| 摘要: |
| 【目的】研究不同波涌灌溉处理对冬小麦茎秆抗倒伏能力的影响。【方法】采用4种不同的畦灌方式（普通连续畦灌、波涌畦灌、交替间隔波涌畦灌和固定间隔波涌畦灌），研究了不同波涌畦灌处理对冬小麦重心高度、鲜质量、茎秆抗折力、弯曲弹性模量和抗倒伏指数的影响。【结果】不同波涌畦灌处理均能降低重心高度、增加产量；交替间隔波涌畦灌的抗倒伏指数沿长度方向逐渐增大，且在灌浆期茎秆抗倒伏能力较强。【结论】统筹产量和抗倒伏能力，冬小麦长畦灌溉以交替间隔波涌畦灌为宜。 |

| Abstract: |
| 【Objective】 Illustrate stalk lodging resistance mechanisms in the late growth stage of winter wheat. 【Method】 4 kinds of border irrigation (continuous border irrigation, surge flow border irrigation, alternating interval surge flow border irrigation and fixed interval surge flow border irrigation) were conducted to study the effect of different surge flow border irrigation on center of gravity height, fresh mass, stalk physical strength , bending elastic modulus and lodging resistance index of winter wheat. 【Result】 Different surge flow border irrigation treatments significantly reduced the gravity center height and improved the grain yield. The lodging resistance index with alternating interval surge flow border irrigation was bigger in the milky stage and gradually increased along the length direction. 【Conclusion】 Overall the grain yield and lodging resistance, alternating interval surge flow border irrigation is appropriate for long furrow irrigation. |
