图3 不同处理开花后旗叶叶绿素相对含量(SPAD) A, B分别表示2019-2020和2020-2021生长季开花后旗叶叶绿素相对含量。图中所示数据均为每处理测定的3次重复, **表示不同处理在0.01概率水平差异显著。

Fig. 3 Relative chlorophyll content (SPAD) of flag leaves after anthesis under different treatments A and B represent the relative chlorophyll content of flag leaves after anthesis in the 2019-2020 and 2020-2021 growing seasons, respectively. The data shown in the figure are all three replicates of each treatment. ** indicates significant differences between different treatments at the 0.01 probability level.
