摘要： 藜麦在中国的种植刚刚起步，尚处在引种和试种植阶段，虽在品种选育、栽培模式、种植密度等方面有些研究，但在水分管理和肥料利用上鲜有报道。‘条藜1 号’是条山农林科学研究所培育的藜麦新品种，本试验对该品种不同氮肥施用量及基追比对产量、经济性状及经济效益的影响进行了研究，结果表明：施氮对藜麦有明显的增产作用，而适宜的氮肥施用量及基追比例是藜麦高产的重要因素，当施氮量为60 kg/hm2、基追比为1:2时，藜麦植株的各项性状指标表现良好、产量和经济效益最高。

Abstract: The plantation of quinoa has just started in China and it is still in the stage of introduction and preliminary production so far. Most of the researches on quinoa have focused on variety breeding, cultivation mode and planting density etc., but the water management and fertilizer utilization were rarely reported.‘Tiaoli No.1’is a new quinoa variety which is cultivated by Tiaoshan Institute of Agriculture and Forestry Sciences, the effects of nitrogen application rate and ratio of base to topdressing on quinoa’s yield, economic characters and economic benefits are studied. The results show that the application of nitrogen fertilizer could significantly increase the yield of quinoa, and proper nitrogen application rate and ratio of base to topdressing are the important factors for high yielding of quinoa. The performance traits of quinoa plants are good, the yield and economic benefits are the highest when the nitrogen application rate is 60 kg/hm2 and ratio of base to topdressing is 1:2.
