Effect of Climate Warming on Winter Wheat in Baoding - A Case Study of Rongcheng County |
| |
| Abstract: | Based on daily meteorological data of agricultural meteorology stations in Rongcheng from 1981 to 2015, the changes of winter wheat suitable sowing period, negative accumulated temperature during winter and the water requirement from jointing to heading stage in Baoding City were analyzed. The results showed that: the winter wheat suitable sowing period was postponement. The rate of change of the trend was 0.759d / 10a-0.627d / 10a, but the trend of change was not obvious. The negative accumulated temperature showed a decreasing trend during the overwintering, decreasing trend rate was 24.3 ℃ . d / 10a. ; Water requirement from jointing to heading stage showed a downward trend, while downward trend rate was 2.3mm / 10a, the tendency of change was not obvious. |
