图3 不同收获时期玉米籽粒破碎率、含水率、力学强度变化(2018) 箱型图中的箱体部分代表50% (25%~75%)样本的分布区域, 为四分位区间(IQR)。箱体内实线为中位线, “?”为异常值点, “+”为均值。图中不同小写字母表示不同时期在0.05水平下差异显著。

Fig. 3 Changes of maize grain broken rate, moisture content and mechanical strength in different harvest dates (2018) The box part in the box diagram represents the distribution area of 50% (25%-75%) samples, which is a quadrant interval (IQR). The solid line in the box body is the median line, “?” is the abnormal point, “+” is the average. Different lowercase letters above boxes show significant differences at the 0.05 probability level in different periods.
