| Abstract: |
| Six different irrigation modes and two fertilization levels were set.Taking irrigation with fresh water as the control, the saline water with 3 g/L mineralization was used as irrigation water, and the effect of different rotational irrigation mode and fertilization amount on the growth of maize and salt accumulation of soil were studied. The results showed that, maize growth and production were improved by more fertilizer, maize quality were improved by irrigation with saline water, and the yield of maize decreased at the same time; specially, plant height, leaf area and yield of maize were affected obviously by two rounds irrigation with saline water; soil salinity was obviously increased by more salt water irrigation and fertilizer application. Therefore, the combination of saline-fresh-fresh-fresh irrigation order and 560 kg/hm2 fertilization scheme was selected as the optimal mode. |
