*2.1. Measurement Results of Basic Physical Parameters of Cabbage*

The determination results of the basic physical parameters of cabbage are shown in Table 1. The vertical diameter of the cabbage ball was (162.3 ± 38.16) mm, the transverse diameter of the sphere was (163.8 ± 25.84) mm, the weight of cabbage was (1.91 ± 0.68) kg, the diameter of the cabbage rhizome was (28.71 ± 4.56) mm, and the expansion degree of cabbage was (325.6 ± 40.89) mm. The measurement results can provide a theoretical basis for the spatial layout of the cabbage harvesting device.
