Introduction: in Naqu area, the largest pasturing area in Tibet, the artificial test of perennial forage on degraded grassland with an altitude of more than 4500m has been successful The experimental base was built in 1998 with an investment of 1.15 million yuan from Tibet Autonomous Region Before the implementation of the project, the annual yield of fresh grass here was only 35 kg to 65 kg per mu, and 21 mu of fresh grass was used to feed a sheep Now, half a year old barley grass, perennial Old awn wheat grass and Pennisetum grass are mixed for sowing, although the resistance of the grassland to road treading is weak, But the yield is high The average yield of the grass on the test field is up to 1200 kg per mu, and one mu of grassland can raise one sheep However, experts believe that planting forage in high altitude areas should be done with caution, especially not in large areas, because once the surface is opened and loosened, if the later management can not keep up with it, it may cause rats, insects and desertification (author:) share to feed Weibo share to:
