Abstract:
As an important cash crop,edible mushroom plays a powerful role in consolidating the results of poverty alleviation and promoting rural revitalization in Guangxi,and its price fluctuations directly affect the interests of producers and consumers.The wholesale prices of six Guangxi staple edible mushroom species were analyzed by Census X12 seasonal adjustment method and HP filtering method from 2017 to 2023,the price trend pattern and fluctuation characteristics was obtain,in order to provide reference for development of edible mushrooms industry.The results showed that Guangxi edible mushroom prices had obvious seasonal and cyclical fluctuation characteristics,seasonal fluctuations more than one year cycle,shiitake mushroom had the longest fluctuating cycle,shiitake mushroom had the shortest cycle;reishi mushroom had the largest difference between peaks and valleys in its cycle,and fresh shiitake mushroom had the smallest;the average price of reishi mushrooms was the highest and that of fresh black fungus was the lowest during the study period,while the average price of dried products was much higher than that of fresh products;regarding the coefficient of variation,the prices of dried and fresh shiitake mushrooms and shimeji mushrooms were relatively stable,while the prices of reishi and bisporus mushrooms were more volatile.Price stabilization should be achieved by strengthening macroeconomic regulation and control,improving the price monitoring and early warning system for edible fungi,strengthening the construction of storage and preservation facilities,and expanding the power of new business entities.
