Abstract：Greenhouse is the main place for the growth and development of Lentinula edodes.Evaluating the tempera-ture regulation ability of different greenhouses can provide reference for the construction of greenhouse in L.edodes production areas.Taking commonly used L.edodes greenhouses from Lushi county,Xixia county and Yuanyang county in Henan as samples,temperature data from inside and outside the greenhouse were collected.Based on the temperature conditions required for L.edodes mycelium growth and fruiting,the temperature variation trends and regulation capaci-ties of the greenhouse under different meteorological conditions were compared.These three regions selected June to August as the high-temperature period,and December to February as the low-temperature period.During the high-tem-perature period,the simple greenhouse showed no cooling capacity for daily maximum temperature under high-tempera-ture conditions,with an internal temperature increase of 0.2 to 2.3 ℃.The simple standard greenhouse,small linkage greenhouse,double-net double-film arched greenhouse,and greenhouse had cooling capacities of 1.8-5.0 ℃,5.0-8.3 ℃,3.2-7.9 ℃,and 3.0-7.4 ℃,respectively.During the low-temperature period,the corresponding heating ca-pacities for these greenhouses were 2.5-4.2 ℃,3.0-5.6 ℃,6.2-9.8 ℃,4.5-10.1 ℃,and 5.6-9.8 ℃,as well as the heat re-tention capacities of 0.6-0.9 ℃,2.2-3.7 ℃,3.4-6.9 ℃,8.9-14.1 ℃,and 8.3-13.0 ℃,respectively.Different types of L.edodes greenhouse exhibit varying temperature regulation capacities.Growers should choose appropriate greenhouse type based on the local environment to reduce economic losses caused by insufficient temperature control.
