| 中文摘要: |
| 以西北旱地春小麦代表性品种高原602、定西35、会宁15、陇春12、陇春20等为材料,研究旱地春小麦株型指标与产量形成的关系。结果表明,高产旱地春小麦株型应为:株高8295 cm,穗下节间较长,配置合理,穗下节间占秆长的40%以上;旗叶、倒2叶、倒3叶叶角和弯曲度小,旗叶长宽比例为12∶1,开花期叶面积指数3.5以上。 |

| By using Plateau 602,Dingxi35,Huining15,Longchun12 and Longchun20 as material,the experiment was carried out to study the relationship between plant type indices and yield formation in spring wheat on dryland.The results showed that the plant type indices of high-yield spring wheat were as follows: the plant height was 85100 cm;the ratio of top internode to stem length was larger than 40%; the splaying angle and cambering degree of upper three leaves were little;the ratio of length to width of flag leaves was 12∶1;and the leaf area index at anthesis stage was about 3.5. |
