| Abstract: | The objective of the research was to understand the gas exchange,instantaneous water use efficiency(WUEi) and sap flow differences under 3 phosphorus fertilizer treatments(F0,F1,and F2) at different growth stages on the Loess Plateau in Shaanxi Province;and the correlation and regression relationship between leaf transpiration rate(Tr) and sap flow velocity were also investigated.Results showed that: under different treatments,the daily variation curve of leaf photosynthesis rate(Pn) had two peaks and the v... |
