| 英文摘要 | The decreasing of available farmland makes saline soil a valuable alternative land sources for agriculture in North West China. In order to obtain high yields and economic benefits, it is very stringent to develop suitable management procedures for farms to better cope with soil water moisture and salinity. A field experiment was carried out to investigate the effect of soil matric potential on waxy corn growth and water use under drip irrigation in saline soils of North West China in 2005. The experiment included five treatments, which controlled soil matric potential (SMP) at 20cm depth immediately under emitter higher than -5, -10, -15, -20, -25kPa. There were significant differences among the five treatments on waxy corn growth. The higher the target SMP value was, the higher the yields of waxy corn. Plant height, stem circumference, LAI and above-ground biomass all increased with increasing of SMP value, but the highest irrigation water use efficiency was achieved with SMP of -10kPa. The SMP of -10kPa at 20cm depth immediately under drip emitter can be used as an indicator for corn drip irrigation scheduling on saline soil in the and areas of North West China. |
