摘 要:为了降低西北地区海拔高、风沙大、气候干燥、紫外线强等不利环境因素对羊毛生产的影响,研究为细毛羊穿上一种特制的罩衣,至第2年剪毛时取下罩衣,采集羊毛纤维样品,进行羊毛纤维检验和试纺检验。结果表明:给细毛羊穿罩衣后,羊毛纤维长度平均增加0.33 cm,个体净毛率提高12.44个百分点,个体羊毛纤维产量提高0.44 kg,羊毛中脂含量提高6.44个百分点,毛丛污染深度下降3.10 cm,灰尘含量下降21.25个百分点。说明给细毛羊穿罩衣是一种可以有效提高羊毛纤维产量和质量的途径。To reduce the effects of adverse environmental factors on the wool production, such as higher altitude, big sand blown by the wind, dry climate, and strong ultraviolet radiation in the northwestern region of china, the special overelothes made of polypropylene were put on ex- perimental fine -wool sheep until the shear period in the next year, and then the wool fiber samples were collected and used for the testing of staple and yarn spinning.. The result showed that after dressing for the sheep, the average increase in staple length of wool, the individual clean wool rate, the individual wool fiber yield, and the grease length of wool, were increased by 0.33 cm, 12.44% , 0.44 kg, and 6.44% , respec- tively. And at the same time, the individual polluted staple depth and dust content were reduced by 3.10 cm and 21.25%, respectively. The results indicate that the method of overclothes for fine - wool sheep is an effective pathway to raise wool yield and quality.
