Effects of Soybean Canopy and Sweet Potato Canopy on Soil Temperature Variations beneath Mulch Film

Description

The purpose of this experiment was to determine how the soil temperatures beneath the mulch were influenced by different types of canopy. Soybeans and sweet potatoes were used for the experiment, and were grown in an open field and in a greenhouse.The influence of canopy on the soil temperature was smaller in the greenhouse than in the open field. The differences of influence exerted by different canopy types were smaller when there was mulch than when there was no mulch. Soil temperature thresholds determine the order relation between the soil temperatures of two plots. The comparison of such thresholds revealed that the differences of influence on the thresholds were larger in the greenhouse than in the open field, both when the soil temperature was at its lowest (at 6:00) and its highest (at 15:00). In terms of the shadow ratios by canopy, prostrate canopy like sweet potatoes exerted greater influence on the thresholds than erect canopy like soybeans. This was more so in the greenhouse than in the open field. On the relationship between the thresholds and meteorological factors, the meteorological factors that exerted influence on the lowest and highest soil temperatures were different between the greenhouse and the open field.
