Pollination net rooms built at the oil tree peony base. A. oil tree peony base; B. the net house for the bee pollination treatment (45 m×8 m), which is equally divided into three net rooms; C. the net house without pollinating insects; D. plane graph of the pollination experiment. FC, natural field control; HP, honeybee pollination; BP, ground bumblebee pollination; BC, blank control (without pollinating insects).

The stigma contact ratios of honeybees and ground bumblebees. The upper limit of the rectangle is the 75th percentile of the data, the lower limit is the 25th percentile, and the middle line is the 50th percentile. The vertical length of the rectangle represents the quartile range, and the solid squares (points) are the observed values.
