| Abstract: |
| Compared with the open field test, we studied the effect of film slit furrow irrigation on soil moisture content, soil temperature and status of summer maize during growing period. The result showed that the soil moisture content is higher than the open field when covered by plastic film, and, on average, it is 5.5% higher in 0～40 cm layer, 2.9% higher in 40～80 cm layer and 1.3% higher in 80～120 cm layer. In addition, after film covering t
he soil temperature in tillage layer is higher than that in the open field, and the varying range of soil temperature with film covering at 8∶00, 14∶00 and 20∶00 was 1.13℃, 0.57℃ and 0.34℃, respectively, comared to 2.06℃, 1.38℃ and 1.01℃ in open field. Under the same irrigation conditions, the plant height and dry matter of summer maize is 49 cm and 126 g/plant respectively higher than that in the open field. So film covering is conducive to the growth of summer maize. |
