Abstract
The effects of combined application of nitrogen and phosphorus fertilizer on the quality,grass yield and nutrient uptake of Leymus chinensis were analyzed at the west beach of Yanchi county in Ningxia.The results showed that the grass yield of Leymus chines ‘Zhongke No.2'fertilized 120kg·hm-2 N with the base fertilizer of 120kg·hm-2P2O5 increased 1.5times compared to control.The grass yield of Leymus chines ‘Zhongke No.2'significantly increased after fertilizing more nitrogen(P0.05).The uptake of nitrogen,phosphorus and potassium firstly increased and then decreased with the increases of nitrogen and phosphate.Rational fertilization could effectively increase the crude protein content of Leymus chinensis,and lower the content of nitrogen-free extractum.The quality of Leymus chinensis was the best after fertilizing 90kg·hm-2 N with the base fertilizer of 120kg·hm-2P2O5 and the economic efficiency increased 1.48 times.Therefore,the combined application of 90kg·hm-2 N with the base fertilizer of 120kg·hm-2P2O5 was recommended to be applied in the same region.
