Abstract：In order to clarify the influence of different altitudes and shed types on the supply cycle of fresh Lentinula edodes(L. edodes)in the main producing areas of L. edodes,89 samples of L. edodes growers in 23 townships in simple,simple-standard and standard sheds distributed at low,middle and high altitudes were collected by combining question-naire survey and field investigation. Centering on the supply duration of fresh L. edodes,the influences of altitudes and shed types on the supply cycle of fresh L. edodes were analyzed. The results showed that the supply duration of fresh L. edodes in simple type and simple-standard type shed was negatively correlated with altitude,i.e. the supply duration of fresh L. edodes at low and middle altitude was longer than that at high altitude by about 34-49 d. For the standard type shed,the supply duration of fresh L. edodes was positively correlated with altitude,i.e. the higher the altitude,the longer the supply duration of fresh L. edodes. The supply duration of fresh L. edodes in standard shed at high altitude was signifi-cantly longer than that at low and middle altitudes of about 42 d and 35 d,respectively. At the same altitude,the supply duration of fresh L. edodes was positively correlated with the shed type,i.e. the better the type of shed,the longer the supply duration of fresh L. edodes. Especially,the supply duration of fresh L. edodes in the standard type shed at high altitude was significantly longer than that in the two simple type sheds by about 86 and 85 d. There was no significant difference in the supply duration of colored L. edodes between the two simple type sheds by altitude,but the supply durations of col-ored L. edodes in the standard type shed at middle and high altitudes were significantly longer than that in the low altitude by about 33 d and 30 d,respectively. Furthermore,the supply durations of colored L. edodes both in the simple-standard type and standard type shed at middle altitude were significantly longer than that in the simple type shed by about 52 and 36 d,respectively. In conclusion,the supply cycle of fresh L. edodes in the two counties was from September-October to April-June of the following year,and the supply duration was affected by different regions,altitudes and shed types. High altitude and high quality shed could prolong the supply cycle and increase the yield of L. edodes. Under the premise of quality assurance of shiitake,the supply durations of fresh L. edodes in simple-standard type at low and middle altitudes were longer.
