Solar storage wall utilization for polyethylene greenhouses as a passive heating system [electronic resource].

Includes references.

Trials were carried out to overcome the greenhouse air temperature drop within the cold nights of winter season, which affects the greenhouse crop production. Two different cheap materials of adobe and red brick were used as solar storage walls inside gable-uneven span type greenhouses. The greenhouses that comprised storage walls were compared with a control trial greenhouse without storing wall. Consequently the control greenhouse was compared with an open field testing. Soii covers were applied to study the effect of mulching on the soil heating under the effect of the solar storage wall presence. Crop residues of 5 em thick, black plastic mulch of 0.2 mm thick were compared with the bare soil without covers.
