中文摘要:
      为确定适宜的地下滴灌毛管埋深与配套耕作方式，以关中地区冬小麦-夏玉米轮作区为研究对象，设置5种不同毛管埋深（0、10、20、30、40 cm）和2种耕作方式（旋耕和免耕），分析了不同处理对冬小麦-夏玉米生长和产量的影响。结果表明：与地表滴灌相比，地下滴灌促进了冬小麦-夏玉米生长及产量的形成。毛管埋深40 cm处理减缓了冬小麦-夏玉米前期株高和叶面积生长（2.42%~21.03%），显著降低了夏玉米干物质积累（8.47%）。与地表滴灌相比，冬小麦、夏玉米产量增幅分别为3.55%~7.68%和2.53%~5.16%。毛管埋深为30 cm和40 cm时，不同耕作方式处理之间无显著差异（P＜0.05）。综合考虑田间生产实践，免耕与毛管埋深30 cm地下滴灌组合可作为关中地区冬小麦-夏玉米轮作较为适宜的种植模式。
英文摘要:
      To determine the optimal burial depth for subsurface drip irrigation capillaries and the corresponding cultivation methods, the study focused on the winter wheat\|summer maize rotation area in the Guanzhong region. Five capillary burial depths (0, 10 cm, 20 cm, 30 cm, and 40 cm) and two cultivation methods (rotary tillage and no\|tillage) were set up, and their effects on the growth and yield of winter wheat and summer maize were analyzed. The results indicated that compared with surface drip irrigation, subsurface drip irrigation had a promoting effect on the growth and yield of winter wheat\|summer maize. The capillary burial depth of 40 cm treatment slowed down the early plant height and leaf area growth of winter wheat\|summer maize (2.42%~21.03%), and significantly reduced the dry matter accumulation of summer corn (8.47%). Compared with surface drip irrigation, the yield increase of winter wheat\|summer maize was 3.55%~7.68% and 2.53%~5.16%, respectively. When the capillary burial depth was set to 30 cm or 40 cm, no significant differences were observed between the various cultivation methods. Considering field production practices, the combination of no\|tillage and underground drip irrigation with a capillary burial depth of 30 cm is recommended as a more suitable planting method for the winter wheat\|summer maize rotation system in the Guanzhong region.
