Abstract

The purpose of this paper was to clarify the effects of prostrate and erect canopies on the soil temperatures and the deviations of 10 soil temperatures beneath film mulch in a field and inside a glasshouse. Six experimental plots were prepared inside and outside the house. These plots had either no mulch, or black mulch, and had either prostrate canopy, erect canopy, or no canopy. The deviations of soil temperature were larger inside the glasshouse than in the field. Further the deviations among canopy types and the time of day were very small in the house, as compared with those in the field. In order to determine the high-low relationships of the soil temperatures between two plots, threshold values of soil temperatures were adjusted. Comparison of the threshold in the field and inside the glasshouse showed that a higher threshold was required inside the glasshouse than in the field to determine the high-low relationships. The effect of the presence or absence of a canopy on the threshold in the glasshouse was less than that in the field.
