图2 2021-2022年产量及其构成因子、干物质和氮肥利用率的相关性分析 P：有效穗数；GW：千粒重；SP：穗粒数；GT：结实率；Y：产量；SDW：茎干重；LDW：叶干重；PDW：穗干重；TDW：地上部干物质总积累量，“*”表示P < 0.05水平相关性显著。

Fig.2 Correlation analysis between yield and its components, dry matter and nitrogen use efficiency from 2021 to 2022 P: effective panicle number, GW: 1000-grain weight, SP: number of grains per panicle, GT: seed-setting rate, Y: yield, SDW: stem dry weight, LDW: leaf dry weight, PDW: panicle dry weight, TDW: total aboveground dry matter accumulation,“*”indicates significant correlation at P < 0.05 level.
