The scanner position schemes: a in Rugao and b in Xuzhou. The varieties in the set of three rows are consistent; the red solid circle points stand for the scanning positions of the LiDAR instrument. Note: D represents the line spacings (D1: 25 cm, 2.4 × 106 seedlings/ha and D2: 40 cm, 1.5 × 106 seedlings/ha), V represents the varieties (V1: Shengxuan 6 and V2: Yangmai 16), and N represents the three levels of pure nitrogen (N0: 0 kg/ha, N1: 150 kg/ha, N2: 300 kg/ha)
