Figure 3.
Photosynthetic rate, nitrogen accumulation, and transfer in leaves and stems. In (a–e), TPM, CPM, SPM, and CK represent an ordinary photovoltaic panel, a checkerboard photovoltaic panel, a translucent photovoltaic panel (with a light transmittance of 40%), and a comparison with field treatment, respectively. B and R denote the positions directly below and rear of the photovoltaic panel, respectively. Different lowercase letters represent significant differences between treatments at the 5% level. In (a), the number represents the number of days entering the grain filling stage.
