The people regard food as the heaven, and the food is earth-oriented. Cultivated land resources are one of the most basic agricultural production factors, and the quality of cultivated land directly affects national food security and ecological security. Since the reform and opening up, with the rapid development of my country’s industrialization and urbanization, the intensive use of cultivated land resources for many years, coupled with excessive and unreasonable use of chemical fertilizers, has led to a decline in the basic fertility of my country’s cultivated land, soil acidification, salinization and black soil Degradation and other problems are becoming more and more serious. Responding to the problem of farmland degradation is a major proposition of my country’s agricultural scientific research, and it is also one of the key tasks of the national strategy of”hiding grain in the land”. Strengthening the technological innovation of biological nitrogen fixation to help the protection of cultivated land resources and the improvement of cultivated land quality has particularly important practical significance.

Xinjiang Habitat has made progress in the study of deep-rooted legumes’ biological nitrogen fixation in response to salt

Leguminous plants have the potential for nodulation and nitrogen fixation, but in arid areas, the biological nitrogen fixation potential of perennial legumes shows greater spatial variability. Previous studies on the nitrogen metabolism of the deep-rooted perennial herbaceous camel thorns in the transition zone between the Taklimakan Desert and the Cele Oasis found that the biological nitrogen fixation potential of camel thorns showed large spatial variability, and the nitrate reductase activity of nitrogen-fixing plants Significantly lower than non-nitrogen-fixing plants. Based on this inference, this may be due to the differentiation of the camel thorn community in this area into different genotypes, which have different nitrate reduction and nitrogen fixation capabilities, but the correctness of this reasoning needs further verification.
