| 英文摘要 | Field experiments were conducted in North China Plain, and saline water with salinity (EC(iw)) from 1.1 to 10.9 dS/m was applied to irrigate tomato, cucumber, oleic sunflower and waxy corn under mulched drip irrigation. Throughout crops growing seasons, the soil matric potential at 0.2 m depth under emitters was kept higher than -20 kPa. The experimental results revealed when three seeds per hole were planted, rate of emergence > 80% can be obtained despite irrigation water salinity up to 10.9 dS/m; yield reduction was 1.4% and 1.7% for waxy corn and oleic sunflower for each unit of increase of EC(iw) above 1.6 dS/m, and was 7.5% for cucumber when ECiw was above 1.1 dS/m; irrigation water salinity lower than 4.9 dS/m didn't affect tomato yield, but yield reduced by 6.7% for each dS/m over 4.9 dS/m; tomato, waxy corn and oleic sunflower, a relatively salt.-tolerant crops, showed a constant or slight increase WUE and IWUE, while cucumber, a relatively salt sensitive crop, showed a decrease of WUE and IWUE with increasing salinity; applying saline water under mulched drip irrigation with salinity as high as 4.9 dS/m didn't result in soil salinization, and when salinity up to 6.9 similar to 10.9 dS/m, soil salinity increased, but could maintain a balance and don't increase year-to-year. Therefore, saline water with salinity from 1.6 to 10.9 dS/m can be applied for crop production with drip irrigation when soil matric potential at 0.2 m depth tinder emitters is kept higher than -20 kPa. |
