| Abstract: | The concept of agricultural standard yield was introduced,and the knowledge model of agricultural water productivity ratio evaluation was set up.From the aspect of irrigation intensity and extent,the changes of agricultural water productivity ratio of different provinces in China were studied,the state of regional agricultural water productivity ratio was evaluated,and the corresponding irrigation strategies were analyzed according to the basic characters of regional water productivity ratio. |
| |
| Keywords: | knowledge model agricultural standard yield agricultural water productivity ratio irrigation strategy |
