In order to explore the effects of different planting and harvest periods on the flavor and quality of Stropharia ru-gosoannulata,three different planting and harvest period treatments were set up in the base of Xiangtan Institute of Agricul-tural Sciences in Hunan Province in 2018(T1:planted on October 18th and harvested in the first batch in March of the following year;T2:planted on October 18,and mushroom again after the first harvest in March of the following year,and the second harvest in April;T3:planted on November 24 and the first harvest in May of the following year).The agronomic characters,contents of polysaccharides,total triterpenes and the relative contents of volatile flavor compounds in the growing period of Stropharia rugosoannulata were compared and analyzed.The results showed that the contents of agronomic charac-ters and active components of Stropharia rugosoannulata in T1 treatment were better,followed by T2 treatment,and the con-tents of agronomic characters and active components in mature stage and umbrella opening stage were better,and the cate-gory and content of volatile components in growing stage and mature stage were higher.According to the comprehensive analysis,the flavor and quality of Pleurotus ostreatus planted in the middle and late ten days of October and harvested in the first mature period of the following year were the best.
