Abstract: In order to explore the optimal havesting model of Triticale,the study analyzed the biological yield and nutrition of Triticale in different cutting period and cutting height using the split plot experiment.The results showed that:1Following with the increasing cutting height,the total dry matter production,dry matter content,NDF and ADF content of Triticale decreased,while the crude protein,total sugar,soluble sugar and starch content increased;2With extended cutting periold,the dry matter content,NDF,ADF,total sugar and starch content of Triticale increased,total dry matter production and soluble sugar content increased to maximum (mid milk stage) and then decreased,while the crude protein content decreased. Using the method of subordinate function to evaluate the comprehensive utilization of Triticale,the optimal cutting period and cutting height for silage were mid milk stage and 10.0 cm respectively,and cutting at elongation stage and 10.0 cm stubble for grass hay or greenfeed.
