Abstract

The purpose of this paper is to explore the selection and utilization strategies of crop saline-resistant germplasm resources in order to cope with the severe challenge of global saline-alkali land expansion to agricultural production. Firstly, by summarizing the origin and distribution of saline-alkali land and its adverse effects on crop growth, the urgency and importance of the study were clarified. Then, the concept, characteristics and existing screening and utilization methods of saline-alkali resistant crop germplasm resources were described in detail. In terms of screening steps, a systematic process from sample collection, preliminary screening, in-depth identification to stability verification was proposed to ensure the selection of excellent germplasm with high saline-alkali resistance. Further, this paper discussed the utilization ways of saline-alkali resistant germplasm resources in variety improvement, extension of planting, ecological restoration and industrial chain extension. In particular, through the mining and utilization of saline-alkali resistant genes, the innovative application of cross breeding technology, and the construction of modern agricultural extension system, a new idea is provided for the sustainable development of saline-alkali land agriculture. In addition, this paper also emphasizes the importance of ecological restoration and environmental protection, and puts forward ecological restoration strategies and biodiversity restoration measures for saline-alkali land, in order to achieve carbon sink increase and climate change response while alleviating environmental pressure. Finally, this paper looks forward to the potential of saline-alkali resistant crops in the extension of the industrial chain, including product deep processing, brand building and market expansion, as well as the integration of agricultural tourism and cultural experience, which points out the direction for the diversified development of agricultural economy in saline-alkali land.

Keywords:Saline-alkali resistant crops; Germplasm resources; Screening and utilization; Ecological restoration; Variety improvement
