On the basis of clean cultivated pasture of perennial lucerne and mixture pasture of perennial awnless brome and lucerne,the effect of pasture species and mixing method on pasture drying rate was analyzed.The results showed that among sunshine,spraying 2% K_2CO_3,pressed stems and branches and spraying 2% K_2CO_3 after pressed stems and branches,the latter three groups could accelerate the drying rate,and the forth group was the best.Compared with the clean cultivated pasture,the mixture pasture was dried faster in every group.The mixture pasture was dried,without any control,even faster than the clean cultivated pasture with the forth control.
