中文摘要	为寻求半干旱地区垄沟集雨环保的沟覆盖材料, 改善土壤水分和温度状况, 提高降雨资源利用效率, 采用完全随机设计大田试验, 以玉米和高粱作为供试作物, 以沟无覆盖作为对照, 研究垄沟集雨不同沟覆盖方式(无覆盖、液体地膜覆盖、秸秆覆盖和生物可降解地膜覆盖)对土壤温度、土壤水分、作物产量、水分利用效率等的影响。结果表明, 与沟无覆盖相比, 液体地膜和生物可降解地膜覆盖种植玉米的沟中作物全生育期表层(0~25 cm)土壤温度分别提高0.2 ℃和1.0 ℃, 种植高粱的沟中表层土壤温度分别提高0.2 ℃和1.1 ℃, 秸秆覆盖种植玉米和高粱的沟中表层土壤温度分别降低1.1 ℃和1.3 ℃; 液体地膜覆盖、秸秆覆盖和生物可降解地膜覆盖0~140 cm土壤贮水量种植玉米分别提高0.4 mm、21.5 mm和8.6 mm, 种植高粱分别提高2.3 mm、21.0 mm和10.9 mm。液体地膜覆盖和生物可降解地膜覆盖玉米青贮产量分别提高增加0.4%和10.4%, 玉米籽粒产量分别增加1.6%和11.3%, 玉米地上生物量分别增加0.7%和7.3%; 高粱青贮产量分别增加0.2%和10.9%, 高粱籽粒产量分别增加1.1%和11.8%, 高粱地上生物量分别增加1.6%和9.4%; 秸秆覆盖的玉米青贮产量、玉米籽粒产量、玉米地上生物量、高粱青贮产量、高粱籽粒产量和高粱地上生物量分别减少2.9%、2.2%、1.9%、0.7%、1.4%和1.0%。液体地膜覆盖、秸秆覆盖和生物可降解地膜覆盖种植玉米的水分利用效率分别提高0.9 kg?hm~(-2)?mm~(-1)、0.5 kg?hm~(-2)?mm~(-1)和4.9 kg?hm~(-2)?mm~(-1), 种植高粱分别提高0.3 kg?hm~(-2)?mm~(-1)、0.4 kg?hm~(-2)?mm~(-1)和2.7 kg?hm~(-2)?mm~(-1)。综合分析表明, 生物可降解地膜适宜作为半干旱黄土高原区垄沟集雨沟覆盖材料。
英文摘要	To find suitable environmental protection mulching materials of crop cultivation, improve soil temperature and soil moisture, and to increase rainwater resource utilization in semiarid regions in Northwest China, a randomized complete design field experiment was conducted. The experiment determined the effects of different furrow mulching methods (no-mulching, liquid film mulching, straw mulching, biodegradable film mulching, and no mulching as the control) on soil temperature, soil moisture, crop yield (maize and sorghum) and water use efficiency (WUE) in western hilly region of the Loess Plateau. The results showed that compared with no mulching, top soil (0-25 cm) temperature at furrow bottom profile increased by 0.2 ℃ and 1.0 ℃, respectively, for liquid film mulching and biodegradable film mulching during maize growing season, and by 0.2 ℃ and 1.1 ℃ during sorghum growing season. It also decreased by 1.1 ℃ and 1.3 ℃ for straw mulching during maize and sorghum growing seasons, respectively. Soil water storage increased by 0.4 mm, 21.5 mm and 8.6 mm for liquid film mulching, straw mulching and biodegradable film mulching during maize growing seasons, respectively. It also increased by 2.3 mm, 21.0 mm and 10.9 mm for the three mulching modes during sorghum growing season, respectively. Maize silage yield increased by 0.4% and 10.4% for liquid film mulching and biodegradable film mulching, respectively. Then maize grain yield increased by 1.6% and 11.3% and aboveground dry matter increased by 0.7% and 7.3% under the two mulching modes, respectively. Sorghum silage yield increased by 0.2% and 10.9% for liquid film mulching and biodegradable film mulching, respectively. Then sorghum grain yield increased by 1.1% and 11.8% and aboveground dry matter increased by 1.6% and 9.4% under the two mulching modes, respectively. Whereas, under straw mulching condition, the silage yield, grain yield and aboveground dry matter decreased, respectively, by 2.9%, 2.2% and 1.9% for maize planting, and decreased by 0.7%, 1.1% and 1.0% for sorghum planting, respectively, compared with those under no-mulching treatment. The WUE of maize increased by 0.9 kg?hm~(-2)mm~(-1), 0.5 kg?hm~(-2)mm~(-1) and 4.9 kg?hm~(-2)mm~(-1), respectively, and sorghum WUE increased by 0.3 kg?hm~(-2)mm~(-1), 0.4 kg?hm~(-2)mm~(-1) and 2.7 kg?hm~(-2)mm~(-1), respectively, under liquid film mulching, straw mulching and biodegradable film mulching modes, compared with those under the control. Based on the results of crop yield, WUE and environmental protection benefits, the biodegradable film was a suitable furrow mulching material in ridge-furrow rainwater harvesting systems in the semiarid Loess Plateau regions.
