天津地区饲用小黑麦最佳刈割时期和留茬高度研究
Study on the Optimal Cutting Period and Cutting Height of Triticale in Tianjin
摘要
Abstract
In order to explore the optimal harvesting 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:Following 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;With extended cutting period,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.关键词
