| Abstract: |
| The effects of drip-irrigated planting patterns on water-salt transport, soil temperature, growth, yield and water use efficiency of cotton Nongfeng 133 were analyzed. Test-pit experiments were set under three drip-irrigated planting mode (M1, M2, and M3) and flood-irrigated planting mode (M4) as the control. The results showed that, M2 mode kept the soil water and salt conservation in root zone and it benefited to cotton growth and water use efficiency. Modes of M1 and M3 were worse than M2 and M4 was the worst. Except M4, other plastic film mulching cultivation modes could improve soil temperature quickly and decrease temperature slowly. Water efficiency and yield varied among capillary arrangements, irrigation methods and film width. Water use efficiency and average yield of M2 were 6 701 kg·hm-2 and 1.07 kg·m-3 respectively and were much higher than which of other modes.The indexes of M4 were only 4 908 kg·hm-2 and 0.77 kg·m-3 respectively. These findings suggested that the super wide film and mechanical picking pattern might be a good choice, especially M2,considering increase agricultural water resource efficiently and yield. |
