不同搂草方式对苜蓿草品质的影响

THE EFFECT OF DIFFERENT HUGGING METHODS ON THE QUALITY OF GRASS

本试验在相同的条件下,采用栅栏式搂草机和指针式搂草机搂草,搂草后测定苜蓿草条水分动态变化、草条茎叶比、RFV、粗蛋白、灰分,草捆水分。结果表明:栅栏式搂草机搂草较指针式搂草机搂草能够有效提升草条干燥速率,显著提高苜蓿相对饲喂价值和叶茎比,但对苜蓿粗蛋白、草捆水分、灰分没有显著影响。栅栏式搂草机能有效减少叶片损失,提高苜蓿草品质。

In order to find out the modulation process of alfalfa hay,fence-type lawnmower and pointer-type mower grass-hugging effect,this experiment in the same conditions,the use of fence-type lawnmower and pointer-type mower hugging grass,after hugging grass to determine the dynamic change of grass moisture,grass bale moisture,grass stem leaf ratio,RFV,crude protein,ash.The results show that the fence-type mower can effectively improve the drying rate of grass strips compared to the pointer-type mower,which indicates the relative feeding value and leaf stem ratio,but has no significant effect on the coarse protein,grass bale moisture and ash.Fence-type mowing machine can effectively reduce the loss of leaves,indicating the quality of the grass.
