摘要
本文研究了西藏绒山羊日土型、尼玛型和紫绒型被毛纤维中绒的直径和自然长度、毛的直径和长度、绒毛比。日土型羊绒的直径、自然长度均高于尼玛型和紫绒型,日土型和尼玛型羊的绒毛重量比高于紫绒型,而3种类型的绒毛根数比无显著差异(P>0.05)。绒的直径与自然长度、产绒量呈正相关,而且相关关系显著(P<0.05)。
Down diameter and staple length,hair
diameter and length,ratios of down to hair in weight number and diameter ,and relationship
between down diameter and down staple length,down production of Ritu Type(RTG),Nima
Type(NTG)and Violet Down Type(PTG)of Tibetan cashmere goat were investigated in this paper.
Down diameter and staple length in RTG were higher than in NTG and PTG.Weight ratio of down
to hair in TRG and NTG were higher than in PTG.There was no difference in number ratio of
down to hair among the three types of goats(P>0.05).There were positive correlation between
down diameter and down staple length,down producton in RTG(P<0.05).
