Figure 1

Effects of the interaction between seeding rate and nitrogen rate on the photosynthetic potential of rice, PAR interception rate at different leaf positions, and plant height 10 days after flowering under dry cultivation. (a) Photosynthetic potential; (b) interception rate of light energy at different leaf positions; (c) plant height; (d) pictures of plant height using Origin software to process and merge pictures. (e) Rice growth after flowering under dry cultivation. (f) Growth of rice at the mature stage under dry cultivation. Different letters with the same sowing amount indicate a significant difference at P < 0.05. The figures were prepared and combined using Origin 2018 (www.originlab.com).
