| 英文摘要 | A 4-year trial was set up to test the feasibility of growing waxy corn (Zea mays L var. ceratina Kulesh) in a highly saline wasteland with drip irrigation in the Ningxia plain, northwest China. The original soil salinity expressed as electrical conductivity of the saturation paste extract (ECe) averaged 28 dS/m in the 0-120 cm depth. The experiment included five soil matric potential (SMP) treatments in which the SMP at 20 cm depth below the drip emitters was controlled higher than -5, -10, -15, -20 and -25 kPa after waxy corn establishment. The results showed that drip irrigation created a favorable soil condition for waxy corn growth through forming and maintaining a high moisture and low salinity region in the root zone when the SMP was maintained higher than -25 kPa. Waxy corn growth and yield parameters increased with the increase of SMP from -25 kPa to -5 kPa, but their responses to SMP decreased with the prolonged period of cultivation. Irrigation frequency and irrigation amount decreased significantly as SMP decreased from -5 kPa to -25 kPa, and the highest irrigation water use efficiency (IWUE) was available when the SMP was around -15 kPa in 2005, and was between -20 kPa and -25 kPa in successive years. After years of cultivation and drip leaching, the highly saline soil gradually changed to a moderately saline soil. This research suggests that drip irrigation can be successfully used in growing waxy corn in dry and highly saline conditions after appropriate management strategies are adopted.
