| 中文摘要: |
| 为探索提高滴灌冬小麦产量的适宜播种行距，于2021—2023年设置3种宽窄行和15 cm等行距（CK）田间试验，宽窄行播种行距分别是13.3 cm+13.3 cm+13.3 cm+20 cm（M1）、10 cm+10 cm+10 cm+30 cm（M2）、10 cm+10 cm+10 cm+20 cm（M3），分析不同播种行距对滴灌冬小麦的叶面积指数、干物质积累及产量构成因素的影响。结果表明，宽窄行播种方式能维持小麦较高的叶面积指数，提高干物质积累能力及花后干物质对籽粒贡献能力；M2处理产量最高，为8 984.90 kg·hm-2，分别较CK、M1、M3处理提高了12.16%、6.78%、6.63%。在本试验条件下，10 cm+10 cm+10 cm+30 cm 宽窄行播种更有利于新疆滴灌冬小麦干物质积累和产量的提高。 |

| In order to understand the effect of row width on dry matter accumulation and yield of winter wheat under drip irrigation, three row widths and 15 cm equal row spacing(CK) field experiments were set up from 2021 to 2023, and the wide and narrow rows were 13.3 cm+13.3 cm+13.3 cm+20 cm(M1), 10 cm+10 cm+10 cm+30 cm(M2), and 10 cm+10 cm+10 cm+20 cm(M3), respectively. The effects of different sowing methods on leaf area index, dry matter accumulation and yield components of drip irrigation winter wheat were analyzed, so as to explore the suitable sowing methods to promote the increasing effect of drip irrigation on winter wheat yield. The results showed that wide and narrow row seeding could maintain higher leaf area index, improve dry matter accumulation ability and dry matter contribution ability to grain after anthesis. Among them, M2 had the highest yield(8 984.90 kg·hm-2), which was 12.16%, 6.78%, 6.63% higher than CK, M1 and M3 treatments, respectively. Under the experimental conditions, 10 cm+10 cm+10 cm+30 cm wide and narrow row seeding was more beneficial to the dry matter accumulation and yield of winter wheat under drip irrigation in Xinjiang. |
