摘　　要：开展盐碱地综合利用对保障国家粮食安全,端牢中国饭碗具有重要战略意义。盐碱胁迫是影响植物生长发育的主要非生物逆境因素之一。桑树是具有广泛抗逆性的药食同源作物,不论是在生态还是经济建设中都具有举足轻重的作用。提高桑树对盐碱胁迫的耐受性,筛选耐盐碱桑树品种,为生物改良盐碱地,提供以种适地的途径,成为目前盐碱区域农业生态修复的一个重要研究方向。综述了盐碱胁迫对桑树生长发育、光合特性和生理性状的影响以及桑树响应盐碱胁迫的分子机制和缓解盐碱胁迫的应对措施的研究进展。在此基础上,还讨论了桑树植物在耐盐性研究中存在的问题,并展望了桑树耐受盐胁迫研究的方向。旨在进一步桑树耐盐机制的解析及耐盐品种的选育提供理论依据,进而为桑树栽培广泛应用于盐碱地治理提供新思路。With the development of economy and society,the improvement of people’s living standards and the continuous upgrading of grain consumption structure,China’s grain supply is in a tight balance as a whole,and the national food security pressure persists,Moreover,the acceleration of industrialization and urbanization has led to an irreversible decline in the quantity and quality of cultivated land in China,and the sustainable utilization and protection of cultivated land are also facing huge pressure and challenges,and the saline-alkali land has become the largest non-traditional cultivated land resource in China that can be transformed and utilized.Therefore,the comprehensive utilization of saline-alkali land is of great strategic significance for ensuring national food security and securing the rice bowl in China.It is an effective biological measure to cultivate saline-alkali tolerant plants and improve their saline-alkali tolerance in saline-alkali land development and technical improvement.It is an urgent need to cultivate and introduce excellent varieties that can adapt to saline-alkali environment,and to explore and cultivate more salt-tolerant plants that have both ecological restoration function and economic benefits.Mulberry is rich in nutrients and functional factors,which is also a medicinal and edible homologous crop and economic tree species with extensive stress resistance.At the same time,mulberry has many varieties,different characteristics,developed roots,lush foliage and strong resistance,which can resist the invasion of cold,drought and flood,and has many functions such as water conservation,wind and sand fixation,air purification and ecological environment improvement.It is one of the ecological tree species with great potential for ecological protection,saline-alkali land management and soil remediation.Mulberry plays an important role in both ecological and economic construction.Therefore,it has become an important research direction of agricultural ecological restoration in saline-alkali
