| 摘 要： | 测定了可可西里国家级自然保护区内紫花针茅草地型和高山嵩草草地型牧草,冷季9月份和4月份营养成分。结果表明,各种牧草营养成分含量随种类不同和生长季节迁移而呈现一定差异;9月份两类草地型牧草DM,CP,EE,NDF,ADF,ADL,Ash,Ca和P平均含量分别为92.20%和90.42%,5.40%和5.98%,2.90%和3.06%,48.30%和44.3%,41.40%和34.36%,3.68%和6.52%,18.85%和8.28%,1.43%和1.25%,0.38%和0.47%;4月份两类草地型牧草DM,CP,EE,NDF,ADF,ADL,Ash,Ca和P平均含量分别为94.33%和93.75%,3.69%和5.85%,1.52%和2.32%,66.82%和61.88%,47.14%和43.32%,9.14%和8.53%,13.48%和13.47%,1.38%和1.16%,0.38%和0.36%;紫花针茅草地型和高山嵩草草地型牧草CP平均含量9月份较4月份分别高出46.8%和35.5%,NDF,ADF和ADL分别降低了27.71%和28.41%,11.95%和20.68%,59.63%和23.33%;就营养品质而言,高山嵩草草地型牧草优于紫花针茅草地型牧草。

| Abstract: | Nutrient content of Stipa purpurea and Kobresia pygmaea forages type were determined during cold reason.The results showed that the nutritive value of herbages are vary with herbage species and seasonal transformation .The average nutrient contents of DM ,CP ,EE, NDF, ADF, ADL, Ash ,Ca and P in S.purpurea and Kobresia pygbmaea in September were (92.20%) and( 90.42%),(5.40%) and (5.98%),( 2.90%) and (3.06%),( 48.30%) and (44.3%),( 41.40%) and (34.36%), (3.68%) and( 6.52%), (18.85%) and( 8.28%), (1.43%) and (1.25%), (0.38%)and (0.47%) respectively. While in April were (94.33%) and (93.75%), (3.69%) and (5.85%), (1.52%) and (2.32%), (66.82%) and (61.88%),( 47.14%) and (43.32%), (9.14% )and (8.53%),(13.48%) and (13.47%), (1.38%) and (1.16%), (0.38% )and (0.36%). The average nutrient contents of CP and EE in September were (46.8%) and (35.5%) higher than those in April. While NDF,ADF and ADL in September were (27.21%) and (28.41%),(11.95%) and (20.68%), (59.63%) and (23.33%) lower than those in April. As a whole, the herbage quality of Kobresia pygmaea type was superior to that of S. purpurea type. |
