摘　　要：[目的]研究不同施肥量与栽培密度对‘龙大麻3号’经济性状及产量影响。[方法]以‘龙大麻3号’为试验材料,采用正交试验法设计,3次重复,记录分析其经济性状及产量。[结果]种植密度在300万株/hm^(2),氮磷钾施用量分别为180、70、140 kg/hm^(2)时的产量最高。[结论]为工业大麻栽培肥料使用提供理论基础,为实现良种良法一体化推广提供依据。[Objective]The aim was to study the effects of different fertilization and planting density on economic characters and yield of"Longda 3".[Methods]Economic characters and yield of‘Longda 3’were recorded and analyzed by orthogonal design.[Results]The highest yield was obtained when the planting density was 3 million plants/hm^(2),the application rates of N,P and K were 180,70 and 140 kg/hm^(2) respectively.[Conclusion]The experiment provided a theoretical basis for the application of fertilizer density in the cultivation of industrial hemp and improved varieties and methods.
