摘　　要：[Objective]The paper was to study the effects of mowing on nutrients of forage mulberry.[Method]With forage mulberry as the research object,the effects of mowing stubbles and mowing stages on nutrient content of forage mulberry were studied.[Result]With the increase of mowing frequency,the crude protein and crude ash content of forage mulberry decreased,but the crude fiber content increased,and the quality of forage mulberry decreased correspondingly.The crude protein content decreased most obviously from 25.78%in the first stubble to 21.63%in the third stubble.In the first and third stubble,the nutrients at 28±1 d after the last mowing were higher than that at 38±1 d after the last mowing.That is,with the growth of forage mulberry,the accumulated nutrients were also used for their own growth.[Conclusion]From the perspective of nutrient content,the forage mulberry mowed earlier has higher nutritional value and better palatability.
