图6 籽粒产量与地上部吸磷量的关系和各产量水平下单位籽粒磷素需求量 图a中实线表示拟合曲线, 虚线表示95%预测区间, **显著性为P<0.01; 图b中实线表示中值, 虚线表示平均值, 箱型边界表示75%和25%的四分位数, 上下边缘表示90和10百分位数, 圆圈表示95和5百分位数。 |
Fig. 6 Relationship between grain yield and aboveground P uptake, and P requirement per 100 kg grain (a) The solid line represents the relationship and the dashed lines represent the prediction band (P = 0.95), **significant at P < 0.01; The solid and dashed lines indicate median and mean, respectively. (b) The box boundaries indicate the 75% and 25% quartiles, the whisker caps indicate 90th and 10th percentiles, and the circles indicate the 95th and 5th percentiles. |
