| Abstract: | The domestication and cultivation of local wild Deschampsia caespitosa have been studied .The results showed that Deschampsia caespitosa could finish the whole growth period from second planting year under artificial cultivation at the altitude is about 3 800m in Guoluo region. The number of growth days is about 130, the year of cultivation grows slowly. In second years grows quickly, In third years growing peak, plant height can reach 81.6 cm, coverage reached 98.0%, the rate of overwinter reached 99.0%, the hay yield and seed yield were 4426.2 kg/hm 2 and 482.8 kg/hm 2 respectively. It showed good ecological and cultivation performance with abundant leaves, good palatability, suitable for both mowing and grazing, and can be used as a good and pioneer seed for vegetation restoration and reconstruction of degraded grassland in alpine meadow. |
