This study used Ningxia gouqiberry as the material, white film(F), branch chips(B), white film and branch chips(FB) as treatments and tillage as control(CK). The effects of different mulching treatments on soil moisture, soil temperature, water use efficiency and the yield of Gouqiberry have been studied. The results showed that soil moisture in FB, B and F treatments presented the upward trend in 0—40 cm soil layer; in 40—100 cm soil layer, soil water content of F treatment significantly reduced, soil water contents of B, FB presented no significant fluctuations with the increase of soil depth, but the soil water content of FB was significantly higher than CK; in 0—100 cm soil layer, the soil water storage of F was significantly higher than CK at different growth stages, and F and B treatments had no significant difference with CK at the beginning of growth, and were significantly higher than CK in summer fruit and autumn fruit; soil average temperature of F was higher than those of FB, CK and B, increased by 1.3℃, 3.3℃ and 4.4℃, respectively; soil temperature coefficient of variation of F is 0.22, 0.21 for CK, and 0.18 for B and FB; the yields of FB, B and F were 76.06%, 45.78% and 9.65% higher than that of CK; the water use efficiency of FB and B significantly increased by 77.14% and 51.68%, respectively, while the water use efficiency of F was only 3.95% higher than CK. The FB treatment not only significantly improved the soil water storage capacity and improved the heat conditions of the soil surface, provided the stable growth environment for the gouqiberry, but also significantly improved the yield and water use efficiency of gouqiberry.
