Abstract: | The coupling degree of the main crops' water demand and the rainfall and the water ecological adaptability in Tongxin County were studied to provide a theoretical basis for making a reasonable decision scheme of dryland cropping sys-tem. The test results show that the coupling degree ordering of 4 kinds of main crops' water demand and the rainfall is wa-termelon〉potato〉maize〉oil sunflower and the ecological adaptability index ranking is potato〉watermelon〉 maize〉oil sunflower. |
