Abstract:

In the present study, strawberry greenhouse with severe continuous cropping obstacles was used as the research object, the effects of four soil disinfection methods of high temperature control (T1), quicklime disinfection (T2), calcium cyanamide disinfection (T3), and dazomet disinfection (T4) on soil fungal diversity and soil fungal community structure were compared. It was shown that the soil fungal diversity under different soil disinfection methods were reduced to varying degrees as compared with the control (CK), and various alpha diversity indexes decreased as T4>T3>T2>T1. For soil dominant fungi at genus level (relative abundance>1%), the relative abundance of Fusarium, Thielavia, Mortierella, Verticillium and Acremonium were decreased under four soil disinfection treatments compared with CK, while the relative abundance of Chaetomium and Penicillium were increased. According to the impact of soil disinfection methods on soil fungal diversity and soil fungal community structure, the performance of dazomet disinfection was the best and was followed by calcium cyanamide disinfection. Given the economic cost, calcium cyanamide disinfection was a preferable choice.
