Abstract

Saline-alkali land is a valuable land resource that can be developed and utilized, and improving crop adaptation to saline-alkali environments is crucial for alleviating global food security pressure and promoting sustainable agricultural development. Agricultural biotechnology, as a core driving force for agricultural innovation, has provided efficient and precise technical means for crop improvement in saline-alkali lands. This paper systematically reviews the latest research progress of agricultural biotechnology (including genetic engineering, molecular marker-assisted breeding, omics technology, and microbial biotechnology) in crop saline-alkali tolerance improvement. It analyzes the technical principles, application effects, and existing problems of various biotechnologies, and discusses the integration strategies of multiple biotechnologies in saline-alkali tolerant crop breeding. Furthermore, the future development trends and application prospects of agricultural biotechnology in saline-alkali land crop improvement are prospected. This study provides important technical support and theoretical reference for accelerating the development and utilization of saline-alkali land resources and promoting the sustainable development of agriculture in saline-alkali regions.
