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.
