    Mulching can affect dryland winter wheat yield and water use by conserving soil water. A study was conducted to examine the effect of surface mulching on dryland soil water content, winter wheat yield, and water use efficiency (WUE) from 2008 to 2012 in the Loess Plateau of China. Treatments included whole-year wheat straw mulching at 9000 kg ha-1 (HSM) and 4500 kg ha-1 (LSM), summer wheat straw mulching at 9000 kg ha-1 (SSM), whole-year plastic film mulching (PFM), and no mulching (CK). In the years with below-average precipitation (2008-2010), mulching increased soil water storage, winter wheat yield, and WUE by 0.2-7.3%, 1.4-8.1%, and 2.0-7.3%, respectively, compared to the no mulching treatment.
