| Abstract: | Salt tolerance of 7 Gramineous pastures during germination and seedlings has been studied with 0.6%,0.9%,1.2%,1.5% and 1.8% mixed salt solution(71%NaCl,3%CaCl2,4%MgSO4,22%K2SO4).The membership function was applied according to the germinating stage,germination rate,seedling height and root length,germination trend,seed vigor etc.The results showed that the salt tolerance ability among 7 plants was in order of Festuca.arundinacea>Agropyron elongatum>Puccinellia tenuiflora>Poa crymophila>Horcleum brevisubulatum>Agropyron morgolicum>Elymus duhuricas. |
