The Observation on Soil Temperature from Kiwi Fruit Garden and Parent Material Xiashu Loess, Liuhe Nanjing, China

Abstract

Soil temperature is one of the most important soil physical characters. The soil samples from different parent materials, Xiashu Loess from Nanjing Lvhang Kiwi fruit garden and alluvium of Yangtze River from Yangzhou Chahe, was tested on the temperature change with time and others in this study. Preliminary conclusions have been drawn: The firstly, soil temperatures change are consistent with air temperatures. Secondly, soil temperature change greatly in 10cm depth at 24:00 and 15cm depth at 14:00 in April, so soil temperatures management should be strengthened for Kiwi fruit garden in this month. Thirdly, soil temperatures from Kiwi fruit garden drop from 30ËšC or so in September to 15ËšC in October. Fourthly, applying the regression equations forecast the soil temperatures (y) by air temperatures (x).
