The impact of high temperature weather factors on various growth stages of Pleurotus eryngii was analyzed to facilitate the rational control of the temperature within its growing environment and mitigate its effects. Methods such as urea resolution and nitrogen blue tetrazole photoreduction were employed to assess the protein growth rate of Pleurotus eryngii under different temperatures. Between 32℃ and 36℃,the protein growth rate in the primordium stage of Pleurotus eryngii surpassed that in other stages. As the temperature rose from 32℃ to 36℃,enzyme activities declined across all stages,with the mycelium stage exhibiting 776 U/gmf at 32℃ and the mushroom picking stage showing 527 U/gmf,marking the lowest superoxide dismutase activity. The trehalose content initially increased and then decreased with rising high temperatures,peaking at 34℃. Specifically,the trehalose content was highest in the primordium stage (0.102％) and lowest in the mushroom picking stage (0.008％). High temperature weather significantly influences the growth of Pleurotus eryngii. With the increase of temperature,it is characterized by an initial acceleration followed by a deceleration in protein growth,a decrease in superoxide dismutase activity,and a trend of first increasing and then decreasing of trehalose content.
