chinois. 研究氮磷钾肥、微肥、有机肥三者配施对紫花苜蓿饲草产量和品质的影响。采用田间试验。结果表明：几种配施肥料能显著提高紫花苜蓿饲草产量,与未施肥处理相比,施肥处理饲草产量增幅为13.70%～28.71%,且氮磷钾肥、微肥、有机肥配施效果显著优于氮磷钾肥和微肥,氮磷钾肥、微肥、有机肥三者配施效果最好,显著优于其他处理;能显著提高紫花苜蓿粗蛋白、粗纤维、粗灰分、磷、锰、钼、硼、钴、硒的含量,促进紫花苜蓿粗脂肪、铁、铜、锌含量的提高,且氮磷钾肥、微肥、有机肥三者配施效果最好,显著优于未施肥处理,导致了紫花苜蓿无氮浸出物含量显著降低。在肥力水平不高的土壤上,对初种植的紫花苜蓿应合理配施氮磷钾肥、微肥和有机肥。

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.
