不同甘薯品种的耐盐性初探
Preliminary Exploration of the Salt Tolerance of Different Sweet Potato Varieties
摘要
Abstract
[Objective]To explore the salt tolerance of different sweet potato varieties under coastal saline alkali land conditions.[Method]By comparing the differences in agronomic traits,biomass and yield,and salt ion content among various varieties,analyze their salt tolerance and adaptability.[Result]There were significant differences in agronomic traits such as tuber number,leaf number,and main stem length a-mong different sweet potato varieties,among which Jishu 26,Zhanshu 16,and Pushu 32 showed advantages in multiple traits.Jishu 26 has significantly higher fresh potato yield,stem and leaf yield,tuber dry rate,tuber fresh mass,and tuber dry weight than other varieties,demon-strating strong growth ability and photosynthetic efficiency.There were differences in the accumulation of Cl-,Na+,and K+in different parts of sweet potato varieties.Jishu 26,Zhanshu 16,and Pushu 32 accumulated higher contents of C-and K+in most organs,but still maintained high growth performance and yield,indicating their strong salt tolerance.In addition,sweet potato cultivation significantly reduced soil salinity and increased soil nutrient content,indicating that sweet potato has a certain impact on the improvement of saline alkali land.[Conclusion]Jishu 26,Zhanshu 16,and Pushu 32 are suitable sweet potato varieties under coastal saline alkali soil conditions.关键词
