中文摘要	为评价不同地膜覆盖技术的适应性和节水增产效果,于2014-2015年,在我国典型的干旱、半干旱雨养农业区设置露地穴播(CK1)、全膜覆土穴播(T1)、旧膜重复利用穴播(T2)、膜侧条播(T3)、露地条播(CK2)5种栽培模式对比试验,研究了不同种植模式对胡麻生育期、经济性状、产量、水分利用效率和经济效益的影响。结果表明:覆膜种植模式促进胡麻出苗提前并缩短其生育期0~7d,干旱年份(2015年)较正常年份(2014年)覆膜促熟效应减弱。T1和T2处理两年的产量均显著高于对照和T3处理。T1和T2处理不同年份下水分利用效率显著高于其他处理。经济效益分析表明,T1和T2处理在两年的收益率中稳居第一和第二位,增收效果显著。因此认为全膜覆土穴播和旧膜重复利用穴播是干旱半干旱地区胡麻适宜的种植模式。
英文摘要	Different planting patterns were designed to investigate linseed (oil flax, Linum usitatissimum L.) yield and water use efficiency in arid and semi-arid rainfed area in 2014 (normal rainfall) and 2015(drought). These patterns included whole field plastic mulching with soil covering the top of mulch and bunch-seeding (T1), bunch-seeding directly on the double ridges and furrows mulched with plastic film system used in maize last season (T2), ridges mulched with plastic and row-seeding in furrow (T3), and two control, uncovered bunch-seeding (CK1) and uncovered row-seeding (CK2). In this study, earlier seedling emergency and shorter growth of duration(0-7d)were observed under mulching cultivation than uncovered plantings in two years. More shortened growth stages (16-20d) but with weaker effects on ripeness were displayed under all the planting models in drought year (2015) than in normal year (2014), and lower yield was obtained in 2015. It was suggested that the yields of linseed were significantly higher and WUE was also remarkably increased (P<0.05) in T1 and T2 patterns than in other 3 patterns. Moreover, income analysis showed that the best and the better profit were gained with T1 and T2 patterns respectively in both years. It was concluded that among the 5 patterns, T1 and T2 were optimal in arid and semi-arid regions with 350 mm rainfall.
