Abstract
By selecting different genotypes varieties and setting up different drip irrigation amount, the data about water consumption characteristics and yield traits of spring wheat in southern Xinjiang arid area were obtained and analyzed, the results showed that: (1)Water consumption amount in drip irrigation filed of spring wheat mainly focused at the middle-late growth stage and water consumption strength reached the maximum value of 5.18-7.52 mm/d during booting and flowering period; (2)The amount of drip irrigation mainly affected grains per spike and grain weight. Excessive irrigation caused by the increase in amount and strength of water consumption and a decline in Water Use Efficiency (WUE) decreased; Deficit irrigation resulting in the field water stress, influenced wheat growth, finally led to a seriously decline in production. Appropriate irrigation could effectively regulate growth of plants, optimize phase allocation of water consumption, guarantee a high water consumption intensity during jointing-flowering stage, which was favorable to the growth of reproductive organs, so the WUE was the highest, reaching 13.75-15.21 kg (hm2/mm).(3) Water consumption characteristics showed difference among the varieties. With the maximum values of yield of 6388.7 kg/ha and WUE of 15.21 kg (hm2/mm) in appropriate water treatment, 181.1 kg/ha and 1.89 kg (hm2/mm) more than Xinchun 19, respectively, Xinchun 22 was a water-saving and high efficiency variety.
