Research Focus:
Biological nitrogen fixation is a low-energy, non-polluting form of nitrogen supply unique to leguminous plants. The roots of leguminous plants interact with nitrogen-fixing rhizobia to produce nodules for biological nitrogen fixation, reducing nitrogen in the air to ammonium nitrogen that can be absorbed by plants. Especially in the environment of low concentration of nitrogen in the soil, leguminous plants can maximize the ability of biological nitrogen fixation, and adapt to the stress caused by low nitrogen through nodule nitrogen fixation, while the environment of high concentration of nitrogen inhibits nodulation and nitrogen fixation. It can be seen that it is of great significance to fully explore the biological nitrogen fixation mechanism of leguminous plants and improve the efficiency of nodulation and nitrogen fixation to reduce agricultural input, maintain green environmental protection and reduce pollution, and promote sustainable agricultural development.
