Solar radiation has a substantial influence on winter wheat (Triticum aestivum L.) growth and water consumption. To elucidate the effect of solar radiation on the yield and water consumption of winter wheat, two-season pot experiments were conducted at Xi’an University of Technology in China from 2015 to 2017. Four shading treatments and a non-shaded control (CK) treatment were applied using black shading net, including 80% (L80), 60% (L60), 40% (L40), and 20% (L20) of the CK. With the increase in the shading degree, the time of winter wheat growing stage was prolonged, but the dry matter accumulation and water consumption decreased. The maximum of the water consumption and water consumption intensity for the winter wheat occurred at the filling stage, and the water-saving rate was higher than the shading rate from heading to the mature period under the L80 treatment. The water-use efficiency (WUE) under the L80 treatment and CK did not differ significantly. The harvest index for the L80 treatment was higher than that of the CK. To obtain high WUE, wheat must not receive less than 80% of solar radiation.
