Abstract: |
The sensitivity coefficients of main crops to water stress in different development periods in three representative stations on Loess Plateau in Gansu was calculated based on the data of climate,crop yield,soil moisture and crop growth.The results show that the sensitivity of different kind of crops at different development periods varies.Winter wheat is more sensitive in booting to anthesis than in any other development periods,corn is more sensitive in jointing to heading;while spring wheat is only sensitive in jointing to athesis. |
