摘　　要：在不同管理条件下 ,成年公羊毛长生长在 0 2 2 6～ 0 42 4mm/d之间 ,幼年公羊在 0 2 78～ 0 3 13mm /d ;成幼年母羊毛长生长速度在 0 1745～ 0 3 695mm/d之间。每日净毛生长量以成年公羊 (9 93 5～ 2 4 196g/d)最高 ,幼年公羊 (6 687～ 14 919g/d)次之。母羊补饲条件和品质基础好的成年母羊 (4 63～ 15 41g/d)、幼年母羊 (6 3 78～ 13 43 3 g/d)要比补饲水平及品质基础一般的成年母羊 (3 0 2 8～ 7 792 g/d)、幼年母羊 (4 2 0 1～ 9 5 0 9g/d)生长速度快。羊毛生长不同阶段的生长速度和纤维直径存在显著的差异 ,枯草期放牧及枯草期补饲水平、羊只本身的品质基础是影响羊毛生长速度和纤维细度的直接因素。The growth rate of wool staple length and clean fleece weight,and the fiber diameter of fine wool sheep has been observed during different growing seasons under the different management conditions in the high and cold pasturing areas. The growth rate of wool staple length ranges from 0.226mm/d to 0.424mm/d,0.278mm/d to 0.313mm/d and 0.1745mm/d to 0.3695mm/d for adult ram,young rams and ewes(both adult and hoggets) respectively. The clean fleece growth rate of adult ram remains the highest and young rams take the second place,while the ewes take the last. The clean wool of adult ewes (4.63～15.41 g/d) and hogget ewes (6.378～13.433 g/d)with good supplement and good genetic base grew quicker than those adult ewes(3.028～7.792 g/d) and hogget ewes (4.201～9.509 g/d)with less good supplement and genetic base. It is concluded that the wool growth rate and the fiber diameter were significantly different among the different growing seasons. The grazing management and level of supplement and the genetic base of the sheep is the main factors that directly influence the wool growth rate and the wool fineness.
