A salt‐tolerant variety (Chuanqiao No.1) and a salt‐sensitive variety (Chuanqiao No.2) of Tartary buckwheat ( Fagopyrum tataricum [L.] Gaertn.) were used as experimental materials to study the effect of saline soil and amino acids on quality and yield. The treatment concentration of Pro (proline), Glu (glutamic acid), and Asp (aspartic acid) was 30, 60, and 40 μM, respectively. Three kinds of amino acids were sprayed twice on the leaves at seedling stage (30 days after sowing) and flowering stage (50 days after sowing). The results showed that Tartary buckwheat in saline soil is more enriched in calcium (Ca), iron (Fe), zinc (Zn), and selenium (Se), and Tartary buckwheat in saline soil is more nutritious. Under appropriate kinds of amino acids treatment, the seed protein and rutin content of Tartary buckwheat were increased, and the Tartary buckwheat quality can be obviously increased. In particular, amino acids treatment can increase the yield of Tartary buckwheat in saline soil, Asp and Glu are the best in salt‐tolerant variety and salt‐sensitive one and more obvious in salt‐tolerant variety.
