Surrounding the implementation of a new round of large-scale yield improvement actions for grain and oil crops, conducting large-scale rice production and efficiency enhancement is an important measure to ensure the absolute safety of China's food supply. However, there are numerous pressures to increase rice production and efficiency on a large scale, such as the fact that rice yield improvement has entered a bottleneck period, a single technology is difficult to effectively increase rice yield, the high-quality rate of rice is low, and the income of rice farmers shows a parabolic downward trend. In response to the challenges of increasing rice production and efficiency on a large scale, this article explores the county-wide promotion path for large-scale improvement of rice production and efficiency, aiming to transform integrated technological innovations into new quality productivity and provide strong technological support for achieving a large-scale increase in rice yield.
