![]() ![]() ![]() Compared with CK, PMP and PMF significantly increased soil temperature by 1.30–1.31 ☌ and 0.76–1.00 ☌, soybean grain yield by 38.6–39.0 % and 38.8–44.2 %, and water use efficiency (WUE) by 27.7–32.8 % and 30.8–37.5 %, respectively, while SM significantly decreased soil temperature by 0.96–1.15 ☌, and increased grain yield by 21.8–25.4 % and WUE by 16.9–21.9 %. The SM, PMF, and PMP treatments had 12.3–12.5, 16.8–22.1, and 23.2–24.2 mm higher soil water consumption (0–120 cm depth) than CK, most of which occurred in the 60–120 cm soil layer. The mulching treatments (PMP, PMF, and SM) increased soil water consumption and soil water use efficiency. We investigated the effect of straw strip mulching and film mulching on soil water consumption, temperature, growth, grain yield, and economic income of soybean from 2017 to 2018 in Qingyang on the semi-arid Loess Plateau in China using four treatments: (a) alternating ridges and furrows with ridges mulched with white polyethylene film (PMP), (b) alternating flat and bare land with only the plat mulched by white polyethylene film (PMF), (c) alternating strips mulched with maize ( Zea mays L.) straw (SM), and (d) traditional land planting without mulching (CK). Judicious mulching management can improve water conservation practices to alleviate this issue while increasing crop productivity. Water shortages threaten agricultural sustainability in the semi-arid areas of the Loess Plateau. ![]()
