英文摘要 | To improve global food security, techniques for sustainability managing salinity are needed. The objective of this study was to find a sustainable cultivating method for grain production using saline groundwater. A field experiment was conducted to determine the effect of drip irrigation with saline water (EC = 9.5 dS m(-1)) (DIS), drip irrigation with freshwater (electrical conductivity [EC] = 1.3 dS m(-1)) (DIF), and flood irrigation with freshwater (CK) on sunflower (Helianthus annuus L.) yields. The cultivation pattern of "scheduled drip irrigation + mulched ridge" was adopted in DIS and DIF, while that in CK was the local pattern of "flood irrigation + flat mulch". Results showed that drip irrigation with saline water and drip irrigation with freshwater saved 95% and 43 freshwater when compared with CK. After 2 yr, soil electrical conductivity of saturated paste extracts (ECe) in the surface 40 cm decreased from 22.9 to 6.4 dS m(-1) in DIS and from 17.9 to 5.4 in DIF. The calculated desalinization rates were 72.1% for DIS and 69.3% for DIF. The sunflower yield in DIS and DIF increased by 12.1 and 37.0% and the economic benefit correspondingly increased by 29.6 and 52.5% when compared with CK after 2 yr. The drip irrigation with saline groundwater had remarkable advantages in saving freshwater, leaching salt, and increasing income. |
