling, Polyporus umbellatus Maitake (Japan), wild boar food, pig dung Ling, etc. It is one of the commonly used traditional Chinese medicinal materials, mainly obtained by digging up wild specimens for medicinal use. As natural resources gradually decrease, the contradiction between supply and demand is becoming increasingly acute. In particular, modern medicine has proved that the Polyporus umbellatus polysaccharides B—(1-4) and B—(1-6) contained in the sclerotium of Polyporus umbellatus are a nonspecific cellular immunostimulant, which can significantly strengthen the function of phagocytes in the reticuloendothelial system, inhibit the growth of tumor cells, and reach an inhibition rate of up to 99.5% against tumors in mice, making it one of the medicinal fungi with relatively good anticancer effects and attracting widespread attention from medical and pharmaceutical departments at home and abroad. To solve the severe shortage of medicinal sources and the situation of supply falling short of demand, in addition to paying attention to protecting existing resources, vigorously carrying out resource surveys, and expanding the harvesting area, research work on artificial cultivation and mycelial fermentation of Polyporus umbellatus is also very important.
