摘要
土壤盐碱化严重影响了土壤的理化性质,玉米作为重要的粮食作物之一,耕地盐碱化程度的逐年加剧严重影响了玉米的产量和品质。为提高在盐碱化土地上玉米的生物产量,进行玉米的耐盐育种十分必要。文章主要分析了盐胁迫对玉米生长的影响、玉米耐盐性的表观适应性、提高玉米抗盐性的途径等研究内容,为促进玉米耐盐育种的开展奠定理论基础。
Soil salinization seriously affects the physical and chemical properties of soil.Maize is one of the important food crops in China.The increasing salinization of cultivated land seriously affects the yield and quality of maize.In order to improve the biological yield of maize on saline-alkali soil,it is necessary to carry out salt tolerance breeding of maize.In this paper,the effects of salt stress on maize growth,apparent adaptability of maize salt tolerance and ways to improve maize salt tolerance were reviewed,which laid a theoretical foundation for promoting maize salt tolerance breeding.
