Recently, the agro-ecological team of Huazhong Agricultural University combined the methods of meta big data analysis and field control experiments to comprehensively analyze the effects of nitrogen fertilizer application amount and application period on rice yield and quality, and pointed out that the total amount of nitrogen fertilizer application and the reduction of nitrogen fertilizer should be appropriately reduced. The amount of spike and grain fertilizer can significantly improve the eating quality of rice without affecting the yield.

The Chu Chengcai research group of the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences conducted a comprehensive agronomic character identification of 110 early rice farm species collected in 52 countries (regions) in different geographic regions of the world over the past 100 years, and found that under different nitrogen fertilizer conditions, Among many agronomic traits, there is a high correlation between the nitrogen response ability of rice tiller (branch) and the variation of nitrogen use efficiency. The research team used genome-wide association analysis technology to identify a rice nitrogen efficient gene OsTCP19, which acts as a transcription factor to regulate rice tillering.
