Abstract: In order to promote the dentition, the amount of tillers increasing and grass production of Leymus chinensis, the morphological indicators and nutrient composition of L. chinensis under different fertilizer treatments with three different transplanting methods were studied. The results showed that different fertilization treatments were beneficial for the vegetative growth of of L. chinensis. In the same transplanting method, the numbers of stems, tillers, nitrogen absorption, phosphorus absorption and potassium absorption as well as crude protein, crude fat, ash and yield of T2（N 120 kg/hm²,P₂O₅ 120 kg/hm²,K₂O 60 kg/hm²） were higher compared with the other treatments, and crude fiber and nitrogen-free extract content of T2 treatment were lower than the other treatments. The nutritional value of field seedlings transplanting in L. chinensis was the highest among three transplanting methos. It suggested that appropriate NPK ratio and reasonable cultivation methods could significantly increase the nutritional value and yield of L. chinensis.
