| Abstract: |
| Experiment was conducted to study soil temperature of partial root-divided alternative border irrigation applied in greenhouse capsicum,and the results indicated that the shallow layer soil temperature increases quickly and changes greatly,the peak temperature time of soil temperature in different depth postpones with the depth increasing;the average temperature of partial root-divided alternative border irrigation(wet side and dry side)is higher than that of general irrigation,the shallow layer soil temperature in wet side is lower than that in dry side from 8 to 14 o'clock,the soil temperature in wet side is higher than that in dry side in each depth from 14 to 18 o'clock;everyday the shallow layer soil temperature and air temperature become the line related at the same time,during one day the shallow layer soil temperature and measuring depths become an exponential function;the temperature-varying ranges and measuring depths could be fitted into an exponential function,and soil temperature has close relation with soil moisture. |
