Abstract
An experiment was carried out to study the effect of NPK fertilizer,micro-element fertilizer,organic fertilizer application on the yield and nutrient quality of Alfalfa(Medicago sativa L.).A field experiment method was used.The yield of Alfalfa was significantly higher than CK with application of NPK fertilizer,micro-elements fertilizer,organic fertilizer,the yields was increased by 13.70% to 28.71%.The contents of alfalfa's crude protein,crude fiber,crude ash,P,Mn,Mo,B,Co and Se were significantly increased with application of NPK fertilizer,micro-elements fertilizer and organic fertilizer.And the contents of alfalfa's crude fat,Fe,Cu,Zn was also increased.But the content of nitrogen free extract was significantly reduced.The newly planted alfalfa in the low fertility levels soil should be rationally fertilized with NPK fertilizer,micro-element fertilizer and organic fertilizer.
