中文摘要	通过田间试验,研究了西南区秸秆还田覆盖与不还田无覆盖2种条件下免耕、垄作轮耕、播前耕整和增施秸秆覆盖4种土壤耕作措施玉米田的土壤物理性状、水分利用及产量。结果表明,秸秆还田与播前耕整相结合,可有效降低土壤密度和土壤紧实度,提高田间持水率。全生育期内,秸秆还田处理下0~100 cm土层平均土壤含水率比相应的秸秆不还田处理高2.5%。无论秸秆还田还是秸秆不还田条件下,播前耕整、垄作轮耕的土壤含水率均较高。秸秆不还田处理全生育期耗水量较秸秆还田处理平均高7.1%。秸秆还田+播前耕整(深松)处理在产量及产量性状等方面优于其他处理,其水分利用效率比秸秆不还田+免耕处理提高46.8%。采用秸秆还田+播前耕整的耕作措施,可一定程度改良西南区土壤理化性状,促进高产、节水。
英文摘要	Field experiment was conducted to investigate the effects on soil physical characteristics, water use efficiency and yield of maize under 4 tillage treatments including no-tillage,ridge rotation tillage, pre-sowing rototilling-tillage (subsoiling),and additional application of straw mulching with and without maize stalk returning in Southwest China. Results showed that soil bulk density and soil compaction significantly decreased while water holding capacity increased under pre-sowing rototilling-tillage with stalk returning. Mean soil water content in 0 ?100 cm with stalk returning was 2. 5% higher than that without stalk returning. Soil water contents under pre-sowing rototilling-tillage and ridge rotation tillage were significantly higher than those under no-tillage despite of the stalk returning treatments. Water consumption in the whole growing season of maize was 7. 1% higher with stalk returning than that without stalk returning. Nevertheless, pre-sowing rototilling-tillage (subsoiling) had significant advantages of grain yield and yield components compared with the other treatments, whose water use efficiency increasd by 46. 8% compared with no-tillage without stalk returning. Therefore, tillage practice such as pre-sowing rototilling-tillage (subsoiling) is a promising approach, which has great practical significances to improve soil physical characteristics,and promote the increases of yield and water use efficiency in arid areas of Southwest China.
