【摘要】 用多年生的紫花苜蓿单播草地牧草和多年生无芒雀麦与紫花苜蓿的混播草地牧草,研究牧草种类及调制方法对牧草干燥速度的影响。结果表明,在直接晾晒,喷洒2%碳酸钾,压扁茎秆晾晒和压扁茎秆后再喷洒碳酸钾晾晒4种调制方法中,后3种处理都能加快干燥,以压扁茎秆后再喷洒碳酸钾晾晒效果最好。单播苜蓿和混播草地的牧草中,混播草地牧草干燥速度较单播快,即混播牧草直接晾晒也比单播苜蓿压扁茎秆后再喷洒碳酸钾晾晒处理的效果好。更多还原

【Abstract】 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% K₂CO₃,pressed stems and branches and spraying 2% K₂CO₃ 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.更多还原
