| Abstract: |
| The study was conducted in the Sheep Breeding Pasture-land of City Sanjiao of Qinghai Province,which located in north bank of the Qinghai Lake.The achnatherum splendens seed was studied as the object,and the germination characteristics in the different temperature with 5,10,15,20,25,and 30℃ are compared.The result is as follows: achnatherum splendens seed can't germinate under 5℃.Seed germination rate is ascending with temperature raised from 10 to 25℃ and descending when temperature exceeds 25℃.Therefore,neither low temperation nor high temperation does make for seed germination.The optimal temperature of achnatherum splendens seed's germination is between 20～25℃.The germinant status of achnatherum splendens seed enclosure is better than that out of the fence. |
