| Abstract: | Salt tolerance of nine legume forages during germination and seedlings was studied with 0.6%,0.9%,1.2%,1.5% and 1.8% mixed salt solution(71%NaCl,3%CaCl2,4%MgSO4,22%K2SO4) based on the germinating stage,germination rate,seedling height and root length,germination trend,seed vigor with the membership function.The results showed that the salt tolerance ability of nine forages was in order of Astragalus adsurgens>Medicago sativa cv.Zhongmu No.3>Galega orientalis>Coronilla varia>Lotus cornioulatus>Melilotus ruthenicus>Astragalus cicer>Trifolium repens>Medicago falcata. |
