图6 糜子各生长指标与产量的回归分析(2019-2020) 图中产量为实测数值; 各生长指标为同一小区4个生育时期的平均值; 实线为回归线(n = 30)。**表示回归模型在0.01水平上显著。

Fig. 6 Regression analysis of the responses of grain yield to different growth parameters in 2019 and 2020 In the figures, the grain yield is measured values, each growth parameter is the average of four growth stages in the same plot, the solid lines are regression lines (n = 30). ** denotes that the regression is significantly difference at the 0.01 probability level.
