[Effects of irrigation amount and frequency on soil water distribution and water use efficiency in a cotton field under mulched drip irrigation].

A 2-year (2009 and 2010) field experiment was carried out to investigate the effects of irrigation amount (300, 375, and 450 mm) and irrigation frequency (once every 3-, 7-, and 10 days) on the soil water distribution and cotton water use efficiency (WUE) under mulched drip irrigation in North Xinjiang.
