中文摘要	本研究通过田间定位试验,探讨了河西绿洲灌区单作小麦、小麦/玉米间作、小麦/大豆间作3种典型春小麦生产模式下,长期留茬免耕播种对春小麦出苗和产量的影响,为该区域春小麦高效可持续生产提供理论依据。结果表明:与传统翻耕相比,留茬免耕播种小麦/玉米和小麦/大豆间作的小麦出苗率、出苗均匀度下降明显,降幅分别为3.3%~ 8.6%、9.6%~ 20.5%和2.9%~8.8%、10.7%~ 61.7%;单作小麦的出苗均匀度有所提高,其中2019年显著增加14.9%,而出苗率在2020年显著降低4.2%; 3种种植方式下,春小麦麦苗整齐度均有所下降。留茬免耕播种3种种植模式下,春小麦成穗数在收获时均与传统翻耕处理持平,差异不显著。3种模式下的春小麦均可以通过提高穗粒数和千粒重来弱化出苗对产量的影响,在收获时,春小麦籽粒产量的增幅分别为10.3%~12.9%(单作小麦) 、10.5%~11.9%(小麦/玉米间作)和10.3%~22.5%(小麦/大豆间作),均达到显著水平。在农田风蚀退化极其严重的河西绿洲灌区,留茬免耕播种是春小麦生产中切实可行的耕作措施。
英文摘要	We examined the effects of long-term no-tillage sowing with crop stubbles on seedling emergence quality and yield of spring wheat under the three typical spring wheat planting modes of single wheat,wheat-corn intercropping and wheat-soybean intercropping in a long-term field experiment in Hexi oasis irrigated area,aiming to provide theoretical support for the efficient and sustainable production of spring wheat. The results showed that,compared with traditional tillage,no-tillage sowing with crop stubbles significantly decreased seedling emergence rate and emergence evenness of spring wheat in wheat-corn intercropping and wheat-soybean intercropping by 3.3%-8.6%, 9.6%-20.5%,2.9%-8.8%,and 10.7%-61.7%,respectively. Emergence evenness was significantly increased by 14.9% in 2019,while seedling emergence rate was significantly decreased by 4.2% in 2020 under the mode of single wheat compared with traditional tillage. Seedling uniformity of spring wheat seedling stage were reduced under the three typical planting modes,including single wheat,wheat-corn intercropping and wheat-soybean intercropping. Spike number of spring wheat were equal to that of traditional tillage at harvest under the three planting modes of no-tillage sowing with crop stubbles,and the differences were not significant. Effects of seedling emergence rate of spring wheat on yield was weakened by increasing grain number per spike and 1000-grain weight of spring wheat under the three planting modes. Grain yield was significantly increased by 10.3%- 12.9% (single wheat),10.5%-11.9% (wheat-corn intercropping),and 10.3%-22.5% (wheatsoybean intercropping) at harvest,respectively. Our results indicated that no-tillage sowing with crop stubbles was the feasible tillage mode in the production process of spring wheat in Hexi oasis irrigation area with extremely serious farmland wind erosion degradation.
