Dry matter transfer from vegetative organs
The transfer of stem biomass mainly appeared below the ear, with
transfer amounts of 1.80 Mg ha−1 (transfer rate: 36.3%) and
1.23 Mg ha−1 (transfer rate: 26.0%) at 12.0 and 13.5 × 104 plants
ha−1
, respectively, in 2014 (Table 3). The transfer amounts of leaf were
0.43 (transfer rate: 63.2%) and 0.27 Mg ha−1 (transfer rate: 44.3%) in
the ear, and 0.77 (transfer rate: 17.2%) and 1.58 Mg ha−1 (transfer
rate: 33.3%) above the ear in the two respective densities in 2014. The
total transfer amount were 2.54 (transfer rate: 34.6%) and
1.55 Mg ha−1 (transfer rate: 22.4%) below the ear, 0.69 (transfer rate:
31.0%) and 0.51 Mg ha−1 (transfer rate: 35.2%) in the ear, 1.73
(transfer rate: 21.0%) and 2.81 Mg ha−1 (transfer rate: 31.7%) above
the ear in the two respective densities in 2014. However, there was no
transfer below or above the ear at 12.0 × 104 plants ha−1 in 2015,
while transfer occurred in the leaf of the ear layer, with a transfer
amount of 0.05 Mg ha−1 (transfer rate: 9.3%). Similar to the results
from 2014, the transfer in stem mainly appeared below the ear, with a
transfer amount of 0.45 Mg ha−1 (transfer rate: 10.6%). The transfer
amounts in leaf were 0.26 Mg ha−1 (transfer rate: 42.1%) and
0.32 Mg ha−1 (transfer rate: 8.7%) in the ear and above the ear, respectively, at 13.5 × 104 plants ha−1 in 2015. The total transfer
amounts were 0.88 (transfer rate: 13.0%) below the ear, 0.14 (transfer
