| 摘 要： | 与传统插植方式相比，直播稻无育秧和移栽环节、生产效率高、生产成本低，已逐渐发展成为我国目前广受欢迎的一种重要种植方式.但易倒伏是直播稻生产中存在的关键问题，常常导致水稻减产，甚至绝收，同时降低稻米品质.生产上，氮素用量及运筹是提高直播稻抗倒伏能力的关键途径之一.就直播稻的倒伏类型、氮素对直播稻倒伏的影响、直播稻的氮素吸收特征、优化氮肥管理措施对直播稻抗倒伏的作用加以综述，为直播稻抗倒的氮素调控栽培技术构建提供参考.

Research progress of nitrogen regulation on lodging of direct seeding rice |
| |
| Abstract: | Compared with traditional transplanting methods, direct seeding rice has gradually developed into an important planting method which is widely welcomed in China due to its no raising rice seedlings and transplanting steps, high production efficiency and low production cost. However, lodging is a key problem in the production of direct seeding rice, which often leads to rice yield reduction, even no harvest, and rice quality decrease. In production, nitrogen application rate and operational research are one of the key ways to improve lodging resistance of direct seeding rice. The lodging types of direct seeding rice, the effects of nitrogen on lodging of direct seeding rice, the nitrogen absorption characteristics of direct seeding rice, and the effects of optimizing nitrogen management measures on lodging resistance of direct seeding rice were reviewed, so as to provide reference for the construction of nitrogen regulation and cultivation techniques for lodging resistance of direct seeding rice. |
