Abstract

The expansion of saline-alkali land area and the aggravation of soil secondary salinization have become major constraints affecting global agricultural sustainability and food security. Agricultural biotechnology, as an innovative means to break through the bottleneck of traditional saline-alkali land improvement, has achieved remarkable breakthroughs in recent years in the aspects of salt-alkali tolerant crop breeding, soil microecological regulation, and integrated improvement of saline-alkali land. This paper focuses on the innovative progress of agricultural biotechnology in crop improvement on saline-alkali lands, including the innovative application of gene editing technology, the development of functional microbial resources, the optimization of multi-omics joint analysis technology, and the construction of integrated improvement models of biotechnology and agronomic measures. On this basis, the practical challenges faced by the industrialization application of agricultural biotechnology in saline-alkali land crop improvement are deeply analyzed, such as technical localization, cost control, industrial chain construction, and policy support. Finally, targeted countermeasures and suggestions are put forward to promote the industrialization development of agricultural biotechnology in saline-alkali land crop improvement, and its application prospects in ensuring food security and promoting sustainable agricultural development are prospected. This study provides a new perspective and practical reference for the in-depth application of agricultural biotechnology in saline-alkali land governance and crop improvement.
