Fig. 2 Cumulative nitrogen application chart under different nitrogen fertilizer strategies from 2021 to 2022 A represents the nitrogen accumulation dynamics of fixed nitrogen N1, N2 and N3 treatments for XS134 and HHZ rice in the 2021-2022 season. B, C, D and E represent the nitrogen accumulation dynamics of dynamic nitrogen RTNM, S34, S37 and S40 treatments for XS134 and HHZ rice in the 2021-2022 season, respectively. 21XS: rice Xiushui 134 in 2021; 21HHZ: rice Huanghuazhan in 2021; 22XS: rice Xiushui134 in 2022; 22HHZ: rice Huanghuazhan in 2022. Treatments and abbreviations are the same as those given in Table 1.
