| Abstract: In order to compare the effects of special and new nanomaterials and electric heating wire on the growth and yield of non-heading Chinese cabbage, two nanowire treatments, one electric heating wire treatment and blank control were set up to carry out the cultivation experiment of 'Wuyueman' in a multi-building greenhouse. The results showed that the nanomaterial treatment and electric heating wire treatment promoted the growth of non-heading Chinese cabbage effectively under low temperature environment in early spring. Compared with control, the growth of non-heading Chinese cabbage was faster, the leaf area was larger, and the growth period was earlier. In terms of yield, T1 (1 nanowire in the growth layer and another under the soil surface), T2(2 nanowires under the soil surface) and T3 (2 electric heating wires under the soil surface) increased by 90.8%, 48.8% and 107.5%, respectively compared with the control, the effect of increasing production was remarkable. Based on the overall results, T3 had the best effect, followed by T1. The yield-increasing effects on non-heading Chinese cabbage of partial nanowire placed in the growth layer was better than that of all nanowires placed under the soil surface. |
