Description |
Effect of some kinds of mulch on air temperature and soil temperature were evaluated using the ratio of daily temperature range. This experiment was conducted from September 26 to December 15 in 2000. A total of 14 experimental plots were prepared by seven kinds of mulch, and with and without plants.There were no clear relationships between albedo on the mulch surface and surface temperature among the mulch plots. The differences of mean air temperatures of 10 points among the plots were small, but those of diurnal range were large. On the soil temperatures, the differences were large. The ratios of diurnal range (Air temperature 5cm height / Soil temperature 10cm depth) in the plots with plant became larger than those of the plots without plant. On the whole, differences of mulch effect of air temperature were small. Conversely it became large in the case of soil temperature. Effects by mulch film alone differed in the plots with or without plant. Effect of micrometeorological factors on the air temperature at each plot became smaller than those of the soil temperature. |
