Edible fungi contain a variety of functional ingredients,such as polysaccharides,peptide amino acids,nucleosides,triterpenes,minerals,vitamins,etc.,so they have important medicinal value. In order to understand and rationally develop wild edible( medicinal) fungus resources in Yunnan,the main trading species of wild edible( medicinal) fungi in Yunnan Province were investigated,and the biological characteristics and medicinal value of these wild edible( medicinal) fungi were summarized.Moreover,the development prospects of wild edible fungi in Yunnan Province in edible and medicinal fields were discussed.展开更多

In the power supply side,renewable energy generators generate power by wind and other natural conditions,leading renewable energy output a certain randomness. However,the low marginal generating cost and the reduction of carbon emissions,and thus brings a certain advantage for renewable energy compared to alternative energy. Electricity,as a special commodity,stable and adequate power supply is a necessary guarantee for economic and social development. Power shortage situation is not allowed in the power system,and the extra power needs to be handled for the purpose of safety. In this paper,the hybrid power generated by renewable energy generators and traditional energy generators is used as power supply,and then the electricity market sells hybrid power to electricity consumers,the hybrid power system determines the optimal daytimeprice,nighttime price,and the optimal installed capacity of the renewable energy suppliers. We find that the installed capacity of renewable energy increases first and then decreases with the increase of the price sensitivity coefficient of traditional energy supply. Electricity demand is negatively related to electricity price in the current period,and is positively related to price in the other period. The average price of day and night is only related to the total potential demand of day and night and the total generation probability of renewable energy. The price difference between daytime and nighttime is positively related to potential electricity demand,and negatively related to the sensitivity coefficient of electricity price.展开更多
