Abstract:
Taking protective farmland cultivated with Capsicum annuum L. as research object，changes of ground temperature with time and depth of soil in protective farmland derived from dark brow forest soil was investigated.The results showed that the diurnal variation of soil temperature at different depths presented the sine curve，fluctuation of daily maximum ground temperature was large than fluctuation of daily minimum ground temperature.With the increase of soil depth，thermal storage time became longer，thermal loss time became shorter，times of heat storage and loss with soil depth were lagged，and the strength was small.The daily amplitude of fluctuation of ground temperature affected by environment factors decreased with soil depth in protective farmland.
