| Abstract: | The plant growth and water use in winter wheat under sprinkler irrigation were investigated with field experiment. The relationship between relative yield and relative water use is formulated. Sensitive indexes of winter wheat at different growing stages to water deficit also were presented. Based on these data, a optimal irrigation scheduling under sprinkler irrigation for winter wheat were showed as well in this paper. |
